Restart or reset? Know the difference

People often say "reset" when they mean "restart", and some apps blur the two. They are very different:

  • Restart (reboot, power cycle): turns the router off and on. Keeps every setting. Safe to do anytime.
  • Factory reset: wipes your configuration and returns the device to its out-of-the-box state. Cannot be undone.

For slow speeds, dropped Wi-Fi or a router that seems stuck, restart first: unplug the power (or use the power switch if there is one), wait about 30 seconds, plug it back in and give it a few minutes. If you have a separate modem and router, restart the modem first, wait for it to come online, then restart the router.

When a factory reset makes sense

  • You forgot the admin password you set and cannot log in. See the forgot router password guide for alternatives first.
  • The router is unresponsive: the admin page will not load even over Ethernet, and restarting does not help.
  • You changed too many settings and cannot work out how to undo them.
  • You suspect tampering: unknown devices, DNS servers you did not set, or port forwarding rules you did not create.
  • You are selling, giving away or returning the router.
  • Your ISP's support asks you to as part of troubleshooting.

A reset is not the right tool for slow Wi-Fi or poor coverage (see weak Wi-Fi signal and how to speed up Wi-Fi) or for a short outage after a power cut, which a restart handles.

Factory reset with the reset button

This works even when you cannot log in, and it is the method most manuals describe.

1. Find the reset button

Look on the back or bottom for a small hole or button labeled Reset (sometimes RST or a circular-arrow icon). It is usually recessed so it cannot be pressed by accident. On some routers the reset function is combined with the WPS button; on those, a short press does something different from a long hold, so check the manual.

2. Use a thin, rigid tool

An unfolded paper clip or a SIM ejector tool is ideal. Avoid toothpicks or pencil leads, which can snap off inside.

3. Press and hold with the router on

The router must be powered on: the reset is handled by its software, which needs to be running to notice the long press. Press and hold the button continuously. Typical hold times are around 10 seconds for many consumer routers and up to 30 seconds for some gateways. If you are not sure, hold for 30 seconds; holding longer than necessary does no harm on most devices.

A short press is the most common mistake. If you let go after two or three seconds, the router may just restart, and your old settings, including the password you forgot, will still be there.

4. Watch the lights

While you hold the button, the lights usually do something distinctive: they all turn off and back on, flash together, or change color. That signals the reset has been accepted. Release the button.

5. Wait for the full restart

Give the router several minutes before trying to connect. On ISP gateways, the internet light may take longer to turn solid while the gateway reconnects to the provider's network and downloads its configuration. Do not unplug it during this time.

Factory reset from the admin page or app

If you can still log in, a software reset does the same job without touching the device. Typical locations (exact names depend on model and firmware):

  • System → Factory Reset, Administration → Restore Defaults or Maintenance → Backup & Restore in most router web interfaces
  • Advanced → Administration → Backup Settings or similar on Netgear routers
  • Administration → Restore/Save/Upload Setting on ASUS routers
  • Device or gateway settings inside the TP-Link Deco, eero, Google Home, Orbi and Linksys apps

Confirm the prompt and the router restarts with factory settings. From then on, the process is identical to a button reset.

Resetting US ISP gateways

Provider-supplied gateways reset the same way as any router, with a few points worth knowing. Before you reset, consider whether a restart from the provider's app would solve the problem: it is less disruptive and is often the first thing support will ask you to try.

  • Xfinity: the Xfinity app can restart the gateway remotely. A factory reset is done with the recessed reset button or from the Admin Tool at 10.0.0.1. Afterward your Wi-Fi returns to the label name and password. See the Xfinity guide.
  • Spectrum: My Spectrum lets you restart equipment. If you reset a Spectrum Wi-Fi router, you may need to reactivate or re-add it in the app. See the Spectrum guide.
  • AT&T: the gateway's reset button restores factory settings, including the Wi-Fi network on the label. The Device Access Code on the label stays the same. See the AT&T guide.
  • Verizon Fios: after a reset the router returns to the network name, Wi-Fi password and admin password printed on its label. See the Verizon Fios guide.
  • Cox: Panoramic Wifi gateways can be restarted from Cox's app; a factory reset uses the reset button. See the Cox guide.
  • T-Mobile Home Internet: the T-Mobile Internet app offers restart and reset options for the gateway. See the T-Mobile guide.

