So I'm facing this problem for a while now . What happens is that my phone reboots automatically sometimes and after the reboot I can't use my WiFi . The button is stuck at off:

So after doing some research on this I wiped my /data/misc/WiFi folder to fix it (didn't create a backup though). So the problem got fixed but it came back again. So I wiped again and it didn't work this time.

In order to restore the folder I copied the WPA_supplicant files in the folder manually. But I don't know what permission to set it to . And even if I change the permissions it gets reverted back to 0660. Also I don't know whether the the .conf file is even compatible for my phone as I got that one from an XDA post.

Can anybody guide me how I can fix this ?

  • It's not just the permissions, it's also the ownership – which is not clear from your description/screenshots. Not sure if there are device specific differences; AFAIR they must be owned by system, but I cannot remember the group. Commented Apr 28, 2017 at 14:41

  • once you restored the permissions and owner/group, you may need to run this from the adb shell: restorecon -Rv /data/misc/wifi/wpa_supplicant.conf Commented Nov 5, 2017 at 23:39

On my phone permissions and ownership looks like:

ls -las /data/misc/wifi/ 12 drwxrwx--- 4 wifi wifi 4096 2017-08-14 16:30 . 8 drwxrwx--t 39 system misc 4096 2017-08-12 20:54 .. 8 -rw-rw---- 1 system wifi 21 2017-08-14 16:30 entropy.bin 48 -rw-rw---- 1 system wifi 43098 2017-08-12 22:36 hostapd.conf 8 -rw------- 1 system system 3136 2017-08-12 23:27 ipconfig.txt 52 -rw------- 1 system system 44517 2017-08-14 16:30 networkHistory.txt 4 -rw-rw---- 1 wifi wifi 186 2017-08-14 16:30 p2p_supplicant.conf 12 drwxrwx--- 2 wifi wifi 4096 2017-08-14 16:30 sockets 8 -rw------- 1 system system 20 2017-08-12 22:36 softap.conf 12 drwxrwx--- 2 wifi wifi 4096 1970-01-10 00:56 wpa_supplicant 16 -rw-rw---- 1 wifi wifi 10957 2017-08-14 16:30 wpa_supplicant.conf
