since I have some problems with my download speed under ubuntu (see my other question) I installed ndiswrapper to load windows driver for my wifi card. Unfortunatly it didn't worked very well so I deinstalled ndiswrapper. But now in network-manager-applet the option to connect wifi is also gone.
How can I load the standard wifi driver or even better how can i activate the wireless backports driver so that it works with network-manager-applet?
I found an advice via google to use sudo modprobe wl but this gives the message FATAL: Module wl not found.
