Router hangs up. RTL8111.

Hello,

I have a router with ROS 3.13.
Motherboard Intel DG31PR with integrated Realtek* RTL8111-GR Gigabit Ethernet Controller. Router hangs up ( It is enough to turn off/ turn on Ethernet (100Mb) to recover router. Thus router rebuts. If to connect router to gigabit switch router doesn’t hangs up. But if to install ROS 3.17, 3.22.. router hangs up even with 100Mb connection. Help please )
