wireless

After upgrading 12.04 LTS, my wired connection works but no wireless connection found. I tried many suggestion for wireless connection on Ubuntu forum but nothing works for me.

Now, maybe by mistake, I am also unable to connect Internet through wired connection.

Now,
(1) its says "No network devices available" and
(2) in System Settings ? Hardware ? no additional driver icon is showing

Please help. I don't know much about Ubuntu.
