I just updated to Ubuntu Studio 13.04 and I now can't access wireless networks. Network Connections shows the connections are there, and recognizes the internal modem, but just won't connect. On the wireless menu, it shows "disconnected" and it's grayed out. I actually don't see anything in the menu that gives me the option to connect to the wireless network. I tried deleting and rebuilding the connection to the wireless network, but still no results. I'm tempted to do a clean install of 13.04, but want to see if I have other options first.
