Turning a 568C cable into an ethernet port

I'm in a UK house that has a Master Socket 5c downstairs and data points in 2 rooms upstairs. I'm wanting to get wired internet to my PC in my office upstairs. The data point socket in my office has a 568C cable that goes to a keystone jack, which has 6 'inputs' (see photo) - I believe this is for a LAN phone to be plugged in. I've not been able to find this keystone jack online... At the start of this operation only 3 of the 6 wires are wired up, the other 5 are loose. Could it be wired up so as to magically turn it into something that would support internet?

So far I've tried attaching a cat6 keystone jack to the 568C cable but it didn't work, either in 568B or 568A wiring formats. From basic research I think the 568B wiring should have worked but nope. Could this in theory work?

(This may be a dumb question! I can build PCs and am fairly techy but with this kind of thing I haven't a clue)

You’ve nothing to lose (and everything to gain) by trying it. A couple of keystones will be maybe £10 and don’t skimp on the punch down tool (£25 will get you a proper pro one) and bob‘s your uncle.

 
Well, I certainly skimped on the punch down tool... used a thin metal ruler to push them in, it seems to work but is this just awful and I MUST buy a punch down tool? I will if necessary (thanks for the link)

Here's the cat6 keystone jack I put on.

This didn't work, quite frustrating!

Is the master socket wired to 568B standard? If not then you just have a mish mash of cabling at each end.

If it's not working it's probably due to the insane amount of crosstalk that five miles of untwisted cores are picking up

Is that referencing my appalling job with how the 8 wires approach the keystone (i.e they're twisted) or the rest of it (going into the walls etc)?

It's the length of wires leading to the keystone. Ideally you don't want to unwind more cable than you need before it gets terminated into the keystone. I'd have thought it'd still work though just don't expect to support higher speeds (I'm sure it'd do 1GBps).
 
Just make a little gap in each pair with your fingernail

Force the pairs down over the little humps on the keystone.

Then punch down - bear in mind that the scissor type Krone tools don't work on these. You need a 110 punch-down tool - or a total keystone punchdown tool.

You should have the outer sheath as close as possible to the keystone.

You definitely terminated the two ends of the same cable in jack's? Telephone wiring is usually just daisy chained from one socket to the next.

No, a bit embarrassing for me... I had real trouble getting the master socket cover off and so just hoped they were connected, they were not. Anyway, I put a rj45 keystone jack on the cat5e cable running up to my office and both ends are now talking but...

... this didn't work - using a cable tester unit, only lights 4&5 are lighting up (on both ends), no others in the 1-8 sequence. Before attaching the keystone jack I had put on a rj45 plug and ran the test, same - only 4&5 lit up. Why could this be?

Do your best to look away from my unholy wiring, it makes me ill and will be redone when the testing phase is over. Thanks for the assistance and patience!

4 and 5 will be the Blue/White and Blue conductors so it's likely that the fact that those conductors are attached to the Master Socket are the only ones actually connected. Are you sure you are testing the right connections?
 
So 4 (blue) and 5 (white blue) are going into the master socket, seen in the photo. That sort of explains the light sequence. What would I need... is there a new master socket that could be bought where all 8 wires could be connected? My level of ignorance is sky high.
 
The wiring goes via another point. Also you're wasting lots of time if you're trying to punch things down with a ruler rather than the proper tool.
 
I don't really see any option but to pull all the points and map out how they are connected. It's unclear from what has been posted if you have a single cable running between points (which would work) or if, as I suspect (and @Dg834man posted earlier), that you have a loop in which case you have one leg with everything connected at both ends and the rest is only connected at conductors 4 and 5. And if that is the case then those conductors could be live and carrying way more than the 5V you'd want to feed into a computer network card.

In a normal network all the data cables would come back to one central point (a patch panel or bundle of cable ends) and you would then use a switch or hub to route traffic between them. The best you will get with the system you are working on is a single connection between 2 rooms and that may well be adequate for what you want.
 
It now works :D @Dg834man was correct, the cable was daisy chained through the house. The other jacks were either not wired up at all or had 2 wires barely pushed in - quite shoddy work I guess, not even a LAN phone could have been plugged in.

I bought several RJ45 jacks and wired each socket up and finally it worked, just need to sort out my unholy wiring. Thanks for all the help and figuring out all the info I wasn't even aware of!
