Chime Pro (gen 1) dropping off network

My Ring Chime Pro (1st gen) keeps dropping off my network.The router is 3 feet away from the door to my hall. 6 feet down the hall is the Ring Chime Pro. It's plugged into an outlet I wired specifically for the Chime Pro, There's a range extender in the same electrical outlet. 10 feet further down the hall is the base station. RSSI -30The base station & Chime Pro have DHCP Reserved IP numbersI moved 2.4Ghz to channel 1It's still dropping. What do I need to look for?Do I need to start thinking about sub-netting my home network?Fred
