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
