Answer by Mohammad Ali for "No wireless interfaces found"

As the documentation that can be found hereSays, the command:

Sudo airmon-ng check kill

Will “stop network managers then kill interfering processes left” which means that your raspberry pi’s ability to connect to wifi will be disabled. I would recommend you either reboot the whole system with the following command

Sudo reboot

Or restart the pis, network interface with the following command:

service networking restart
