OpenWRT - Install & Configure USB to Ethernet Adapter - Raspberry Pi

In this video, we are going to install the USB to Ethernet adapter on the Raspberry Pi and configure it as a WAN interface. The best improvement of the Raspberry Pi 4 is that it has USB 3.0 and true gigabit ethernet port, which should be good to setup as WAN and LAN.
For this tutorial, I used the D-Link DUB-1312 USB 3.0 to Gigabit Ethernet adapter but any of the adapter will work, no matter it is a gigabit ethernet or fast ethernet.
If you have a monitor and keyboard, the configurationcan be done easier. Else, SSH connection works just fine. I am using the Raspberry Pi 4 and due to it is the snapshot version, LuCI is not pre-installed. Below is how we do it:
1. Change the LAN IP of the router and connect it to the main network to have a working internet connection
2. With the working internet connection, install LuCI using CLI
3. With LuCI installed, configure the driver for USB to Ethernet adapter and setup WAN interface. Package used kmod-usb-net-asix-ax88179
