Internet connection problems often lead people to reset their modem, but not every type of reset is the same. A simple restart or power cycle usually restores the connection within a few minutes. A factory reset may take longer because the modem must restore its default settings and reconnect to the internet service provider. Depending on the equipment and provider, it may also need to download configuration information or complete additional setup. Understanding these differences can help you choose the appropriate reset method and avoid erasing settings unnecessarily.
Quick Answer
Restarting or resetting a modem usually takes approximately 2 to 10 minutes. A basic restart or power cycle commonly takes 2 to 5 minutes, while a factory reset may take 5 to 10 minutes or longer. Reconnection can be delayed by provider outages, signal problems, equipment issues, or firmware and configuration updates. If the modem includes a built-in router, a factory reset may also erase customized Wi-Fi names, passwords, and other network settings that must be restored afterward.
Restart vs. Reset a Modem
The terms restart, reboot, power cycle, and factory reset are sometimes used interchangeably, but they do not always describe the same action. Understanding the difference can help you choose the correct troubleshooting step and avoid accidentally erasing customized settings.
Restart
A restart shuts down and starts the modem again without intentionally changing its saved settings. It may be initiated through the modem’s application, online account, administration page, or power controls, depending on the equipment and internet provider.
Restarting refreshes the modem’s connection and is commonly the first step used to address a temporary internet problem.
Reboot
A reboot generally means the same thing as a restart. The modem reloads its operating software and reestablishes its connection to the internet provider without returning its settings to their factory defaults.
Some manufacturers and providers use restart and reboot differently in their instructions, so follow the wording provided for the specific equipment.
Power Cycle
A power cycle involves disconnecting the modem from electrical power, waiting for the time recommended by the manufacturer or provider—commonly about 30 to 60 seconds—and then reconnecting it.
This allows the equipment to shut down completely before beginning a fresh startup and reconnection sequence. A power cycle may resolve a temporary problem that is not corrected by a software-initiated restart.
Factory Reset
A factory reset returns the equipment to its original default settings. It is different from restarting, rebooting, or power cycling the modem.
On a standalone modem, the provider may need to reprovision or reactivate the equipment after a factory reset. On a modem-router combination, the reset may erase:
- Customized Wi-Fi network names
- Wi-Fi passwords
- Administrator passwords
- Parental controls
- Guest-network settings
- Port-forwarding and other network configurations
Some provider-supplied gateways automatically download the necessary configuration and reconnect. Others may require activation or additional setup. The exact process depends on the equipment and provider.
Which Option Should You Try First?
For most temporary connection problems, begin with a restart or power cycle because these methods normally preserve saved settings. Allow the modem enough time to reconnect fully before taking another step.
Use a factory reset only after checking the equipment instructions, following the internet provider’s guidance, or exhausting safer troubleshooting steps. Do not press and hold a recessed Reset button unless you intend to restore the equipment to its factory defaults.
Average Modem Reset Time
Most modem restarts and resets take approximately 2 to 10 minutes, although provider problems, firmware updates, activation requirements, or manual network setup can extend the total time.
| Reset or reconnection step | Typical time |
| Basic modem restart or reboot | 2 to 5 minutes |
| Power cycle, including the waiting period | 3 to 6 minutes |
| Factory reset and basic reconnection | 5 to 10 minutes or longer |
| Separate router restart | Approximately 2 to 5 additional minutes |
| Provider activation or reprovisioning | Additional time may be required |
| Firmware or configuration update | Several additional minutes or longer |
These are general estimates rather than guaranteed completion times. Equipment models, connection types, signal conditions, and internet-provider procedures vary.
Most modems reconnect automatically after completing their startup sequence. A provider-supplied modem or gateway may also download configuration information before restoring service.
If a separate router is connected, wait for the modem to establish its internet connection before restarting or reconnecting the router. Computers, phones, televisions, and other devices may then require additional time to reconnect to the Wi-Fi network.
What Happens During a Modem Reset?
When you restart, power-cycle, or factory-reset a modem, several processes occur before your internet connection is restored. Most happen automatically, but each step adds a little time to the process.
A simple restart retains the modem’s settings. A factory reset returns the modem to its original default settings, so additional setup may be required.
1. The Modem Shuts Down or Resets
During a software-initiated restart, the modem ends its active processes and begins a fresh startup sequence. During a power cycle, electrical power is removed, allowing the equipment to shut down completely and clear temporary operating information.
During a factory reset, the modem also erases customized settings and restores its original default configuration.
