Sorry for double posting, but that last one was 5 days ago and this, i think, is very important for anyone who may need it.
what i did in my last post DID WORK, but i didn't check the available wireless networks after running
and they were there!! ready to be selected! and i got my connection with no more problems! so the answer for the question of this thread is YES, The NETGEAR WNA1100 USB WIRELESS ADAPTER does work with ubuntu (with the mentioned driver). but i got another problem later. The problem is described perfectly on this thread first post, and it has its solution!
sudo modprobe ndiswrapper
well if someone out there still has problems with this adapter feel free to post, but i think this is solved!.
