Wired LAN through house

12-08-2009, 20:52

Hi,

I've just run a cable from upstairs to downstairs - but it does not work - think I've wired it up wrong...

I've used one of these punch down outlets using the top colour code to wire it up.

And one of these RJ45's. With this, was a small square piece of plastic - I'm not sure what it's for - perhaps some kind of cable stay?

Any ideas?

Cheers
Lee

You're gonna need either:
1) a network cable tester
2) a continuity meter and a very long RJ45 extension lead
3) a continuity meter, a long piece of bell wire and an assistant

You've either got the wires jumbled up or one or more of the connections is not correct. Pin 1 should be connected to pin 1 etc.

Check you've used the right wiring here:

It doesn't matter if you use T565A or T565B (most common) - so long as you're consistent.

Hi,

Yeah I have a cable tester - in the car - not tried it yet.

Just wondered if it was cabled correctly on the punch down outlet...

The number of times I've wired it up and then tested to find one of the wires isn't connected properly, or somehow I've crossed it over. Be especially sure you are wiring both ends to the same pattern, there do seem to be two options. You just can't do cabling without a tester in your hand, not the car

Think I wired the punch down as a B and the RJ45 as an A according to the cable tester which is NOW IN MY HANDS!!

Appears to be working now - but a few drop outs. Will check again tomorrow.
