Setting up an Network

[TheWhite]

Hey Everyone, so I've got a quick question about networking. I decided to make things a little nicer in my home office. I decided to run cable behind my dry wall, and into wall outlets, to make things nicer while I had it down to the studs. 

 

I have 5 runs, all under 50feet. 2 going into my office, 2 going into a new Req room, and 1 going straight upstairs to the kitchen. On the end in the basement, they all terminate into RJ45 Connections to plug directly into a new Switch. On the other end in the rooms, I have them terminated into wall outlets, to keep it neat. 

I used a line tester and got signal across all lines, 1-8 on the RJ45 side, and 8-1 on the Jack side. (I assumed this was correct as both ends are coded in A). But, when I plug in the computer upstairs to the wall jack it won't detect an internet connection.

 

*Just so you know, I understand that the standard is normally B when creating wire, this is my first time running wire, and I used A like a noob instead of B, but I made sure that both ends of all lines are coded as A.*

 

Thanks,

As long as both ends are pinned the same, the order doesn't matter. You could invent your own order if you wanted to. 

Do the other wall outlets work? Is it just the one that is having issues? 

If all of them are having issues, then you may have wired them up wrong (possibly in the same order, but in reverse) 

Cable testers sound read 1-8 on both sides. (ones that I have used, at least)

Sounds like what you've done is A on one end and the reverse of A on the other, the cable tester should be going 1-8 on both ends.

Thank you both, I believed the same thing when I was first putting the lines together. But for some reason, my brain was thinking that the 1-8/8-1 was correct. Because the wall jack had to flip the connection to marry it with a cable from the wall to the computers.

 

Clearly I was overthinking this whole process. Good thing it's only 5 runs. I left lots of extra cable on the end next to the router, so I'll cut and try to swap the ends see if I can make it work! LOL

 

Thanks for the help.

Easy mistake to make, really. Hopefully it works after.

also - you cannot use a normal patch cable from your wall plug to your devices (those are B), so you will have to make your own patch cables too or buy some T568A cables for plugging in all your stuff to the wall  else you will end up with a hell of a lot of cross-over cables  

 

You might as well just reconfigure it all to T568B when you have to change one of the ends anyway.

You can mix A and B (or any other combo), as long as the pins are 1:1. The issue comes when the pins are in different positions on the ends of the same cable. 

Using B patch cables will work fine.

Maybe I should have written should not instead of cannot (due to interference on Fast Ethernet, in theory)

I really dont know where I got the part with cross-over cables from, I must not have been thinking straight(through) (get it?   straight-through )

Yeah, it's generally advised to use the same pattern throughout a network, just so that you don't have to check each cable for which pattern it is using. As long as both ends of the cable are the same, the pattern doesn't matter (:

I generally use B, as it's pretty much industry standard now. If anything, it would be easier if the cables would only work in a certain layout, so there's not multiple standards.

Thanks all, Sorry I didn't respond sooner, I hate when people leave without a conclusion. 

 

I went back, and checked and you where correct, after rechecking all my lines I had 2 with errors. I think I may have been looking at the Horizontal spacing of the Lines, and forgot that the clip itself is a 3D item, so I forgot that I had to pair the end on the Z access as well. (I hope that makes sense). In the end I figured it out, cut the tips off and re-capped the lines and got everything working, including the lines between the Router and the Wall Jacks. 

 

As for InVis, I also made customer lengths for the Computers as well, just to make sure everything was good.
