If you have suggestions I will look into them.
Power outages that cause Sonos problems are almost always due to network problems, specifically IP conflicts. These often show up after a power outage because a reboot requires the device to request a new IP, and the router, having lost track of prior IP assignments, issues a new IP that is in use by another device. To cure this, do the following:
Reboot/power cycle your devices in the following order:
Modem
Router
Switches or hubs
Wired Sonos units
Wireless Sonos units
Computers/printers
Wireless devices - phones/tablets etc.
Allow each device to come back up before proceeding to the next. Note that you can permanently prevent duplicate IP addresses by assigning an IP to each device's MAC address in the router setup. See your router manual for details.
