   The idea of using a Raspberry Pi would work!   
      
   It's actually probably perfect in that it's highly programmable, and it has   
   all the necessary WiFi, Ethernet, and USB connections!   
      
   I did try out the WatchDog feature of all Ubiquiti radios.   
   Here's my Rocket M5, for example, which has 28 dBm of transmit power into a   
   30 dBm dish which means I can pickup or throw my Internet for ten miles.   
      
      
   The Ping Watchdog facility was unused when I looked just now:   
      
      
   I turned the Ping Watchdog on, and set it to 86,400 seconds (1 day), and   
   then set the ping failure number to 7 days.   
      
      
   The question is what IP address to ping that doesn't exist on the net?   
   It wouldn't take 192.168.1.256   
      
      
   So I picked an IP address that doesn't exist on my net of 192.168.1.254   
      
      
   This only works if you have the login to the radio, which most people on   
   WISP do not have access to though. So the WISP admin has to set it up.
