Know which password you have lost before you touch the reset button. A factory reset wipes your entire configuration, and it is unnecessary for most situations.
The two passwords people confuse
| Admin password | WiFi password | |
|---|---|---|
| What it does | Opens the router settings | Lets devices join the network |
| Where you enter it | Browser, at the router address | On phones, laptops, TVs |
| If forgotten | Factory reset usually required | Change it from inside the settings |
| Effect of changing it | Nothing disconnects | Every device must reconnect |
If you can still log into the router, you never need a factory reset. Change the WiFi key from inside the settings and nothing else is disturbed.
Changing the WiFi password the easy way
- Connect to the network on any device that still remembers it.
- Open a browser and go to the router address, commonly 192.168.1.1 or 192.168.0.1.
- Log in with the admin credentials.
- Find Wireless or WiFi settings and change the key.
- Save. Every device will disconnect and need the new password.
The factory reset, and what it costs
If the admin password is lost, a factory reset is normally the only route. Hold the recessed reset button with a paperclip for ten to thirty seconds while the router is powered on, until the lights cycle.
What you lose is worth listing, because people underestimate it:
- WiFi network name and password, so every device in the house must be reconnected.
- Port forwarding rules, which breaks games, cameras and remote access.
- Static IP assignments for printers and servers.
- Parental controls and device schedules.
- Custom DNS settings.
- Any ISP-specific configuration, which on some connections must be re-entered before internet works at all.
Before you reset, take five minutes
Photograph the current settings pages if you can still see them, and check whether your router supports exporting a configuration backup. Note the ISP connection type and any credentials it needs. On some connections, particularly those requiring a username and password for authentication, a reset leaves you offline until those are re-entered, and finding them afterwards is considerably harder than noting them beforehand.
