Show stop conditions
- The phone becomes unusually hot or restarts repeatedly
- The issue began after physical or liquid damage
Likely causes
- The saved Wi-Fi password is outdated
- The router has stopped assigning addresses
- Private DNS, VPN, or randomized MAC settings conflict with the network
- The phone network settings are corrupted
Quick checks, in order
Forget and rejoin the network
Remove the saved network, then enter the password again.
Restart both devices
Restart the phone and power-cycle the router for 30 seconds.
Disable VPN and private DNS temporarily
Test without traffic-filtering or custom DNS services.
Try another Wi-Fi network
This separates a phone problem from a router or provider problem.
Which message do you see?
Forget the network, verify the password, and check whether the router uses a compatible security mode.
The Wi-Fi link works, but the router or provider is not reaching the internet. Test another device on the same network.
Move closer, restart the router, and verify that the router broadcasts a compatible 2.4 GHz or 5 GHz network.
Stop and get qualified help when
- The phone becomes unusually hot or restarts repeatedly

Frequently asked questions
Will resetting network settings delete photos?
No. It normally removes saved Wi-Fi, Bluetooth, and mobile network settings, not personal files.
Why does Wi-Fi work on other devices?
That usually points to a saved setting, software conflict, or hardware problem on the phone.
