Fly Kan CU200 USB 3.0 to Dual Port Gigabit Ethernet Adapter NIC w/ USB Port

The Raspberry 3b+ intergrated Dual-NIC Network card driver. If you are not sure of that the Dual-NIC Network card's working satus, Pls check it by the following steps.

Note: Connecting both ports to the same network switch may lead to unpredictable results. We recommend this product be utilized for dual-homed or multi-homed host systems or as a 2-port network switch; one port connects a computer to a network and a second port shares a network connection with another computer multi-homing.

1. ifconfig -a--Check available Network cards.
