Internet Connection Issues: LAN Cable Next to 230V Cables - Possible Induced Voltage?

Hello
The problem is as follows, I put a bundle of wires next to me on the wall (under the plaster), including 230V and LAN, TEL, TV, I have just earned the ends and put the RJ45 on both sides clamped in the same way (without cross). I am connected to the internet but the pages are not loading. Like a link on another cable, everything works "shortly". So I changed the order of the wires thinking that one wire is damaged and put the RJ45 terminals back in. (ISP only uses four wires) The router established the connection faster but the effect was the same. Internet connection is available but no transfer. The twisted pair is with a screen that I have not connected because I have RJ without plates. Is it possible that such a voltage was induced or just the current is so strong that the digital signal does not flow on the twisted pair?

Start by checking the tightness of the cables and the sequence.
As for the fact that running the power and LAN cables side by side is a colossal mistake - there is no doubt.
At 80%, the problem will be this.

PS
What is the UTP / FTP / SFTP cable? Does it have some screen though?

PS 2
Isn't it better to switch to wireless technology? Without forging walls and the cost of cabling, cans, etc?

PS 3
What if you turn off full duplex and limit the speed to 10MBit? Is there a connection? "The pings are flying"?

this is a cable https://obrazki.elektroda.pl/9392925700_1358369084.jpg F / UTP insulation screen with wire foil and only 4 pairs of wire

The order in which you clamp the wires is very important - Link.

The problem is that this cable goes to the router through the hall and the computers are wired. there is a connection (displays Internet Access) there is no "triangle" on the signal icon.

You are a bit hard to understand without having the web in front of your eyes.

in another apartment I clamped a loose cable when I was comfortable and the internet works there without any problems. I went brown, blue, green, orange. In my opinion, it does not matter, as long as not to endorse the order.

Oh ma, ma, and it's great,
If you take any 4 wires from a twisted pair and tighten it, the results will be as you can see for yourself.

You can't check (ping, or some other tool) - how and if signals are going through the cable? The router's lit LED is no indicator of the quality of the connection.

Either tighten according to the standard, http://www.ertyu.org/steven_nikkel/ethernetcables.html or if you understand what the point is, tighten according to your standard, but certainly not "any 4 wires in sequence".

When I connect the cable, I can see it which is the same as the internet, except that websites do not work. When I disconnect the cable, I have a connection to the router, but I get a triangle and the inscription no internet connection. I guess that's understandable. If the cable was broken, I would have information about it.

Enter the colors of the cables on the pins on the plug.

Why do you question the opinion of people who deal with this on a daily basis? You do it contrary to art.

The cable is called twisted pair for a reason, the wires are specially twisted in the factory in such a way as to minimize electromagnetic and radio interference.

If the cable connection is to work, please make it according to specific standards.

Are you sure you have a shielded twisted pair? because from what I know you can still get on sale without a screen, and then you will definitely not get communication and I support the opinions of the previous speakers, you can not connect as convenient for you, for example, the fact that then you can confuse the order, check the RJs carefully, sometimes the crimper does not tightens the wires well, the pins should be equally pressed and, if possible, all the wires should be of equal length so that you can insert them correctly in the RJ, one shorter one does not reach the wall from the side of the pins and there is no connection, I hope this will exhaust the topic

You are wrong here. UTP will also meet the author's requirements.

Conducted next to the mains cable! For a long distance! - I dare to doubt.

However, the author of the post wrote that the screen is there - so there is a chance.

The problem is that:
- the author of the post cannot use tools such as PING.
- we do not see a picture of how both ends of the cable are made, in particular, we do not know whether the connection is physically correct, what is the ending - socket - or plug?

The author of the post could regret PLN 20 and buy a cable tester (or borrow it from a computer service), he would not have to ask anyone to check the correctness.
The fact - that a physical connection does not always mean that two devices can be networked - especially when the cables are placed together with those from the mains.
In my company, employees used to lay cables this way (UTP instead of FTP) - and now they can only be used for telephone, because despite the short distance (about 10-15 m), it is impossible to establish the correct connections due to interference from the power network - or at 100 or 10MBit in full or half duplex. Also despite the fact that the tester shows the correct connection of all 8 lines.

You probably saw little in your life, if it is not a transformer station, a hall with engines or other heavy machinery or a radio transmitter, you do not need to use FTP cables. The second thing is a poorly made installation on FTP cables (ungrounded cabinet, no FTP patch panel) causes the opposite effect, the screen "does" then as an antenna and collects all electromagnetic interference from the area.

