I have been using Ubuntu for a year and a half. Since Hardy Heron. When I installed it my wireless worked immediately and never had a flaw. I have always updated when the alerts came along. The last update was one that completely changed my desktop and the way things work. I am getting used to a lot of it but my wireless stopped working. A box opens up and asks for authentication. I fill in the password and after a second or two a box appears that says connection established. After about 5 seconds the connection is lost and the authentication box opens again. I have been trying to login for days. I have restarted several times with no change. The new operating system is Ubuntu 12.0 4 LTS. My computer knowlege is very limited. Chances are if you ask a question it will be necessary to instruct me how to find it on the computer.
