Streaming Video Constant Buffering

I know this has been addressed in a variety of previous posts but I haven’t really seen a good explanation. Using Netflix or Amazon Prime in the evenings, the stream stops to buffer every few minutes....

    I am considering setting up a home network PC based server that possibly could be used as the recording device and then fed to my Smart TV thru an Ethernet connection.  

    If your smart TV or some other connected media device, such as a Blu Ray player, has a USB port, you may be able to watch the downloaded items via USB flash drive or external HDD/SSD as well.  This is what I do.  I've got all of my PlayOn Cloud files written to a 1TB external SSD.  Though I dind't know it until I tried, my smart TV has a built in file playing app which plays the .mp4 format of the PlayOn Cloud files, as does my Blu Ray player. 

     

    I also write the files to DVDs and/or Blu Rays for more permanent storage.

Unfortunately, with your overall speed being adequate, it's not likely that there's much that can be done, as the primary cause is almost assuredly the combination of the high latency and system congestion, the former of which is inherent to geostationary satellite internet, and the latter of which is due to high system usage.  

 

Though there is no guarantee that this will help, one thing more you can try is either rebooting or power cycling your HughesNet modem.

 

--- To reboot the modem, go to this modem page and click Reboot near the top.  If you're connected via WiFi you'll likely temporarily lose your connection while the modem is rebooting.  After the reboot, it would be best to wait a few minutes to try your activity again.  This gives the modem time to be fully back up and ready. 

 

--- To power cycle the modem, which is like a reboot, but a bit more extensive, unplug the HughesNet modem from the power outlet, wait for at least 30 seconds, then plug it back in.  After waiting for at least five minutes, try your activity again.  When power cycling the modem, it may also be best to first turn off your connected devices, then turn them back on after the five minute wait period.  

 

What the above can do is set your connection a different "channel", at least temporarily, and this new "channel" can sometimes be cleaner, so to speak.  If it is, you may experience less buffering.  As alluded to, though, the effect may only be temporary, as the channel you're assigned to at the time can fill back up with more people and/or dynamically change.  For reference, the "channel" I'm referring to is the last four digits of your "IPGW Gateway Association State" string, seen here.  

 

On mine....

 

  

 

Again, there's no guarantee with this, but it may be worth a try.

Just to be clear: Congestion causes latency in addition to the inherent kind (~5-600mS due to the round trip distance the signal takes on satellite) as the system plays 'catch-up' to service the demand. There is also some long-delay weirdness in the order of 1-minute gaps taking place on the internet backbone that it outside of HughesNet's control, which doesn't help the matter.

 

The streaming protocol requires a lot of handshaking with the streaming server. Under severe latency conditions, it often gets delayed past what the server expects and times out. The default result is to force a 'buffering' display until it finally re-syncs.

 

Bottom line: When you see buffering, 9 times out of 10 it's latency and nothing to do with speed.
