internet connection dropping with Eero modem in bridge mode

I have installed an Eero mesh system and I'm experiencing internet drop-outs constantly. I have put the modem in bridge mode, disabled the internet hotspot (as was suggested in another forum) and recycled the modem and Eero routers several times. Is there any other setting I need to change to stop the dropouts? This is primarily affecting my work VPN and is very annoying.
