Your cart is empty.A Networx CAT6 Gigabit RJ45 Loopback Tester is an exceedingly user friendly cable tester. Even the architecture is pretty simple. It looks like a simple plug at first glance but the compact, rugged design makes it highly portable and usable in the tightest corners. All you have to do is simply plug the Networx CAT6 Gigabit RJ45 loopback tester into the jack that you want to test or the one you are suspicious about. If the link LED on your switch is active, then that means that the connection is operating perfectly. These Loop back testers will make the life of a network administrator really easy. The Networx RJ45 Loop back tester will negate the necessity to carry a bulky network hub around.

worked flawlessly. I was instructed to build a cord, but didn't want to take a chance. This was cheap insurance it was done right. Keep one in your arsenal.

Many older devices without auto-negotiation of RX-TX pin positions need a crossover cable rather than a common straight-through cable. This makes it easy to swap without needing a separate crossover cable.

It's basic, but it's necessary, and it works VERY well. Can't tell what switchport a wall port goes to? Throw on loopback detection on every port, plug this thing in, BOOM! Port identified! WAY easier than toning out cables!

I bought it and tested it by plugging into my 24 port gigabit switch. The port light should have lit, but did not. So I returned it in exchange for another, and the same thing happened with the replacement. Checking the reviews, I saw some people say it doesn't work with gigabit equipment, so I tried it on a 10/100 switch, and sure enough, it worked fine, but it is clearly labelled as "Networx CAT6 Gigabit RJ45 Loopback Tester" ... gigabit.

Despite the warnings from other buyers and the fact that it is made inChina, I bought the device. Unsurprisingly it did not work. A refund is on the way. Hopefully that will work as it is made in the USA!

I got no use out of this. I won't give it a bad review just for that, but it could be more clear as to what it does. I wanted to use it to test my home data jacks, but I guess it's really only made to test cables? I still don't get it.
