I was having the ndiswrapper instead of wext problem as well, with a rt2500 device using ndiswrapper ( The native driver wouldn't associate as well, but that's another issue). I was manually using wpa_supplicant to get around it.
jpierre's packages solved the problem. Also, ndiswrapper worked for me in OpenSuse 10.1 as well. -- Cannot associate with unencrypted networks using bcm43xx chipset (ndiswrapper driver) https://launchpad.net/bugs/42504 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
