I'm finding if I run a continuous ping with (Ping -t 126.96.36.199), I can see most of the pings for me are in the 600-700ms range.
The few times I needed to get into my PC from a remote location I've had to use GoToMyPC.com which works but it's awfully slow. And I'll get frequent status messages from GotoMyPC that the connection has timed out and I have to wait and it'll start working again.. Which means to be the upstream is nowhere near the 2Mbps that they claim for the PowerMax plan.
I never had this problem with Exede12...
Maybe in 5 years highspeed satellite broadband might work, but by then I think 4G/LTE will have them beat in coverage... Maybe..
600-700ms is quite impressive for satellite. Theoretically (meaning in a lab environment) the lowest latency possible to a satellite in geo sync orbit is about 436ms round trip. Then you have to add the latency between the Hughes datacenter and which ever 188.8.131.52 anycast server you are pinging.
