This is a HOW-TO on getting the Netgear Wireless WNDA3100 USB Adapter working in Ubuntu.
At work we are switching all computers over to Ubuntu OS. On one HP system with Ubuntu 10.04 LTS now installed, we wanted internet access, but only on a temporary basis to perform updates or install programs from the Ubuntu Software Center.
Since we did not have an ethernet cable to this computer, the quickest way to connect to the internet would be a USB wi-fi adapter which we already had. After plugging it into our Ubuntu system, nothing happened. We needed a driver. Here is how to get it going....
Open the Synaptic Package Manager (System - Administration) and do a search on "ndiswrapper" and install the three items as in the photo below. Those are: ndisgtk, ndiswrapper-utils-1.9, and ndiswrapper-common.

Now that those are installed you'll need to download one or both of these Netgear drivers...
ndis_wnda3100.zip (158 kb)
ndis_bcmwl.zip (861 kb)
The first driver works for many people, but did not work for us. We had to download the second one and use the second one. Unzip both of those ZIP files. You are going to use the .inf files in each.
OK, you have installed those three ndis items in Synaptic and you have downloaded one or both of the ZIP files, unzipped them and now have the .inf files someplace easy to get to like on your Desktop.
To get the driver going, plug in your USB wireless adapter and go up to "System - Administration" and go to the bottom of the menu list and click on the newly installed "Windows Wireless Drivers".
Click the "+ Install New Driver" button and locate your .inf file you want to install. If it says you are connected and the LED light comes on your USB (you can faintly see the glowing led on the top of the USB) then your wi-fi adapter works! If not, try installing the second .inf file and you should be good to go!
