0phoi5 Posted June 30, 2017 Share Posted June 30, 2017 (edited) Hi all, I was playing with hoover.pl last night, which works great, apart from when it gets to line 108; (system("$iwconfigPath $interface mode monitor")) && die "Cannot set interface $interface in monitoring mode!\n"; It returns the above die error, with the reason given being; Error for wireless request "Set Mode" (8B06) : SET failed on device wlan1 ; Device or resource busy. I am using a RPi3 with an Alfa Wi-Fi card connected to one USB port. The internal Wi-Fi chip is wlan0 and the external Alfa card is wlan1. I have the internal chip wlan0 connected to my home Wi-Fi, as intended, so that I can SSH to the RPi. However, I believe the issue above is stemming from the fact that, when I run iwconfig, both wlan0 and wlan1 are showing as being connected to my home Wi-Fi. I don't want this; I would like wlan0 to connect to my home Wi-Fi, but wlan1 to stay available to use in monitor mode. I have tried; iwconfig wlan1 down iwconfig wlan1 mode monitor (and/or) airmon-ng start wlan1 iwconfig wlan1 up No luck; wlan1 still insists on reconnecting to my home Wi-Fi and setting itself back to Managed mode. How can I stop wlan1 (Alfa card) connecting to my home Wi-Fi, but leave wlan0 (RPi3 internal) connected to it? Thank you.