2. The Hardware Restarts
After power is restored—or the reset process begins—the modem initializes its internal components and loads its operating software. Status lights may flash, change colors, or turn on and off during this stage.
3. The Modem Performs a Self-Test
Most modems automatically check their basic hardware and software during startup. If the modem detects a problem, startup may pause or one or more status lights may continue flashing or display an error color.
4. The Modem Establishes a Connection
The modem searches for and establishes a connection with your internet provider’s network. The exact process depends on whether you have cable, DSL, or another type of service.
Fiber service commonly uses an optical network terminal rather than a traditional modem, although providers and customers may casually refer to the equipment as a modem.
5. The Modem Is Recognized by the Provider
The internet provider’s network identifies the modem and confirms that it is authorized for the account. If the modem is new, has been factory-reset, or is not correctly registered, activation or assistance from the provider may be required.
6. Configuration Information Is Applied
Depending on the provider and modem, service-related configuration information may be downloaded or reapplied. This can include settings needed to operate the modem correctly on the provider’s network and deliver the subscribed service level.
7. The Signal Synchronizes
The modem establishes and stabilizes its communication channels with the provider’s network. Weak signals, damaged cables, provider outages, or equipment problems can delay or prevent synchronization.
8. Internet Service Is Restored
Once the connection is established successfully, the modem’s online or internet light usually becomes solid. Connected devices can then regain internet access.
If you use a separate router, it may take another minute or two for the router, Wi-Fi network, and connected devices to reconnect fully.
What Can Delay a Modem Reset?
If your modem is taking longer than expected to reconnect, one or more common issues may be slowing the process.
Internet Service Provider Issues
Service outages, maintenance, or other provider network problems may prevent the modem from reconnecting promptly. If the modem cannot communicate with your internet service provider, the restart may appear to stall until service is restored.
Firmware Updates
Some modems automatically receive and install firmware updates during or after startup. These updates may improve security, stability, compatibility, or performance, but they can add several minutes to the reconnection process.
Do not unplug the modem while a firmware update appears to be in progress.
Weak Signal or Loose Cable Connections
Loose, damaged, or improperly connected coaxial, DSL, Ethernet, or power cables can prevent the modem from establishing a stable connection. Signal problems caused by damaged cables, unnecessary coaxial splitters, or problems outside the home may also delay reconnection.
Fiber equipment uses delicate optical cables that should not be sharply bent or repeatedly disconnected.
Router Reconnection
If you use a separate router, it must reestablish its connection after the modem comes back online. Wi-Fi devices may remain offline for another minute or two even though the modem has already reconnected to the internet.
Factory-Reset Setup
A factory reset erases customized modem or gateway settings. The equipment may need to download configuration information, be activated again, or have its network settings reconfigured before service is fully restored.
If the modem also provides Wi-Fi, devices may need to reconnect using the default network name and password printed on the equipment label.
Modem Overheating
An overheated modem may restart slowly, repeatedly disconnect, or shut down temporarily. Keeping it upright when required and placing it in an open, well-ventilated location can help prevent heat-related problems.
Account or Activation Problems
If your internet provider cannot recognize or authorize the modem, the connection may not be restored. This can happen after replacing equipment, changing service, moving the modem to another account, or performing certain factory resets. You may need to activate the modem or contact the provider for assistance.
Aging or Failing Equipment
An older or malfunctioning modem may take longer to start, repeatedly lose synchronization, or never reach a solid online status. If restarts frequently take much longer than normal, the modem may need troubleshooting, replacement, or attention from the internet provider.
What Affects Modem Reset Time?
Several factors influence how long a modem takes to restart and reconnect. Although many restarts finish within a few minutes, the equipment, connection technology, and provider’s network all affect the total time.
Internet Service Provider
Each internet provider uses its own network procedures for recognizing, configuring, and reconnecting customer equipment. Provider maintenance or the way its network handles modem registration can affect how quickly the connection returns.
Modem and Gateway Model
Startup time varies among equipment models. A basic modem may complete fewer startup processes than a combined modem-router gateway that must also restore Wi-Fi, security, routing, and connected-device functions.
DOCSIS Version
Cable modems use a standard called DOCSIS, or Data Over Cable Service Interface Specification, to communicate with the cable provider’s network.
The DOCSIS version affects compatibility, available speeds, and how the modem communicates with the network. However, a newer DOCSIS version does not automatically guarantee a faster restart. Reset time also depends on the modem model, firmware, signal conditions, and provider network.
