I'am using this rom a few months without any problems.
Only the last few weeks a have a strange problem:
Sometimes when I switch my tablet on (from standby) wifi won't connect. In the statusbar the wifi symbol is empty. When I go to settings, I get an almost empty screen. Only the word "settings" and settings symbol and line is there.
If in the statusbar I click on wifi, nothing is happening. It won't turn off.
I can switch Blue tooth on and off.
When I reboot everything is working again.
At one or two occasions I saw the process wpa_supplicant consuming CPU. When I killed this process, settings was working again and I could switch off/on wifi again. It was working again without reboot.
Clear cache does not resolve this.
It is not always the case. A few times in a week the problem occurs. Before I never rebooted the system. I was always working.
I don't prefer to upgrade to 4.3. This version was working fine (until a few weeks ago).
What can be the cause of this ?
