[App_rpt-users] Question on computer internet connection

Group, I see several people running mobile nodes, I am guessing that this is accomplished by using a usb modem or some other cell type access. I am looking to relocate my pc from the room that houses my router. I would like to use a wifi adapter and use a wirless link. I woudl appreciate any information on adding a way to use a wireless usb adapter instead of the LAN cable.
