[SOLVED] new cables do not work

vmandal · 09-06-2007, 07:07 AM

I have to add a new computer to my network. I have a switch, dsl router.

I simply connect that all the wires from each machine,and the router to the switch and my networking is done.

All this was fine till when i got a new bit long (about 14 meters) wire. The wire always gives me "request time out"... But if i replace the new wire with a old one it works fine.

I have tried changing the rj45 connectors, and also that whole damm wire but the problem still exists.

I have also checked the color combination of the wires .. they are exactly same as the old ones!

someone please give me a hint where and what to look for

Many many thinks in advance.

i guess my wire type differs.. both cat-5e but old wire is CM/CMG and new wire type is (probably) UTP.

does wiring combination also differs depending on type?

(i am a newbie in n/k)

Well, it seems clear that something is amiss with the cables, so about all I can suggest is looking at these links. If the cable is CAT5e, you have the right stuff.

OLD WIRE COLOR Combination (which is working some how):
(see pin 4,5,6 )

Pin 1 White/Orange

Pin 2 Orange

Pin 3 White/Green

Pin 4 Green

Pin 5 Blue

Pin 6 White/Blue

Pin 7 White/Brown

Pin 8 Brown

Actual - the way it should be:

Pin 1 White/Orange

Pin 2 Orange

Pin 3 White/Green

Pin 4 Blue

Pin 5 White/Blue

Pin 6 Green

Pin 7 White/Brown

Pin 8 Brown

Now the big question: Do i need to change the change all the old wires to the actuall combination?

setting the new wire combination to actual one did it.

Pin 1 White/Orange

Pin 2 Orange

Pin 3 White/Green

Pin 4 Blue

Pin 5 White/Blue

Pin 6 Green

Pin 7 White/Brown

Pin 8 Brown

....now both mixed wires are working fine together.

Thanks everyone for the thoughts

Glad you got it going. If I had a nickel for every cable I've rewired after the "professional" cable installers got done, I'd be rich. It's easy for them to get screwed up.
