Default HELP! Wifi stop working for samsung galaxy S2

Hi,

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.

Link where you find people facing the same problem:

http://forum.xda-developers.com/show....php?t=1335738

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.
Thanks.

I'm having no problems with my Wi-Fi, did a full reset with recovery when I debranded my SGS2 too.
The only time I've seen error for Wi-Fi like that on an Android device was when flashing a kernel on my Sony Ericsson Xperia X10i, this was because the Wi-Fi system files were missing but easily fixed by flashing them with xRecovery.
Have you tried updating the phone with Kies, it might be an option?

Sorry I can't help more!


EDIT- Is your SGS2 rooted? Mine is so I could copy the Wi-Fi system files and put them in my Dropbox and post a link?!?

Hi JayJ,

Thanks allot for the the response, really appreciate it and sorry for coming back late since I was out of town and had no internet access. It will be great help if you share the wifi related system files. My phone is not rooted now but I will root it. Is there anyway I can unroot my phone again so that my warranty remains?

Details:
Version - 2.3.3
Baseband version - I9100DDKE4
Kernel Version - 2.6.35.7-I9100XWKF3
Build Number - GINGERBREAD.XWKF3

Thanks,
Rishi

Toady only I tried at a mall...it worked fine and scanned all the networks arround...but since I have messed up with the wireless setting in the phone to was not able to open any web page...will try again there. But at home I am still facing the same issue. Thus the conclusion is either my router or the neighbors router is creating some problem. Or there may be one more possibility...the handset don't know what to do when there is no network arround and you try to switch on the wifi in your phone so it keeps on scanning. I am telling this because if my router or the neighbors router was the problem then why the problem persists when I tried opening the phone wifi at the place where there is no network. At home it might not be able to detect the wifi so keeps on scanning. Not detecting the network may be the reason with the netgear router or the wireless channel. Do you also have a netgear router?? I would suggest to try at some public places like some hotel or mall before you try anything with the phone. Please post if you find any solution. In the mean while I am also looking to find some solution. Will update you if found any. Thanks.
