content: I bought two sockets, for connecting one end to a cable and then router, and then the other one to a cable and a computer.The sockets and cable are cat 6.(The two sockets need to be connected to each other using a cat6 cable)Thanks

content: Here is the result of a 10 second google.https://incentre.net/ethernet-cable-color-coding-diagram/It's important to know that the wiring is in twisted pairs. It will not work if you do not observe this pairing.

content: Gigabit ethernet is significantly more picky about signal integrity issues like maintaining the twisted pair right up to the plug. Basically its RF - each pair is a differential transmission line. It's really pretty much a marvel of engineering that it 'just works' - and so well now.A long time ago one often needed to use acrossover Ethernet cablein some patching situations but now most switches (all 1000-BaseT "gigabit" Ethernet switches do) automatically select - so a special crossover cable isn't necessary except sometimes on old slow non-gigabit HW that doesnt have a specially marked crossover jack. (Typically this is done for the 'uplink' port on a lower speed switch/router so users don't need a special cable)Use hardware thats designed for Cat 6 and if you're making your own cables, invest a few bucks in a cable tester device..

content: I can't even understand the question. I can't parse the OP. I am not sure what the question is.To me "socket" implies female. It sounds like he may be trying to build an ethernet cable with female RJ45 at the ends.At any rate, to the question "How should I wire my ethernet sockets?" I would answer "you should wire them correctly".

content: You have to wire the pairs correctly to the plugs or the pairs won't be twisted together correctly in the wire which will cause a lot of issues. You should use the 568B wiring standard since that is the most common. Nothing stopping you from using your own colour scheme for pairs so long as you do both ends the same and don't mismatch the pairs but it'll be a potential maintenance headache so best not to do it.Quote from: cdev on January 03, 2019, 03:39:44 pmI've seen this happen with 100Mbps Ethernet as well on a 10m run that wasn't wired correctly. Looking at the interface statistics showed lots of bad packets and it would occasionally drop to 10Mbps only mode. Rewired it properly and could do 100Mbps with zero errors.

content: It's critical for high-speed Ethernet (and arguably even CAT5 wiring) to not only connect the right wires to the right terminals, but also to not have the pairs untwisted for any distance. Guidelines that I have read include that the jacket not be removed for more than 1/2" (12 mm) and that the pairs not be untwisted. Clearly the pairs have to be untwistedjust enoughto be able to punch them down or insert into a crimp-style plug, but care should be taken to keep the cable as undisturbed as possible.With the relatively low cost of pre-made cables (as the OP seems to be talking aboutplugs),it is difficult to recommend home-made Ethernet cabling.

content: Quote from: soldar on January 03, 2019, 03:57:43 pmThat is uncalled for and unnecessarily rude.So why don't you help him out with a few relevant links? Not everyone's abilities are the same. He may have a very slow connection, he may not know what terms to search for, there may be other reasons.If you feel the question is not worth your time then the polite thing to do is move on. No need to be insulting.

content: The way I read the OP's question is that he is in the process of wiring a residence for Ethernet. In one location in the residence, he has a router, the other location he has a computer. He wants to string a Cat6 cable between the two locations and use a wall plate at either end. His plan is to use a jumper cable between the router and the wall plate, and the computer and the wall plate. He needs to know the configuration to use to ensure signals are sent/received correctly. At least, that's what I read into the message.He needs to wire the wall plates straight through and choose either T-568A or T-568B wiring scheme. I'd recommend T-568B to be most compatible with telephony and networking equipment. Information can be found in many places on the Net; here's one:https://incentre.net/ethernet-cable-color-coding-diagram/

content: I useLeviton Quickportboxes and plug in jacks and mine use a phone type punch down connector. (looks like a little blade you press the wire into a conductive holder that grabs it tight, like a phone punch down block) I have a bunch of them, (one example SKU is "Quickport Snap-in design No. 5G108-W" which is a 10 pack of female Cat 5e jacks, 8 position, 8 conductorsMine are labeled Cat5e but they work great for Gigabit Ethernet as well. Have never presented any kind of problem.The boxes will accept different numbers of female Ethernet jacks, (3 is what I usually use.) they are neat, they seem to even tolerate not being connected to the wall okay. In other words you can mistreat them and they don't come undone.Just if you have multiple (like three) cables coming into your box, multiple cable tie the three cables together so its not a tripping hazard. Also use a nylon cable tie so they have strain relief.I would strongly recommend mounting the boxes to walls but sometimes you need them to be available somewhere else, like on a table.Since nobody else brought this upit is absolutely imperative to keep your Ethernet wires away from mains power wires.Don't ever attempt to run them through the same conduits or share boxes with mains power carrying anything.Also keep them away from CATV wires or any other kinds of low or high voltage wires.

content: Quote from: cdev on January 03, 2019, 06:32:34 pmPerhaps that’s becsuse gigabit Ethernet requires only Cat 5.Another vote for the Leviton QuickPort (aka Keystone jack) though, I’ve used them for a few installs.

content: 3rd vote for Leviton. I have used 3 outlet plates for phone, ethernet and cable. Works fine business.
