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 wconfig
:
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.
