I think it does to an extent. But it’s not the best
Update #69:
Resetting my Sonos Playbar (specifically this device) is what fixed my issue. Apparently, my Playbar was using WiFi and Ethernet, even though I never setup my Sonos to use WiFi. Disconnecting the Playbar from Ethernet would cause my entire Sonos system to go offline (as expected, since nothing should have been connected to my WiFi). Resetting this device to ONLY use WiFi fixed my random network loop that Sonos somehow caused. I am still not 100% sure how that happened, since Sonos does not know my WiFi information, but I digress.
Issue is fixed, and I am happy again. Just waiting on the router now.

Sadly I have not fixed my issue.
It appears that it might be an ISP issue, but I have to “discover” the issue while it is happening for them to do anything about it. Oh well, life goes on.
SOLUTION:
The issue was a grounding block outside of my house that Xfinity replaced. Since they have replaced that, I have not had any issues with my network so far.
