Thanks, convinced my dad he needed a tool to do it properly, he’s the type of stubborn guy who’d rather try for 4 hours instead of going out and buy a tool. Great explanation!

I have one of those testers, took me a while to realise that the number 2 led on the remote unit was not working. A frustrating amount of time was spent looking for a fault in the cabling before i finally checked the tester with a known good lead. Swearing was heard!

I watched several of your videos before designing and laying out the electrics for my new garden office. That is now installed and tested by an electrician. This time I am completely confident of being able to run an ethernet cable out there and plug in a socket at each end. Thank you so much for all your help. No fluff or faff, just clear instructions with emphasis in the right places!

My god, where were you when i was an apprentice! All your videos have me captivated. Great explanations and practical applications. Thank you.

Thank you. These videos help make up for the many terrible teachers out there and allow students pass their exams.

As always, a very CLEAR demonstration from John that blows the others away. Wanted to check how to use punch-down tool, other videos no matter how well made didn't make clear, hand in the way, not close enough, how does the tool push and cut, which way around to position; ah har, play John's video and crystal clear to me now.

Just beware there are two standards for wiring RJ45: TIA/EIA 568 A & TIA/EIA 568 B. The A standard provides backward compatibility with phone wires. The inner 4 wires are wired the same (orange stripe, blue, blue stripe, orange) for both phone and data. The B standard is more common, perhaps because it is not backwards compatible with phone wires. Plugging in a computer to a Network jack that is actually wired for phone can damage your computer when the phone rings. While using Cat5e jacks for both data and phone may be convenient, there is no visual indication if a jack is for phone or data. Connecting a computer to a RJ45 jack that is wired as a phone might damage the network card when the phone rings.

good vid John, I get to plus you again :) I'm also really glad you mentioned the twists as close as possible, so many people forget or dont know this, they treat it like a plug and untwist the lot, so well done

Instructions unclear . . . Connected the 5cats to the mains. . . . I guess feline in is not the same as mains line in. . . . . . .meeeeouch

Keep up the good work JW. . . Been following you for a while now. . . Love the vids

[philipbramley]

thanks clear and concise, enabled me to mend a socket pulled off the wall with the connections gone , ( a £7 tool and 2 minutes and it was done , thanks john

[MalagasOnFire]

Nice job on the inserts with the tool and good advice on keeping the twisting. again get a decent insert tool for heavy dutty. although the cat6 here is getting more usual the cat5e is more easy to crimp / insert.

[marcel]

Well done! I like the detail in your video, i can see now how it actually connects, gonna try this soon.

Thanks, another clear and instructive video. Btw the thumbnail youtube picked makes it look like a Darth Vader helmet is nuzzling your face.

interesting that in England/UK you have the little shutters over the RJ45 socket opening like the hot terminal on your plug outlets. which would keep any dust.dirt out . as far as I know, we don't have the shutters on ours in the U.S, but I am not up o the latest network developments here .

[adriand]

I appreciate the video John, its very helpful

But I’m surprised that no one seems to make a simple face plate with a female plug connector on both sides. So one can simply buy a long enough cable, run it in the wall and then plug each end into the back of the face plate and fit it to the wall box, so fast and straight forward no need for wiring or special tools

If someone knows where i can find these please reply

[nithyanandarajah]

Thank you. Excellent video with very clear commentary

[taral]

Thank you for the informative video... I don't know why people even disliking this video???

[UsefulWisdom]

Very interesting video but what if I was having an bad day and put the wrong wring in a terminal. Can I simply pull the cable out without causing any damage to the wall socket or the cable?

[chrismcnally]

Thanks for making the second video on RJ45 termination

Only four out of the eight wires are used for 100Mbit connections, so it's possible to use one cable for the two sockets (two wire pairs per socket). This doesn't work for 1000Mbit though since it makes use of all eight wires in the cable but for 100Mbit you can get two independent network connections with just one cable.
