Anyone else having a problem with AT&T Uverse Gigapower and Sonos? They use the PACE 5268ac gateway/router from Arris. The Sonos will work but it seems that the Sonos might be taking the whole network down every 2 to 3 days. Basically, things will be working normally for a few days and after a few days, everything stops working and the only fix is to reboot the Pace router.
I have many Sonos devices - a few Play5's, two Playbar's, a sub, some Play3s and am Amp. I use the old Sonos Bridge for Sonosnet and the Bridge is directly connected to the Pace gateway/router.
I looked up the specs of the Pace router and there is no indication that the router supports spanning tree protocol (STP). https://www.arris.com/globalassets/resources/data-sheets/5268ac.pdf
Does anyone know if I'm looking in the right place as I troubleshoot the problem? Are there any workarounds?
I'm planning on connecting a few more of the Sonos devices via Ethernet - specifically the Amp and one of the Playbar. I can likely also connect a couple of other Sonos devices - in particular a Play5. But since the Pace router is at the center of the network, will connecting more Sonos devices via Ethernet make things better or worse?

So, after some trial and error and reading a lot on this forum, I determined that my Sonos system was erroneously connected BOTH via the Boost AND the “Standard" way via my home wifi network (as opposed to only the Boost mesh network or only my home wifi network). I then thought that using both methods to connect the same devices into the network might be the cause of the network freezing up. So I “reset” or disabled my wifi connection (via phone app: Settings -> Advanced -> Wireless -> Reset) and then reinstalled my Boost directly into the network via Ethernet. After doing this 24 hours ago these actions have resulted in a smooth network with no freezes so far.
If my actions end up fixing the issue more permanently than the 24 hours so far, then you may want to confirm that your connectivity is Ethernet wired via BOOST (or wiring any one Sonos device directly to the router) OR is not Ethernet wired and via your wireless network, but not both (and if wired via Boost the setup is not done the app’s wireless setup tool). Below is more info on switching between Boost and Standard setups and visa versa. I hope this is helpful!
