Switch my connection

Hello,

I am reaching out because I have an issue.

I have a 400Mbps connection with Orange. Everything is fine with my wall sockets.

However, as soon as I add a TP-Link SG108 switch, I am limited to 100Mbps unless I connect the box directly to the switch and then the computer.

So I wanted to know if it is normal that as soon as it is plugged into the wall socket or the box and then goes to the wall socket, it is capped at 100Mbps while without it, I am at 400Mbps.

Thank you.

    Hello,

    Either one of the cables used is not perfect, or more likely, it’s the wiring of the wall outlets or the patching sockets in the communication panel. Just one wire wrongly connected on a socket can drop the speed from gigabit to 100 Mb/s.

    How many wall outlets are in the apartment? And could you send us photos of the communication box to give us an idea of the installation?

    An Ethernet connection between devices is 10/100/1000 Mb/s.

    400 has nothing to do with it; it must be the internet speed of your box.

      Hello.

      I tested each cable and on my own I have 400m when testing the speed. And as soon as I add the switch, I drop to 100m

      I have 4 wall sockets
      Here are my VDI sockets distributing each wall socket



      Yes, the 400 is my box

    Hello.

    It is important to consider that internet bandwidth and local network bandwidth are two distinct things.

    You may have a bandwidth of 1 Gig at home, while your internet connection may be at best 400 Meg.

    The switch is in auto-negociation, so it has no problem negotiating for gigabit, as long as the hardware configuration allows it.

    According to your description, there seems to be an issue with your wired network.

    Was the cabling done correctly according to this standard?

    Hello,
    it would be good if you wrote the units correctly:
    a network speed is in Mbit/s not m, for me 400m is a lap of the stadium, not a speed.
    Then, indeed, it could be the wiring of your wall sockets that is limiting to 100 Mbit/s, there could be one pair out of the 4 that is not working properly or has a poor connection, which causes it to run on only two pairs between the switch and the box, which results in 100Mbit/s instead of 1000 Mbit/s.
    It could also be a negotiation issue of the speed between the switch and the box, which is more troublesome.
    If you connect the PC directly to the wall socket without going through the switch, what do you get?

      Hello

      Sorry for the units

      When I read the computer directly from the outlets, I get 400 Mbit/s, but as soon as I use the switch, it throttles.

        So it’s not the wiring but the switch.
        Try another cord between the switch and the wall socket, another socket on the switch, cut it and restart it ....

    By the way,
    is it a SG108 or a SG108E, which is a bit manageable?

    and ... There you go!
