How to Factory Reset Your Router (and When You Shouldn't)

To factory reset a router, you press and hold the small recessed reset button on the back for about ten seconds while the router is powered on, then release it and wait for the router to reboot itself. That's the whole physical procedure. The part people get wrong isn't the button. It's everything around it: not writing down settings first, confusing a reset with a restart, and reaching for the reset button when the problem never needed one. This guide covers the right way to do it, what you'll lose, and the situations where a factory reset is exactly the wrong move.

First, the distinction that prevents most regret. A restart (pull the power, wait, plug back in) keeps all your settings and fixes temporary glitches. A factory reset erases everything and returns the router to the state it left the factory in: default network name, default password, all your customizations gone. Restart first, always. Reset only when a restart has already failed.

What a factory reset actually fixes (and what it doesn't)

A factory reset wipes the router's stored configuration. That makes it the right tool when the configuration itself is the problem:

• Settings got corrupted, and the router misbehaves in ways a restart doesn't cure
• You (or someone helpful) changed settings and can't remember what, and the network hasn't been right since
• You've forgotten the admin password and can't get into the router at all
• You bought the router second-hand and want a clean start
• You're troubleshooting chronic problems, like when a router keeps dropping WiFi even after restarts and firmware updates, and you need to rule out configuration before blaming hardware

What a reset will not fix: a slow line from your internet provider, weak signal in the far bedroom, an overloaded or dying router, or interference from the neighbors. Those live in physics and hardware, not settings. If your actual complaint is sluggish speed, start with our guide to figuring out whether your WiFi or your internet is the slow part, because a reset won't move the needle on either.

Before you press anything: the 5-minute inventory

A factory reset erases settings you may not remember creating. Spend five minutes collecting them and the whole experience becomes boring, which is the goal.

Write down or screenshot:

• Your WiFi network name and password. After the reset, the router broadcasts its factory-default network (printed on the sticker underneath). You'll want to recreate your old name and password so all your devices reconnect on their own.
• Your internet connection details, if any. Most home connections configure themselves automatically. But some providers require a username and password (common with certain DSL and fiber setups) or a specific connection type. Check the paperwork or email from your provider, or peek at the router's internet settings page before resetting. This is the one item that can leave you offline if you skip it.
• Any customizations you rely on. Port forwarding for a game server or camera, reserved addresses for a printer, parental control schedules, a guest network. Each takes a minute to note and a minute to recreate.
• The router's admin password. After reset it returns to the default on the sticker. If there's no sticker, look up the model's default before you begin, not after.

Do not factory reset a router that your internet provider configured with special settings unless you have those settings in hand or you're prepared to call support. Provider-supplied routers sometimes carry connection credentials that a reset erases, and without them the router will happily broadcast WiFi that leads nowhere.

How to factory reset your router, step by step

1. Confirm a restart hasn't already solved it. Unplug the router, wait 30 seconds, plug it in, wait five minutes, and test. If the problem is gone, stop here and keep your settings. A reset you didn't need is just unpaid IT work.

2. Complete the settings inventory above. Network name, WiFi password, provider credentials if any, customizations, default admin password. Screenshots of the router's settings pages are the fastest method.

3. Find the reset button. It's on the back or bottom: a small hole labeled Reset, sized so you can't press it by accident. You'll need a paperclip, SIM tool, or toothpick. On some models it's a normal small button rather than a recessed one.

4. With the router powered on, press and hold the button for about 10 seconds. Hold until the lights change behavior (they typically all blink, go out, or change color). A short press often just restarts the router, which is why holding matters. Some models want up to 15 seconds; holding a little long does no harm.

5. Release and let the router reboot fully. This takes a few minutes. Don't pull the power during this stage; interrupting a router mid-reset is one of the few ways to genuinely hurt it. Wait until the lights settle into a steady normal pattern.

