I am going to have a crack at wiring some of my home network in the morning. I have done a google search on 568A wiring and come up with this:

There appear to be two methods, crossover and straight. How do I decide which way to wire?

I have got a patch panel which will connect to my modem/router using .3m patch cables purchased from cablesdirect.

What is the standard wiring in ethernet sockets on computers/routers etc, crossover or straight?

The patch panel will have 5-6 cat5e cables coming in to it from around the house. I have not wired any plugs on the other end of the cat5e cable yet either but have some sockets and faceplates ready to go.

Nowadays with new routers/switches a good guide is
Crossover - PC to PC
Straight/Patch - PC to router

However most routers will allow you to use either crossover or straight, but i'd stick with straight.

Just wire both the patch panel and the wall plate keystones as 568A. You should not crossover. Patch cords should be straight.

There is no reason why you could not wire the panel and wallplates 568B as long as each end is the same (ie no crossover) howeveer the NZ/AUS standard is for 568A but this is not mandatory. In the end it makes no diff as long as each pair is straight through.

If you are going to do your own in-house wiring, I recommend that you buy a cable tester.

I tried to do wiring without one. It was 4 hours of hell. Then I got smart, bought a tester and solved my problem instantly.
It has saved me insane amounts of time ever since.

DSE sells them for NZ$50.

Just wired up my patch panel and two RJ-45 outlets and it all works! Thanks for everyones help, it was actually much easier than I thought, the colour coding makes it pretty simple.

I've wired up so many CAT 6 cables around our place that's it's second nature. It doesn't matter whether you go a or b, always go straight through.
Try and use connectors that are cat 6 compliant and practise making the distance of the exposed untwisted pairs as short as possible as this educes near end contenuation and cross-talk. Good practise even if it's a 100Mbps network.
Good thing about using the cat 6 connectors is it staggers the individual cables so you should see a row or white on top and coloured on the bottom...very handy when getting the ordering of the colours right.
