How-To: Run your own network wiring


[/URL][Only registered and activated users can see links] ([Only registered and activated users can see links])



Wherever you call home, it probably didn't come wired up for that most precious of home utilities: internet access. Sometimes wireless networking can only take you so far. Guerrilla network wiring might sound a little strong, but sometimes it ends up feeling like an episode of MacGyver, without the bombs. (Unless you count flaming laptops.) In today's How-To, we'll show you how to make your own cables and teach you a few tricks for getting them where you need 'em most around the house.

The supplies for making network cable are simple. We'll need:


RJ-45 connectors
RJ-45 crimping tool
Category 5 cable
Wire strippers

These used to be pretty esoteric, but these days you can get crimpers and connectors at most computer stores. (The cable is usually cheaper at the hardware store.)


[Only registered and activated users can see links] ([Only registered and activated users can see links])




To crimp your own RJ-45, you'll first need understand the pinouts. A regular ethernet cable consists of four pairs of twisted wires. Each pair needs to be connected in the proper order for the network connection to work. For a normal cable, both ends are connected in the same order. Pinouts.ru ([Only registered and activated users can see links]) is handy, but we've found that color graphics are easier ([Only registered and activated users can see links]) to keep track of.

There are a couple of standards for ethernet wiring. They're generally the same, but they like to use different colors. Just make sure you use the same standard for each end of a cable and everything will be fine.

Cut the sheath off of the cable about an inch or so from the end. of the wires. Be careful not to nick the wires in the process.

You don't need to strip any of the wires. Just spread the wires apart, un-twist them down to the sheath and put them in the order they'll go in the the connector.

Straighten each of the wires and pull them together so they're flat and in the right order.


[Only registered and activated users can see links] ([Only registered and activated users can see links])




Cut the wires across the tips so that they are flat across the end. Use a smaller wire cutter so that each wire will stay in the right shape. (If they get distorted, they might not fit into the connector very well)


[Only registered and activated users can see links] ([Only registered and activated users can see links])




Slide them into the plug until the ends of the wires are touching the far end of the connector. You might want to compare the end to a pre-made cable to double check everything before crimping.


[Only registered and activated users can see links] ([Only registered and activated users can see links])




Insert the connector and wire into your crimping tool. Crimp the connector and use plenty of force to get solid connections. Repeat the process for the opposite end, and you've made your own network cable. (If you can get/borrow them, we recommend ratcheting crimpers over the cheapies.)

Now that you can make your own cables, it's far easier to run Cat 5 anywhere you want it.

One of our favorite tricks is to run cables through the A/C vents. Unfinished basements are fantastic for running wires. Here we've slipped it in between the actual duct and the hole it runs through.


[Only registered and activated users can see links] ([Only registered and activated users can see links])




Up top, we ran the wire through one of the slits in the air vent. When we move out, we'll just cut the end off the wire and remove it.

To get our TiVo networked, we took advantage of the pre-existing monster hole in the floor.

For easy removal and wiring containment, a few zip ties go a long way.

That's all there is to it. Don't be afraid to get out your drill, but there's usually an easier to run your network wiring. It's often noted that one should use plenum rated cable for runs through air conditioning ducts. We've found that basic Cat 5 is pretty tough stuff. (We had a piece strung between two houses for over a year and never had a problem with the network connection.) You can probably get away with non rated Cat-5 for short term use, but you probably know as well as we that one gets what one pays for -- so use the good stuff, and go nuts!

I'm going to run cable to the new room addition eventually and now I can see how to make the cable ends and have them work right. Thanks for the post ;)

Cat6 is just like this... Just the cable is only different.... Both still have 8 cables inside.

Great post CSB!
Hiding cables is a task in itself. I want one room to act as the network room, and then have Cat 5 cable running to every room in the house. A lot of work on hiding wires behind walls, but for network sharing it is the fastest option. Wireless networking is great and I currently use it, but I notice a dramatic difference in upload and download speeds on wireless networks.

Nice post. I have tried to teach everyone who works with me how to do this fast and efficiently but it can be challenging. I think the easiest way I have found to help people understand is to instill in them that a standard network crimp only requires that wire# 1 & 2 and #3 & 6 re the only wires required to have a network connection made and that the others are for POE or spares.

Good post was thinking of doing something similar but never had the time. I just finished a job that we ran 16000 ft of Cat 5 including some plenum.

One thing I have noticed is that there seems to be a misconception in the industry about what is standard for the order of the 4 pairs and what they actually do.

When inserting the pairs holding the RJ45 connector with the clip facing down the correct order should be as follows (at least in the states):
1) white orange
2) orange
3) white green
4) Blue
5) white Blue
6) green
7) white brown
8) brown

The interesting thing is that the only pairs you actually need for an internet or network connection is pairs 1,2,3 & 6. (In other words you can actually make two connections out of one cable if you really wanted to)

Pair 4 and 5 are commonly used for POE or power over ethernet and the other spare pair 7 and 8 are also utilized for this in some cases.

Just wanted to share my knowledge since I run this cable on a daily basis for my company as well as utilize it for Surveillance Cameras to power them and send video.
