You didn't mention an Airport Base Station, so I assume you are trying to
connect directly between two computers, each having an Airport card.
In the new laptop, be sure that TCP/IP is set to use the Airport card rather
than Ethernet or Printer ports, and that Airport is turned on in the Airport
Control Panel. If you are using AppleShare or AppleTalk printing, be sure
AppleTalk is set to use the Airport card as well.
