Cable Matters Ethernet Cable Share Kit in Black up to 100 Mbps - Check The Connection Diagram Before Purchasing - This is NOT a Two-Pack - Must Be Used in a Pair

It works just fine. I think people just have a misconception about what this does and how it works because it is not really explained in the product description. This exists to serve a very simple purpose: to let you connect two network devices to a single existing network cable when, for whatever reason, you don't want to run another network cable or install a full-blown Ethernet switch. I am using this kit to connect two IP security cameras outdoors without having to run a second cable.*** How it works ***Normal network cables contain 8 wires. A 1000 Mbps (gigabit) network link requires all 8 wires. However a 100 Mbps link only requires 4 wires, leaving the other 4 unused. This kit splits those four extra wires off to "Jack 2" so that you can connect a second device. Any device normally capable of gigabit speed should work too, but it will only be able to achieve 100 Mbps speed.*** How to use it ***Unfortunately, this kit does not come with all you need. In addition to this "kit" you also need two RJ45 couplers and four additional network cables likely you will want really short cables for this). I am assuming that you have already run one long network cable between your router/switch and a device at a remote location.Here is how you would typically use the kit:Step 1) Connect an RJ45 coupler to each end of your existing long network cable.Step 2) The cable sharing kit comes with two identical dongles. Connect one dongle to each RJ45 coupler. Now, Jacks 1 and 2 on the first dongle are connected to Jacks 1 and 2 on the second dongle.Step 3) Connect both Jack 1 and Jack 2 to the router/switch using short network cables.Step 4) At the other end, connect your two devices to the two open RJ45 ports.See the attached diagram for how you might set this up to feed two IP security cameras.

Worked as promised. I noticed some people complaining that only one side worked. Be aware that this “splitter” works by using the other half of the wires in an Ethernet cable that generally go unused. I thought I had the same problem until I looked closely at one of my cables’ connectors. It was only half populated. Many cheap cables that come “free” with various devices are like this. Once I used proper cables it worked great.

I an ethernet connection for cable internet. I ordered the Amazon Fire TV stick. After receiving the stick I realized I needed an adapter for the ethernet connection. After receiving the ethernet adapter I realized I needed an ethernet splitter so I could operate the computer and TV simultaneously and ordered this product. I plugged it in to the modem and connected to my device and no internet connection. As I look at the miniature instruction booklet I realize I need to be a cable guy technician to know what to do to make this work and I don't even really know if it is what I really need. I often wonder when these technologies are invented to improve the digital experience are they been made for technicians or the average person?

I can only say that it seems like it would work well. What I need is something different so I can't actually use this. My husband said he liked the way it was made, and looked like a very good product.

I'm not sure about some of the negative reviews on here. I think some customers just don't understand how these adapters are supposed to work. In any case, they work perfectly for me.My setup is as follows:I've got the cable TV Ethernet jack connected to jack 1 on one of the modules.From my router (my home network) I've got one of its Ethernet jacks connected to jack 2 on that same module (NOTE: My cable box needs to be on a completely separate LAN, which is just a limitation of the ISP's equipment).The plug on that module is connected to an 8-wire jack in my network panel (NOTE: all other jacks in my network panel are 4-wire, and this would not work with those).The second module's plug is connected to the wall plate jack in my living room (the other end of the 8-wire connection from the network panel).Jack 1 of the second module is connected to my cable TV box's Ethernet jack.Jack 2 of the second module is connected to my Apple TV's Ethernet.Now, for jacks 1 and 2, you can connect your equipment using 4-wire Ethernet cables or 8-wire Ethernet cables. It will work with either.However, if you decide to extend the module's plug with an Ethernet cable, it MUST be 8-wire. You will lose jack 2 if you use a 4-wire cable and coupler to extend the module's plug.By the way, although my router's ports are capable of gigabit speeds, you need 8-wires for that. Fortunately, I just don't need those speeds and 100MBps is more than adequate for me.

Working well for two IP security cameras over one ethernet cable. Main reason not given five stars was lack of a protective boot on the network plug to protect it from being broken off. Many people won't care about that and that is common.

If you read the description, it clearly states that you will need two ethernet lines in, to make this work and you will need two splitters. You put one splitter on the box side, with one ethernet line in to the splitter from the box and one ethernet line into the other side of the splitter, run to your final destination. Then plug the second splitter into the final destination. You can then plug in two devices. Basically, you will go from two lines at the box side, down to one line, back to two lines at the end destination. As an example, if your final destination is 25 feet from the box, you can run one ethernet line and use the splitter, so you do not have to run two lines, 25 feet. So far, the splitters that I have bought, work perfectly. I will admit, I made the same mistake of many of the reveiws and tried to plug in one splitter and only one side worked. If you read the description and directions, you can make this work.

Did not work. I wanted it to split the ethernet connection to 2 computers but instead it only worked for one side. The picture split up the CAT5 pins making it unable to function properly. Advice: Spend more money and buy a 5 port box.

Todo llego en orden

El paquete me llegó bien, yo lo utilizo para conectar dos computadoras a internet (para ello necesité 4 cables ethernet pequeños, 1 largo, este producto y 2 adaptadores de ethernet a ethernet)

Queria dividir la señal de ethernet y no funcionó, quizá no sea lo que necesitaba

Cambié el cable, tienen un cable cortito y para mi aplicación necesité abrirlo y sustituir el cable por el que ya tenía en el ducto

Hasta él momento está trabajando sin problemas
