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.

I will admit his jitter does seam high even for sat internet...if jitter really was that bad they couldn't offer voice services

They offer it, just like they offer Direct TV service.... as a 3rd party.

I would wonder if there was another problem going on.We typically get similar numbers to what you show, yet we actually have been impressed with how smoothly video runs when we have streamed one on occasion.  Twice when there was extra data left at the end of a period we streamed a live basketball game on Exede and it actually worked better on Exede than it typically did on our Verizon data.   Maybe one of the reps here on the board could help trouble shoot your equipment and make sure there isn't something else wrong.  I agree, very frustrating to be just out of reach of a WISP provider.  I am back up to our other farm this week again and when there I stream a lot of Netflix and they run between 3 mbps and 5 mbps but the ping is usually around 50 to 60 there on that connection but like you said it works great on their connections.

Yes, thank you. One rep said to pause it. But on Flash Player it doesn't help. It works on 'most' you tube videos as it continues to load when paused.

Ricky, YouTube now uses a somewhat annoying playback method called DASH. It makes videos load in chunks so there isn't a way to let the whole thing load before watching. I use a browser plugin/script called YouTube Center to disable DASH and it works great.

YouTube did some recent changes that broke the plugin, so you have to use the Developer Version, but I haven't had any problems with it. You can get it here: https://github.com/YePpHa/YouTubeCenter/wiki/Developer-Version

You can also use YouTube Center to force videos to always play at 420p by default, etc. It has lots of great options. Just look for Disable DASH Playback in both the Internal and External player pages within the YouTube Center settings and select it.

I noticed lately that not ALL videos keep buffering when paused...I didn't  know why, that is why I said 'most' in my post. Thanks, will look into it.

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.

Ricky, all of those stats are within acceptable levels. I've run the same test a few times internally on our test system and got very similar results.

Thanks for all the replies. Thanks to OLD LABS for explaining 'exactly' what jitter and latency means with that graphic. Let me state unequivocally, I AM NOT AN EXPERT. I wouldn't even classify my self as an experienced user. I am just a user who has an experience/problem. 
 I haven't tested my VOIPs that I own yet. Speed isn't everything as I explained in my original statement. For speed runners say for the 100m race there are at least 4 'world' records....Inside track and outdoor track. [ also male and female ]. 
So, as stated some above....Latency is improbable to overcome and Jitter is the subset of it. So, how do we get around it for the moment? Delaying or buffering, in my NONEXPERT opinion is one answer. Watching live reports on the world news, you'll notice a reporter will stand there for 2-6 seconds when asked a question before they respond. Also, there's a delay between a watching satellite/cable thru a box vs an antenna or even a different box in another room.
You can pause 'most' youtube (and the like ) videos and you will see the buffer bar keep moving. It doesn't happen with Flash on the computer. Will this also work for VOIP? 
Because of 'shock-jocks', it is rare that you hear (or even see the lips) of an 'inappropiate' word coming across your TV set these days.

Start the video and let it play, switch to another tab while it starts playing and buffering; go back later and drag the the slider to the beginning and replay - if you wait long enough, the remainder will continue to buffer and be done before you get there. Works for most of them and I used to do it all the time when on Wildblue and a whopping 512Kbps connection (most of the time much lower and even when I was on dial-up).
