Intel 82579LM Gigabit Network is really slow

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

Hi Caj,

Thank you for the post. Please make sure you are using the latest drive

 

for the NIC, it is recommended to contact the system vendor for the latest driver.

You may also refer to below link on the advance property setting,

 

try make adjustment if this will improve the link speed

I've solved this problem. Mine was defaulting to 10/10 when this setting was on auto. I made this one setting change, and my network speed is normal. (1 GB).intelslow.JPG
