I have Digisol router in my home. My phone was connected to it for a time, but then suddenly it started showing no internet. So I tried to reconnect by Forgot password. But since then I am facing the *Authentication Problem** every time I tried to connect. Some points:
- It is connected to a PC by LAN and two phones by WiFi. It is working fine in all of them.
- I have tried to clear Google Services Framework cache and restart. Still nothing happened.
- Also I tried to turn Airplane mode on and off.
