Hmm… I had it all the time, but it only worked on Windows.

Its a Linksys USB54G, which does 802.11G. The only way I know of getting this working under Linux, was using ndiswrapper. Now I had it installed and configured earlier, but the load average peaked at 100%, with my laptop battery draining in no time. Now, I believe (I might be wrong) this was because of a continuous poll on the usb port to check if there were packets.

But the good news. Don’t know when this version got released, but apparently it fixes this problem.
