I’m thinking the people rating this poorly don’t understand how to use it. It WON’T split a single Ethernet CONNECTION into two. It WILL enable a single Ethernet CABLE (which has 8 wires) to carry two connections (which require 4 wires each). This is helpful in places where you have a single cable running from your router (typically in a wiring closet) to two devices, and can’t easily run a second cable — i.e., where one cable is already installed in the walls.
Here’s how you use it: Run Ethernet cables from 2 ports of your router into the female jacks of the first splitter. Plug the male end of that splitter into the jack in your wiring closet that runs to the part of your house you want. Plug the male end of the second splitter into the Ethernet jack at the other end of that cable run (i.e., in the room where the devices are located). Run Ethernet cables from the female jacks of the second splitter to the devices.
If you want to use a single Ethernet connection for two devices, these splitters won’t work; you need a router that shares the connection among the devices.

I dont own this item, but I’m thinking of buying some, then I saw the bad reviews..
From reading the reviews, it seems, at least from the first one, that the person didn’t know how to use the item.. This is NOT a 3 port switch. You can NOT plug the male plug into a switch and have it run two PCs… It is splitting the 4 pairs (8 wires) into TWO separate two-pair outlets.
Ethernet only uses pins 1, 2, 3, and 6, leaving 4, 5, 7, and 8 unused. This device connects pins 1, 2, 3, and 6 on the male to 1, 2, 3, and 6 on one of the femals jacks, and pins 4, 5,7, and 8 of the male go to pins 1, 2, 3, and 6 of the OTHER female, giving you two separate paths of pins 1, 2, 3 and 6.
The idea is that if you need two PCs where you only have one jack in the wall, you plug one of these into the jack, and another one into the patch panel, and it allows you to hook two PCs to two separate switch ports. You will STILL need 2 separate switch ports to connect your two PCs, and you will ALWAYS need these splitters in pairs because you’ll need to have one on each end of your 4-pair house cable.
Now.. Does this make sense? And, given this description, are any of the negative reviews still valid? I dont want to buy a piece of junk, but as this is not even an active device, but rather just like a wiring adapter, I can’t imagine that it could fail, short of it being a physically poorly constructed device…

I purchased this item to provide an additional port for my single port modem, so I wouldn’t have to keep switching the ethernet cables between my computer and the modem, or between my on-line Netflix TV viewing box and the modem.
This item does not do that. I “chatted” with the mfr (Cables To Go)and they said it would not do that. Too late for me (not worth returning) but not for you.
If you wish to split your single port ethernet modem into two outputs get this instead:
TRENDnet 5-Port 10/100Mbps Ethernet Switch TE100-S5 (Blue)
$11.98
you will also need a short ethernet cable w/two male ends to go between your modem and the 5-port switch. Get this:
RiteAV – Cat5e Network Ethernet Cable – Blue – 3 ft.
$1.50
Good luck.

First off, I didn’t buy these from this vendor but have used this product and brand in the past. I just wanted to help if there are any questions about how these work. You have to use these in pairs. The scenario where you would use these is if you have one network port in your office and want two. You would plug a splitter in the wall jack and and then the other splitter into the patch panel port. If you are just using a cable instead of wall plates and patch panels you will also need to Cat5 couplers. Then run two patch cables from the splitter in the office to two computers. At the other end run two patch cables from the splitter into your switch.

Disregard any reviews that claim this device doesn’t work, or works “only half”. The description of this item could be more detailed and clear, specifically that you have to buy them IN PAIRS (which I think should be the default packaging qty). As a previous reviewer said, this is NOT a switch. 100BT ethernet connections (not power-over-ethernet) only require 4 pins to operate, and a standard fully-wired CAT5UTP cable has 8 wires (4 pair). All this does is use the “unused” pairs and move them to the unused section of the wire. The other end / second of these breaks it back out.
You HAVE to have all 8 wires testing good, and connected to your port or patch panels. Not all installers do this, or test the unused wires or pins.
I cannot speak for the seller of this device yet, however.
