Cat 5e connection

[gsctt]

Hello,

I have a problem with one of my computers. It was working fine, (connencting to the internet), until the carpet installers pulled the cat 5e jack from the ethernet cable.

I've tried to rehook the jack with both the A and B sequence, shut everything down and back on but still can't connect. I'm anable to ping yahoo or comcast either. The reply is unknown host.

When I ran the cable and set it up about three years ago I remember having problems with the wire sequence and posibly a patch cable. I can't remember if I used a patch cable sequence or how to.

The one I'm having problems with- ethernet from router to wall, ethernet from wall to wall (this is the one), wall to computer.

Thanks in advance to anyone that can help.

I'm confused. There are now only two wire sequences common, A and B, (568B most common). Then there is crossover. If not a crossover, both ends should be wired the same. If crossover, A on one end and B on the other. It is common to error when making patch cables by having one or more wires not fully inserted in the terminal or jack. You need to check that very carefully if you don't have a tester.

Ok, thanks for your reply. I'll check again....how would I know if I have a cross over? I think maybe I do and got it confused with the term patch cable.

The crossover is usually used between two switches or hubs or between a router with built in hub or switch and another hub or switch. Some modems that are designed to go only to a computer may require a crossover to go to a router. Then again, many newer switches and hubs are auto-sensing and don't require a crossover. Try a crossover and see if it works. Sounds like you have a crimping tool, so you are only out a little time and a terminal and a couple inches of cable to try it. A cheap tester is worth the investment($15 or less). It just tell you if your wiring is in sequence and making contact.

"...how would I know if I have a cross over..."
Hold the two ends of the same cable jacks together and look at the color coded wires.
If they match, it's straight wire. If they are opposite, it's crossover.

Here are the two cat 5 end types.
