This could be an isolated incident, but I managed to connect at 802.11n
speeds starting today after several system updates I made to a MBP 8.2
that is tri-booting Snow Leopard, Ubuntu 12.04 and Windows 7. These
updates include the latest Kernel 3.5.0.29 and Airport updates
# so wl was loaded for it this time, previously I had been using the latest b43
via
# firmware-b43-installer_017-1~experimental2_all.deb and
b43-fwcutter_017-1~experimental2_amd64.deb
