Google Fiber router dropping Sonos devices

Go to the router’s DHCP Settings page, assign all Sonos a static/reserved IP address.

Power down all Sonos, power down the router and extensions.

Power the router back up, wait a couple minutes then power up your Sonos, any wired ones first.

A lot of folks see issues with DHCP’s normal random IP address assignment process.

Thanks Stanley. Giving it a try. Fingers crossed. 

Where can I find the routers DHCP settings page? What is that? Is it an internet page or something? 

You'll need to read through the router's documentation. Usually this is available online. The keywords to look for would be ‘Reserve' or ‘Fix' IP addresses. Most, but not all, routers support this.

For me, I had to go to the Google Home app > WiFi > network settings > advanced networking > DHCP IP reservations. Then add the devices. Just pick any number for the last digits of the IP address. Make sure to save. 
 

Worked for me 🙂

Well, not ANY number. It needs to be one that isn’t already assigned to a device connected to the router. It’s unlikely out of 254 numbers you’d pick an existing one but if you do, that existing device and the Sonos speaker will be in constant conflict…

Good to know. I think I was lucky 😀

Thanks 

IP addresses are “leased” for a period, typically 24 hours. A client must return to the DHCP server and “renew” its lease at this time. 

Best thing to do is to assign the DHCP range to issue leases only from .50 to .254, and assign any static leases to values between .5 to .49… That way you are guaranteed to avoid any IP conflicts.

Some older devices do not use DHCP, never lease anything, and simply use an address. These devices should be assigned addresses outside the DHCP managed range. SONOS devices use DHCP.
