We are in a "holler" up in wine country all of 50-60 miles from downtown San Francisco, and we might as well be in a Himalayan valley. We had Hughes.net for years, and when they announced their new GenX a couple of years ago we upgraded and went to the middle level of service and speed. That helped a little but any satellite service has lag time issues due to the signal needing to round-trip to a satellite. Some web sites were worse than others, and BPN, for whatever reason, was one we had the most trouble with.
I suspect lag time is your issue, frustrating as that may be. Maybe Peter Kes could be of some help. I'll check with him.
