How do you reset wifi when new hub fitted

[Mickfen]

Hi I've had new hub fitted and can't connect my battery door bell to it.

Hi @Mickfen 

The easiest way to fix this is setup your new router/hub to have the same settings as your old wifi device.

If this is not possible you need to reset the Nest Doorbell.
