Most of us complain about dats allocation vs price.
Also, not rolling over data. My latest complaint also included having to purchase a "Wireless" modem with a hub and finding out that the $10+ rental fee is just an add on expense....doesn't 'cover' the modem under normal use or unforeseen disasters.
Further having no wireless access points and jittery streaming video. If I was 'close' enough to the tower of my previous ISP, I could watch a video at 3+ Mbps. But it was wireless and depended upon the making the connection. Further, if like me, you're an antennae user....you can't watch 'next' day programs with certain network TV stations; unless you belong to an 'authorized' satellite/cable provider...which Exede is not. 
So now, my problem is streaming video. It's jerky. As most streams count on Adobe...it doesn't buffer for fear of being able to be copied ( I assume). I am not an expert...but this is my assumption
  The problem with congestion is not only the speed and the data limits...upload and download speeds are not "TRUE" when it looses packets and takes forever to get there and back. Most troubling to me is the ping, latency and jitter is the biggest problem. Ex. if you set your cruise control @ 100 mph on say the I5 in California...going up hill, around a bend facing a wind you'll be lucky to get 35mph on the odometer. Try megapath's speed test and you'll 'really' notice the problem,

There should never be a packet loss...but latency and jitter are way off range for optimal performance.

Without rewriting the laws of physics and mathematics (perhaps the FCC will attempt that too), latency is inherent to all satellite communications:



ViaSat-1 is located at 115.1 degrees west on the equator some 2000+ miles west of Equador.

Under the best of circumstances the round trip will be about a half second -  that's assuming your directly under the satellite along the equator (apparently on a boat) and in a vacuum (the speed of light is around 186000 miles per second in a vacuum).

Naturally most of us don't live along the equator and the round trip can be greater dependent upon your latitude and longitude (Pythagoras says so) and right off the bat you're looking at somewhere around 575ms latency under the best of circumstances.

Similarly, none of us live in vacuum and other factors impact latency: bandwidth saturation or congestion, number of hops, and inherent network latency.

Jitter as described here is simply the variance experienced in measuring latency, and the above is simply saying you experienced an average latency of 799ms +/- 21ms for that specific speed test. Similarly, you experience the average upload/download speeds shown - in both cases, sometimes higher and sometimes lower during the speed test. Jitter as described here is not the primary cause of 'jittery' or choppy playback.     

Pretty typical results for satellite internet.

As to whether the video actually buffers or not that's dependent on the sender as well as current network conditions - most that I encounter definitely buffer in advance providing smooth playback but during peak usage periods they frequently exhibit some choppy playback due to bandwidth saturation.

My apologies in advance to the physicists and mathematicians in the audience for the layman's explanation...

Old Labs - I really don't think it is fair that those living closer to the satellite's location get faster propagation times.  A few milli-seconds may not seem like much, but it adds up you know.  We all need to write whitehouse.gov and see if we can get the 100,000 signatures to force the FCC to address this geo-centrist discrimination.

If not for those pesky velociraptors, I'd consider a move to Isla Nublar.
