[Solved-3 Solutions] WIFI - Connection Timed Out Error on Android
Wi-Fi works properly on all other devices but not with a particular phone. Some apps like WhatsApp and some websites work whereas apps like Facebook and Google Play store display an error.
Reboot your device and retry if the problem still persists.
Even though your Wi-Fi works with all your other devices, restart your modem and see if the problem persists.
Make sure you are not using any proxy server. If you’re using, then remove it and retry.
