Effect of Internet Service Quality on Streaming?

A significant amount of RF penetrates through the equipment chassis itself.  A significant amount enters through vinyl.

Neither of these paths can be managed with a power line filter.  Its up to the manufacturer of the equipment to create a power supply that filters the RF before penetrating the power supply.  But, a over filtered power supply can sound flat and lifeless.  This is especially true with a phono preamp.

I tried the puritan ground box.  It did nothing in my system.  But the dealer that sent it to me doesn't even use it.  He uses CAD.  What I am saying is a good ground box may help.  But your going to need at least 2.  One for chassis and one for signal.  Then you need a bunch of cables.  A good ground box solution is generally around $7k to $15K in equipment.

Erik, I note your comment that you can increase the buffer size for Roon.  Can you point me in that direction?  I had lots of issues with HiRes over a mesh network. The system is now wired but I still occasionally have stoppages that i suspect are related to buffering.    Thanks, Mike

Thanks All, lots of ideas and as I mentioned I’ve been dealing with this issue for a few years now, with numerous changes to my system during that period.

Lots of great ideas to improve my upstream network to consider. That said, while these ideas may improve my system, I am doubtful they will resolve my occasional extreme quality dips. Because, like others have said in this thread, I think it must be a power issue as opposed to network. I started this thread hoping maybe I did have a network issue as I think that sort of issue would have a better shot at being solvable.

I’ve experienced a few dips since starting this thread, but not as extreme as last Friday evening. During the recent dips, I did try to see if the gap between the local and streamed file widened, but it did not - they both seemed slightly degraded which again points to power - or possibly RF noise - being the culprit…

Maybe grounding boxes will help, but that would be an expensive shot in the dark to hope it’s the solution! I’ll keep trying things.

@nyev I don’t see anything in recent posts as to whether you’ve gone back to your ISP to have your ONT checked. That’s the converter to change fiber to either coax or RJ45. Fiber itself doesn’t use a modem,

Your previous post said that you’re using the ISP provided fiber modem and wifi router. Is the modem truly a fiber to RJ45 or coax to RJ45 connection? If it’s coax to RJ45 then get the ISP to get you a connection into your house that’s an RJ45 ethernet connection (they can do this if the outside connection is an ONT panel that’s a Motorola or Calix which they can set to provide both). The problem with the coax is that it’s usually using the old RG6/RG11 that’s interconnecting throughout your house through a number of splitters. The ISPs usually like doing this because it means that they don’t have to rewire your house when they put the fiber in.

As far as the ISP provided router is concerned, dump it and get something decent. The ones provided by the ISPs are usually cheap (for them) Arris or Actiontechs that probably cost them about $2 each. Go buy a decent wifi router such as a Netgear Nighthawk X5400 or TP-Link Archer X5400 or a mesh system such as Netgear Orbi, Eero Pro6, or TP-Link Deco. You’ll probably find that this is where your problem was. I’m surprised that with all the money you’ve spent on filters, conditioners, and the like that you didn’t do this first.
