Hi @Mark_gh. To clarify, are you saying that there is a wall between your router and your Doorbell? It’s worth noting that while distance does impact the signal strength with wifi, if there is a wall between the Doorbell and router this can also impact it as different building materials can cause different levels of interference. You can find some more information on how to improve wifi signals in our Help Center Article here. It’s also important to check the RSSI on your Doorbell to see what that is indicating. I hope this information is helpful.
