I have been looking for a solution for this since Friday and nothing.
I have tried the following:
Restart and nothing
Airplane mode on and off and nothing
Several factory resets and cache wipes and nothing
Reloaded 4.3 thru Kies and nothing
Tried to load 4.1.1 thru Odin 3.07 and it fails which I dont know why
Tried some Wifi fixers from the market and nothing
Im lost now and cant seem to find any other info.
