I'm trying to crack an wifi, but when i type
sudo airmon-ng start wlan0 it shows this:
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! 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)
Then, when I type
sudo airodump-ng mon0 for the list with available BSSID it shows this:
sudo airodump-ng mon0 Interface mon0: ioctl(SIOCGIFINDEX) failed: No such device
What can cause this?
This is my
wlan0 IEEE 802.11abg ESSID:off/any Mode:Managed Access Point: Not-Associated Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off ppp0 no wireless extensions. lo no wireless extensions.
My OS is 14.10. My Laptop is Aspire 5745G.
