Question How to use a new cable tester?

[axlrose]

This feels like where I need to cable test. Can anyone help me with now to use this cable tester to find if there is anything wrong with any of my runs now that I have replaced the small flat patch cables with solid ones from Monoprice and found the problem persists?

Anyone with steps on how to use the cable tester to check the lines I've run? I haven't used one before, but bought one.

I was not following this very closely because it seemed to be switch related.

If we go back to the start unless that tester you have displays more information it is garbage. You pretty much already know there is some kind of fault. If for example it tells you it is miswired that does not tell you what is wrong. The very cheap unit I linked will show you what wires connect to what pins on each end and if there are any that are not connected.

The thing that none of these cheap meters will do is tell you if you did something like split the pairs. Only the expensive fluke meters that can cost almost $1000 will do that.
What you need to do is look at the wire colors on each end and make sure it follows one of the 2 standard patterns and both ends are the same. The cheaper testing will just tell you that pin 1 connects to pin 1 and pin 2 connects to pin 2 but that does not mean it will actually function if you are using the wrong wires. If for example you use the orange and green wires rather than orange and orange/white. These 2 wires make up a pair and have to be on the proper pins. Look at 568a or 568b to see the correct patterns
