Acces point with External Antenna on the DUE

Hello everybody,

I am trying to find a WIFI shield for the Arduino DUE, which can setup an acces point and connect with an external antenna. I have a project for which I now use a Raspberry Pi connected to an Arduino. I want to replace the Raspberry Pi with a WIFI shield due to power consumption.

Does anybody have a suggestion? I tried to google it a lot, but most of the shields either had no external antenna or no AP mode.

Thank you for your help!

Wouter
