Playbase and BT smarthub 2

I have had a Sonos system for some years and all has been working well. I recently had to change my router as BT have moved me to digital voice. Since that move, my playbase keeps disappearing off the network. If I reboot the playbase it reconnects and works for a while then disappears again. I have no issues with other Sonos products, just the playbase.

I use a BT wholehome mesh network and the playbase connects to this wirelessly. It seems to connect using the 2.4 GHz channel. All the other Sonos products connect on the 5GHz channel.

The whole setup was reliable until the change of router to the smarthub 2.

Any suggestions as to what the cause might be?

In my experience the BT Whole Home WiFi mesh doesn’t forward SSDP discovery packets reliably between bands. If the phone is on the 5GHz band, the Playbase (which must use 2.4GHz) may disappear if it’s connected to a different mesh node from the phone. The choice of band for the backhaul can also be factor.

If you need a WiFi mesh I suggest replacing the BT one. The alternative would be to wire a Sonos component to the BT hub and use SonosNet for the speakers.

(BTW @controlav apparently hates all ISP routers, not just BT’s.)

They are the older disks, but the SSID is not the same as the router.

A long discussion with BT, they agreed it is their issue, but their tech staff have no more ability to configure the device than I have. Their proposed solution, replace my new router with the model I had before as I don’t need Digital Voice.