Internet Connection Type
Cable, DSL, fixed wireless, cellular home internet, and fiber equipment reconnect in different ways. Because each service uses different equipment and communication technology, startup and reconnection times can vary.
Fiber service generally uses an optical network terminal rather than a traditional modem, although the equipment may still need time to reconnect after losing power.
Type of Reset
A simple restart or power cycle usually takes less time than a factory reset. A factory reset erases customized settings and may require the equipment to download configuration information, restore default Wi-Fi settings, or be activated again.
Firmware Version
The modem’s firmware controls how it starts and communicates with the provider’s network. Normal startup time may vary by firmware version. If an update is downloaded or installed during startup, the process can take several additional minutes.
Signal Quality
A strong, stable signal helps the modem establish its connection efficiently. Weak signal levels, line interference, damaged cables, or unnecessary coaxial splitters may cause repeated connection attempts and extend the process.
Modem Condition and Compatibility
Age alone does not determine how quickly a modem starts. However, outdated, unsupported, overheating, or failing equipment may reconnect slowly or have difficulty maintaining a stable connection.
Separate Router
If you use a separate router, it must reconnect after the modem comes online. The modem may already have internet service while the router and Wi-Fi network are still restarting.
Number of Connected Devices
Connected devices generally do not make the modem itself reset more slowly. However, phones, computers, televisions, cameras, and smart-home equipment may take additional time to reconnect after the modem and router are online. Therefore, the modem may finish restarting before the entire household network is fully operational.
What Can Delay a Modem Reset?
If a modem does not reconnect within its normal startup time, a connection or equipment problem may be interfering with the process.
ISP Outage
An outage, maintenance work, or another provider-side problem can prevent the modem from reconnecting. Restarting the modem will not restore service until the provider resolves the underlying issue.
Loose Coaxial or DSL Cable
A loose or damaged service cable can prevent the modem from receiving a stable signal. Check that the cable is securely attached without overtightening the connector.
Damaged Ethernet Cable
A damaged Ethernet cable between the modem and a separate router may leave Wi-Fi devices without internet access even when the modem itself is online. Replacing the cable can help determine whether it is causing the problem.
Firmware Update
A modem may take longer to restart while installing provider-issued firmware. Status lights may flash or change during the update. Avoid unplugging the modem until the update finishes.
Weak or Unstable Signal
Weak signal levels, line interference, damaged wiring, or unnecessary coaxial splitters can cause the modem to make repeated connection attempts. Persistent signal problems may require assistance from the internet provider.
Overheating
An overheated modem may restart slowly, disconnect repeatedly, or shut down. Place it in a well-ventilated location and keep its vents free from dust and obstructions.
Authentication or Activation Problems
The provider may be unable to recognize or authorize the modem, particularly after equipment replacement, an account change, or a factory reset. The modem may need to be reactivated through the provider’s app, website, or customer-support service.
Before Resetting Your Modem
A few simple preparations can prevent lost settings and make it easier to reconnect after the reset.
Check for a Service Outage
Review your provider’s app, website, or outage map before resetting the modem. If there is an outage in your area, resetting the equipment will not restore service.
Decide Whether You Need a Restart or Factory Reset
Try a normal restart or power cycle first. A factory reset should generally be reserved for persistent problems because it erases customized settings.
Save Customized Settings
If you plan to perform a factory reset, record or back up any customized settings your modem or gateway allows you to manage. These may include the Wi-Fi network name, Wi-Fi password, parental controls, port-forwarding rules, and security preferences.
Find the Default Login Information
Locate the equipment label containing the default Wi-Fi network name, password, administrative address, or device access code. You may need this information after a factory reset.
Check the Cables
Make sure the power, coaxial, DSL, and Ethernet cables are securely connected and undamaged. A loose cable may be the actual cause of the connection problem.
Disconnect Unnecessary Devices
This is not normally required, but temporarily disconnecting unnecessary Ethernet devices can simplify troubleshooting. Devices can be reconnected after the modem and router are fully online.
Avoid Interrupting an Update
Do not unplug or reset the modem if it appears to be installing a firmware update. Interrupting an update could cause startup or equipment problems.
Allow Enough Time for the Reset
After restarting the modem, give it approximately 5 to 10 minutes to reconnect before unplugging it again. A factory reset or firmware update may take longer. Repeatedly interrupting the startup sequence can delay recovery and make troubleshooting more difficult.
