I finally found the solution from the following web site: http://ubuntuforums.org/showthread.php?t=769990&highlight=BCM94311MCG
The key is that we need to append the following lines to /etc/init.d/rc.local # ------------- #hardy ssb bug-fix rmmod b43 rmmod b44 rmmod ssb rmmod ndiswrapper modprobe ndiswrapper modprobe ssb # ------------- That is done by running the following command: ( echo -e '\n#hardy ssb bug-fix\nrmmod b43\nrmmod b44\nrmmod ssb\nrmmod ndiswrapper\nmodprobe ndiswrapper\nmodprobe ssb' | sudo tee -a /etc/init.d/rc.local ) *** Of course, I backed up my original rc.local before running such command. -- Dell WLAN MiniPCI card not working with built-in drivers or ndiswrapper 8.04 https://bugs.launchpad.net/bugs/220365 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
