    Intel 82579LM Gigabit Network is really slow

    Caj

      hi,

       

      I have this lenovo M92P computer that has an embedded Intel 82579LM Gigabit Network adapter.

      the OS is windows 2012 R2

       

      When I run a internet speed test (speedtest.net), I get 300 mbps (both up and down)

      my internet connection is 1 Gbps (both up and down)

       

      300 is really too slow.

       

      to further isolate the problem, I plugged a " Linksys USB Ethernet Adapter USB3GIG" in one of the M92P usb3 port. I get 900+ mbps (both up and down)

      so it seems that the problem is with this 82579LM chip.

       

      What can I do to get the speed it's supposed to deliver?

      I already tried to turn off any energy saving settings but that didn't help.

       

      thanks for you suggestions
