I am sorry you are having problems with rubber banding it can be most frustrating. I would say the biggest way to help is to make sure you are using a wired connection for gaming and not wireless. Apart from that the area traffic and performance are looking good so it does not look to be that. The only other thing that may cause an issue is the hub upstream power levels are too high:-
VM SUPER HUB 2AC Upstream 0 55.3 dBmV
VM SUPER HUB 2AC Upstream 1 55.3 dBmV
Probably best to let one of our engineers take a look please. I will send you a forum private message to arrange an appointment.
