Post [Q] Jelly Bread- WIFI not working

after i successfully installed the rom, now, whenever i turned on the wifi, it doesnt even try to scan for networks. i already tried changing the broadcast channel of my router to 1 to 11 and still no luck. i have also tried the tiwlan.ini editing, but my original tiwlan.ini is already in right options. i tried also factory reset, still no hope. i'll turned the wifi on , and for about 10 secs or 7secs, it will automatically turned off. Can you help me guys!
