 + 
 +**Take down an interface** \\ \\  
 + 
 +''iplink set wl1.3 down'' \\

 +==== Specific WiFi SSID Operation ====
 +
 +Often, a specific defined SSID operates on multiple interfaces/sub-interfaces. You can disable that SSID on all interfaces everywhere, as follows:\\
  
  \\  \\
  
 +**Force Off** \\ \\ 
 +
 +''SSID=MYCOOLSSID''\\ \\ '' nvram show | grep ssid | grep $SSID | while read line; do wl -i $(echo $line | cut -d"=" -f1 | cut -d_ -f1 ) radio off; done''
