xbox 360 will not connect to wireless network?

the wireless network is available to choose, but after I put in the WEP key, it checks for a few seconds and then says "Test failed" ... it's the right key because I put it into my laptop again just now and it connected fine. It's really frustrating. Help someone?

Also, I have connected the same console to the same network before without any issues.
