WooHoo....I am NOW at the Public Library replying on their wireless connection whilst on Lubuntu 12.04!!! :-) Thank you SO MUCH to ALL who helped!!! I hope this works when I get home tonight on my network. I have NO IDEA WHAT you guys did or what any of those codes I put into Terminal meant, but I hope ONE day maybe I will have SOME idea!!
Thank you again to ALL!!!!
