I've already tried it out. Didn't help.

I think it's a lot like: https://bugzilla.mozilla.org/show_bug.cgi?id=890974#c0

Nope. I was wrong. Permissions seems to be ok:

shell@android:/data/misc/wifi # ls -al

-rw-rw---- system wifi 21 2014-01-13 16:30 entropy.bin

drwxrwx--- wifi wifi 2014-01-12 18:22 hostapd

drwxrwx--- wifi wifi 2014-01-13 16:30 sockets

drwxr-x--- wifi wifi 2014-01-13 16:30 wpa_supplicant

-rw-rw---- system wifi 74 2014-01-13 16:15 wpa_supplicant.conf

Can you try to turn on the "wifi output in adb" setting? It can be found -> settings -> device info -> more info -> developer settings.

The dev couldn't reproduce the issue when that setting was turned on. Otherwise, if you can turn it on as well as the output to adb, we might be able to capture the log to get more information.

Uh guys, I'm really sorry. That was my fault. I forgot about MAC filter. Thank you for your help.
