My local speed has dropped from 100 to 10 Mbps.

Solved

Hello,

I quickly realized that my ethernet connection speed dropped from 100 Mbit/s to 10 Mbit/s.
Where could this come from? I've tried the following adjustments in my "Realtek PCIe GBE Family Controller" network card: Speed & Duplex set to 100Mb full duplex, WoL disabled. But nothing changed.
I replaced the cables, and that's not it...

Has anyone else experienced this problem and resolved it?

Thank you in advance.

    Hello,
    I'm following up on the subject to say that it was indeed the network card on the motherboard that was no longer functioning 100%.
    I installed a new network card and now it works very well :) 1000 Gbit/s is crazy!!!
    Have a nice day!

    Hi,
    a self-negotiation that isn't working isn't easy to resolve,
    try another port on the box.

      No, I did indeed change the port on the box. To no avail :/

    Hi there

    Connected to what? With which cable reference exactly?

    It's already curious that a Realtek PCIe GBE Family Controller (Gigabit) caps at 100 Mbps

      It's an Asus Prime Z270P motherboard that includes the network card. It's a gaming board, so presumably, it has what's needed for the network. It's a minimum :) I have the option for 1000 Mbit/s if I want, but I don't need it ^^
      For the cable, it's category 6. The thing that worries me is: if the local network was done like the rest of my new apartment, I'm afraid it was poorly done...

      The connection of my network: computer -> wall socket RJ45 -> RJ45 socket in GTL -> Freebox

      Unless I’m mistaken, we can rule out the hypothesis of faulty cables. I had installed personal cat 6 cables before it switched to 10 Mbits/s and it was working fine. I tested it with the Free cables that are supposed to be suitable, and it doesn’t work either... I would lean more towards a software issue. Or maybe the wiring of my local network in the walls... :/
      What do you think?

      Hi buddy,
      A gigabit card connected to a 100 box or switch connects at 100, not more :-)
      After that,
      He has a fbx, if it's an old HD or a crystal, it doesn't do gigabit.

      I know but I can’t guess that it’s an FBX.

    If it connects at 10 but not at 100, it's not a wiring issue but an electronics problem with an interface or configuration.
    If the Ethernet port is correctly configured to auto in the driver, it should be fine.
    If you're using wall sockets, still try a direct cable, but I don't think it will help much.
    Try to borrow a small switch to place between the box and the PC.
    Also, try another PC on the box.

      Ok, I'll give it a try and keep you updated. I have a switch for the TV/console/recalbox ^^

      Well, I tried it like this: computer -> wall socket -> socket in GTL -> TP-Link switch -> Freebox
      I am getting 100Mb/s, but I can't access the internet; I have an error message that says something like "IP address configuration error."

      I connected my PC directly to the router, and I'm still at 10 Mbit/s... :/

    Is it my network card that is failing? :/

      It's hard to say at this level, she's negotiating well at 100 on the switch, but there's no connection, we don't know if it's between the box and the switch or between the PC and the switch.
      We would need to be able to test with another PC under the same conditions...
      The switch is normally connected to the box and the console, and the console accesses the internet?
      We would need to connect the PC to the switch under the same conditions; if the PC cannot access the internet and the others can, then it's the PC's network card that's broken.

      Alright, thanks brupala. The console is indeed accessing the internet. That confirms what I thought. Well, network cards are usually not the most expensive thing.

        No, not too expensive,
        I recommend a gigabit adapter on USB 3.0 that can be reused on other machines if needed.
