I noticed a very nice tool called “wifite” which I wanted to use on my BPi R1. It has the two Wifi-Antennas plugged in and running as an Access Point (wlan0, no bridging). Wifite can not be started because the wifi-network-card can not be run in monitor mode (instead of master).
When I try to change the wifi mode via “iwconfig wlan0 mode monitor” it says ‘invalid argument’. It was okay for me because i already run it as an Access Point. So I bought a TL-WN725N usb wifi dongle. I created a new interface called wlan1 in /etc/network/interfaces but it can not be set up.
How can I install the usb wifi dongle parallel to the internal wifi chip (ap)?
Thank you for your help! Simon
