"Will not connect to the network" means that it cannot make any of the connections that are supposed to show up on the "Connections" tab. It will pretend it is trying to connect for a while, and then show the "Failed to connect" message at the bottom. That is the behavior I get when I use the "Communities" tab to connect. The other "Connect" button that's at the bottom doesn't seem to have any effect at all. All options/settings are unchanged at their defaults.
