Virgin Fibre WiFi 6 Hub 5

I have just taken Virgin Fibre 130+Mb connection.  The ring wired doorbell now shows a poor connection. I was on standard copper 11Mb before and was working fine. Does anybody know if my model of doorbell is compatible with Wifi6? Router is within 3 Meters.  Router has 2.4GHz and 5 GHz enabled.  All other devices in the house are running great. Any ideas on how to resolve or is the doorbell too old? Have tried reactivating but still poor signal.
