How to Reset a Router (and When You Should)

Most home internet trouble ends with someone saying "have you tried turning it off and on again?" That advice is fine, but the word reset covers two very different jobs. One is a harmless restart that takes a couple of minutes. The other wipes every setting you or your provider ever made. Knowing which is which saves a lot of evening.

Restart or factory reset: the short version

The rule of thumb is simple: always try a restart first. A factory reset is the last item on the list, not the first.

How to restart a router properly

1. Unplug the power cable from the router, not just the button on the front. If you have a separate modem, unplug that as well.
2. Wait about thirty seconds. This gives the hardware time to fully power down rather than flicker.
3. Plug the modem back in first, if you have one, and wait until its lights settle.
4. Plug the router back in and give it a few minutes. The lights usually blink through a start-up sequence before they steady.
5. Test from one device before declaring victory. Open a page you have not visited today so you are not looking at a cached copy.

Many routers also have a restart option in their app or admin page. It does the same job and saves you crawling behind the TV cabinet.

When a factory reset makes sense

A full reset is the right call in a handful of situations:

• You have forgotten the admin password and cannot get into the settings at all.
• Someone changed a setting, nobody remembers which one, and the network has misbehaved ever since.
• Restarts no longer help and the problem keeps coming back within hours.
• A firmware update was interrupted and the router behaves oddly afterwards.
• You are selling, returning or giving the router away and want your details off it.

If the internet is down for the whole street, a reset will not help. Check your provider's status page or call them before you wipe anything.

Before you press the reset button

This is the part people skip, and the part that turns a five-minute job into a long night. Take notes first:

• Your current Wi-Fi name and password. Reusing them means phones, TVs and speakers reconnect without fuss.
• Any login details from your provider. Some connections need a username and password entered on the router. These are usually on a welcome letter or in your account online.
• Special settings such as port forwarding for a games console, a guest network or parental controls.
• The default login label on the underside of the router. Photograph it.

How to do a factory reset

1. Leave the router switched on.
2. Find the small recessed Reset hole, usually on the back.
3. Press and hold it with a straightened paper clip or a SIM tool. Most models want somewhere between ten and thirty seconds; the manual or the maker's support page will tell you the exact time.
4. Release when the lights flash or change pattern, then leave it alone while it restarts.
5. Connect to the default network printed on the label and open the setup app or admin page.
6. Set a new admin password first, then restore your Wi-Fi name, password and any provider details from your notes.

If your provider supplied the router, it may set itself up automatically once it reconnects. Give it time before you start changing things by hand.

After the reset

Check for a firmware update while you are in the settings. Then reconnect the devices that matter most: work laptop, TV, anything that streams. If you watch through an internet TV box, it may need its network chosen again, which is a good moment to look at how the box connects in the first place. Our piece on IPTV and cable covers why a steady connection matters more for one than the other.

Signs the router is the wrong suspect

Sometimes the router is fine and the problem sits elsewhere. If only one device struggles, restart that device instead. If the signal is strong next to the router but weak two rooms away, a reset will not change the walls. That is a placement and coverage question, which we cover in how to boost your Wi-Fi signal at home.

A tidy checklist to keep

• Restart before you reset.
• Write down names, passwords and provider details before any factory reset.
• Change the default admin password straight away afterwards.
• Keep a note of the setup somewhere you will find it next time, such as inside a kitchen drawer or a password manager.

Routers are not complicated, but they are unforgiving of guesswork. A two-minute restart fixes most bad evenings. Save the reset for the rare night when nothing else works, and go in with your notes ready.
