Unstable system

I tried changing my Xfinity channel but was unable to get in. Comcast was unable to help over the phone and is sending a tech on Saturday.

Is there anything else I should seek help with from the Comcast tech? Maybe set up static iP addresses for all of the Sonos devices?

Don’t worry about the matrix, maybe show it to the tech person when s/he pops in as they might be able to suggest things to try when they see your Home setup.

Yes, I would ask him/her to kindly reserve all your Sonos products IP addresses in your routers DHCP reservation table and when they’ve finished sorting things out, ask them to backup/export your router settings/configuration, that’s if the router supports that feature. Then, if you ever have to factory reset the router at any point, you can quickly import the settings back to the configuration that the tech person thinks should work best for your current network.

Hope all gets sorted for you.👍

This forum software isn’t very fancy so a lot of stuff that works elsewhere isn’t supported here.

Try uploading (the paperclip icon) your PDF as a file, it should show a note below the post that it had been uploaded. Folks (or you) should be able to view it from your post.

Comcast tech came and I was able to log in to my router. Unfortunately, the option to control the 2.5 choice of manual or auto was greyed out and couldn’t be switched to manual. Also greyed out was the channel selection box. So no changes for this function/area could be implemented.

‘The tech called his supervisor. She was sympathetic and said she would escalate the situation to an engineer to see if a resolution could be implemented.

She said she had never encountered this scenario before. In listening to my goals, she offered one more potential fix: to get a “sub router” with its own IP address. And my Sonos products would feed off of this “sub router” (my term). If I am describing this potential fix correctly, is it worthwhile to pursue it? (Goal being to reduce interference and gain system stability.)

I’m surprised they are suggesting to use a different router in place of their own - not that much confidence in their own supplied product? At the very least they should help establish what channels are in use, so you then know which is the best SonosNet channel to use. Did they do anything to resolve the interference around the Front Bedroom Sonos One and any other relevant devices seen in your matrix?

I would let them escalate the matter and try to resolve it that way, as long as the system is usable at the moment and see what they can do to find a solution for you before switching to another router. It’s a matter for you, of course. I was hoping a ‘tech’-on-site would have been able to sort these things.

Unless you can disable the WiFi in the primary router you won’t gain a lot with a second router.

Even better if your primary router offers “Bridge Mode” where it disables WiFi and routing and only uses the modem functions.

I’ve made some progress with two added routers - one each on the upper and the lower floor.

The system is more stable now by far. The matrix shows the speakers handling any interference well.

Thanks for the helpful suggestions!

latest issue is with amps hooked to speakers. They work for a while and them the amp goes blank.

I’ve found a fairly good tech - the guy that installed the routers. I’ll see if he has ideas to get the amps stable, or I’ll be back here.

Happy Thanksgiving!
