That's strange. I don't see any reason why AutoDisconnect could lead to that. The only reason AutoDisconnect might cause problem while connecting is the new BETA functionnality in v0.4 "Use 2G when not connected". Just disabling the option (which is by default disabled) will correct the problem. If it happens again, post on this thread the content of the log file /var/log/autodisconnect.log.
