Quick answer
Start with the least destructive check, confirm the device state, and only then change settings. For this problem, the fastest route is usually: Confirm whether you pressed restart or factory reset. Check WAN cable placement. Find provider connection type before editing settings.
Before you start
- Confirm whether you pressed restart or factory reset.
- Check WAN cable placement.
- Find provider connection type before editing settings.
- Recreate Wi-Fi name and password after internet works.
Understand what reset changed
A restart keeps settings. A factory reset removes internet credentials, Wi-Fi name, password, port rules, and sometimes IPTV settings.
If the router returned to its default Wi-Fi name, it was factory reset and needs setup again.
Restore the WAN connection
Make sure the provider cable is in the WAN or Internet port. Then choose the provider connection type: DHCP, PPPoE, static IP, or another mode from your contract.
PPPoE needs a username and password from the provider. Guessing these values will not work.
Rebuild Wi-Fi after internet returns
Set a strong Wi-Fi password and use WPA2 or WPA3. Reusing the old network name can reconnect devices automatically, but only if the security mode matches.
Write down the admin password and provider settings before closing the router page.
Symptom checklist
| What you see | Most likely cause | First safe action |
|---|---|---|
| The device reacts, but the result is wrong | Wrong input, profile, mode, or account state | Confirm the visible setting before resetting anything |
| Nothing reacts at all | Power, cable, port, battery, or button issue | Test with a known good power source or cable |
| The problem comes back after reboot | Saved setting, weak signal, low storage, or failing accessory | Change one variable and write down what changed |
FAQ
- Can I undo a factory reset?
- Only if you exported a configuration backup earlier. Otherwise, the router must be configured again.
- Why do Wi-Fi bars show but websites fail?
- The local Wi-Fi network is working, but the router may not have an internet connection through the WAN port.
