Hi! My T8210 doorbell camera no longer connects to its homebase for any length of time. The base is on the hall table and the doorbell is directly in front of it through the front window about 10m away on the outside of the iron gate. It used to work fine, but now it disconnects all the time, so often we don’t hear when someone is ringing the doorbell. Its really intolerable as this is its main purpose. Does anyone know why and is if it is a range issue, is there a range extender available?
