Revert Ndiswrapper After Installing Wrong Driver on Ubuntu
 

Well, thanks to some website, I installed the wring driver in Ndiswrapper, and being a total noob, have no idea how to install the new one and remove the old one. So, how?

To see which driver is installed
ndiswrapper -l
to remove the driver
ndiswrapper -e driver

Download the windows driver for your wireless card, and do :
ndiswrapper -i path to your driver
ndiswrapper -m
modprobe ndiswrapper