How to Reset a Modem Faster
You usually cannot make the modem’s internal startup sequence run faster. However, preparing the equipment correctly can prevent failed connection attempts, repeated resets, and other unnecessary delays.
Use the Correct Reset Method
Choose the least disruptive method that fits the problem:
Restart the modem through its app or administrative controls, if available.
Power-cycle it by unplugging the power cable when a restart option is unavailable.
Use the factory-reset button only when necessary, because this erases customized settings and may require additional setup.
Wait Before Plugging It Back In
When power-cycling the modem, unplug its power cable and wait approximately 30 to 60 seconds before reconnecting it. This gives the equipment time to shut down fully and clear temporary operating information.
Provider instructions vary, so follow the directions supplied with your modem or by your internet provider when they specify a different waiting period.
Check All Cable Connections
Before restoring power, make sure the power and service cables are firmly connected and undamaged. If you have a separate router, also check the Ethernet cable connecting it to the modem.
Avoid overtightening coaxial connectors or sharply bending fiber cables.
Restart the Router Afterward
If the modem and router are separate devices, allow the modem to come online first. Once the modem’s online light is solid, restart or reconnect the router if it has not recovered automatically.
A combined modem-router gateway does not require this separate step.
Allow the Modem to Finish Starting
Give the modem approximately 5 to 10 minutes to complete its startup sequence before trying another reset. Repeatedly disconnecting the power can interrupt synchronization or a firmware update and make recovery take longer.
Keep the Modem Cool
Place the modem in an open, well-ventilated area. Keep its vents free from dust and avoid placing it inside a closed cabinet, against another heat-producing device, or in direct sunlight.
Reconnect Devices After the Network Is Ready
You generally do not need to disconnect Wi-Fi devices during a normal restart. However, if you disconnected Ethernet equipment for troubleshooting, wait until the modem and router are fully online before reconnecting it.
This will not make the modem itself start faster, but it can make it easier to identify which part of the network is causing the problem.
Types of Internet Connections
The type of internet service you have affects how your equipment reconnects after a restart. Each connection uses different equipment and follows a different process for restoring service.
Cable Internet
Cable internet usually enters the home through a coaxial cable. After restarting, the modem searches for the provider’s signal, locks onto available downstream and upstream channels, receives any required configuration information, and reconnects to the network.
Signal interference, damaged coaxial cables, loose connectors, or unnecessary splitters can delay this process.
Fiber Internet
Fiber service commonly uses an optical network terminal, or ONT, rather than a traditional modem. The ONT converts the fiber-optic signal into a connection that a router can use.
After an interruption, the ONT must reestablish its optical connection before the router and Wi-Fi network can come back online. Fiber-optic cables are delicate and should not be sharply bent or repeatedly disconnected.
DSL Internet
DSL service delivers internet access over a telephone line. The DSL modem must synchronize with the provider’s equipment before internet access is restored.
Poor telephone wiring, line noise, damaged filters, or long distances from the provider’s equipment can slow synchronization or cause repeated disconnections.
Fixed Wireless Internet
Fixed wireless service receives an internet signal from a nearby provider tower or access point. The service may use an outdoor antenna connected to an indoor gateway or router.
After a restart, the equipment must detect the provider’s wireless signal and reestablish its connection. Distance, obstructions, severe weather, equipment alignment, and signal strength may affect reconnection.
Cellular Home Internet
Cellular home internet uses a gateway that connects to a mobile carrier’s network, much like a smartphone. The gateway must detect an available tower, register on the carrier’s network, and restore its internet and Wi-Fi connections.
Weak cellular coverage, tower congestion, indoor placement, or temporary carrier problems may extend the reconnection time.
Satellite Internet
Satellite internet uses a dish or terminal to communicate with satellites and the provider’s ground network. Restarting may involve reconnecting the satellite equipment, verifying the signal, and restoring communication with the provider’s network.
The process can take several minutes. Severe weather, an obstructed view of the sky, dish alignment, or provider network conditions may delay reconnection.
Regardless of connection type, the provider’s equipment should generally be allowed to finish reconnecting before a separate router is restarted. Exact startup times vary by provider, equipment model, signal conditions, and whether updates are being installed.
How Long Do Different Types of Modems Take to Reset?
