network cable tester

I have never had to search down paths for cables in the past in our networking room.  I see that on the wall plate it shows numbers like 1-10 and 1-11.  I have checked many rooms and when I go to the networking patch panel for 1-10 and unplug it the computer on the corresponding end still has internet connection.  So 1-10 on the wall plate does not correspond to 1-10 on the patch panel.  This is happening on many numbers.  Did the people who installed this be wrong many times?  Very surprising.  Anyway.  How would I go about finding the cable in each of the rooms and where it is actually going into the patch panel?  What do I use for a tester and how would I hook it up?

You just need a cable or tone generator, or sometimes just called cable toner.

You plug the tone generator into the wall plate turn the thing on, and take the wand into the other room, hold the button in and you will hear a loud ringing noise when you come across the right wire.

Will the toner make a noise if I stick it in the network jack of the patch panel if there is not a cable inserted?

So if you stick the toner into the patch panel and turn it on, if you have a wire going back to the wall plate, you will also hear it in that direction. It does not care where you plug it in, thats why it has a few connectors for patch cables, telco cables, and clampons for whatever. Hook it to one end, use the wand at the other end to hear the tone.
