I am running on the VIVID 200 broadband service, with a Superhub 2ac running in Router mode. I have been trying to operate more than 2 Ethernet ports on the device for about a week now, but when I try to activate service by plugging into a third Ethernet port, all three Ethernet ports go "haywire" and stop functioning correctly (kick-off the services running on the ports) !! It does not seem to matter which of the 4 Ethernet Ports I use, but any two work fine, then when I plug-in the third the trouble begins immediately. Can anyone help please ?? I'm thinking maybe I need the Superhub 3.0 these days, because our VM broadband traffic has increased a lot since we began with VM two years ago.
