I'm getting the above message when I try to setup my wireless in my laptop. I found the rt61.inf driver from the windows partition, and still get that message.
When I type "ndiswrapper -l" it says:
rt61 invalid driver!
But that's the driver it uses under windows...
I'm on a Averatec 7100 series laptop.
I also can't get it to find the integrated network card (not wireless) but that's not a big deal right now.
