Cat 5e In Wall Cable run not working

[Gronnie]

I just moved into a new rental house that is wired with Cat 5e. I was able to get all the jacks to work except one (of course the one located right by my TV and HTPC, the second most important one, doh!)

 

I don't have any testing equipment so I took some picture hoping to get some input on what is wrong. In the closet upstairs is an RJ45 terminated end, and downstairs by the TV is a punchdown wall box.

 

There's two cables upstairs that it might possibly be (and I'm not positive which on it is), so I included pictures of both.

This looks like its correct! you could wire them industry standard if you want, this will also verify that they are punched down fully and making a connection. Have you punched down or made a wire before?

 

[Gronnie]

No I've never done it before, but now is as good a time to learn as any!

 

Any good tutorials you recommend? Tools to buy?

Well, it is wired correctly, they just used Type A instead of type B. I would get a cheap RJ45 cable tester to check for a line break or something.

[Gronnie]

Yep looks like both ends are wired as "A".

 

The white and blue cable looks to have a "chewed up" look to it that you scan see in the picture halfway between the yellow wire sheath and the punch down block... I wonder if that might be part of the problem.

 

Also, are the wires maybe untwisted too far?

[scottyseng]

that still should be fine (not ideal), but still should connect (Hard to tell from photo...maybe it broke)

Yeah, you'd want the twist as close possible. I kind of stopped using punchdowns myself though.

So I tested the cable and it had absolutely no signal anywhere along it, not sure what the heck was wrong with it.

 

Thankfully there was another Cat 5e that was ran to the same location but wired for phone. I don't have landline phone service so I just rewired that cable for phone.
