Ok found the difference, and btw mine works now. I have ubuntu 15.10 installed and up to date. It picks up on the wireless card fine after the upgrade. If you do not want to upgrade to 15.10, i bet once you upgrade to 16.04 later this month you should see it working. The following shows that ubuntu knows mine is there:
