Negative fixed channel

Hi,
For capturing handshake, after running command airodump-ng -c 52 --bssid DC:9F:DB:30:C1:7A -w . mon0
I see "fixed channel mon0: -1" on the top right corner.

is only displayed (momentarily) if I reconnect to wifi with same machine where I am running this aiodump.
From the Aircrack-ng website:
If you are having issues injecting or if you are receiving an error message talking about channel -1 or fixed channel in airodump-ng (top right of the screen) or aireplay-ng, kill the network managers using "airmon-ng check kill" before putting the wireless card in monitor mode.
I would recommend running airmon-ng check
first to see if it lists any processes that may need to be killed. If so, follow that with airmon-ng check kill
. If that doesn't work, I've also had luck putting my device into monitor mode manually with:
sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode monitor
sudo ifconfig wlan0 up
This method puts the device into monitor mode without creating a new mon0
virtual device, so be sure to use wlan0
where you would otherwise use mon0
for all of the tasks in the tutorial.
airmon-ng check kill
worked like a charm. Thanks.
I have the same issue but none of solutions worked for me
I used airmon-ng check kill before putting wlan in monitor mode but the problem still remain.
and solution2 give me this error :
~# sudo iwconfig wlan0 mode monitor
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Operation not supported.
any idea?
It looks like your device may not support monitor mode. I'd recommend purchasing a compatible USB WiFi dongle from this list.
