Effect of Internet Service Quality on Streaming?

@nyev There’s an old saying, "Madness takes it toll; please have exact change." Feel for you. I have gone through a months’ long house internet bugaboo that was h e double hockey sticks to sort out.

Is streamer hard wired?

It does seem like power is the bandit but is it something in your network? Given the excellence of your equipment, I imagine you have enterprise level or better stuff up stream of your streamer.

Have you asked, bribed or manacled your kids and others to cease web activity during the sound downturn times? This could be a revealing test. When there are problems the network pros always isolated it one part a time and build back in (I made this up but it sounds official). Run your system and then add back one other things, one at a time.

A few more pot shot thoughts. Have you swapped out power supply cables? Is something in the jumble of cables too close to something else?

Thanks for the ideas All. My sound has not experienced a SIGNIFICANT dip in quality since Friday evening so I’ve not yet had the chance to test streamed vs local file during a “bad” period.

To answer a few questions that have come up:

• No I don’t have a dedicated network line to my Innuos Zenith Mk3 streamer. I do have the Innuos PhoenixNET switch in front of my streamer/server.
• During the bad periods before I’ve had family members stop their internet usage in the house and it didn’t improve things noticeably
• I’ve upgraded power cables a number of times (have Audioquest Dragons now) and the major quality swings remain
• I’ve tried several conditioners including the AQ Niagara 5000, a Shunyata Hydra, a Puritan PSM156, and also a Torus RM 20 isolation transformer and they all had equal swings in quality. None were any better than the other in this front so I highly doubt a different conditioner is the answer. Also sceptical that a PS Audio regenerator would produce better results, but I’d be open to that possibility. Not my first place to look to fix but something in the back of my mind.
• Ahead of my Innuos PhoenixNET switch I just have the fiber modem from my ISP, feeding a the wifi router from my ISP which feeds an inexpensive D-Link switch in a smart panel (should I upgrade this???), with 60ft of generic new network cable going through my wall that eventually feeds my Innuos network switch. Maybe there is a problem here???
• I need to update my system listed on Audiogon - I now have a Tambaqui DAC, the Innuos Zenith Mk3 and PhoenixUSB reclocker (no Grimm MU1 anymore), I have a Puritan PSM156 now, and I’ve upgraded my my speakers to Audiovector R6 Arrete’s. Also have upgraded all power cords to Audioquest Dragons.

@nyev how many neighbors have electric cars? 

Ok, so not the real obvious stuff. You have a challenge. Given what you have tried sounds like your logically taking apart the problem… logic will eventually succeed. I’m looking forward to hearing what successfully solves this.

My digital streaming further improved and stabilized by using a high quality 50FT CAT8 LAN (LinkUp from Amazon) between my Infinity Modem ➡️ SoTM iSO-CAT7 ➡️ Telegartner switch. The LinkUp cable replaced a pair of mesh network pods. I have also upgraded to 1Gb/s speed.
