I just got a wireless laptop using windows vista, i have a desktop using xppro and xbox 360. desktop and xbox are wired and can get on together no probs. when i get online with the wireless lap top the xbox and the desktop both disconnect, i wanna be aable to get on the laptop and the xbox/desktop at the same time. im using a wireless-B linksys which they said should be able to do both at the same time but the wanted an arm and a leg worth of $ to tell me how to do this. any help would be greatly appreciated, thanks!

Posting the exact make/model of the router would be helpful. Go to Linksys' website and search for the manual. Download it and read it through thoroughly before attempting to set it up. Wireless "b" is old. Wireless "g" is the present standard and the wireless "n" is almost ratified into a standard (should be real soon). Each is progressively faster so you have "b" as the slowest and "n" as the fastest. Your equipment should probably be "b/g". Which means it's "g" but backwards compatible with "b" as well.
