Ethernet cable connected to my PC but no internet access.

Solved

Hello,

I need help because I tried to solve my problem by browsing through dozens of forums and YouTube videos without success.

The problem is as follows: I bought a new desktop computer with an MSI Pro BP650P Wifi motherboard with integrated network card, etc. I initially connected my PC via Wifi because it was more convenient in terms of organization since the router is quite far from my desk. The issue is that I have a lot of ping and the connection is far from optimal given that I have fiber.

I then connected my PC via ethernet cable this time, but nothing changed. The icon in the lower right corner shows that the computer is connected (no red cross) and even displays the name of the box. However, when I go online, nothing loads. I tested the cable by connecting my laptop with it and the internet worked.

I deduced that the problem was with my PC, so I tried updating the ethernet driver, uninstalling it so that it reinstalled itself, restarting my box, and I also followed all the recommendations from this Microsoft guide: https://support.microsoft.com/fr-fr/windows/r%C3%A9soudre-les-probl%C3%A9mes-de-connexion-sous-windows-2311254e-cab8-42d6-90f3-cb0b9f63645f

Nothing worked, but I noted that when entering certain commands, this appeared:

No operation can be performed on Local Area Connection* 9 when
its media is disconnected.
No operation can be performed on Local Area Connection* 10 when its media is disconnected.

If anyone has any idea if this is related to my problem or any suggestions on what else to do to try to resolve my issue, I'd be grateful.

    Hello,

    Your PC is connected to a Box. Restart it to reconnect. Are you using Fiber?

      My PC is well connected to the router. I restarted it but it doesn't change anything.

    Hello.

    How is your PC connected via Ethernet?

    Directly connected to the router?

    Via powerline adapter?

    Via a wall socket RJ45?

    If your PC is connected via a wall socket or via powerline, connect it directly to your router and check if it's okay.

    I initially connected my PC via WiFi because it's more practical organization-wise since the router is quite far from my desk. The problem is that I have a lot of ping and the connection is far from optimal considering I have fiber.

    For WiFi, you have the mesh WiFi network, for example TP-Link-M4.

      My PC is directly connected to the router with an RJ45 socket. As explained, I also tested this same socket with my laptop, which was connected with the same cable.

      For Wi-Fi, it is directly the router that emits it, and I receive it with my PC, but the connection is quite poor, and I don't necessarily want to buy a TP-Link on top of that, if possible.

        My PC is directly connected to the box with an RJ45 plug

        Just because it works with one PC doesn't mean your RJ45 socket doesn't have a problem, so try connecting it with an Ethernet cable directly to the box and let me know the result.

        I'm having trouble understanding.

        That's exactly the problem I have, my computer is directly connected to the box and it's not working. I confirmed that the issue wasn't with the outlet because I used the same cable that was working on my laptop.

        It was already done, I tried anyway just to be sure but it didn't change anything.

        I realized that IPv4 was not enabled but that IPv6 was prevailing (I don't know if that has an impact)

        As usual, it tells me that I have internet even though it doesn't work at all

    Hello,

    obviously, given the ipconfig/all, it's not a connectivity issue:

    You do have an IPv6 connection to a Livebox apparently, the IPv6 connection to the box is working fine (RA announcement received), but on IPv4, the DHCP is not working and you end up with an APIPA (169.254...../16)

    or your card can receive but what it's sending is not being received by the box.

    To try to fix this, the first thing to do is to run the command netsh interface ip reset

    And restart.

    And there you have it, voilà ....

    But good grief, what a pain those line breaks are!!

      So I tried to do it but the connection is still not fixed

      Should I resend an ipconfig /all command?

      You can resend one, but it shouldn't be very different from the first one according to what you said.

      You can also do netsh interface ip reset winsock

      On the Lbx, are you on the 2.5 Gbit/s port? If so, try a 1 Gbit/s port.

      Unsurprisingly, it still says that local networks 9 and 10 are disconnected when I run ipconfig /all. No changes observed.

      I have also already tried changing the port on the router, but that doesn't change anything either.

      I'm restarting my PC to see if netsh interface ip reset winsock makes any difference, but it seems to me that it's something I have already tested before.

      Connections 9 and 10, we don't care, they are probably old connections or VPNs that are not connected.

      You can get the list by using netsh interface ip show interfaces

      Can you see at what speed it's connecting? Depending on the Windows version, it's not in the same place, but it should be visible in the advanced settings of the adapter.

      I understand what you mean by seeing what bandwidth it connects to. Where do you see that clearly?

      Otherwise, for the netsh interface ip show interfaces, I get this

    Since ipv6 seems to be working at least partially, could you do a ping dns.quad9.net and ping 2620:fe::9 ? If it doesn't work, just to check if the box is receiving the PC.

    And there we go, voilà ....

    But misery, how annoying the line spacing is !!

      My mistake, I forgot to disconnect the Wi-Fi connection. In the end, I have a 50% loss on the order with the second ping.

      The second or the first, it doesn't fit the logic at all ... ?

      The wifi connection, is it a mobile hotspot or the box?

      Can you give me the two pings over Ethernet, with wifi turned off?

      Do it with the -t option

      ping -t thingamajig

      The response times are bad for a fiber connection

      Hello,

      Sorry for the late reply. For the Wi-Fi, I can do both. I can connect directly to the box, but it’s very slow, and sometimes I can connect to my phone, which serves as a modem that is itself connected to the box, and that works better for some reason.

      Here’s what the pings look like with only the Ethernet connected:

      C:\Windows\System32>ping dns.quad9.net

      Not great,

      network cabling is down or network card issue.

      Can you do the same test with your laptop instead (same cables) and let me know what speed this laptop connects at please?

      I think you should prepare to invest in a gigabit/usb3 adapter

    Sorry for the long wait; with the holidays, I was away from home for a little while.

    I tried changing the cable by using a much shorter one that is closer to the box.

    The verdict is that it works; it seems that the problem really was the cable even though I had a connection with the box and that the connection was working with my laptop. Anyway, I’m going to change the cable, and that should do the trick. I’m relieved that the problem is not with the network card on the motherboard, at least.

    Thanks to everyone for helping me, and happy new year!
