Do you have a WEP network because it doesn't work with the new driver used by the kernel
hi there, its easy as you say i think the problem is with permissions, give permissions manually to the wlan modules thenh restast or in cmw fix permitions and its working nice and easy.
do the trick worked for you???
Yeah,I've tried using WIUI, almost all versions of CM and I'm still unable to have a working Wi-Fi. I heard that there are some apps that can help me out, or am I wrong?
What happens: I click "connect", it tries to, but then fails and tries again.
Does Wi-Fi work in stock Rom? If not then you must check security settings in the Wi-Fi router. For eg. In WPA settings AES+TKIP does not work, only one can be selected.

Ofcourse it does. Only on custom ROMs it doesn't work.

Try changing the security to WEP , 64 bit.

Your problem cannot be for all custom roms. At the very least stock based stable roms such as ms2ginger must work. There are reports of Wi-Fi issues with the latest cm10 build and 2ndboot cm9, though I have had no such issues. Roms apart from these should not have any such problems. So if you're on such builds, try others such as ms2ginger.

what do you mean by saying that?
Does the wifi work if you go to the router? In a range of a few meter?

I fixed the problem by copying the wifi folder from 4.1.1 to 4.1.2

Do I need a rooted phone to flash the 4.1.1 version, because i don't wan't to root the phone. It can't be fixed by changing the pass type from open system to shared key from the router settings (this works for me but no one in the house can access the network, only I can)
Where can i find these folders ?:?:?

At a friends house, the first time you connect a new device to their router you have to use the wps button, otherwise it just sticks on authenticating. After that it works fine.

for all who experiene problems with wifi after updating from 4.1.1 to 4.1.2 here is the solution:
Root your phone (http://forum.xda-developers.com/showthread.php?t=1957273)
Download Root Explorer
Copy files from 4.1.1 /etc/wifi folder and overwrite over 4.1.2 /etc/wifi folder.
Youre good to go

It don't have nothing to do with that my s3 connects just fine do u think it could be the firmware or the kernel if so can u link it up for me
I have had two devices that did not like my cheap router.
One kindle and one pc. It liked other routers running the same settings.
A friend of mines s4 did this as well with his router.
It is not your device I'm blaming it is the router+device I am blaming.
Either take the suggestion or don't but it would be my first go to.

Here is the link if your /persist got formated.
Newest Philz will not let you format it anymore.
Maybe he will let us backup that partition soon?
