Hi, I was wondering maybe someone with some experience can give me some tippers. I have been trying to make my own ethernet cable out of Cat5e with the straight through configuration. However, the resulting cable doesn't seem to be working for me.
Here is the wire configuration I used on both ends.
white-orange
solid orange
white-green
solid blue
white-blue
solid green
white-brown
solid brown
I know the problem is definitely with the cable and not anything else, such as my router and other configurations. I'm trying to make my own cables to set up a home network with a router.

Do you get a light on the ethernet card and/or router when you plug them in?
Are you sure you're getting the wires all the way into the connector?
Are you sure that you don't have one connector flipped around in comparison to the other end?

I get no reaction when I plug in the wires. No light on the ethernet card or router. No reaction from the computer.
Am I sure I'm getting all the wires flush with the connector? Well, all I can say is I have had no previous experience doing this so it is my first time. They do look like they've reached all the way to the end and I put 100% effort trying to make no mistakes. I've even cut the ends and done it again a couple of times over.
I've read that the limit for the cable length is 328ft, but mine is under 100ft. I've checked and double checked the order of my wires.

First off you color scheme is correct. Hold the wires with that color scheme (looking left to right) firmly between left thumb and forefinger. Using side cutters, cut the wires at once so that they are even. Holding the connector with your right hand and with the clip down, slide the connector over the wires. Push firmly and look at the end. You should be able to clearly see all 8 copper ends. If not, back the connector off and re-cut just enough to make the wires even again. Slide connector back on.
When you have it so that all 8 copper ends are clearly visable thru end of connector slide the connector into the crimper. You are using your left hand to do this as you are still firmly holding the wires. When the connector is all the way in the crimper, crimp down enough so that the crimper is holding the end before releasing with your left hand. Finish the crimp.
I always crimp, release and crimp the connector a second time.

Thanks guys for all the advice. Just wanna let u guys know that I got the cable to work. The trouble lied in the color scheme, believe it or not. I don't understand that either. This is the scheme that one of my colleagues gave me:
Orange white
Orange
Green white
Brown
Brown white
Green
Blue white
Blue
I've never had any experience doing this before, so I don't have any in depth technical knowledge about this stuff. But all the websites that I have found including Linksys, posted the color scheme which I have quoted in my first post. I haven't been able to find the above scheme anywhere though. According to what I've read in Linksys, only wires 1,2,3, and 6 (which are orange-white, orange, green-white, green) are responsible for handling data. This is why I don't understand why the ordering of the other wires mattered. Moreover, since the first scheme was posted on many sites, that combo should obviously work. However, I tried numerous times but it doesn't. This color scheme worked for me on my first try. That was quite puzzling to me. Anway, I thought I should just post my discovery in case anyone else may be having a similar problem as mine. If you are almost sure that the problem is not due to your handiwork, then don't hesitate to try the above scheme. I would definetely appreciate it if anyone is able to post any reasons to why my situation happened that way.
This scheme worked as a straight through cable, I do not know if a cross-over of this scheme will work.

You are correct in that ethernet only needs 1,2,3 and 6. Telco standards are what you posted first. The later only reveresed the Blue and Brown pair which are not used anyway with ethernet. The fact that you reversed them has no bearing on why it worked. The fact that you got a good crimp is the reason it works.
