I live in an apartment that's on the second floor of a house, and my landlords live downstairs. They are putting out a wireless signal, and currently i have a Lynksys Wireless adapter plugged into my computer to pick up the signal. My XBOX has built in WIFI and can't pick up the signal. The Lynksys company told me its because my wireless adapter doesn't work with XBOX. Is there any wireless adapter that plugs into my computer that will allow my XBOX to pick up its signal, or what is going on? I have had my xbox for 2 years and never been able to use LIVE, HELP!!??!!
