Hi guys,

Just a quick little guide on how to fix the wi-fi and bluetooth issues on the official cm11 nightlies!

You find the official cm11 a bit laggy? you thought it would be a great idea to install williams kernel V2? after installation you noticed that it runs so much better and are really happy with it till you notice that wi-fi and bluetooth aren't working? Well here is a simple fix for that!


1: download these 2 files: (credit goes to @alcatraz999902)

2: navigate to system/lib/modules and delete wlan.ko and scsi_wait_scan.ko

3: copy the files you downloaded earlier (wlan.ko and scsi_wait_scan.ko) to system/lib/modules

4: change the permissions to rwrr:
A: you can use file explorers like es file explorer to change the perms (rwrr 644)
B: you can also open a terminal, mount your system as rw (mount -o rw,remount /system) and cd to /system/lib/modules then type these 2 commands:
chmod 644 wlan.ko
chmod 644 scsi_wait_scan.ko

5: reboot your device

6: Enjoy official cm nightlies with working wi-fi and bluetooth!

Wow many thanks, mate!! I didn't know what was happening to the wifi. Now I can even solve it.

By the way, when you update a nightly, you need to readjust options like in built kernel mpdecision or reinstall optimized qcom's and all that stuff?

I suppose that's not a fix for wpa problems?
(since a long time, wifi doesn't work on WPA in cyanogenmod... only work with wep or wpa2)
But anyway, thanks for sharing

I think that kernel already has the correct modules
