INEA 600 Mbps Stagnated at 95Mbps over 30m 5E Cable: Possible Issues and Solutions

Hello, I have a problem that I don't know how to solve. Well, today I raised the Internet operator INEA to 600 Mb / s earlier I had 150 Mb / s to 15 Mb / s probably - something that is not important. The problem is that on one cable there is 600Mbps on the other I have a stagnation up to 95Mbps. Both cables are 5E category, of which one, the factory one from Inea, is maybe 1.5 meters long and I need 30 meters because I have about 30 meters from the modem to the computer. 5e cable 30 meters, I made the plugs myself because they were not factory-installed. The Internet is no problem with the fact that instead of 600 Mb / s I have 95 Mb / s (even on a laptop that received 600 Mb / s via a cable with inea).
How to deal with this?
Is the cable Chinese?
I ordered on Allegro because I had no other alternative in my town. I earned the plugs in a simple configuration according to the guide - Rj45 TYPE A - TYPE A. Cables on each plug in the order of white-green, green, white-orange, blue, white-blue, orange, white-brown, brown.
Where could the problem lie? In the length of the cable, its cheated variant or badly made plugs?

Show a picture of these earned plugs, what kind of wire is this? Some company?

What speed does the network card see?

I don't know if it's a company cable, because I don't know much, but it says CablexPert. The picture shows the full text

The network card sees 1Gb/s, Full Duplex

Since the card sees gigabit, it should be ok. Doesn't this value drop under load?

It's not ok because this cable on the speedtest is 95Mb/s on the cable with Inea speed test shows 600Mb/s

When I made the first cable myself, the 3rd time it worked because it broke the connection. It turned out that the eroticas I bought were not suitable.

Unfortunately, the connection is stable and there is no packet loss :/ Is it possible that one of the wires is out of order and I am not getting the intended speed?

Earn again, only now in standard B and do it more carefully than what is shown in the photos.

I'm no cable expert, but I tried my best
I plugged with type B and unfortunately the effect is the same. 95Mbps on both PC and Laptop.

Maybe the cable is physically damaged somewhere.

Do you have a meter to ring the wire?

And you can see that it's CCA - copper-plated aluminum and not copper.

I don't have a meter, but even if I did, it's practically impossible to measure it. The cable goes from the ground floor to the third floor through a ventilation chimney. Maybe something broke 2 years ago when I dragged it. Well, nothing, there is probably a replacement of the cable, but if I have to play with dragging it through the entire building again, I'm going crazy. I'll let you know if I get a cable of a similar length tomorrow. Fly in 5e or buy 6 right away because it may turn out that I will hit some qualitative scammer

Cable from Bitner, Madex.

And one more question - does the RJ-45 plug have to be special? For category 5e or 6? Does it matter which one?

Well, maybe first I'll start with embracing the 5e plug to make sure that the problem is not with the plugs themselves

@warzych123
These plugs you currently have, when you look at the plug, do they have 2 prongs or 3?
3 teeth are more versatile:

They have two teeth

What are you clamping the RJs with? I'm asking because I've already met people who clamped with a screwdriver. Unfortunately, without a meter, or at least a good LAN tester, you will not be able to determine where the problem lies.

One note - these pairs are unraveled at too much length. There should only be as much as fits in the plug, the cable insulation should be crimped in the plug.

I use a crimper for plugs, not a screwdriver 😄
Tomorrow I will try to buy a plug with 3 teeth and make a plug as God commanded

try this:
- cut the connectors
- strip the wires at both ends of the cable after approx. 5 mm
-On the first floor, short the right pairs, i.e. white-orange with orange, etc.
- on the ground floor, test this short circuit by attaching a light bulb with a battery
If the bulb is not lit, there is a broken wire in this pair.

What you write may indicate that one of the twisted pairs is not connected.

At a short distance (30 m is a short distance), the category of the twisted pair, the type of connector or the type of material does not matter.
More critical is the correct crimping of the contacts, i.e. the right crimping tool and the ability to use it.

I wish you good luck.

Replacing the cables with company ones helped thanks to everyone who tried to help
