I am running this exact configuration, and it works fine. I have heard of this problem on other access points (Specifically the linksys AP 2.5), and there is somehow a relationship with encryption and encryption size. It should work if you turn off encryption, but I don't know what the root cause is.
As I said, I'm running with 128 bit encryption and bridging, and everything works fine.
