Ring pro going offline

hi, had my ring pro installed by an electrician yesterday. was able to set it up, but it then quickly dropped offline. I have followed all the steps in the help topic - resetting wifi, checking wifi connection etc and it will reconnect if i enter set up but then goes offline again. the status says good wifi/power supply. i have noticed a slight buzz from the mains fuse box which disappears if i turn off the ring fuse. Any suggestions?

Hey @shaun84. How do you have the Pro Power Kit set up with your Doorbell Pro, could you take a picture of what the wiring looks like? In addition, what kind of internal chime kit are you using?
