so... frickin'... close

i hooked up my XBOX360 today! i walked through the wireless network settings, put in my WEP password, all was going great, then the network testing. it stumbled a few times, i had to reboot my router once, now i'm stumped. i pass all of the network tests, but when it gets to the "XBOX LIVE" test, it fails and doesn't tell me how to fix it. i checked xbox.com and couldn't find anything. i asked their tech support. we'll see what they have to tell me. any ideas? i was hoping to surprise you guys with a guest appearance, but i guess that might not happen for a bit. until then, i'll go warm up. thanks.
