I recently installed a Sparklan WPEA-111N (AR9280) into a new base station
that I'm building. I am specifically attempting to use the 5GHz bands (US),
as there is a significant amount of traffic on the 2.4GHz band around my
home (I live in a very dense area). The card itself seems to be working
correctly. However, when attempting to create a base station on the 5GHz
band, hostapd does not list *any* frequencies in mode=2 (802.11a) and notes
"wlan0: IEEE 802.11 Hardware does not support configured channel".
This does not seem to match the documentation, which indicates that channels
available in iw list should be usable as base station channels. I've tried
this on both hostapd 0.6.10 from the original Ubuntu 10.04 install, as well
as a rebuilt version of 0.7.2 (taken from Debian experimental). Neither
version works correctly. Log snippets I've found on this list and elsewhere
seem to indicate that I should at least see an "Allowed channel" entry for
the 5GHz channels.
Is this a known limitation with the ath9k drivers at this point, or is this
likely an issue in the hostapd code?
Relevant logs and configurations are below. Help and suggestions in the
right direction are appreciated.
