Well I shouldn't need to state this but depending on where you live be sure there arn't any laws against jamming your WiFi or anyone elses WiFi before starting this project.
Also note this isn't my own project just a video I made on me preforming and installing the firmware and following the tutorial that the user " https://github.com/spacehuhn " made on github.
Ps: Stick around and in a future video I will be using this to capture a handshake.
