I am currently running my Xbox through wi-fi and lately have found the lag to be ridiculous. VMA in particular is a lag fest. I tried to connect my Xbox via a hard line internet connection hoping that would remove some of the lag but for whatever reason my Apple Airport Extreme does not play friendly with my Xbox via ethernet. I tried looking online for a way to setup the airport but so far haven't been successful.
I am hoping someone here might know the magic settings needed to make this work. Would appreciate any insight.
