[ath9k-devel] trouble with DWA-552 and ath9k

[Brian Walker <walkerbm@charter.net>]

I recently purchased a DLink DWA-552 that I would like to use with 
hostapd as an access point. The ath9k driver claims the chipset is:

Atheros AR9280 MAC/BB Rev:2 AR5133 RF Rev:d0

I have tried both the ath9k that comes with my distribution (Fedora 11) 
in the 2.6.30.9-102.fc11.i686.PAE kernel and also downloading, building 
and installing the latest compat-wireless-2.6.tar.bz2 with date 
2009-12-11 and rebooting.

In both cases, I am unable to find any access points when doing an 
iwlist wlan0 scan while other 802.11 devices in my home find several 
access points from nearby neighbors. I have also tried both hostapd 
0.6.9 and 0.7.0. When I try to run hostapd to put the card into AP mode, 
I get the error:

nl80211: Failed to set channel (freq=2412): -22 (Invalid argument)

I don't know if it is supposed to, but the LED on the card itself never 
comes on.
