I bought my MacBook Pro and a brand new Airport Extreme to go with it about 4 months ago. I have the MacBook and my wife's iMac hooked up wirelessly to the Airport Extreme with no problems. My son't Wii also hooks up with no problems wirelessly. My Xbox 360 hooks up sometimes, and sometimes it doesn't. It's not wireless, it's hooked directly to the Airport Extreme via Ethernet cable. When I first got the Airport Extreme, the Xbox had no problem hooking up to it and the internet. But lately it sometimes hooks up, and sometimes it doesn't...with no explanation as to why other than maybe the position of the planets or something. Restarting the Airport Extreme helps sometimes, sometimes it doesn't. I'll just leave it be for a few days...change nothing...and then try the Xbox again and automagically it seems to work...for a few days. Then for no reason will just stop again. It can't connect through anything then, not even hook up to one of the Mac's using Connect360. It's as if the 360 is not even hooked to any network then. Also, the Xbox 360 had zero network problems when I was using a DLink router, which was the set-up to hook to the internet and the hub of the home network for the past year. The 360 could hook to the Macs and access the Internet. But the Dlink wasn't wireless, which is why I went with the Airport Extreme when I got my Macbook Pro. Again, everything else works beautifully, just not the Xbox 360 for some strange reason.
