srsly? No answers?
FWIW, I also don't get a connection. I restored my APs using a titanium backup taken from stock lollipop. All APs appeared to have been restored ok, and I did see the list of available APs in the vicinity including my router, but I just didn't get a connect.

Edit: I've done some more research and it seems that those issues are related to the Fritzboxes AVM, though I have no idea what makes them special. Maybe some detail about the DHCP implementation or so.

follow all steps from post #5
You need adb on your PC and root access. All guides are available in the sticky threads.

how is the command for BT please? coz it doesnt work neither :(
BT?
Do you have ADB on your PC? Do you have root access on your device?
First off, use the command adb devices to check if the device is correctly connected & recognized.

SOLVED by repairing permissions, but if any of user have same problem can simply do this:

The solution was to simply change ownership back to system:wifi
$ adb root
$ adb -d shell
# cd /data/misc/wifi
# chown system.wifi wpa_supplicant.conf
# reboot
I have a rooted One X (Evita) and I can't get the wifi to work pass any cm11 nightly released after June of last year. When I install any of the nigthlies after that date the wifi won't turn on and the problem has transitioned to cm12.

I know it's not a hardware problem because the wifi works with an older cm11 nigthly. Can anyone please tell me what to do because I tried almost everything including the solution posted in this thread.

Hi @hexen88, i tried the above and it worked perfectly for a while now. and since yesterday i am having same problem, and by using the above trick it works for a while then again my wifi stops working. Can any thing else be done? :confused:

Hi @hexen88, I've trying your solution but it doesn't work on my nexus5 :s. Actually I don't have any system.wifi file :/. I have tried a lot of things but nothing works.
