My server kept throwing network errors, and I literally spent hours blaming everything else and trying to get it to work. I looked at the cable. The link light was on, the connection was up, and nothing about that patch cord looked wrong. We treat a cable as either working or dead, but there's a lot of room in between where things limp along and cost you speed. When I took my storage out, the Ethernet cord popped off. It was broken, and I had no idea.
