Default [Help] Wifi issue on ROMs

Hey guys, I've run into a fairly significant issue on my tablet. I can't seem to connect to my Wi-Fi. It'll recognize it and pick it up, but when I type my password in, it drops down to one bar even if I'm standing directly in front of it. It'll then bounce back to full bars after a few seconds but will only show the status as saved and won't connect.

I figured that this was an issue with the first CM ROM I flashed, so I tried another few. They all did the exact same thing. It's evidently not a hardware issue since it will connect easily on the stock rom.

I'm on a V500 running 4.4.2, V50020B.

Any help or advice on this would be greatly appreciated.

Thanks!
