cat 5 question

I have a small lan connected through a Linksys router (BEFSR41), all PC's running Win98SE. I am moving one of the PC's to another room and have Cat5 cable run between the room where the PC is now and where it is going to be. I have installed wall jacks on the ends of the cable matching the color coded wires the same on both ends. I am using a Cat5 cable from the wall jack to the router (same cable that was going to the PC) and a Cat5 cable from the wall jack to the PC in the other room.When I turn on the PC in the other room it is not recognized on the network. My question is should the wires be hooked up differently at the jacks on each end (i.e., some of the colors switched)? Any help would be greatly appreciated.

 

Wall jack to wall jack is straight thru!

Do not try to match a jumper (used from wall to computer).

Most all of these have punch down color codes, or a diagram included on paper . Use those exactly.

Very good info

Good site SSmith

But this link above refers to patch cables.

BillB this link from same site is about wall jacks on down in middle of article.

The wall jacks you have should have these diagrams on them or came with a paper diagram.

Oops!!!!!!!!!

I just reread your message. Missed this before

"(same cable that was going to the PC) "

If by same cable you mean a cable that you used to connect the 2 computers together directly (without the router) then this is a crossover cable and will not work with a router/switch.

Two computers connected directly by a single cable uses a crossover cable. But thu a hub or switch (this router has a 10/100 switch) it is not crossed. So if this is true then get a straight thru regular patch cable. And the wall jacks are probably correct since the other works.

more info

Thanks for the replies guys. I looked at the pages you mentioned, the strange thing is the wiring specs mentioned on the page for 568A & B look different than the diagram on the jack that I am using (at least to me they do). Here is a link that shows the type jack I have, it is a self-crimping cat5e jack. I have wired it using both the top and bottom colored wiring schemes and no luck. I thought maybe seeing the jacks might provide some insight as to what the problem is.

I took care to make sure that the wires were not untwisted more than a half inch, and to make sure the wires were successfully crimped into the jack. As I understand it from the vendor, the ends of the wires do not need to be stripped before crimping so I did not strip them.

I am not a network guru by any means so I am lost as to why this is not working.

Thanks for any help you can provide.

 

Sorry ,probably already tried this but...

What socket have you used on the router?

Make sure its not the uplink socket.If it is the router may be crossing the pairs for you.

Some routers have a switch on the uplink port to change from crossover to straight through.

How many LAN sockets do you have on the router?

 

Babaton,

I am using port 1 on the router I believe. I know it isn't the uplink port as it is used for a Hub.

 

Port 1 is often wired cross-over.

If it is used to connect a hub it is almost certainly wired crossover.

 

My mistake, I am using port 2 on the router to connect to the PC with the problem.

 

When you connect 2 PCs straight to the router with straight through patch cables you can ping right?
If thats the case then your problem must lie with the wall jacks and the cable between them.

I've not used the wall jacks you have before but when I've had problems like this in the past often it has been due to a simple bad connection.

Usually I rewire the jack and use more force when crimping the wires.

Not very technical but in this case brute force might be the key.

 

I believe those jacks you are using do not require a punch down tool. They have a peice of plastic on a hinge to push the wires down into their recievers.
THEY ARE JUNK! I used them on one job and one job only. 1 out of 10 would test good.

Since you don't have a cable tester you could be pulling your hair out.
You may come out cheeper just paying a pro to come terminate and test your connections rather than buying the propper tools.
You need to find someone that does data connections for a living.
Most PC repair shops dont have the proper equipment either.

 

problem solved

Sorry I haven't posted back sooner. I was waiting on a cable tester that I ordered, then Hurricane Isabel hit and I lost power for a while.

I tested the cable with the tester and it indicated no signal being received. I talked to the guy that ran the cable for me and it turns out that he ran two cables, but only ran one of them all the way through both walls. The other one had one end still in the attic and one end up in the wall just above the opening where the other cable comes out. I pulled the second cable end out of the wall to see if perhaps I had mis-matched ends and sure enough that was the problem. I put the connectors back on and the cable tested good so I hooked up the PC and it works great.

Thanks for all the replies.

 

Great that you got it fixed.
