Ring doorbell keeps going offline since WiFi change

I have a battery-powered ring doorbell (doorbell 2 I think) that has recently had issues with connection to my WiFi and the chime pro network. I recently changed from an Orbi mesh to eero, due to issues with Orbi. All my devices connected to the eero network fine at first but lately I’ve had problems with my Ring doorbell. Normally it’s connected as follows: Wifi —— Chime pro — Doorbell However this connection (which worked fine for years) started just dropping the connection despite no changes. I tried to connect directly to the WiFi with the doorbell and get similar issues: fine for a while then goes offline. Internet/wifi connection from the door next to the doorbell is fine, WiFi strength seems ok for doorbell and chime in the app
