I have Ubuntu 9.10 and I experience the same problem. When I reboot it works fine but sometimes it disconnects with no obvious reason and then it asks for a password. Sometimes I choose to right click-> disconnect and then connect again but this doesn't always work. Maybe later I'll provide some more info. Until then, it would help me if somebody provided some specific commands I should give to get the needed info related to the problem on my computer.
