You cannot connect to the network but all your hardware seems to be functioning fine.  You can try pinging your network card to make sure it is functioning by pining local host.  At the prompt type in “ping 127.0.0.1″ Without the quotes.  If you receive a reply 4 times you’re good to go.  If not, then you will want to investigate your NIC (Network Identification Card).
