AVM provides a proprietary licensed driver that is only tested on outdated SuSE Linux platforms and not updated since the initial release. Getting it to work in Ubuntu 8.04 requires modifying the drivers source code, compiling the kernel module yourself and getting it more or less to work: WPA/WPA2 works, no link-quality display, problems with Network-Manager. Why not release it as Free Software so people can improve, update and put it in a working state into every major Linux distribution?
