This Guide is for a "client to client" setup of the box, we will internally switch Wifi to Eth, so a working computer can access internet from its eth port even if the router signal source is wireless.
Router AP -----> ARM BOX [WIFI internal or usb dongle] ===>> internal eth0 ------> ethernet cable --> client eth port
