I have connected a cable from my router which has been tested and can transmit the 500mbits.
I plugged the cable into the wall LAN input which runs into a Cat7 cable via a Cat 6 socket.
Up in the room where the Cat 7 wall plug comes out, I also have a Cat 6 LAN socket.
The LAN cable, which ultimately runs into my laptop, also works and could transfer 500mbits.
Nevertheless, I only receive 90-100mbits above, even though the device is connected to the router and transmits 500mbits with the same LAN cables.
Well, then one of the intermediate points is just not able to deliver this speed. If the laptop reaches full speed with each of the cables involved that are not in the wall, then it must be one of the sockets or the cabling inside the wall.
How did you test that? If you plug your laptop directly into the router, is it faster? Possibly. Are you mixing online data rates with local data rates between PC and router.
Are the ports from the router even gigabit capable? And if so configured?
Is the network card of your laptop capable of gigabit?
How do you test the speed? So from where to where? To a server on the Internet? If so, do you even have more than 100mbit internet connection?
I connected it to the same port during the test with the LAN cables with which I had 500mbits
Speed test from the internet.
The ports are of course the same
Cat 6 socket and a draka uc900 super screen 23 category 7 s / ftp 4p wall cable should manage up to 1000mbits
And how is the wall wiring connected to the sockets? Crimped yourself or with a plug?
Exclusion procedure:
PATCH cables used transmit Gbit (i.e. 500MBit tested with a router).
Router and notebook consequently also support GBit-Lan, otherwise you would not have measured 500MBit…
The only cause of the error is the wiring of the CAT7 cable with the CAT6 sockets…
Possibly there's a wiring error on one / all sockets, so that no GBit-Lan is available… For GBit-Lan, Cat5e is sufficient. But all 8 wires have to be connected correctly and the shield has to be connected properly. So if there isn't a switch somewhere in between, which distributes the signal from the router to various LAN ports in the house, only the laid cable or the sockets remain as the cause…
Probably that must be the problem
I suppose so. Can you "beep" the lines?
So if the same ports were used on the router and on the PC, then it can only be due to the cable. You might have to check whether that is wired with gigabit and not 2x 100mbit or whether there's an error / broken cable. To find out, there are either extra testers or if you know the line for sure and know that there's no switch or something else, you can also use an LED and a battery. Then you have a ghetto pass examiner.
A continuity tester would only show a direct current. Gigabit Ethernet is in the megahertz range. There are high-frequency effects that you solder or crimp yourself and that can't be measured with the DIY store multi. If that is the cause of the low data rate, it will be difficult.
A cable break would rather not result in a slower data rate
Thank you for explaining my job to me…

Yes, that's right and so you would be able to detect broken cables or swapped cables.

Correct. 100mhz to be exact. But these problems occur so incredibly rarely that I would rather first check all other possible sources of error before saying that it is something like that. In addition, a CAT7 cable with CAT6 sockets was used. You can't do much better for Gigabit. CAT8 wouldn't really help here either. As long as you stay with Gigabit
If that is the cause of the low data rate, it will be difficult.
That's right, that's why I would first test sources of error that are easy to test. Or not? So a continuity tester…
A cable break would rather not result in a slower data rate
Oh yes? Maybe you should do some more research. This is precisely the most common cause after incompatible network components.
In addition, some used to save and put 2x 100mbit over one cable instead of two cables. It works too. Until you want gigabit. Then you realize that saving wasn't the smartest thing to do. For 100mbit you only need 4 wires. For gigabit, however, all 8 wires. If a wire is broken, only 100mbit are possible. If wire 1, 2, 3 or 6 is broken, then it is even possible that not even 100mbit works.
You can see quite well in the picture:

With unfavorable wave resistances, reflections in the hundred megahertz range can certainly occur on the line. Whether this is the case here (with unconnected wire pairs) can really be neglected. But may lead to beautiful phenomena such as Current flow in a line although it is interrupted at the other end.
I have to admit that I didn't know until now that you don't need all the cores in the
