Hello 151,

Im stuggling with the same network cards, but both ends on my infrastructure now dropped to 1.55Gbytes..
Been debugging this issue for over 20+ hours now.. and have a feeling its related to the kernel module.
I will keep testing next days, hopefully find a solution.. that can help u as well.

My issue seems to be caused by the windows driver. No issues on linux with same setup / network configuration. Windows keeps being stuck at 1.55 Gbit on differnt versions on windows with the same driver.

Update: issues caused on my end was the Large Send Offload (LSO) breaking on the intel driver on windows. Disable Large Send Offload (LSO) resolved it on my end.
