HikVision “Network is unstable” problem

Hi all,

hope every one is keeping well in these difficult times. A newbie here with a bewildering problem.

I have a dome camera as one of 8 networked to my NVR. This camera was working perfectly for a couple of years until a week or so ago when it comes up with “Network is unstable” and shows no picture. I checked the recordings and again nothing recorded for a week. I tried via the browser based GUI as well as the HikVision iPad app.

Now, doing some diagnosis I tested the Cat 6 cable...
