Just started up Parallels/XP on a new MacBook. Under Network Connections, no wireless card shows up. Do I have to 'install' the built-in wireless card within the Windows OS, in order for it to recognize that the machine has a built-in card? Do I have to "stop" the MacBook's wireless before trying to use that hardware from within the guest OS (which is XP)? Network Adapter 1; Shared Networking appears on the Parallels config page.
