How to Reset a Router Without Losing Your Settings
Short answer
Unplug the router for 60 seconds and plug it back in — that is a power cycle, it fixes most faults and changes nothing. Do not press the recessed reset button unless you intend to erase everything: it restores factory defaults and wipes your Wi-Fi name, password, DNS and port forwarding. If you need a true reset, export a configuration backup from the admin page first.

These two operations get described with the same word and they have completely different consequences. One is safe, takes two minutes and solves the majority of router faults. The other erases your configuration and leaves you reconnecting every device in the house.
Do not press the recessed reset button as a troubleshooting step. It is not a stronger restart. It restores factory defaults, which means your Wi-Fi name and password revert to whatever is printed on the label, and every custom setting you have ever applied is gone.
The difference, plainly
| Power cycle | Factory reset | |
|---|---|---|
| How | Unplug the power cable for 60 seconds | Hold the recessed button ~10 seconds |
| Wi-Fi name and password | Kept | Erased, reverts to label |
| DNS, port forwarding, static leases | Kept | Erased |
| Guest network, parental controls | Kept | Erased |
| Admin password | Kept | Reverts to factory default |
| Devices need reconnecting | No | Every one of them |
| Fixes | Most intermittent faults | Corrupted config, forgotten admin password |
The power cycle works because routers are small computers with limited memory and firmware that is rarely as well tested as it should be. Over weeks of uptime, NAT tables fill, DHCP leases tangle and memory leaks accumulate. Cutting power clears all of it.
Do this first
Unplug the power cable. Not the reset button, not a switch on the wall if you are not sure what it controls — the power cable from the back of the router.
Wait 60 seconds. This matters more than it sounds: capacitors inside hold charge for several seconds, and some routers retain enough state through a quick off-and-on that the restart achieves nothing. Sixty seconds is comfortably sufficient.
Plug it back in and wait 2–3 minutes for the lights to settle.
If your modem is a separate box, the order matters, because the router requests a connection from the modem and needs it ready first:
- Unplug the modem.
- Unplug the router.
- Wait 60 seconds.
- Plug in the modem, wait until its lights are steady (2–3 minutes).
- Plug in the router, wait another 2 minutes.
Doing this in the wrong order is why “I restarted it and it did not help” sometimes means “I restarted it incorrectly”.
The soft reboot from the admin page
Most routers offer a restart option in the admin interface, usually under a system, administration or tools section. It performs a clean software restart and preserves everything, the same as a power cycle.
Occasionally it is less effective than pulling the cable, because the hardware never fully loses power. If a soft reboot did not help, try the physical version before escalating.
Some routers also offer a scheduled restart — a nightly or weekly reboot at a fixed time. On a router that develops faults after a week of uptime, this is a legitimate workaround, though it is worth checking for a firmware update first since that is usually the underlying cause.
Back up before any real reset
If you have decided a factory reset is genuinely necessary, spend five minutes on this first.
Export the configuration. Look in the administration, system tools or
management section for Backup, Export settings or Save configuration.
It produces a file, often with a .cfg, .bin or .dat extension.
Be clear about what that file is worth. It restores onto the same router model, usually on the same firmware version, and is frequently rejected after a firmware upgrade. It will not transfer to a different router. Treat it as a convenience rather than insurance.
Photograph or write down the things that actually matter, because these survive any firmware mismatch:
- Wi-Fi name and password, for each band if they are separate
- The admin password, if it is not the factory one
- Custom DNS servers
- Port forwarding rules, with ports and target addresses
- Static DHCP reservations
- Guest network name and password
- Parental control schedules
- Your provider’s connection credentials, on a DSL line
Save your saved Wi-Fi passwords from a PC if you are about to run a Windows
network reset alongside this —

covers the netsh export that saves them all at once.
When a factory reset is the right answer
It is justified in three situations and no others:
- You cannot log in. Someone changed the admin password and nobody remembers it. A reset is the only route back in, and the factory credentials on the label will work afterwards.
- The configuration is genuinely corrupted. Settings that will not save, pages that error out, behaviour that persists through power cycles and firmware updates.
- You are giving the router away or returning it. A reset removes your Wi-Fi credentials, device history and any account linkage.
Everything else — slow speeds, dropouts, a device that will not connect, poor coverage — has a cause a reset does not address. Those are bands, interference, firmware and hardware age. Resetting trades your entire configuration for a very small chance of improvement.
How to do it, if you must
The reset button is recessed and needs a paperclip or SIM tool. It is usually on the back or base, often labelled Reset or RST.
With the router powered on, hold it for about 10 seconds until the lights flash or go out together. Release and wait 3–5 minutes for the router to rebuild its default configuration and come back up.
Then reconnect using the Wi-Fi name and password on the label, and work back through the setup — setting up a router from scratch covers the sequence and the settings worth changing before you finish.
A detail worth knowing: a reset also restores the admin password to the factory default, which is published for every model. Change it immediately afterwards rather than at some point later.
The resets that are not router resets
Three other operations get described as “resetting the network” and have different blast radii. Knowing which one an instruction means saves a lot of unnecessary work.
- Windows network reset — Settings → Network & internet → Advanced network settings → Network reset. Removes every saved Wi-Fi network, VPN configuration and adapter setting on that PC, then restarts after about five minutes. Nothing on the router changes. Export your saved passwords first.
- Phone network settings reset — on iPhone, Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings; on Android, Settings → System → Reset options → Reset Wi-Fi, mobile and Bluetooth. Clears saved networks and Bluetooth pairings on that handset only.
- Modem restart — power cycling the provider’s box. Safe, and distinct from the router restart when the two are separate devices.
If the fault affects one device, those are the resets to consider, and the router does not need touching at all.
Realistic expectations
A power cycle resolves the majority of intermittent router faults, and if the same fault returns within days, the router is telling you something — usually that it needs a firmware update, or that it is old enough to be replaced.
A factory reset fixes the small set of problems that are genuinely configuration corruption. It does not make a router faster, extend its range or improve its Wi-Fi, and the afternoon spent re-pairing smart home devices is a real cost that people consistently underestimate.
