Authentication problem while connecting to WiFi hot spot! I just unboxed my androidOne device (Micromax Canvas A1) and while connnecting to my WiFi hotspot it loops through:


When entered the password, proxy etc: Saved, secured with WPA2
When tapped on connect: Authenticating...
and then: Authentication Problem


Note that my room-mates (and even I, with my other phone,) can use the hot spot.

Is this an indication of problem with device? 

I tried: 

1. Forgetting access points and resetting passwords.
2. restarting my phone several times
3. restarting my hotspot several times
4. factory resetting the phone once


nothing worked.
I faced a similar problem since months on my Android phone ( Jellybean and Kitkat ). The problem some how used to come and go and recently it was the same again. After spending a couple of hours with many hit and try things with my phone and router I finally found a good article which solved this problem ( at least ) for me.

Solution


  Settings, Apps, All, Clear data in google services framework and restart

Read the above article as it has a lot of other methods also but in my case none of the others worked. Check if anyone works in your case.

Before following above steps I would kindly request to go through the article about what things can be impacted when Google Services Framework data is cleared.

In my case I have tried almost everything and nothing worked. Clearing the google services framework data was the last option left and I gave it a try. My case - it worked well and I did not even have to restart the phone, I was able to connect the WiFi.

Hope it helps.
