fix for -1 channel

first run this-   iw reg set JP     (run that command at everystart up of your pc or wireless card)

command this-   iw dev wlan0 interface add mon0 type monitor

(sadly you must run the command above everytime you restart your pc or unplug your wireless card)



important do this exactly-

(this will disable wlan0 so mon0 will not have any interference) the command is-   ifconfig wlan0 down    (or wlan1 if thats the name of your wireless card)
then run this-   ifconfig mon0 up
Type: ifconfig [interface of wireless card] down and hit Enter.
Replace [interface of wireless card] with the name of the interface that you enabled mon0 on; probably called wlan0. This disables the wireless card from connecting to the internet, allowing it to focus on monitor mode instead.
