I am writing this review to inform, not really rating this product.
Rickrad
I wanted to run a single line from the router and split it to the receiver for internet radio, and also to the blu ray, but it doesn't work.

When I try to use the adapter to connect my wireless router to use my laptop and access my phone, I cannot.

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.

k1114 is correct that 100mb ethernet only requires 4 conductors. Unfortunately, these splitters are not wired to use 4 wires for each connector - all 8 go to both (I took mine apart to see), so you can't simultaneously use two devices, even with two splitters. It's a shame - the only splitters I've found wired for two devices are from Cables To Go and are much pricier ($13 each), and have a male on the single end instead of a female. Someone should start selling cheap splitters wired the right way!

This is design to be a multiple coupler, one live connection at a time. one side does not work, got 2, neither of them work. Normal junk from China. Got what I paid for, very little. Does not work as advertised.

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.

this was a great device and does just what it suppose to. most people I have read gave it a low review because they dont know what it does. they think it splits the line in two so that they can run two devices from one modem at the same time like haveing two modems. but you cant you cand hook up two devices like I did my xbox and ps3 are both connected with the splitter so when I play one of them I will be online but I cant play the xbox and ps3 at the same time and b online at the same time. but then again I dont play both at the same time. I got tired of moving my cable from one unit to the other so I both this splitter so I dont have to. but I will say that I did try to hook up a lap top to it but it wouldnt work. not computer savy enough to explain why it would nor did I look into it to find the problem since it works great with my game systems thats why I bought it so no problems for me on that end.

I bought 2 of these items thinking they were similar to the item Cables to Go 37133 2-Port RJ45 Splitter/Combiner since there was a picture on the item page for this product just like a picture describing what the Cables to Go 37133 2-Port RJ45 Splitter/Combiner does. You see, the Cables to Go 2-Port RJ45 Splitter/Combiner has a male connector on one end that I did not need. So I thought this product was the same only without the male connector.
When I plugged everything in, nothing worked, so I opened it up. Its designed as if its for regular phone lines but with ethernet female connections. But thats not how ethernet signals work, they're not like phone lines that can be connected together or bridged.
You'll need a ethernet switch if you have more than 2 ethernet devices or the Cables to Go 37133 2-Port RJ45 Splitter/Combiner. The Cables to Go 37133 2-Port RJ45 Splitter/Combiner utilizes the 4 wires not used in ethernet wire. You see, ethernet wire actually only uses 4 out of the 8 wires in them to gave us internet so the Cables to Go 37133 2-Port RJ45 Splitter/Combiner uses the other 4 wires so you can connect another ethernet device.
THIS PRODUCT DOESN'T WORK LIKE THAT AT ALL. To me, its practically useless if I still have to disconnect one device so I can use another.
If you're interested in the Cables to Go 37133 2-Port RJ45 Splitter/Combiner, you'll need to buy 2, one at where your devices are and the other at the router.
hope this helps...
