[4.3]Fix for Wifi Scanning (Testers needed)
As many of you know, since the 4.3 update, WiFi on the galaxy nexus stops automatically scanning after going into deep sleep. The only way to get it to scan again is to go into the WiFi menu or toggle it on and off. Let's try to find which change in 4.3 broke this on the galaxy nexus.
I have been looking through the changes that have been made between 4.2 and 4.3 to how wifi is handled and may have found what is causing the issue.
I think I may have found something. In /system/etc/wifi/wpa_supplicant_overlay.conf
Theres a line:
disable_scan_offload=1 (has to do with allowing scanning to be offloaded to the driver)
This line didn't exist in 4.2.2. Change it to 0 and reboot and see if your wifi scanning doesn't stop working after a while.
I just ran an errand and it connected perfect when I got home which is usually when it stops working. I need further testing but would appreciate some more testers to see if there's a real change in behavior.
