the galaxy s2 of my officemate is experiencing the said problem, whenever i try to open wifi, it will open and scan for almost 2 minutes and then wifi will turn off. several attempts will lead to FC of wifi and you have to restart the phone so you can try to open wifi again. i also noticed that when i turn the phone off, it will not turn on again unless i press vloume down + home + power button.
Tell your officemate to flash a decent ROM and don't touch the phone if he/she doesn't know what is doing...
I bet he/she has a custom kernel or has touched something it shouldn't be touched...
Have to agree that this sounds like a bad ROM and I would suggest you go to this thread http://forum.xda-developers.com/showthread.php?t=1075278 and use Odin to revert back to an official ROM which should fix your problem.
Hope this helps
sorry i forgot to mention that the phone is not rooted and just using a stock/official rom
Yesterday,after I flashed stock ICS rom through odin, I noticed that i can't connect to any kind of wifi connection, even wifi sharing from other devices! it says just "obtaining ip address" and nothing. stuck like that forever. What?

My problem was unable to turn on wifi, wifi stuck at the stage of turning on.... and forever like that cant off and on.
Most probably is hardware problem coz i have tried many ways to solve including flash back to stock rom,change modem,change kernel and etc.
good luck for you,hope you are not the same problem with me.

Wifi is kernel-related.
So, try to flash another kernel to test.
Or if you don't want to flash another kernel, check in menu Settings > wifi > (menu button) Advanced > Use static ip.
Try to enabled and connect.
Then disable and try to connect.
If that does not help, try to wipe cache (and Dalvik cache) in recovery mode.
Press Volume UP + Home + Power buttons as long as the recovery menu appears, then select wipe cache and reboot the phone.
P.S.: Check the configuration of your wifi router / WLAN access point, that is allows your phone to connect.
ok so i did everything again just to be sure and... my mistake! the problem starts not after the rom flashing but after cf root! have i done something wrong maybe?
I would say look for a custom rom that is already pre-rooted so then it should have all bugs to do with wifi removed.
I used to have a problem with the wifi myself which caused problems when turning it into a wireless hot spot and then wouldn't turn back off again.
But now im on the Custom Rom I am having no problems with wifi at all.
Hope this helps.

Actually, I would say try a different kernel. CF-root is a kernel. Wifi drivers are in the kernel. Ergo... ?
Wifi is kernel related issue
try changing your kernel
you mite wanna chk dis

Im having the same problem here, any luck so far?
may have something to do with the root. my phone had this issues once. just flash your phone with the correct rom and do NOT root it again as it may have something to do with the root itself. or just something got messed up during the rooting process
Hi,
I flashed new ROM on my Lenovo P780, its EU rom LiFe v0.7.
Everything is working fine and stable, but one thing isnt,
I cant turn on Wifi or Bluetooth.
When I try to turn it ON, the turning on animation appears, but it keeps coming back as OFF. So I just cant turn it on.
I was trying switch the ROM back to stock rom, but this Wifi error is still there.
Does anyone know what to do with this ?
Thanks a lot.

Did you make a full backup of your stock ROM? If not, you are doomed because of the WiFi and Bluetooth MAC address or NVRAM data probably have been wiped, thus you cannot switch on WiFi and Bluetooth at all.
Probably you can fix it, but I don't know whether it works or not though.

First rule with Mediatek phones, always make a full backup of stock ROM before making any mods to your phone.
I'm having an issue with the wifi not turning on (it stays grey saying turning on but never does) all other radios work, just not wifi. I cant get it to run on any rom except for stock. I am s-off if that helps solve anything. I've tried flashing boot.omg, I've tried other kernels, I went back full stock newest update.. still no good. If the Rom is custom WiFi refuses to turn on.
