Verify that the `lspci -n` lists the card.  Agree with Lou here, please send
the Vendor:Device combo, or verify that the ath5k driver will list it.  IME
each drivers' source has a enum list of ID strings for the devices that it
supports, and occasionally (I have delt with this regularly with
3G/GPRS/EVDO "Air" Cards, as the drivers do not often include the newer
devices, so that the driver will not load since it does not "recognize" the
device, so hack/recompile driver source is required untill the distro
updates it kernel and drivers.

Also, what network manager are you using?  I'm not a Unbutu

Check your /etc/modprobe.conf and/or the /etc/modprobe.d/* files (blacklist,
module-renames, unsupported*) to make sure that the proper alias is
defined.  Sometimes, you need to `ifconfig wlan0 up` explicitly before your
iw* tools will "see" it.
