On my windows xp home edition computer i have a cross over cable between my computer and my Xbox. My computer is receiving wireless internet from the main computer downstairs. i have always been able to get on XBOX live (internet on the Xbox) VIA the cross over cable. BUt my computers LAN connection at first said little to no connection, and after i put in the IP address and other stuff VIA TCP/ip protocol properties manually it just says acquiring network address and never connects. What can i do????
