I'm new in Linux at all and I just installed Ubuntu on virtual machine. The problem is that there is no wi-fi network. On cable no problems but when I unplug lan cable there is no wi-fi.
So far i tryed to 'Software Update' but I don't see update for wifi driver or something.
What can be the problem? Can you point me what and where to check?
This happen also on real not virtual machine. Laptop is Dell Vustro 1500. Only wired network and no wireless?
