D-Link Wi-Fi adapters have several versions and the drivers aren't
cross-compatible. Suspect you got the wrong one ! Look on the back of
the adapter and you'll see the version letter: A, B, B1, C, C1

Been there many times with this particular USB adapter and yes it's a
pain when there are so many incompatible drivers versions !!

As you say - any of them are plug-and-go in Ubuntu

R> Aaah, I think I have a D-Link usb adapter kicking around.
