I am not able to use my laptop as a WiFi Hotspot.
I guess the problem is in the driver, because even when I am trying to create ad-hoc network from windows it is not working.
I tried installing ndiswrapper, then I tried the command
ndiswrapper -l

To which it is showing
Error: Unable to find a version of ndiswrapper!

Am I supposed to install a separate driver for Ubuntu?
I don't know anything much because I am a new user.