Reset time varies according to the connection technology, equipment model, signal quality, and provider. The following estimates apply to a normal restart or power cycle—not initial installation or a factory reset.
| Equipment Type | Typical Restart and Reconnection Time | What Happens |
| Cable modem | 2–5 minutes | The modem starts, locks onto cable channels, and reconnects to the provider. |
| Fiber ONT or gateway | 2–5 minutes | The fiber equipment restores its optical connection before the router reconnects. |
| DSL modem | 3–5 minutes | The modem synchronizes with the provider over the telephone line and restores internet access. |
| 5G home internet gateway | 3–10 minutes | The gateway starts, connects to a cellular tower, registers with the carrier, and restores Wi-Fi. |
| Combination modem-router gateway | 5–10 minutes | The modem connection, routing functions, Wi-Fi network, and connected-device access must all restart. |
These are general estimates rather than guaranteed times.
If the equipment has not reconnected after 10 to 15 minutes, check its status lights, cables, provider outage information, and setup instructions. A firmware update, factory reset, weak signal, or service problem may require additional time.
Signs the Modem Has Finished Resetting
The modem’s indicator lights and the behavior of connected devices can help you determine when the reset is complete. Light colors and labels vary by model, so consult the equipment guide if you are uncertain.
The Power Light Is Solid
A solid power light generally indicates that the modem has completed its basic startup process. If the light remains off or continues flashing longer than expected, check the power cable and outlet.
The Online or Internet Light Is Solid
The light labeled Online, Internet, WAN, or with a globe symbol usually becomes solid once the modem has established a connection with the provider.
Some equipment uses a particular color to indicate a successful connection. The correct color depends on the modem or gateway model.
Connection Lights Appear Normal
Cable modems may have downstream and upstream lights that become solid after the modem locks onto the provider’s channels. DSL equipment may display a solid DSL or broadband light, while fiber equipment may show a normal optical or network status light.
Warning Lights Stop Flashing
Red, amber, or rapidly flashing status lights may indicate that the modem is still starting or has encountered a problem. However, some blinking is normal when the equipment is sending or receiving data. Check the manufacturer’s light guide before treating every flashing light as an error.
The Router Reconnects
If you use a separate router, its internet or WAN light should return to its normal status after the modem comes online. The Wi-Fi network name should also reappear on nearby devices.
Devices Reconnect to the Internet
Phones, computers, televisions, and other connected devices should begin reconnecting automatically. Some may need an additional minute or two after the modem and router finish restarting.
A Website or App Loads Successfully
The most reliable confirmation is to open a new website or another internet-dependent service on a connected device. A Wi-Fi symbol alone does not prove that internet service has returned because a device can connect to the router even when the modem remains offline.
Why a Modem Won’t Reconnect
If the modem remains offline after approximately 10 to 15 minutes, a service, signal, equipment, or activation problem may be preventing it from reconnecting.
Internet Provider Outage
An outage or provider maintenance can prevent the modem from establishing a connection. Check the provider’s app, website, outage map, or automated telephone service before resetting the equipment again.
Loose or Damaged Cable
A loose coaxial, DSL, Ethernet, or power cable can interrupt the connection. Make sure each cable is securely attached and inspect it for cuts, crushed sections, bent connectors, or other visible damage.
Avoid overtightening coaxial connectors or sharply bending a fiber-optic cable.
Incorrect Coaxial Outlet
In homes with multiple coaxial outlets, not every outlet is necessarily connected to the internet provider’s active line. A modem connected to an inactive or improperly wired outlet may turn on but never reach online status.
Weak or Missing Provider Signal
Damaged exterior wiring, excessive coaxial splitters, line interference, or another signal problem may prevent synchronization. These problems often require testing or repair by the internet provider.
Activation or Account Problem
A new, replacement, or factory-reset modem may need to be activated or registered to the account. The provider must have the correct equipment information, which may include the modem’s serial number or MAC address.
An unpaid or suspended account can also prevent service from being restored.
Interrupted Firmware Update
If power was removed during a firmware update, the modem may have difficulty completing its startup process. Allow additional time and follow the provider’s recovery instructions. Do not continue unplugging the equipment repeatedly.
Modem Failure
A modem that has overheated, suffered electrical damage, or developed an internal hardware problem may fail to reconnect. Warning lights, repeated restarts, unusual heat, or no power can indicate equipment trouble.
Do not open or attempt to repair the modem internally. Contact the provider or manufacturer if equipment failure is suspected.
Router or Wi-Fi Problem
If the modem’s online light is solid but devices still cannot access the internet, the modem may not be the problem. A separate router, Ethernet cable, or Wi-Fi setting may be preventing devices from getting online.
Restart the router after the modem is fully connected and check the Ethernet cable between them. Testing a wired connection, when supported and safe to do so, can help identify whether the problem is with the modem or router.
