I’ve a problem with airgeddon. actually whenever i try to set my network adapter to monitor, airgeddon says your network adapter don’t support monitor mode. i checked at terminal and parrotsec live boot from pendrive also and the monitor mode is working at liveboot session and airgeddon is also working perfectly.
airgeddon is only using bash scripts to change an adapter to monitor mode etc, so if you can do this manually from a terminal yourself, it would suggest the most likely issue is that your wifi adapter is being given a different name from the default that airgeddon is expecting.
You say that monitor mode is working from a live session, I’m assuming you mean Parrot booted from a USB drive, is the wifi adapter the computers built in one or external?
