I recently just installed Ubuntu 12.10. Everything was going well and I really enjoyed it, so much that I installed it on my desktop, however my desktop does not have a built-in wireless card, so instead I'm using a usb adapter. When I installed Ubuntu though, it does not have the proper software to recognize and run the adapter, therefore I cannot connect to the internet. I did some research and many pointed to "ndiswrapper" and how I should use that, after going through many other steps (which I don't know how to do either), and it should work! Well...as I don't have internet access via that computer, I've been trying to use a USB drive; downloading the 'tar.gz' files, but I cannot get them onto my other system because when I 'copy and paste' the supposed file, nothing happens, therefore I can't even begin the other steps appropriately.
I need any help as to how to get the necessary files on my PC without internet access, via USB drive
Then I need to proper steps as to how to install ndiswrapper and whatever files I'll need for my Netgear WNDA3100 USB adapter
