Yes it does, including operations with encryption enabled, and it is identical in form factor and part number to my other Airport card; it has the cutout end section that allows the antenna connector to be attached and not protrude beyond the PCMCIA outline in the length dimension. I'm mostly using my Sawtooth in hardwired Ethernet mode, but this will allow me to move it to other rooms if necessary more easily. I did not test the Airport Base Station part at all. I have plenty of wireless routers in my spares bin already, and from the disassembled condition I figured someone else had already had some "fun" trying to get it working... [] ]'>
