I don't have internet on Ubuntu so I can't download ndiswrapper from the software center.
So I downloaded the tar.gz file and copied it to my desktop on ubuntu.
I go on terminal and type
Then I type in
tar -xz ndiswrapper-1.57.tar.gz
And then my terminal just freezes. I let it sit for 25 minutes and it was still frozen.
So I tried to close terminal and it said it's doing something so I shouldn't close it.
Is it supposed to take an hour to extract the file?
