F^*#in' Ethernet Cable!

So, I finally got around to terminating the Cat5e cable that I had run through the basement ceiling and wall, to connect the BD85 to the router. Wouldn't you know it - can't get a signal. Nadda. I changed the plug and jack at each end a couple of times. Square root of sweet F.A.:mad:

I thought I was careful when I installed the wire, before putting up the wallboard. Perhaps not careful enough.

Problem is, it's an older house and the ceiling/floor joists are only 8", so I didn't want to cut into them and run conduit. There's no way I'm going to be able to fish another piece of wire through now.:(

The only saving grace is that I haven't installed the baseboard molding yet, so I can run another wire behind that. Sometimes, it pays to procrastinate.:p So, I made up another cable, ran it beside the wall and connected the BDP. Works perfectly.

I suppose the lesson here is to check wire for continuity before covering it up - especially wire that is as fragile as Cat5e.:eek: I should know better than to ignore Murphy's law.:eek: I'll probably remove the connectors from the dead wire and check continuity with my multimeter before I write it off completely, just to be sure. I assembled a couple more ethernet cables that worked perfectly, so I just can't believe that having tried several plugs and a couple of jacks, that it's my assembly that's at fault. We'll see...

Seriously, I have no life.

Did you have to pull hard on it when you fed it to that room? Does it have to cross metal at a sharp angle, like heating ducts, an I-beam, etc? Maybe you could check continuity and if pair 1 (blue) is bad, use pair 2 (orange) as pair 1 and pair 3 (green) as pair two. You only need two pairs for ethernet, anyway.

If you didn't test the crimps - it's very easy to f it up. I'd just try to re-crimp the cable on both sides. Be very methodical and careful this time :D

That's the thing - I didn't have to pull hard at all. I had torn down all the old wallboard from the ceiling and walls, so I had open space to run the cable. I didn't really have to put tension on the cable at all. No ductwork or other metal objects.....actually that does raise another possibilty. While putting up the new wallboard, a drywall screw could have possibly pierced the sheathing. If the cable is damaged, I guess what caused it is purely academic now. I'll see what's going on when I check the continuity.

Thanks for the tip about just 2 pairs being required for ethernet - I didn't know that before. Or, if I did know before, I'd long forgotten.:eek::D

I found out how easy it is to screw up the crimps with my first couple of tries. :D However, once I mastered it, I'm pretty confident in my crimping.:rolleyes: So, I'm fairly certain that I pooched the cable somehow. Of course, I don't have an ethernet cable tester, so I can't make that statement with absolute certainty. I'll report back later, after I check the cable continuity.

Do you have a multi-meter?

Yup.

I was going to be sarcastic and say that I was just going to stick a couple of strands into a wall outlet and grasp the other ends with wet fingers...but I won't, because I'm too nice for that...:D

I suppose you want me to do that now, don't you.;)

I've been through all of this. I know your pain. What kind of connectors are you using? I find the ones that allow you to push the wire all the way through are easiest to get right. I have also had very good luck with the tool-less keystone jacks from Monoprice.

Also, for future reference it is good practice to put nail plates anywhere that wires are less than 1 1/4" from the edge of the stud.

That's the jack I'm using.

I'm using these RJ-45 plugs:

They worked fine on a couple of cables that I made up, after a couple of shagged up tries.:rolleyes:

Yeah, I used nail plates on my studing. If I did pierce the wire with a drywall screw, it would've been in the ceiling. I never put any plates on the strapping - didn't think I'd need to. :rolleyes:

I use they guys. Check out their sale items for some great buys.

I recently ran Cat6 throughout my house. A little bit different in the termination, but not bad. It's a tough lesson to learn, but you ALWAYS test your terminations. Many a contractor has gotten burned by not testing.

Oh, and buy a good punch down tool. It's worth the extra money.
