why isn't my Ethernet not working when plugged in to router (2 wire) I have a 100' cable?

Question

made my own cable and tried with facotry cable and it woks well,checked the wiring about three times now with meter and also plug ends I always get the unplugged LAN message

Answer 1

How did you wire up your cable? If you paired up the colors straight through it won't work.

Hold the plug in your hand with the contacts facing up and the cable opening pointing to the right. From bottom to top, the color sequencing is:

White-Orange (White with orange stripe)
Orange (Orange with white stripe)
White-Green
Blue
White-Blue
Green
White-Brown
Brown

It's the same on both ends of the cable. If you wire it up any other way it won't work.

When you strip the outer jacket make sure you don't nick the wires. Use the tool designed for this purpose, never a pocket knife.

The maximum untwist allowed at each connection is 1/2 inch. It's easier to sequence the wires property if you strip 1 inch of outer jacket but you MUST trim it back to 1/2 inch before inserting the cable into the connector. Make sure that all 8 wires seat properly before crimping. Look at the end of the connector prior to crimping. There will be an obvious copper "dot" under each of the contacts if the wires are fully seated. If you don't see 8 "dots" it's not seated property and probably won't work.

Answer 2

Start by checking your cabling (read the printing on the jacket to verify that it says at least CAT5). There is no 2-wire ethernet cabling, UTP would be 4-pair and you would need to use at least 2-pair. After verifying you have the right cabling, it could be that:

1. The ends you crimped onto the cable are made for stranded cable and you have solid cable or vice-versa. Improper matching of ends will make for a poor connection.
2. You did not have the conductors cut straight and inserted completely into the end before you crimped it on.
3. You did not have conductors in the correct order.

If your wireless router supports MDI-X (it will take either a crossover cable or a straight cable) then you can make either cable, but if not you will need to build a crossover cable:

Answer 3

There are differnet kinds of ethernet cable ( Cross-over and straight through, The computer will only work with one of those, If you need help with the wires and making the cable look here http://www.ertyu.org/steven_nikkel/ethernetcables.html

Answer 4

I would buy a cable.
Are you connecting to an RJ45 jack?
You should have 4 sets of UTP cables crimped in to complete your cable.

Answer 5

Buy a proper cable! You need two more conductors for it to work! Stop playing computer networker until you know what you are doing!

Answer 6

Reinstall all component.
