[Resolved]  Micromax — Wifi Not Connected

I have recently purchased Micromax Canvas Nitro A310. Since the unboxing, I am facing wifi issue. For the first time after first switch on I was able to connect to wifi, but to my surprise after sometime i can't access internet though wifi is connected. I have no problem with wifi network as my another Samsung phone and laptop has no connection or access problem. Then i tried to connect the wifi after doing "forget password", but after I retype the password it shows "connecting", and sometimes "obtaining IP addresses", but never actually getting connected. For all I have to do for connection is to reboot the phone, and it automatically connects to wifi without even any need of typing the password. Please help resolve this issue. I have heard the customer support is really bad for Micromax.