6. Connect using the factory defaults. On the sticker under the router you'll find the default WiFi name and password. Connect a phone or laptop to that network, then log in to the admin page with the default admin credentials from the same sticker.

7. Run the setup and restore your settings. Most routers greet you with a setup wizard. Recreate your old WiFi name and password exactly as before, and every device in the house reconnects automatically, no closet full of gadgets to re-pair. Enter provider credentials if your connection needs them, then re-add your noted customizations.

8. Change the admin password and update the firmware. While you're logged in: set a new admin password (not the WiFi password, the one for the settings page) and check for a firmware update. A reset is the perfect moment, since you're already in there and the configuration is clean.

Reset methods compared

There's more than one way to do this, and they're not equal.

If your router's admin page or app offers a configuration backup (an export-settings option), take one before resetting. Restoring a backup after a reset defeats the purpose when the configuration itself is corrupt, but it's a useful reference for reading back what your settings were.

When you shouldn't factory reset

The reset button has a fan club it doesn't deserve. Skip the reset when:

• You haven't restarted yet. A restart fixes the majority of router weirdness and costs nothing. The reset should never be the first move.
• The problem is speed or coverage. Slow internet, weak signal upstairs, dead zones by the terrace: these are line, placement, or hardware issues. A reset returns you to the exact same physics with extra chores.
• You don't have your provider credentials and your connection needs them. Get them first. An evening without internet because of a preventable missing password is a self-inflicted wound.
• The router is mid-update. If the firmware is updating, touch nothing until it finishes. Interrupting an update can leave the router genuinely dead rather than misconfigured.
• The router is old and failing anyway. If it's years past its prime, runs hot, and drops connections under load, a reset just delays the real decision. See our guide to choosing a router that fits your home before sinking another weekend into the old one.

One case where you absolutely should reset, though: before selling, returning, or recycling a router. Your WiFi password, admin password, and network configuration are stored on it, and a ten-second reset is cheap insurance against handing them to a stranger.

Frequently asked questions

How long do I hold the reset button on a router?

About 10 seconds, with the router powered on, until the lights visibly change behavior. Some models require up to 15 seconds. A tap or short press usually only reboots the router, so if nothing changed, hold longer.

Will a factory reset delete my WiFi password?

Yes. The reset erases your custom network name and password and restores the factory defaults printed on the router's sticker. If you recreate your old name and password during setup, all your devices reconnect automatically, which is why you write them down first.

Does a factory reset make my internet faster?

Not by itself. A reset fixes problems caused by corrupted or wrong settings, and if such a misconfiguration was throttling you, speed can improve. But it does nothing for a slow provider line, weak coverage, or aging hardware, which cause most speed complaints.

What's the difference between restarting and resetting a router?

A restart powers the router off and on and keeps every setting; it fixes temporary glitches. A factory reset erases all settings and returns the router to its out-of-the-box state. Restart for hiccups, reset for corruption, forgotten passwords, or a clean start.

Do I need to reset my router before selling it?

Yes, always. The router stores your WiFi password, admin password, and network details, and a factory reset is the only practical way to wipe them. Hold the reset button for about 10 seconds, let it reboot, and it's safe to hand over.

My router won't work after the reset. What now?

Wait the full boot time (several minutes), then confirm you're connecting to the factory-default network from the sticker, not your old network name, which no longer exists. If WiFi works but internet doesn't, your connection likely needs provider credentials re-entered. When in doubt, power-cycle the modem too, and call your provider with your router model at hand.

The 30-minute rule

Here's a fair way to decide your next move after a reset. Set up the router cleanly, then live with it for a few days. If the original problem is gone, the configuration was the villain and you're done. If the problem survives a factory reset, you have learned something valuable: it was never the settings. That means hardware, placement, interference, or your provider's line, and no amount of further resetting will change the verdict. Spend your next 30 minutes on those suspects instead, and if the router is the one failing, replace it without guilt. It served, it got a clean reset, and it still couldn't. That's as honest as hardware diagnosis gets.