Factory-Reset Settings
A factory reset may restore the gateway’s original Wi-Fi name, password, and administrative settings. Devices using the previous Wi-Fi information will not reconnect until you reconfigure the network or connect them with the default credentials printed on the equipment label.
What to Do If Reset Doesn’t Work
If the modem does not reconnect after approximately 10 to 15 minutes, work through these steps before resetting it again.
1. Check for an Internet Outage
Use your provider’s mobile app, website, outage map, or telephone service to check for an outage. If the provider’s network is down, restarting the modem again will not restore service.
2. Inspect the Cables
Confirm that the power and internet service cables are securely connected. If you use a separate router, check the Ethernet cable between the modem and router.
Look for:
- Loose connectors
- Damaged or crushed cables
- Bent connector pins
- Unnecessary coaxial splitters
- A power adapter that is loose or unusually hot
Avoid overtightening coaxial connectors or sharply bending fiber-optic cables.
3. Examine the Status Lights
Check the power, downstream, upstream, online, DSL, broadband, optical, or internet lights, depending on the equipment. Compare them with the light guide supplied by the provider or manufacturer.
A red warning light or an online light that never becomes solid can help identify where the connection is failing.
4. Restart the Separate Router
If the modem appears to be online but Wi-Fi devices cannot access the internet, restart the router. Allow the modem to finish reconnecting first, and then restart or reconnect the router.
This step is unnecessary if you have a combined modem-router gateway that has already been restarted.
5. Test an Ethernet Connection
If your gateway has an available LAN port, connect a computer directly to it with a known-working Ethernet cable. This can help determine whether internet service is working and the problem is limited to Wi-Fi.
With a standalone modem and separate router, direct computer testing may require restarting the modem after switching the Ethernet cable. Follow your provider’s instructions, keep the computer’s firewall enabled, and reconnect the router after testing.
6. Contact the Internet Provider
If the modem remains offline, contact the provider before performing a factory reset. The provider may be able to:
- Confirm an outage
- Test the signal remotely
- Send a restart or activation signal
- Verify that the modem is registered correctly
- Identify an account problem
- Schedule a technician or replace faulty equipment
7. Perform a Factory Reset Only If Recommended
Use a factory reset only when the provider, manufacturer, or equipment instructions recommend it. This process erases customized settings, including the Wi-Fi name, password, parental controls, and other gateway preferences.
Afterward, the modem or gateway may need to be activated and configured again. Make sure you have the default login information and any necessary account credentials before proceeding.
Does Resetting Delete Settings?
Whether settings are deleted depends on the type of reset performed.
| Reset Type | Deletes Settings? | What Happens |
| Restart or reboot | No | The modem turns off and starts again while retaining its existing configuration. |
| Power cycle | No | Disconnecting power temporarily clears operating memory but normally preserves saved settings. |
| Factory reset | Yes | The modem or gateway returns to its default configuration. Customized Wi-Fi names, passwords, parental controls, port-forwarding rules, and other user-created settings may be erased. Reactivation or additional setup may also be required. |
Does Resetting a Modem Delete Its Settings?
Whether settings are deleted depends on whether you restart the modem or perform a factory reset.
Restart or Power Cycle
A normal restart does not erase saved settings. Unplugging the modem, waiting 30 to 60 seconds, and plugging it back in clears temporary operating information, but customized settings should remain intact.
These normally include:
- Wi-Fi network name and password
- Administrative login information
- Parental controls
- Guest network settings
- Port-forwarding rules
- Other customized network preferences
Factory Reset
A factory reset returns the modem or gateway to its original default settings. Customized settings may be erased, including:
- Custom Wi-Fi name and password
- Changed administrative password
- Guest networks
- Parental controls
- Port-forwarding rules
- Custom DNS or security settings
- Other user-created network preferences
After a factory reset, wireless devices may need to reconnect using the default Wi-Fi information printed on the equipment label. The modem or gateway may also require activation or setup through the provider’s app or website.
A factory reset does not necessarily remove the modem from the provider’s account records, but reactivation requirements vary. Record or back up important settings before proceeding.
| Reset Method | Deletes Customized Settings? | Usually Requires Reconfiguration? |
| Restart through an app or control panel | No | No |
| Power cycle by unplugging | No | No |
| Factory reset | Yes | Yes |
Does Resetting Change Your IP Address?
Resetting a modem may change your public IP address, but it is not guaranteed. The result depends on your internet provider, account type, equipment, and how the provider assigns addresses.
