Connected but can't connect to anything
My partner is running Kubuntu 12.04 (as I also am) on a laptop with a wireless connection. The networking icon on the bottom row indicates that her laptop is, indeed, connected, as does System Settings / Network Connections / Wireless. Nevertheless, she isn't able to connect to anything, either through Firefox or by pinging. What might account for that? I'm trying to talk her through this over the phone.
