lspci | grep Atheros

05:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)


auto lo
iface lo inet loopback

allow-hotplug eth0
auto eth0 
iface eth0 inet dhcp
#auto wlan0
#iface wlan0 inet dhcp

I tried disabling eth0 and enabling the wlan0 lines
and /etc/init.d/networking restart.

However I think that isn't any better than manually

	ifconfig wlan0 up; dhclient

I've found something else now: the madwifi drivers appear to
work for this:


I'll post to the list if/when I get this working.

Thanks for your suggestions!
