I just fired up my Thinkpad T510 with an Intel "Centrino Ultimate-N
6300" using iwlwifi, and it stays connected (does not appear to drop any
packets).  This is also Fedora 18 x86_64 (slightly older kernel, but
I've had the problem on the MacBook since I installed it).  There are
other people in the office with the same MacBook hardware (but running
OS X) that don't appear to be having any trouble either.

The AP appears to be an Adtran (don't know the model).
