I have been dealing with this problem for a long time. I have had your service guys, and paid for it, out here to check my equipment and install. Of course nothing is wrong is the result. Now I am at the place of dropping your service for good for it is no good.
There are many reasons you could have slow speeds. Congestion on your beam could be one. Also if you have a lot of information of where you have been etc in your internet history. I clean my internet history before going off line.
Exede slows down, or correct me if I'm wrong, disconnects is more like it, when your data level exceeds your monthly allotment. Viasat really needs to stop this practice. More and more people are going to cancel their accounts because of the disconnects. I have a data cap on my phone, but when I go over my limit my phone does not stop working. It increases the buffering time on videos or slows up and downloads.
At this time I can't wait for FIOS to come into my neighborhood. Viasat is not responding to customer complaints about this issue. This is just an observation from my own experience. Sorry if I seem offensive, but this company needs to re-evaluate some tactics or soon they will be obsolete.
