Video Doorbell Wired Motions not being detected

I have had a video doorbell wired for about three months and it has worked perfectly all this time. A couple of days ago I noticed it wasn't detecting or recording motion on my driveway, it detects motion on my front lawn and front path. I had made no changes to settings prior to this happening. Since I noticed I have deleted and re added the motion zones numerous time, I had one zone covering the whole area and two zones overlapping but it still isn't working. I've also rebooted the doorbell (not factory reset) via the app. Firmware is up to date. I have read that a poor RSSI can cause performance issues, mine - 63. Is there anything else I can try before I look at a WiFi extender? Thanks, Paul
