Just this past week I started trying to work with Connect. Typically my (wireless) cable connection is running between 25 and 30Mbps. Sometimes my connection speed will drop (the speed changes are external and not related to the connection being wireless). One day I was having a lot of VST Connect droputs, checked my speed, and found my speed had dropped to 4 or 5Mbps.
With my wireless setup, 2Mbps would not be fast enough. Could be different with your hard wired connection.
