I have bought Galaxy S2 just two months back. My wifi was working fine until one day it stopped working. When I switch on my wifi, it just scan for the network and then gets off. My other devices are working fine with the router. The same problem exists even after doing a factory setting for the phone and reseting the wifi router at my home.
There are few things worth noticing about the problem:
1) My PC is detecting so many wireless networks around here but my phone wifi detects none because it seems to me that the wifi is not even getting started in my phone ... no wifi notification symbol.
2) On starting other wifi related setting like "wifi direct", my phone hangs and it shows a dialogue to force close it.
3) Some times the phone shows "Error" in the wifi settings (pic in the attachment)
4) In the advance wifi setting, the phone is showing MAC address as unavailable.
So many people is facing the same problem. Please follow the link below where the thread initiated by me is responded by so many people. There is serious problem in this phone with the wifi.
Please let me know what to do because I have already tried everything. My phone detect no wifi network anywhere.

From the thread it seems that even giving the phone to the Samsung service center does not solve the problem. I am a bit worried now
Please suggest some solution for the problem.
