Lan cable in the wall bad?

I have cables in the basement that lead to every room in my house, but they are not connected and hidden in the room behind a socket.
Now I have installed a network socket in a room (https://www.amazon.de/dp/B07W4RF4XF/
In the basement I also installed a network socket on the cable and then the network socket in the basement using a LAN cable with the Fritz! Box 6490 Cable connected. If I connect my laptop with a Lan cable and I'm about 2 meters away, I get 200 Mbit / s, but in the room on the upper floor in which I installed the box, I only get 100 Mbit / s.

What could be the reason? Has a cheap cable been installed in the wall?

Can you get 200 in if you Fritz! Box and laptop connected with the cable?

Bi

Yes, could be directly on the cable.

I would send a large file back and forth between two clients and do not measure bandwidth over the Internet.

Ca

If only I knew how very much😂

Ca

Yes, if I hold the laptop directly in the Fritz! Box stuck

Have you connected all 8 wires (correctly)? What does the network card show in your computer for a connection speed?

you can test whether everything is set up correctly. With somewhat more expensive devices, you can also check which speed goes over the cable, but this will probably not be necessary.

to

Connect a client to the Fritzbox in the basement and copy a file to the client upstairs in the room.

Ca

Isn't it that nothing would work if it was connected incorrectly?

to

Not necessarily. If e.g. The four conductors that are required for 100Mbit would possibly go through 100Mbit. But I don't know exactly either. The device for testing is not so expensive that it would not be worth trying it out. Another possibility would be to lay a long LAN cable over the stairwell as a test and to see if you get more speed with it.

Ca

To the test device, do I have to connect one part in the basement and the other part above?

to

I agree.

Ca

I did it, everything connected correctly!

Ca

Could this be the Fritz! Box lie? That it only outputs 100 Mbit / s even though it comes from the same LAN port 200 when you are wrong?

Ca

Still only 100 Mbit / s

to

Then my second question remains open. What connection speed is displayed on your computer? You can see this either in the Task Manager or on the connector (the display flashes differently depending on the connection speed, this is in the description of your motherboard).

to

No, that's not possible. There's actually no standard 200Mbit LAN speed. And the Fritzbox has four gigabit connections. Question: How exactly did you measure the speed?

Ca

I get 200 Mbit / s when I plug in my laptop directly, but when I plug in my laptop upstairs in the Fritz! Box Mash overview 100 Mbit / s displayed

Ca

My only problem is I'm using a MacBook as a laptop

to

That You rely on the ad in the FritzBox Mesh? Do you get 200Mbit displayed from the FritzBox? Let real data run over it. Besides, you should get 1GBit / s as already said.

to

Great. I'm out, sorry:-(.

Ca

No, I did speed tests on Speedtest.net, and besides the box 200 and above I had 100 Mbit / s, but I was surprised because the mesh only shows 100, so my question was whether the FritzBox would not let through.

to

If you have used the same port both times, this is unlikely. For security you can see if a port is set to "save energy". Then it is actually set to 100mbit. In addition, I strongly recommend the copy test I mentioned before WITHOUT the Internet.

Ca

Of course, the first thing I tried was to save the Porta energy, but how should I do the copy test if one computer is Windows and the other is OSX.

to

There are possibilities. You can e.g. Share files on Mac via SMB or use FTP. But I don't know exactly because I'm not familiar with OSX. You have to ask Uncle Google.
