I am following the advice of seasoned Ubuntu professionals and am posting my question here with a printout of a script posted by Wildman et al. I am grateful to you for your offer to help. Here is the link to the script output: http://pastebin.ubuntu.com/7706664/
I have tried numerous suggestions posted here on askubuntu.com. My device is not blacklisted. I can see it listed when I run lshw -C network

Any advice you can offer at this point would be greatly appreciated. I believe I have tried just about every suggestion on the forum. I got the ethernet connection working, and I feel I am close on the wireless connection, also.