If the internet light does not go solid after a reasonable wait, contact your provider: they can check from their side whether the gateway has re-registered on the network.

What to do after the reset

1. Confirm the connection is back

Check that the internet or WAN light is solid (the exact color convention varies by brand). On a router you own behind a separate modem, confirm the modem is online too. If your service uses PPPoE, enter the credentials from your provider in the router's Internet/WAN settings.

2. Log in with the factory credentials

Connect to the default Wi-Fi network from the label, or plug in with Ethernet. Then open the admin page (see how to log in to your router) and use the label credentials. Many newer routers launch a setup wizard on first login.

3. Set a new admin password immediately

Before anything else, replace the default admin password with a strong, unique one and save it in a password manager. See default router passwords for why this matters.

4. Restore your Wi-Fi name and password

If you set the same network name and password you used before the reset, most of your devices will reconnect on their own, which saves a lot of time with smart home gear. Otherwise, follow how to change your Wi-Fi password and reconnect each device.

5. Rebuild the rest of your settings

Port forwarding (see the port forwarding guide), custom DNS (see router DNS settings), DHCP reservations, guest network and parental controls all need to be set up again, or imported from a backup file if you made one.

Frequently asked questions

What is the difference between restarting and resetting a router?

A restart (also called a reboot or power cycle) turns the router off and on again. It keeps all of your settings and fixes many temporary glitches. A factory reset erases your settings and returns the router to the state it left the factory in. Always try a restart first: unplug the power for about 30 seconds, plug it back in, and wait a few minutes. Some apps label a restart as "Reset" or "Restart gateway", so read the confirmation text carefully before tapping.

Will a factory reset cancel or break my internet service?

No. Your service account is not affected. On an ISP gateway (Xfinity, AT&T, Verizon, Cox, Spectrum, T-Mobile), the device is typically recognized by the provider's network and gets its connection settings automatically after the reset, though it may take a while. On a router you own, connected to a separate modem or fiber ONT, most US connections use automatic IP (DHCP), so internet usually returns once the router is back up. If your connection uses PPPoE (some DSL and fiber services do), you will need to re-enter the PPPoE username and password from your provider.

How long does a router reset take?

Holding the button takes 10 to 30 seconds depending on the model. The restart afterward usually takes a few minutes. ISP gateways can take longer because they may check for firmware updates and pull their configuration from the provider. Budget extra time for the part that actually takes longest: setting the Wi-Fi name and password again and reconnecting every device.

Can I reset my router from the admin page or app instead of the button?

Yes, if you can still log in. Most routers have a factory reset option in the web interface, typically under System, Administration, Maintenance or Backup & Restore. Many ISP and mesh apps also offer a factory reset, usually inside the device or gateway settings. If you have forgotten the admin password, the software method is not available and the physical button is the way in.

What exactly gets erased by a factory reset?

Everything you configured: (1) Wi-Fi network name and password (back to the label values); (2) admin password; (3) port forwarding rules; (4) custom DNS settings; (5) DHCP reservations and static IP assignments; (6) guest network; (7) parental controls and device schedules; (8) firewall, QoS and VPN settings. What stays: the firmware version currently installed, and on ISP gateways, the provider's connection settings, which are restored automatically.

Should I back up my settings before resetting?

If you are resetting for convenience and still have access, yes: many routers can export a configuration file under Backup & Restore, which you can import afterward. Restore only to the same model, and preferably the same firmware. Do not restore a backup if you are resetting because you suspect someone tampered with the router; in that case you want to start clean. App-based mesh systems and many ISP gateways do not offer a downloadable backup, so take screenshots or notes of important settings instead.

Should I reset my router before returning it to my ISP or selling it?

Generally, yes. A factory reset removes your Wi-Fi name, passwords and other personal settings before the device leaves your home. For provider-owned equipment, check your ISP's return instructions as well, since some providers ask you to return gateways in a specific way. For mesh systems such as eero or Google Nest Wifi, also remove the device from your account in the app so the next owner can set it up.

Does a factory reset remove the router firmware or install updates?

No. The reset clears your configuration, not the firmware. The router keeps whatever firmware version it had. Firmware updates are a separate process from the admin page or app. Many current routers and almost all ISP gateways update automatically. If you update manually, only use firmware from the manufacturer for your exact model and hardware version, and do not unplug the router during the update.
