Comment 72 for bug 339891

last time I disturb you ;-)

just for newbies like me. it worked with the instruction on the following link:

https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/339891/comments/47t

but you have to replace two lines as follow:

wget http://launchpadlibrarian.net/25979268/rt2860sta-connect-to-mixed-tkip-aes-routers.patch
by
wget http://launchpadlibrarian.net/26192677/Patch%20for%20rt2860sta%20driver%20for%20WPA1-2%20connection%20v1.8.0.0%2B.patch

and

patch -p1 < ../rt2860sta-connect-to-mixed-tkip-aes-routers.patch
by
patch -p1 < ../"Patch for rt2860sta driver for WPA1-2 connection v1.8.0.0+.patch"

now it works fine with me (thanks to Dries)
