Adding WAN port
The board cut section the track going to the built-in antenna (coil on the board), and part of a track udischy in Wi-Fi module and add a screen between the connector / cable external antenna.
D2 - WPS
D4 - second USB port
D10 - WAN port on CPU
Need to unsolder not getting the circuit elements, such as, USB port, LED (D4), circuitry for power supply.
This action turns the device D1 ⇒ D2
The board can be arranged WAN port (P4).
The board involves the installation of a button (SW3) and LED (D2), it is necessary to check.
