[Voyage-linux] Voyage setting frequency on CM9

[Colin A. White]

Hi Folks,

I'm running 2.6.8-486-voyage on Wrap2.C  with Wistron CM9 Atheros 
802.11a/b/g miniPCI wireless card.

This is supposed to be a tri-band card (http://www.pcengines.ch/cm9.htm) 
but mine seems to be stuck in 802.11a mode (5.2Ghz). How do I reset this 
for 802.11b (2.4Ghz)?

> ath0      IEEE 802.11a  ESSID:"orbit8.net"
>           Mode:Master  Frequency:5.2 GHz  Access Point: 00:0B:6B:35:FB:B6

>           Tx excessive retries:0  Invalid misc:0   Missed beacon:0

my /etc/network/interfaces:

> ##  miniPCI wireless interface ##
> auto ath0
> iface ath0 inet static
>     address 192.168.190.254
>     netmask 255.255.255.0
>     broadcast 192.168.190.255
>         up iwconfig ath0 mode master

>         up iwconfig ath0 channel 6
>         up iwconfig ath0 rate 2M
>         up iwconfig ath0 key off

I've read the man pages for iwconfig and iwpriv and tried -

> Wrap26:~# iwconfig eth0 freq 2.422G
> Error for wireless request "Set Frequency" (8B04) :
>     SET failed on device eth0 ; Operation not supported.
> Wrap26:~# iwconfig eth0 channel 3
> Error for wireless request "Set Frequency" (8B04) :
>     SET failed on device eth0 ; Operation not supported.

Nothing seems to work. Can anyone help?

Thanks
