Linux WiFi driver

This adapter should be automatically supported in recent distributions with the ath5k driver. However this driver might be unstable unless you have at least kernel 2.6.29. For the WiFi activity LED to work, you need at least kernel 2.6.31.

Alternatively the Madwifi driver works with this adapter.
