Galaxy SIII GT-I9300 WIFI problem.

Hello,
Recently my s3 wifi has stopped working... it wont connect to any wifi and would simply "save" it but wont connect(it says connecting for a few seconds but doesnt connect). Ive had this phone quite a long time and ive rooted it and flashed roms a lot aswell but for six months or so i just flashed the samsung stock firmware for it and have been using it no problem bu suddenly it stopped working. i tried resetting, flashing ROMs, trying another stock firmware did te wifi power saving thing but it still doesnt work. What i saw was when i like reset the phone with the sim card installed the wifi wont work but when i reset the phone without the sim the wifi will work but when i insert the sim back again itll stop working again. i tried changing sims but still asme result. Any help would be appreciated.
Thanks

Need help please: WIFI stuck on 'turning on'. MAC Address - Unavailable

Hi everyone.
I have not been using my Mi Pad 1 for quite some time now. Recently, my brother installed an app that allows him to disable other users from connecting into the wifi. He stopped using the tablet because the wifi detects the network but does not connect (stuck with "saved"). I tried removing the SD card and restoring factory settings but still did not work. I also tried connecting it to a different ISP but it didn't work. All other devices are connecting to the home wifi with no problems.
I flashed the tablet with CWM and cyanogenmod 11 on both systems 1 and 2. Same thing. I was detecting Wifi but not able to connect.
I have also tried modifying the router settings as usually suggested by other users. Still not connected.
I also tried renaming WPA_supplicant.conf to WPA_supplicant.bak - it did not work as well
I have tried draining the battery completely and charging it again until 100% charged. Righty now, the tablet wifi is stuck on "turning on" status.
This is actually my first time doing a root, custom recovery and custom ROM install. I am really impressed by the guides posted here in XDA. I really hope there's still a solution to my problem.
Thanks for all the help!
*******I don't think it is a hardware issue because the tablet still detects available networks and is able to connect to bluetooth devices.
Hello.. Did you fix your issue?