Dynamic Public IP Address
Most residential internet plans use dynamic public IP addresses. After a modem restart, the provider may assign the same address again, especially if the previous DHCP lease is still active. In other cases, the modem or gateway may receive a different address.
Leaving the modem unplugged longer still does not guarantee that the address will change.
Static Public IP Address
If your internet plan includes a static IP address, restarting or factory-resetting the modem normally will not change it. The provider has specifically assigned that address to the account or connection.
Private IP Addresses
A router assigns private IP addresses to devices inside the home, such as computers, phones, and televisions. These addresses may change when the router restarts and devices reconnect.
A factory reset can also restore the router’s default local network range, which may change the private addresses assigned to connected devices.
Cellular and Some Other Services
Cellular home internet and some providers use carrier-grade network address translation, or CGNAT. The public-facing address may be shared among multiple customers and can change independently of a modem restart.
Therefore, resetting a modem is not a reliable way to obtain a new public IP address. If a particular address is required for remote access, hosting, or another technical purpose, contact the internet provider about its IP-address options.
Can You Use Wi-Fi While the Modem Is Resetting?
You generally cannot use the internet through your home Wi-Fi while the modem is resetting. The modem must reconnect to the internet provider before online access can resume.
Combined Modem-Router Gateway
If your modem and Wi-Fi router are combined in one gateway, the Wi-Fi network may disappear temporarily while the equipment restarts. Devices should begin reconnecting after the gateway finishes starting.
Separate Modem and Router
If you use a separate router and leave it powered on, the Wi-Fi network may remain visible while the modem resets. Devices might still connect to the router, but they will not have internet access until the modem reconnects.
Some local-network functions may continue working, including:
- Accessing a network printer
- Transferring files between local devices
- Using network-attached storage
- Controlling certain locally managed smart-home devices
Whether these features remain available depends on the router and how the devices are configured.
Phones may automatically switch to cellular data while Wi-Fi internet service is unavailable. This can make it appear that the reset has finished even when the modem is still offline, so check the phone’s connection indicator before testing the home network.
Should You Reset the Router Too?
If you use a separate modem and router, restarting both devices can help restore the entire home network. Restart the modem first and the router second so each device reconnects in the correct order.
In this situation, “reset” usually means a normal restart or power cycle—not a factory reset.
Correct Restart Order
- Unplug the modem and router from power.
- Wait approximately 30 to 60 seconds.
- Plug the modem back in first.
- Wait until its online or internet light becomes solid. This commonly takes several minutes.
- Plug the router back in.
- Allow another minute or two for Wi-Fi and connected devices to return.
The modem must establish internet service before the router can distribute that connection to wired and wireless devices.
When Restarting the Router May Help
Restart the router if:
- The modem is online, but Wi-Fi is unavailable.
- Devices connect to Wi-Fi but cannot reach the internet.
- Only wireless devices are experiencing problems.
- The router’s internet or WAN light shows an error.
- The router does not reconnect automatically after the modem restarts.
Combined Modem-Router Gateway
If you have one device that provides both the internet connection and Wi-Fi, restarting that gateway restarts both functions. There is no separate router to restart.
Avoid pressing a router’s factory-reset button unless its manufacturer or your provider specifically recommends it. A factory reset can erase the Wi-Fi name, password, parental controls, guest networks, and other customized settings.
How Often Should You Reset a Modem?
A modem does not normally need to be reset on a regular schedule. Restart it when troubleshooting a connection problem or when your internet provider or equipment manufacturer recommends doing so.
A normal restart may help when:
- Internet service becomes unusually slow
- The modem loses its connection
- Websites and apps stop loading
- The modem’s status lights show a connection problem
- A separate router cannot reconnect
- The provider recommends restarting after an outage
There is generally no need to restart a properly functioning modem every day, week, or month. Many modern modems and gateways manage routine network maintenance and provider-issued updates automatically.
Frequent Resets May Indicate a Problem
If the modem must be restarted frequently to restore service, resetting is probably providing only a temporary solution. Possible causes include:
- Weak or unstable provider signal
- Loose or damaged cables
- Overheating
- Outdated or failing equipment
- Firmware problems
- Router malfunctions
- Provider network issues
Keep track of when the connection fails and what the modem’s lights display. Your provider may be able to test the signal, review connection history, or determine whether the equipment needs replacement.
A factory reset should be used much less frequently than a normal restart because it erases customized settings. Perform one only when the equipment instructions or internet provider recommends it.
