cm-12.1: Wifi doesn't work

[diepquynh]

It only work on first start, then when we disable it, then enable it, it's dead until we remove /data/misc/wifi folder. Logcat: I/wpa_supplicant( 901): rfkill: Cannot open RFKILL control device E/wpa_supplicant( 901): Could not read interface p2p-dev-wlan0 flags: No such device

@ngoquang2708 Any ideas bro?

[ngoquang2708]

What is permission of /data/misc/wifi folder before and after reboot? Are they both the same?

[diepquynh]

Yes they're. Here I just disable then re-enable WiFi, it dies

[ngoquang2708]

The rfkill part is not importance. The importance one is that why wpa_supplicant cannot detect p2p-dev-wlan0 device.

[ngoquang2708]

What is the permission anyway?

[diepquynh]

It seems the problem comes from the source itself, because WiFi still working properly with my CM13 with the same configuration

[diepquynh]

And the same for you with WiFi direct before

[diepquynh]

[ngoquang2708]

What about the permission of the /data/misc/wifi directory?

[diepquynh]

[ngoquang2708]

Okay, it seems normal, so what...?

[diepquynh]

I have to delete /data/misc/folder to make WiFi work once I disable it or reboot the phone

[ngoquang2708]

Have you tried this: reboot to recovery, remove all the contents of the wifi folder, then set permission for it, then reboot.

[ngoquang2708]

I got this issue in CM14 too, but not on AOSP7. But instead of dead, the wifi crash the system. I don't know why.

[diepquynh]

OK, let me try

[diepquynh]

Set the permissions like the above screenshot right?

[ngoquang2708]

Yes

[diepquynh]

OK this method doesn't work for me

[ngoquang2708]

OK. Can I get full logcat before and after wifi is enabled?

[diepquynh]

Here's the one after fully booted, and connected to a network wifi.txt

[diepquynh]

And the one after disabled, then re-enabled WiFi wifi2.txt
