I'm now convinced it's either my xbox or the firmware I installed (ixtreme 1.3)

I hooked my adapter on a friends xbox and it works fine, so its not the adapter
I hooked up VIA ethernet to my router, so I'm not banned

I tried all 3 USB ports, and my Adapter is detected...and detects networks, it even says it's connected to my network....however, when I test the connection It says "Wireless Network: Not Connected"

So anybody have any idea's on what the hell is going on ?
