when I try to set up card to monitor mode: Ubuntu 18: wlan1: TL-WN722N wlan1 is not blocked by software...

on my kali linux all works fine!

>>>self._iwface
Card(phy=0,dev=wlan0,ifindex=3)
>>> newcard = pyw.devset(self._iwface, f'{self._iwface.dev}mon')
this line raise error:

newcard = pyw.devset(self._iwface, f'{self._iwface.dev}mon')
