Effect of Internet Service Quality on Streaming?

Occam’s razor time.

@nyev you’ve appear to have spent a lot of money and time on everything but a new router and good Ethernet cable. Dump the router from your ISP as they are worthless. Also, change out whatever Ethernet cable you’re using to Cat-8. As cheap as Cat-6e but super shielded. Check Amazon.

You’ve also mentioned that your problem occurs in the late afternoon, after your kids get home and hit the internet. Sounds like the crappy ISP router can’t take the load and is dropping out (high chance one of your internal connections is bad and causing excessive packet retries which drag down a cheap router). Also the cheap routers don’t have any sizable ring buffers so they can’t queue things up well.

Remember that 4k video requires 34Mb of bandwidth.  Add on whatever else you’ve got streaming (phones (cellular using WiFi and VoIP), internet streamers/radios, television, etc. and you’re probably using 50-74Mb bandwidth easy. Bet the router you have came from when you had 100Mb or less internet. 

I recently attended a demo of Shunyata Altaira $3k. This works to correct

noise caused by poor grounding. No idea what your issue is but I will

say that demo provided the best sound I have ever heard. Go Shunyata!!

Thanks All - New Router, CAT-8 Cables, Grounding Boxes, and THC - Got It!

These are all great ideas that will likely improve sound quality (esp THC - what is that, “Total Harmonic Control” or something?  Sounds promising.

But none of these will fix the dips in quality, which in case you haven’t read my post above, I agree with everyone that has said it’s not my network.  Because, playing an equivalent local file is also bad when quality is bad.

That leaves noisy AC power and RF as likely culprits, but probably AC.  And as above I’ve tried many conditioners and isolation transformers.  It may be that my only solution is a Stromtank, one day down the road.

@nyev If you play an equivalent local file at the same time you have bad internet quality and it’s bad too, then it’s definitely something internal. Whatever’s causing it will be between the source and the receiver.

In normal circumstances if your source and receiver are both connected to the same Enet switch then you’d troubleshoot by swapping ports, that is moving the devices to a new port, one at a time, and seeing if the problem clears up, because ports on switches can go bad. However, you may have a problem with doing this if both the server and receiver are on your Innuos switch as it’s only got 3 ports. In that case you’d swap in a temporary switch to see if the problem clears up.

I then ask, since it appears that you have more devices then the 3 on the Innuos, what are you using in front of it as your main switch, how is it connected in circuit, and are your server/receiver both on the Innuos?

I have observed degraded streaming from time to time. I have a well isolated setup with 2 of the Jcat M12 switches cascaded into an Uptone Ether Regen w sfp to my server. 
While I do not see the daily fluctuations I do notice a degradation over time and found that a hard reboot of my router gets the sound back to where it should be. 

The scripted  "Perform a hard reset" is what they always say to do when we call for internet problems, even though it usually has nothing to do with service being out.
From what the internet people say, the reset will reset the connection on their end as well and there is a whole host of things that they are doing in the background that can effect the network connection. We were being throttled frequently and once we were told that there was more than 1 person on out IP address. 

Who knows what is really going on on the provider side however for me I will reset the connection at least once a week.
