Please see attached image.

I am experiencing 20-30 disconnects a day, averaging 3-5 seconds for the last month and I have not changed any of my network setup. I have had a very difficult time diagnosing the issue. The disconnects usually happen in clusters, I have had clusters of disconnects during the day when the PC is idle as well as when I am playing video games.

Does this image confirm that the issue is in my LAN? Between my router and my PC?

Could my PC be the issue? or is the router or Ethernet wiring?

Any help is enormously appreciated.
