I am writing this review to help everyone out.

This splitter will take the input of one Ethernet RJ-45 connection and physically split it into two RJ-45 Ethernet connections. Please notice that you can only have one device turned-on at a time. This is a limitation of the Ethernet physical signaling. If you try to have two devices use the connection simultaneously, it will not work.

If you need two physical connections both on at the same time from one connection, please look for a switch like a 4-port, 5-port, or 8-port Dlink/Linksys/Netgear/HP/etc. More money, but this is the correct way to 'split' connections when you can't run more Ethernet cabling.

Hope this helps everyone!

Does what it's supposed to do which is split the signal. I bought it knowing I could only use the internet on one device at a time, but thought I could have both devices on at the same time. This is not true. I have it hooked up to my Mac and my Xbox 360. If either one is on, the other must be off for the internet to work. This is frustrating and inconvenient but much cheaper than a router so I'm fine with the situation. You should know that before you purchase.

[*** see Important Update to this review, at bottom!]

The reviewers who gave this splitter a bad rating are dead wrong. They do not understand what this device does. They failed to look at the schematic illustration above (alongside the other photos of it), which clearly shows how to use it.

Wrong reviews are annoying - if you are too lazy to read the instructions & educate yourself the tiniest bit about networking, then you have no business writing reviews to spread your stupidity and ignorance around the world. If you won't do your homework, then shut up - stop pretending that you did, and stop complaining that you failed the test: You *deserved* to fail it.

The purpose of these splitters is *NOT* to be able to buy a cheap splitter instead of having to buy either (a) a Modem-with-built-in-router/switch, or (b) a Modem PLUS a separate external router/switch, plus (c) two long cables to connect it to your two computers. That is what the ignorant people who wrote the bad reviews imagined that they could do with this splitter. Wrong, wrong, wrong!!

As the infamous (& fired) tech support person of legend once advised a customer: "Sir, the best solution to your problem is to (a) pack the computer back into its box, (b) take it back to the store, and (c) ask for a refund -- because you are TOO FRICKING STUPID to use a computer!"

For those who would prefer to educate themselves rather than abandoning their hopes of ever using computers, read on...

You need to purchase TWO of these. And employ them together, as shown in schematic. Then, yes, you can use two computers (or xboxes etc.) simultaneously.

Incorrectly named, I will attempt to upload picture of disassembled product. Each unit consists merely of eight wires cleverly bent so as to never cross another. Each of the eight(8) wires conducts to the same pin number for all 3 female sockets. This means a pair of these placed on ether end of an ethernet cable will not enable the cable to support two cat5e devices communicating the same time.

Poor quality. Of the two units purchased, one was mis-assembled, as one socket only had 7 conductors available for a RJ45 male jack.

You're all just complaining because you are too cheap to buy a router or switch to handle multiple internet connections simultaneously. This is a splitter, not a port switcher. It does exactly what it's supposed to do, it physically splits one line into two. That doesn't mean you can use both at the same time, there's no processing functionality in this item.

Compare it to a railroad. You have the railroad switch (this splitter) and the transfer station (a router or switch). You can have multiple trains going through the transfer station at the same time, however you can only have one train utilize a railroad switch at a time. Both are useful, however serve different purposes.

Go buy a $30 switch if you can't handle turning off one connection while using the other, and stop giving one star reviews to items that work properly. You're just too lazy to do some research on what you're buying.

There seems to be a big misunderstanding about how this item works. It's not going to split one source into two! You need a PAIR of these to do that! Ethernet has 8 wires, right? Well, 10/100mb connections only use four of them. Splitters like these allow you to use four wires on each side, but you have to use ANOTHER one of these on the other end, and feed it two connections from a switch and/or router. This is great if you only have one wire run to a location where you need two.

Understand what these are, the description is confusing.

This will **NOT** split an Ethernet connection for Ethernet computer networking of any kind. You will always need a ethernet switch to make one Ethernet connection into multiple. Again, if you are trying to take the output from your DSL/Cable modem and connect several devices, or if you are trying to take one cable from the wall and connect two computer devices to your network... THIS WILL NOT WORK for that. Search for an "Ethernet Switch" such as this: http://amzn.com/B001QUA6RA

This can be used if you are using an "ethernet cable" (Cat 5/6 cable), with the same RJ45 plugs for a purpose OTHER than computer ethernet networking. Such examples might be: Analog phone system, serial data transfer, or some other unusual application. It will physically split/share the wiring of an RJ45 socket, into two sockets. In my case, I'm running some LED lighting using CAT5 and wanted to be able to split off the wiring. It works fine for this kind of application.
