Was on Official stock ROM JB 4.1.2, did the official update to 4.2.2 and WIFI was dead but with MAC address
Rooted and flashed LiquidSmooth ROM with 4.2.2. WIFI remained dead without MAC address
Erased data, factory reset, wiped dalivik cache, flashed wanamlite ROM with 4.1.2. WIFI remained dead, but occasionally turning on and hooking up to my router for about less than a minute then went dead again. MAC address is available.
Erased data, factory reset, wiped dalivik cache, flashed Avatar rom with 4.2.2. My MAC address disappear again.
Now i had restored to wanamlite rom with 4.1.2. WIFI is still unable to be started up but MAC address is there.
This WIFI problem has been bothering me for a while now and i really hope to get help from an expert to help resolve this sticky problem.
