Cat5E phone line converting it to LAN; how?

[Morphx2]

So I just realized that the builder installed Cat5E lines for the phone lines in the house, which arent used at all; we have no phones. So I would LOVE to switch it to use the internet instead for nice LAN speeds!

How would I go about this? I have the crimper tool already, is it just a matter of putting the end connector on it with the correct colors?

Would it be cable modem -> router/empty ethernet space -> wall?

Since it's basically just point A to point B, can't I use that as the cable to connect downstairs to upstairs? Router to point A jack connecting to point B through the wall, then to my computer?

So router -> power line -> power line -> downstairs jack -> cable going up the wall -> upstairs jack -> computer using ethernet

Boom, i have internet Its only at 37 Mbps instead of my 100 Mbps, but I am sure that is because of the powerline connection

I guess problem solved?

I couldnt of done it without all of you, thank you all so much!

So the internet DOES work, but something is fishy!

Connecting my laptop directly to the router, i get a nice gigabit connection and 100 Mbps download (max my Comcast does).

Connecting my laptop THROUGH the wall cable (laptop -> jack -> wall cable -> jack -> router), i do not achieve a gigabit connection. The light is amber which shows a 10/100 connection. Also, i never can achieve a 100 Mbps download. It goes anywhere from 30 to 75.

I am unsure why the connection is slower. Maybe I hooked up the jacks wrong or it is the cable in the wall?

Note: The downstairs gang box does have TWO ethernet cables going into it. One of them does connect to the upstairs (which is how the internet works) and the other one does not connect upstairs (I suspect it goes outside). I am not using the one that does not work obviously.

Router is a Netgear Nighthawk R7000

I thought about dropping a new ethernet line, but i can not remove the gang box in the wall 🙁

Upload speeds are always fine too.

If the Ethernet cable that you are using has four twisted pairs -- like CAT5e is supposed to have, then you have crossed one of the wires on your connection to the wall connector.

I will assume that you do not have a CABLE TESTER that makes it a very simple task to check in wall cables and patch cables.

Look at the individual wires at each end where they attach to the connector and insure that both use the identical pattern, 568B is normally used, but as long as the connection is identical at each end it should work for such a short run.

If they are connected correctly, it is possible that a wire is damaged from a hammer strike or nail perforation during construction, although I think this less likely than a crossed wire.

I used two Jacks from Loews, so they should be the same. I will have to double check later tonight though. It does have four twisted pairs too: green, brown, blue, and I forget the other color offhand.

Maybe home depot has a cable tester and I can pick one up

They probably do. The other color is orange. Once you run enough cable you have the mantra: orange/white, orange, green/white, blue, blue/white, green, brown/white, brown stuck in your head (that's the code looking down from the top of the patch cable with clip down).

The jacks from Lowe's are mostly likely Leviton and they have the color pattern printed on them -- but they have both 568A and 568B printed. As long as you used the same on each end it will work fine, but be sure to use the little wire pusher to get the wires all the way down into the metal pinch connection on the wall plugs.

There is a short with the 7-8; which are the brown wires. I am going to double check the jack upstairs. I think that is the problem. Gotta wait till I put the 2 yr old in bed first, shes watching netflix 🙁

Fixed 7-8, and boom. Full internet speed

You sir, are my hero!

And the reason it was limited to Fast Ethernet (100Mbps limit) was that uses wires 1,2, 3,and 6 of a CAT5e/6/7 cable. Wires 7 and 8 (brown/white and brown) are needed for 1000Base-T.
