Airport Network not showing up on XBOX360

[actingbiz1]

I saw other people's posts about problems with their xbox 360 not connecting to their airport, but none of them mention anything about their network not even showing up when you scan for it.
My Xbox refuses to find my network or try to connect to it manually. I have an airport express.

how is your airport setup? Mine works like a charm considering its a MS product

The airport express base station has ethernet into the wall (its acting as the main router)
I have WPA /WPA-2 Personal
Auto Channel
802.11/n b/g Compatible.
No MAC Address Control

what do I do???
