    I'm quite tired, foreign and don't really know of what I'm trying to achieve is possible or quite two to do it... Figured I'd just record quick little video with problem and one of you geniuses can figure out if this is possible. I did read .. or skim somewhere (Ih ave upc 120meg and technicolor 7200 router). is that it should be possible to use two ethernet cables on one port and they'll just be able to do 100meg but I dont mind the extra 20.

    sorry for the jumbled post but AAAAAAAAAAAAAHHH. I thought It'd be easy cause I could crimp.



    sec tying to get the bloo.. url right

    i can take some photos of these... the ethernet cables confused me at first..cause they're not alll candy cane coloured. thought it was a scam but.. if you figure out the solution for this terrible explanation of my little problem then you are a super genius. godspeed.

    Madness. What you're trying to do is ridiculous, You do not split Ethernet, you use a switch. Get a simple 5 or 8 port Ethernet switch should cost around a tenner online.

    1 cable, 1 device on either end. If that device happens to be a switch, other devices can connect to that and communicate through it.

    If you really want to it's easy enough when you know a few things :

    - the wires are in pairs twisted together <blue & blue/white> <green & green/white >

    - to get 100MB you only need 2 pairs

    - only pins 1,2,3 and 6 are needed for 100MB


    - 1 & 2 are a "pair" , 3 & 6 are a "pair"


    If your sockets are colour coded do it this way :
    socket 1 :

    green & green/white markings
    green & green/white pair of wires

    orange & orange/white markings
    orange & orange/white pair of wires
    socket 2

    green & green/white markings
    blue & blue/white pairof wires

    green & green/white markings
    brown & brown/white pair of wires


    like this - your socket may be different

    not the thing to be doing though

    This will not work with both at the same time, auto-negotiation between the end device and the router selects 10/100 Ethernet and disables two pairs

    Of course not - you do the same at the other end

    Not recommended at all though for many reasons

    - yer going backwards - run another cable n get over it

    - get a small gigabit switch instead of messing

    - just don't do it

    etc etc

    This can never work with devices. All this allows one is "split" a network cable and allow two devices to share a cable run. Or if one wanted two network ports on the wall but there was only one cable in the wall.

    We used to use them to allow two devices to share a single port on the patch panel. But switches are sooo cheap now it hardly worth it anymore.

    Splitters come in a matched pair, one for splitting and one for merging.

    Here's an example:
