title: How can I control access to a Wifi Router using Python-Flask?
body: <p>I would like to write a mini web-app to control clients' internet access on a Wifi-router.</p>
  
  <p>How can I block/regulate their Internet usage while connected to the router?</p>
  
  <p>Each client would have a login username &amp; password. I do not want to use a <em>MAC-address filter</em> as they could login using any device.</p>
