Nokia Nseries :: Phone Won't Connect To Wifi?

I've had the 808 since the initial release in India, i.e since August 13. Got it replaced once for the purple tint issue. Though the replacement set has some issues with touchscreen response, but I've learned to live with it. And everything else was working fine, till about a week ago.But now my 808 cannot connect to Wifi, randomly (quite often, actually). If I enable the wifi and go to the Wifi main page, I can see my home network being detected and shown as "Known". I tap on it to connect, it says "Connecting" for about a second or even less than that and then says "Known" again. I've tried tapping on it many times, but it just doesn't connect. Tried different connections of wifi, i.e. joikuspot from my N8, cannot even connect to that. Disabling and re-enabling the Wifi don't work either.

To make Wifi work again, I have to reboot the phone every time the problem arises. It's really annoying, since I use a lot a Wifi.Sincerely,SabbyjHit the kudos button if I was of any help to you. And don't forget to mark the solution if I get one.
