Today I googled the problem for the hell of it: The solution was very easy (I take no credit for this), and I'd not read this on XDA so thought I'd share. When connecting to a wifi network that requires authentication, make sure you forget the network, instead of clicking on the network to add your information, touch the add network button and manually put in the SSID, your user name and password. Voila, it worked instantly for me.
So here's what happens. Occasionally after I flash roms my wifi acts up. It will connect to open networks just fine however when I try to connect to my work network using my User name and Pass word the wifi just says Saved,(and some other word can't remember). Needless to say I assumed this was something that happened after repeated rom flashes. So in any case I'd ODIN back to a stock and it would fix the problem ( I've actually soft bricked my phone many times trying to fix this at work).
