Speaker and connection problems

Hi there, I repeatedly get issues with my devices not being able to connect to the speakers. I have 4 speakers set up around the house. Play 1, play 5, hard wired through connect AMP, and connected through a surround sound system. I have a router and and a booster. All was professionally installed, the issue is very frequent, almost every time I connect and is usually resolved with rebooting the router, but this can't be right. I also sometimes get speakers dropping off as well. Does anyone have any ideas what could be the issue here please?

Connection problems which appear suddenly are often caused by network problems, not Sonos problems. The typical cause is duplicate IP addresses. These often show up after an update or power outage because a reboot requires the device to request a new IP, and the router, having lost track of current IP assignments, issues a new IP that is in use by another device. Rebooting the router can temporarily seem to fix this, but as soon as IP leases begin to expire, the problem with duplicate IP's starts all over again. To permanently cure this, do the following:

Reboot/power cycle your devices in the following order:

Switches or hubs
Wired Sonos units
Wireless Sonos units
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.
Thanks jgatie, I think that sounds like sound advice. I'll try assigning individual IPs first and see if this works 🙂