I invite you to Łódź, Rzgowska 142 - I will show on a live example that UTP does not always work - even though there are no transformers, halls with motors and heavy machines. UTP did not work and that's it.
I put the UTP in 1000 other places and there were no such problems. Unfortunately, sometimes it is so - and since it is an unshielded cable - it is hard to blame. When laying the net, you should pay particular attention to what the cables are lying next to.
And don't be bullshit that it doesn't matter. Maybe you do 100 installations and it won't matter, but on 101st it will.

Here I agree with you - the mere existence of a screen will not guarantee the correctness of the connection. You should use this screen skillfully.
After all, the shield in the FTP cable is used not "for eggs" or "to make it look professional" - only for a specific purpose.

The question is what is the cause of this, the electromagnetic field or the quality of the cable. Everyone has their own experiences and it is not worth doing auctions here.
In my opinion, laying FTP in the apartment is not a good idea and returning to the thread, the reason will be rather the incompetence of the author.

I have not said that anywhere, I have been working in the installation industry (low current) for over 10 years.

I respect the experience. However, I wrote exactly:

As for putting FTP at home - how is it different from putting in at home?
Sometimes a house is bigger than many companies.

The company I mentioned (as an example) is a total of 2 rooms upstairs and a lounge downstairs. A size smaller than many homes.
The fact that I did not obtain (and someone else checked it) a computer network connection between the ground floor and the first floor (the cables go quite "inconveniently") may only result from their wrong routing (including power cables). I am not talking about cables for lighting rooms or for a single socket - but a whole bunch of cables going to the fuse cabinet. Unfortunately, the builders who laid the cables didn't care. The mere fact of replacing the cables did not cause anything - because they laid the new cables the same way.

Only a complete change of the connection topology and routing the cables according to our guidelines allowed to obtain the connection.
The old cables still exist - maybe just as proof - that I am right
The physical connection with them is correct - the tester indicates the correctness of all 8 lines. Nevertheless, the connection of any two network devices through them fails.

Life surprises us and I am aware of it often.

I am not as handicapped as I seem to be I can check ping but I don't want to. I will get a cable tester tomorrow and check the continuity of the wires and the correct connection. I asked my friends and they say that at this distance there is little likelihood that there will be interference, although if it turns out that the veins are ok, the screen can actually induce a lot. The order of the colors is important when you make a masquerade mask and for yourself it is one mushroom for your home. For now, there is most likely a badly crimped tip, it remains to be seen.

There is nothing to brag about laziness. You can only alienate forum members who want to help you find a solution to your problem. But since "you don't feel like" .....
Maybe the moderator will not notice it, because this approach breaks the forum rules.

When you do it, then you have to do it.

This is where I end my help, because I just don't feel like it. \

BTW. Standards for structured cabling, and in particular for high-voltage installations (such as lighting with fluorescent lamps), are not designed just for the sake of the author's well-being or out of boredom.

If you know better, why the hell, to put myself in such an ugly way, do you turn our big ... butt? Do as you see fit, for me you can install even coaxial cables, this forum is for people who need help, but are also able to follow other people's advice.

I have in the company where I work; located 130m of UTP cable in a cable tray (metal), along with a dozen or so 230/400 V power cables. They supply various devices (welders, compressors, lighting and whatever comes to mind) and I have never had a problem with the connection. The fact is that everything is connected according to the standard.

hands drop ...
THE ORDER OF COLORS IS VERY IMPORTANT! i.e. more precisely:
If you already insist that you want to make the colors your own, do it, but PAIRS HAVE TO BE PAIRED! It is very important. The pairs are twisted so that the cable has the appropriate wave impedance, low attenuation, low reflection, high resistance to interference. So you can change green and brown, but then you have to change white-green to white-brown. Clamp according to the standard, and everything will be ok.

This is not standardized.

For exact requirements - I suggest referring to the TIA / EIA standards.

I found a certain "abbreviation" in Polish.
1. The minimum bend radius of the cable is four times the cable diameter.
2. The pairs at the plug should not be unscrewed over a length of 1.3 cm.
3. Network cables should run more than 30.5 cm from the twisted pair.
4. A distance of 1.02m should be kept from transformers and motors.
5. If the twisted pair is placed in a metal guide tray, the minimum distance from the power cables is 6.4 cm.
6. If it is necessary to cross the power cables with the twisted pair, they should be arranged perpendicular to each other.

The fact that it works for you - does not surprise me at all. Many devices operate beyond the requirements of the standard. For example, the Atmega 16MHz chip works without any problems with
at 20 MHz. However, the manufacturer does not guarantee this (because it is beyond the standard).

If the network works for you - it is not 100% certain that it will also work for someone else. It may or may not work.
So your "solution" goes a long way from the standard (so to speak).
