(possible WIFI Fix) Let's try to figure out why WiFi stops auto scanning
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. It works fine on both nexus 7s. Its also not related to any particular router as the issue is the phone doesn't scan for WiFi.

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.
