RJ45 blues...

[Jayhoo]

I'm trying to finish the network ports in my house, but for the life of me I can't seem to get them working.

Marked as 568A, the keystone wall jack is punched (left to right) as:
Green/White, Green, Blue/White, Blue, Orange/White, Orange, Brown/White, Brown

I matched that exact sequence on the cable in the basement, but all I get is a brief link light every 15-20 seconds or so, then it shuts off. Direct cable to router in basement works fine, tried a few cables, tried a few computers, same result...

Halp?

That's not 568A wiring. Should be green-white green, orange-white blue, blue-white orange, brown-white brown.
In any case, are you sure it is punched exactly that? I'd repunch the keystone walljack to at least be wired properly to either 568A or B standard. .

My friend, the mistake you are making is in the RJ 45s.
You're wiring the jacks correctly but the RJ 45s need to be as follows.

WHITE GREEN / GREEN
WHITE ORANGE / BLUE
WHITE BLUE / ORANGE
WHITE BROWN / BROWN

The orange pair is spit and the blue pair is inserted.
I have done thousands of them...................

as long as you're consistent with one of the three standards you're okay.

I usually use the A standard and don't split the pairs. At least in my house.

When I had to do it for work we used a different standard that I can't remember. Mostly because we used 25 pair, Cat5 cables.

To the OP - redo all your connections. I use scissors not side cutters when terminating cabling. Unless you're using punch down (not keystone jacks) the error rate is high.

Thanks for the suggestions guys. The wiring was done by the house builder. For whatever reason, the jack they elected to use is laid out as I described (there's even a sticker instructing them to use that colour sequence). I crimped the other end of the cable (in the basement) using the exact same colour sequence, and unfortunately I don't have anything to redo the keystone jacks... Sounds like i'm SOL and need to get in touch with the builder perhaps?

I figured even if the colour sequence was wrong, as long as both ends match it'd be ok, guess not.

I figured even if the colour sequence was wrong, as long as both ends match it'd be ok, guess not.The signal pairs are twisted throughout the cable to minimize EM interference and signal loss. It probably would have been OK to use different pairs if done consistently, but it's not the case here.

The keystone jacks are fine, if the colours there match the labels you should be good. What you're doing wrong is at the other end - VALUEMAN already mentioned it, but to fix this you'll need to wire the RJ45 as per this diagram: http://en.wikipedia.org/wiki/TIA/EIA-568#Wiring

This is how I make the RJ45 cables at work.

pin 1 is orange
pin 2 is orange/white
This is one pair

pin 3 is blue

pin 4 is green
pin 5 is green white
this is one pair

pin 6 is blue white

pin 7 is brown
pin 8 is brown brown
this is one pair

pins 3 and 6 is one pair but split up.

The other end is crimp the same way with the same colors in the same order to make a RJ45 cable.

I think there's alot of confusion in this thread. Maybe the OP can verify... but it sounds like the OP is going from a wall jack (keystone) to an RJ45 end. This is typically against networking standards as wiring usually goes from keystone (wall jack/patch panel) to keystone (wall jack/patch panel). The RJ45 cable is only used to connect a device (PC, Printer, Router, etc) to one of these keystones. That being said there is physically nothing stopping you from trying to do what you are doing, however from the sounds of it, it appears the person who did the Wall Jack installation didn't do to good of a job and if I had to guess I'd say the issue is the wires that are punched into the keystones aren't clean and some aren't making a connection. If you want to do your own networking you really need a crimping tool (which you have), a punch tool, and a tester... with a simple tester you would be able to figure out which wire is incorrect or not making a proper connection.
