Network jacks are stationary ports that allow you to connect to your LAN (local area network) or WAN (wide area network). And though network jacks are hard-wired, they can also be the cause of connection problems for your networking components it there is a problem with the network cable connected to the jack. But with the help of a network jack tester, problem network cables can be weeded out of the bundle of properly functioning cables.

Purchase a compatible SuperLooper for the type of network you are on, such as "T1/E1," "ISDN" or a standard Ethernet network (see Resources).
Disconnect any cable currently occupying the network jack that you wish to test, and then check out your network's router or switchboard. Note which ports' LEDs are lit and which ones are not.
Plug the male end of the Superlooper into the network jack that you want to test. Return to the router or switchboard.
Check the router or switch for a port with a newly lit LED. If there is a newly lit LED light, then there are no problems with the network jack--and you also have confirmation as to which port the network jack is connected to. If there are no new LEDs lit, then you need to check the wiring--connected to the network jack in question--for a short or disconnection.
