I brought my new Airport Extreme Base Station online last night, and it did indeed solve all the problems I was having with a D-Link DI 624. The DHCP server is not having any problems with two TiVo's, two PC laptops, two PC desktops and my C2D MacBook. Cool. I presume that the Airport Card in the MacBook got the "n" upgrade when I did the AEBS Airport Utility installation, as I had to reboot the MacBook, however, I can't seem to find anywhere an indication of what speed the Aiport is connected to the base station. Is that information available somewhere? Is there a way to tell if the "n" is enabled?
