Ideas?
Before running "iwconfig wlan0 channel 8", the card is set to
802.11a mode. iwconfig shows rate at 54Mb/s. But after setting the
channel, it sets to 802.11b mode, and I can't find a way to change
from 11Mb/s to 54MB/s.

"iwlist eth0 rate" only show up to 11Mb/s.

So, my problem is the card is always in 802.11b mode.

So I guess there is a common problem with a/bg modes?

Regardless of what iwconfig reports as the mode or rate, you should be able to associate to an AP in either spectrum (2.4 or 5.2) using any valid rate. Once configured and associated, iwconfig should provide more correct information.

If association is failing, verify that 'iwlist scan' shows the AP and that you specify everything for the association, eg:

iwconfig wlan0 channel 8 essid MyAP ap 00:13:f0:0d:ca:fe

d80211 will only attempt to associate once -- if it fails, then you need to currently "de-configure" the device and reconfigure it back to what you want to associate to. I do that here by chaging the AP BSSID to something else then changing it back. If you use wpa_supplicant, it does the re-association attempts for you.
