Xbox live and 802.11a

Xbox Live and 802.11a. I’m trying to figure out if this combo will work well. My xbox is in one of the few rooms in my house without a cat5 tap and so I want to use 802.11a to bridge the xbox onto the lan. I can find little info about this config on the net. Officially, Microsoft says it won’t support wireless connections. But on the xbox forums, many people have said they made it work. Many of them recommend the Linksys WET11 bridge. I’ll probably try that.
