[xubuntu] Problem with wireless [Atheros AR242x]

[bbandruin]

I've recently bought a nice laptop (Asus X50SL) to try out some Linux distributions and Xubuntu seemed like a good start. But now I want to get my wireless working and I'm having some difficulty with that. I've browsed the forums here quite a lot, but haven't been able to find an apt solution.

lspci gives me:

02:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

So my card is detected, right?

sudo lshw -C network:

iwconfig gives me:

lo        no wireless extensions.

eth0      no wireless extensions.

iwlist wlan0 scan:

wlan0     Interface doesn't support scanning.

No problems with it being not detected, it just doesn't show up as a wlan device?
I've tried getting it to work with madwifi, but that doesn't work. (And I don't have the cd-rom with drivers with me right now.)

Any suggestions as what I'm doing wrong/can do?
