connect wifi issues

I’ve had my Sonos connect and play 1 for years with no issues on Virgin broadband. I’ve just had a new router that looks identical to the old one but it can’t detect on Wi-Fi. It will play with an Ethernet connection but still can’t find  the Sonos to update the Wi-Fi. As soon as the ethernet cable is unplugged, it loses connection (obviously). 
 

Anyone else had this problem? Might it be different software in the replacement router..

Alas this hasn’t worked. Found my connect when connected via Ethernet. Finds it on the app but not on system. Can’t fond my play 1 speaker at all 

Have you followed the guide for setting up a Play:1 on a new wifi network? (Hint: it involves a factory reset and fresh setup as if it’s a new speaker.)

If the SSID and password have changed with the new router, then older devices require a factory reset to join a new Wi-Fi network.

If you can’t change the SSID/password to match what was used previously, factory reset the device that is not wired to the router first, then factory reset the other device so you don’t lose any Sonos playlists, favourites etc.

It is possible some other settings differ between the two routers, check if the above doesn't work.

looks like this is the relevant bit though it might as well be in Chinese for me 😂

Your Play:1 is still trying to connect using the network of the old router. The Play:1 will show in the app if you connect it by ethernet, but to use wirelessly on a different network you will need to factory reset it.
