You may have a device interfering, or maybe there is another WiFi transmitter nearby on same channel that is not always on. Hence the suggestion to use a phone app to measure and also check at different times of the day.
Not sure why you are reluctant to get a power board to test PLC? PLC is stable and sounds better than WiFi.
