Does the card really have an Atheros chip set? Otherwise that driver
probably won't help. Furthermore, the madwifi driver is available in the
package linux-restricted-modules. There is no need to install from
source, although it would surely work. It is just far easier to use the

Well, if the module is not yet loaded, such a device doesn't exist. But
you could check with the command "ifconfig -a" which devices are

Then your card isn't supported by the madwifi driver, unless you made some
mistake during the installation.

Reinstalling might help with Windows, but with Linux that only helps very
Let's check, what type of chip set your card uses. Please post the output
of the command "lspci -v".
If it is really an Atheros chip set, you could install the
linux-restricted-modules package using your favourite package manager,
e.g. synaptic. Then use the command "sudo modprobe ath_pci" in a
terminal. If the card is found, the command "ifconfig -a" should now show
a device ath0.
BTW: Which Ubuntu version are you using?
