wi fi - 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:

1. When entered the password, proxy etc: Saved, secured with WPA2



2. When tapped on connect: Authenticating...


3. 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.

Answer

I solved the problem by replacing the default wifi driver that comes with windows with the one downloaded from manufacturer website.
