Last time I tried, I used an USB2-RJ45 adapter that showed up in the GUI and could be configured normally. If you have serial console cable for the raspi, you can do the basic setup of the interfaces (WAN, LAN) there, highly recommed! You need a special serial (to USB) cable for the raspi, as it has 3.3V on the GPIO pins...

Hi,
  We purchased one USB2-RJ45 adapter. But it is not showing up. Can you explain how to configure adapter?

Which type of serial console cable need to purchase. How to configure interfaces(LAN & WAN) using this?

[chemlud]

The serial cable you best guess buy from your "local" (online) raspi shop, they know what they are doing.

In the serial console there is a menu to assign physical interfaces to WAN, LAN etc. Afterwards you can access the GUI via LAN and do the rest of the setup for the interface.
