Never thought this XKCD out of all of them would become relevant at some point... https://xkcd.com/416/ https://xkcd.com/416/

  I know someone who wrote code to find all wifi networks where the password was trivially finable from the mac address (used to be common with ISP routers). Then connect to those. Then they extended it to DoS any network like that where the user had changed the ssid or password. Usually the user would reset the router back to the defaults, and they could connect. Or they'd accidentally hit the WPS button while trying to reset it, and again connection was easy. By using SoftMac mode a wifi adapter could do that attack to ~50 local networks in parallel, and usually get a solid connection after just a few minutes.
