i have my imac in my bedroom and my xbox in my living room. i would like to use xbox live thru the dsl connection i have set-up for my imac. running a crap load of cat 5 cable is an ABSOLUTE last resort. can i use an airport base station connected to my x-box and an airport card in my imac? will the surfing speed of my imac suffer greatly? the 2 will be approx30 feet apart, separated by 2 indoor walls. thanks for any help
