Hello, I'm new here
I have had the message regarding "Realtek R8125 NIC found" in Fix Common Problems for a few days
Now I'm not entirely sure about the current driver
r8169 RealTek RTL-8169 Gigabit Ethernet driver Inuse net/ethernet/realtek
Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
PS
My english is bad :)
