Hi, I have the same adapter and i got it running under Ubunutu 6.06, SuSE 10.0 & 10.1 and Debian.
What you should do is intall the NetRTUSB.inf file from the cd drivers and not the one you used, it should be easy from there so long as after the steps you did above, you should type
Code:
sudo dhclient wlan0
or
you need to find what your wireless card is labelled as in iwconfig as sometimes it is not wlan0 but rausb0 or sumthing, this is specific to ubuntu and some debians.
There is a tiny thing that is of importance, and that is some distro's i need to use the windows 98 drivers on the cd with ndiswrapper and in some distros i have to use windows xp drivers with ndiswqrapper. Tried and worked with version 1.12 and upwards.
Try both and if u cant do it, i'll post a mini walkthrough of how i did it.
