I just put Ubuntu on here along with Windows. I need to get the internet set right now. I have a Microsoft MN-720 card that I have in my notebook. Does anybody have any tips on how to use ndiswrapper to get cards to work? I don't know much about Linux and would like to try and get my network running. I have the wireless already set up and I just need to get the drivers for the card under Linux I guess. Any tips or ideas how??? Thanks.

Here's some sites a quick google search turned up:

Link 1
Link 2

Both seems to be aimed at SuSE, but it should work on Ubuntu with some minor modifications. If you need more help you might have to ask on Linuxquestions or some other linux-specific forum.
