I have installed the latest version of aircrack-ng, but when i run this code, sudo airmon-ng start wlan0 I get this. sudo airmon-ng start wlan0 Found 4 processes that could cause trouble. If airodump-ng, aireplay-ng or airtun-ng stops working after a short period of time, you may want to kill (some of) them! -e PID Name 463 avahi-daemon 475 avahi-daemon 683 NetworkManager 756 wpa_supplicant Interface Chipset Driver wlan0 Broadcom wl - [phy0]mon0: ERROR while getting interface flags: No such device (monitor mode enabled on mon0) Is there anyone who could help me get this problem solved please.
