Network throttled to 10 Mbps

Solved

Hello,

My connection has suddenly been throttled to 10 Mbps, and I don't understand where the problem comes from. I've always been on auto negotiation, and the connection becomes impossible when I switch to 10 Mbps; it works. My provider tells me it's a cabling issue or a problem with my network card. I've already tried with two different cables, and it doesn't change anything. If you can help me, that would be nice :)

    Hi,
    How do you measure that?

    Actually, I lost my connection because my network card automatically disables itself for some reason. When I went into the options for my network card, I changed the speed & duplex setting that was on auto-negotiation to 10 Mbps, and the connection came back. If I switch it back to auto-negotiation or 100 Mbps, the connection disables again. Sorry if that’s not clear, and if you need more information, just let me know. Thank you.

      Ok,
      I think we need to change the network card.
      You can invest in a gigabit/USB 3.0 adapter.

        I don't think I have much of a choice...

    And by running a connection test on Speedtest.net, I obviously don't exceed 10 Mbps when I should be having 200 Mbps.

    Hello,

    Have you tried uninstalling the driver for your network card and then restarting the computer?

      Hello,

      Yes, I uninstalled and reinstalled it several times last night, I even tested it on another hard drive and I have the same problem. It’s strange when I set my card to auto-negotiate or at 100 Mbps, the little globe appears in the bottom right, I see that the internet identification happens for 1/2 second and then disappears as if there was a loose connection. I've been having this problem for 10 days now. I'll try one last thing—testing the connection speed on a friend's computer to make sure the problem isn't with my provider since I recently changed modems, but according to them, the signal is good; the problem comes from my end.

        If you can test your Ethernet connection with another computer, it will help rule it out.

      Reminder:
      Even though the driver configuration settings allow for configuring the speed and duplex of the connection, it is not Windows or the driver that negotiates Ethernet speed; it is solely handled by the hardware of the network card and that of the switch on the other end (or the other card in the case of a direct connection between two PCs or another device).

    I just tested it on a friend's laptop and everything is fine, so the problem comes from my network card, which disables itself above 10 Mbps since I've had this ASUS Z170-A motherboard. I've had nothing but problems, so I'm going to invest in an adapter like you suggested. I tried changing many settings on the network card, resetting the IP thanks to some tutorials, but nothing worked. Thank you for your help :)

    It does seem to come from your hardware.

    You can try updating the BIOS of your ASUS Z170-A motherboard.

    And the drivers for your network controller:

    Otherwise, you'll probably need to change your hardware.

      As mentioned above,
      the driver does not intervene in the speed negotiation; it is entirely done by the hardware of the card, the ethernet controller.

        I believe you, but I don't know much about it :)

    I have never updated the BIOS; I'm a bit hesitant to do it. I finally bought an adapter, and it works great. https://www.anker.com/fr/products/variant/aluminum-usb-30-to-ethernet-adapter/A7611011 However, I would like to know if I might lose performance compared to an integrated network card? I just tested my connection:

    UPLOAD Mbps

      No, you won't lose bandwidth as long as you connect it to a USB 3.0 (blue) or a USB 3.1 (with USB-C adapter) port.
      On a USB 2.0 port, it would work, but the speed is limited to 480 Mbit/s (USB 3.0 is 5 Mbit/s over USB).
      To really test it better than over an internet connection, which is often more limited, you even have cable; apparently, not fiber, you need to test locally with 2 gigabit PCs and the iperf software.
      There you would really test your network card(s), not your internet connection.

    Yes, I was scared when I plugged in the adapter; it didn't recognize it right away. I opened it via the new device, and it recognized it immediately, fortunately for me ^^ I plugged in the adapter into 3.0; what a difference compared to 10 mb/s! My downloads are fast again, lol. A big thank you to you, Brupala, and to the others as well; it's nice of you. Have a great evening :)))
