Ethernet RJ45 cable is used in many homes and businesses to carry data.
Wireless is also a good option but is prone to errors, and the speeds are often much slower compared to Ethernet.
Running Ethernet is also much more secure as data can not be picked up as it can with wireless.
After Ethernet is installed throughout a home or business, tracking which cable goes to which room or finding a bad connection can be difficult.
This task is made easy with a good network Ethernet RJ45 cable tester.
What is a Network RJ45 Ethernet Tester?
A network RJ45 Ethernet tester can help to troubleshoot problems in a line as well as track down a wire.
Network testers will have different features, such as a toner that makes a noise on a single Ethernet line.
A unit with a tone generators can connect to one side of a line and beep when close to the other side, tracking down a connection.
Using a network RJ45 tester makes working with Ethernet much easier.
There are many available, with some of our favorite picks below.
As always, be sure to read the review on Amazon, forums, or elsewhere to be sure a unit is the right pick for you.

How Do I Test an Ethernet RJ45 Network Cable?
An Ethernet network scan tool is needed to run a test on the cable.
A network scan tool will have features to help troubleshoot an Ethernet RJ45 connection.
The tool will have several tests that can be run, such as toning a wire to find the other side or continuity to check for a break or short.
Can a Tester Find a Shorted or Open Wire?
Yes, most network testers can test a cable for an open or shorted connection.
One side of the kit will have an emitter that sends a signal down a cable while the other side is plugged into a receiver.
The two work together to test each wire for an open or short and display the results.
If you need a LAN tester to find the other side of an Ethernet wire or other test, there are many good network scan tools.
A good generator and probe kit can help track down a long cable run behind walls or attics to other rooms.
This includes Ethernet cable testers for Cat5, Cat5e, Cat6e, Cat7, and more.
A tone generator and probe can also test if one of the wires is shorted or open, helping to troubleshoot any problems.

With extensive experience working as an electrician, I can confidently say that Elegiant’s network cable tester is among the best tools to test cord connections. I came across this product while working on a LAN connection set-up for a local company.
However, I do have to note that this tester doesn’t come with circuit protections. Just make sure that the cable connections you’ll test aren’t carrying strong electric currents that could tinker with the test result, and you’ll be fine.
