Hi everyone,
I have installed x86 OpenWrt 19.07.3 (r11063-85e04e9f46) on my hp 800 g1 mini PC. It has intel i217LM network connection.
The problem is when the network speed above 500mbps, this intel i217LM card will stop working, after a few second, the network card will come back.
I found this problem when I test my network speed. I tested many times, the intel i217LM will stop work around 450-500mbps. The detailed log shows below: I start speed test around 586s

The intel i217LM card works well in windows 10, which could reach around 900mbps.
So, is there any solution about this problem.
Thank you very much!
