    Hello

    I'm using a Lenovo Legion 5-15ARH05H with Windows 10 21H1 and after checking the network properties I can see that the connection is set at 100Mbps when my Internet connection is 1Gbps. If I manually set under Speed and Duplex the 1Gbps Full Duplex option every single time I restart the PC, it gets connected under 1Gbps. If I shutdown the computer the connection is set at 100Mbps again.

    Is there any kind of fix to this issue?

    Thanks

    Try updating the realtek lan driver to version 10.47 which was released a few days back.

    At the moment it works with the newest drivers. Let me watch it for the rest of the day and I'll be back tomorrow with the results

    Thanks!

    It just get temporarily fixed if I unplug the Ethernet and I plug it again. I don't understand what is going wrong with the connection

    Try a hard reset in your router?

    The router isn't affected as the other computers connected are working as usual.

    Make sure the network card and patch panel your connecting to or the the switch support 1GB speeds.

    If Auto Sensing fails (can be of many reasons, including flaky cables/plugs), you can still set it to 1Gbps Full Duplex by hand.
