Hi @Jim R.

Welcome, thank you for reaching out to Sonos Community, We appreciate your time and effort in posting your concern here in our community.

I'm a little bit confused about the issue your having.

Can you please give us more details on what's going on with your Sonos app.?

Make sure you're using the right email address in your Sonos application.

If this is to transfer your Sonos system to a new account click here.

Let us know if it works. If you need help with any other information, please be sure to let us know.

It’s not a new account

It’s not the internet or the date

Hi @Jim R.

Welcome, thank you for reaching back to Sonos Community.

Here are router settings that need to be verified. You can contact your ISP or the manufacturer of the router for assistance.

a. Auto channel must be set to Off

b. Choose best non-overlapping channel (1,6,11)

c. Set channel bandwidth to 20MHz

d. Both 2.4GHz and 5GHz should be enabled

e. 802.11 band should be set to b/g/n

f. Airtime Fairness should be disabled

after you verified the router settings I’d also be tempted to do a network refresh, by unplugging all Sonos devices, then rebooting the router. When the router comes back up, plug back in the Sonos devices.

If you can hardwire one of the smaller speaker directly to the router much better to set it up easily. 

Let us know if it works. If you need help with any other information, please be sure to let us know.
