I switched my home internet provider a couple months ago from Xfinity cable to Verizon Fios and my system has not been able to remain connected since then. I’ve researched every Fios-related help article here and have had multiple support calls with Sonos and have exhausted their ability to help me. The interesting aspect is I can reset my system (two amps on cat5 cables connected from an ethernet switch and about eight wireless Sonos devices) by turning off and then back on the power to the wired amps. Once the power is turned off and then back on to those wired amps, the system comes right back up but will only remain up for a couple hours and then I lose it again. So, the system does work when it is reset but then loses access … so it seems to clearly have something to do with the internet/wifi/router access.
I’ve tried changing every setting in my Verizon router’s settings that I think could be related or have been advised to switch/disable, including turning off the SON (self-organizing network) and renaming the 2.4 and 5 ghz wifi bands. Sonos support has also advised to turn on multi-cast (which isn’t a setting I can find in my router) and check the DHCP settings to verify if the max number of IPs on the router has been exceeded (which I can’t determine, but seems quite unlikely).
I’ve been through Corry P’s article here on common wifi issues but haven’t been able to identify any fixes with its help.
I’ll be grateful for any help the community can provide!