Can Resetting Improve Internet Speed?
Restarting a modem can sometimes improve internet speed when a temporary equipment or connection problem is slowing service. However, it will not increase the maximum speed included with your internet plan.
A restart may help by:
- Clearing temporary modem or gateway errors
- Ending a stalled connection
- Allowing the modem to resynchronize with the provider
- Completing a pending firmware update
- Restoring communication between the modem and router
- Restarting Wi-Fi functions in a combined gateway
Any improvement may be temporary if an underlying signal, wiring, equipment, or provider problem remains.
What Resetting Cannot Fix
Restarting the modem will not permanently correct:
- An internet plan that is too slow for the household
- Provider network congestion
- Weak Wi-Fi coverage in distant rooms
- Damaged cables or poor signal levels
- Outdated or failing equipment
- Interference affecting a separate Wi-Fi router
- Slow websites or online services
- Device-specific performance problems
Test the Connection Before and After Restarting
Run a speed test before restarting and repeat it afterward using the same device, location, and connection type. For the most accurate comparison, use a wired Ethernet connection when possible and pause large downloads or streaming on other devices.
Speed-test results naturally fluctuate, so one improved result does not prove that the restart permanently fixed the problem.
A normal restart is usually sufficient for speed troubleshooting. A factory reset should not be necessary unless the provider or equipment manufacturer specifically recommends it.

Frequently Asked Questions
Does Unplugging a Modem Reset It?
Unplugging a modem performs a restart or power cycle. It clears temporary operating information but normally preserves saved settings.
It does not perform a factory reset. A factory reset requires using the modem’s reset button or selecting a restore-defaults option through its app or administrative controls.
Can Resetting Damage a Modem?
A normal restart should not damage a properly functioning modem. However, repeatedly disconnecting its power during startup can interrupt the reconnection process.
Avoid unplugging the modem while it appears to be installing a firmware update. Interrupting an update may cause software or startup problems. If the modem does not reconnect, allow at least 10 to 15 minutes before trying another troubleshooting step.
Why Do ISP Technicians Tell You to Reboot the Modem?
Internet provider technicians commonly recommend rebooting because it can clear temporary errors, restart stalled processes, and force the modem to establish a fresh connection with the provider’s network.
A reboot also gives the technician a clearer picture of whether the problem is temporary or caused by the signal, equipment, account, or provider network.
Can I Reset My Modem Remotely?
Some providers allow customers to restart a modem or gateway through a mobile app, website, or online account. Certain modems also include a restart option in their administrative controls.
Remote restarting may not work if the provider cannot communicate with the equipment. A factory reset usually requires physical access unless the modem’s controls specifically provide a restore-defaults option.
Will I Lose Wi-Fi While the Modem Resets?
If you have a combined modem-router gateway, its Wi-Fi network will usually disappear temporarily during the reset.
With a separate modem and router, the Wi-Fi network may remain visible, but devices will not have internet access until the modem reconnects. Wi-Fi service and connected devices should return automatically after startup unless a factory reset erased the customized network settings.
Should All Modem Lights Be Solid?
Not necessarily. The power and online or internet lights commonly become solid when the modem is ready, but Ethernet, Wi-Fi, or activity lights may continue blinking during normal data transmission.
Light names, colors, and patterns vary by model. Consult the modem’s light guide before assuming that a blinking light indicates a problem.
Why Does the Online Light Keep Blinking?
A blinking online light commonly means the modem is still trying to connect to the provider’s network. During startup, this may be normal for several minutes.
If it continues blinking for more than approximately 10 to 15 minutes, possible causes include:
- A provider outage
- A loose or damaged service cable
- Weak or missing signal
- An inactive coaxial outlet
- An activation or account problem
- A firmware or equipment failure
Check the cables and provider outage information. If the light never becomes solid, contact the internet provider for signal testing and activation assistance.
Quick Summary
Restarting a modem typically takes about 2 to 10 minutes, although the exact time depends on the equipment, internet connection type, signal quality, and provider. A factory reset may take longer because it erases customized settings and can require reactivation or additional setup.
Most modems reconnect to the provider automatically. Firmware updates, service outages, weak signals, damaged cables, activation problems, or failing equipment can delay or prevent reconnection.
If the modem remains offline after approximately 10 to 15 minutes, check the cables and status lights, review the provider’s outage information, and restart any separate router after the modem comes online. If these steps do not work, contact the internet provider before performing a factory reset.
