Could somebody recomend a 1 in 2 out splitter. I have tried a couple of the cheep plastic ones and no good. so i dont want to waste anymore money.

[Marks DTM Calib]

You can't simply split ethernet

[Andy H]

This will do what you asked - problem is that your description sounds more like an adsl filter.

Sorry not enough details..Due to my wifi and my laptop being crap i have ran a ethernet cable from my main computer into my man cave.I wanted it to run my laptop and my ps3. This will only be one at a time. but rather than having to keep unplugging it and swapping it over i thought i would get a splitter. They is loads on gaybay .

[Andy H]

OK

My previous advice still stands. £20 for a Netgear FS105 (pictured).

As Marks DTM Calib pointed out the Ethernet standard doesn't support passive splitters so either keep plugging one in at a time or use a network hub.

 Below is a link to the same model as Andy H has only now it does Gigabit as well .  Less than £20 delivered

Yep splitters just no good - you need an ethenet switch as others have suggested

To be clear, this and other suitable devices will be powered - you cant do it any other way .........

Cat5 cable has 8 wires which give 2 network connections. Only one is normally used, so yes you can use ethernet splitters to go from 2 to 1 and back to 1 to 2, but using all of the single cable wires.

What you need is a pair of these.

Yes, in fact, you don't even need those if you just wire two sockets on the faceplate at either end of the link, using two pairs for each, and remembering the colour scheme you use, of course.

That will work if all 4 pairs are correctly wired all the way through, will require 2 ports on a device somewhere though - so may well serve the purpose properly.

[Kevin Wood]

It's also worth mentioning that if the devices at either end support gigabit ethernet they will require all 4 pairs to be connected and may even fail to negotiate down to 100mbit in that scenario.

[Marks DTM Calib]

Good look on the 'unused pins' bit for 100baseT, there is a LOT of things that happen to those pins including them being grounded in the terminating equipment.

And when you then think POE it gets worse!

[Marks DTM Calib]

I should add that if using the cheapo splitter types, you need one at each end of the cable (they are a way of getting two 100 base T ports over a single cable), this will would requrie two ports in your swicth/router at the head end

As Mark says need one at each end, uses the the normally 2 Voice pairs for the second Data run, or you can make up your own with some spare Data Outlets. only good for up to 100 Mps T Base though.
