Unhappy [Q] Wifi shows connected but does not work.

I have a Samsung galaxy S3 on S3Rx 3.0 (4.3) rom. I have tried other TW roms for 4.3 and every kernel out there to try and fix Wifi connect-ability. Wifi is connected and shows that there is 21Mbps of connection but no pages will load. Per the install instructions for the TW 4.3 roms it says to flash the kernel after the rom to get Wifi working but it doesn't. Anybody else having this issue or have fixed this issue.
