Here's the shell script I used.
So 11g works, and only 11n mode is broken? Your AP probably doesn't support 11a mode. > BOF > #!/usr/bin/env ksh > > echo "shutting down athn0" > ifconfig athn0 down > sleep 15 > echo "starting up athn0 in 11g mode" > ifconfig athn0 mode 11g join "Portable Hotspot" wpakey ************ > up dhclient athn0 > EOF > > Thanks for the suggestion.

No, your assumption was entirely correct; by default a mode which is compatible with the AP should be chosen automatically. Forcing a mode is only useful for debugging purposes. 11n mode should work with your device. I will see if I can figure out why it does not work, but I don't yet have much information to go on and I don't have access to this hardware. If you could test kernels of older releases and check whether 11n mode was working at some point, that would help me.
