<p>The Netgear box has its yellow ethernet cable socket set to the address <samp>10.0.1.1</samp>. The four other ethernet sockets are all on the address range <samp>192.168.200.x</samp> and the wifi network interface is set to <samp>192.168.200.1</samp> also in the network <samp>192.168.200.x</samp>.
<p>So the ethernet cable between the Netgear box and the netbook is <samp>10.0.1.1</samp> at the Netgear end and <samp>10.0.1.2</samp> at the netbook end. Nothing else uses any number like <samp>10.0.1.x</samp>.
<p>The line
<pre><code>sudo ip addr del 10.0.1.1/24 dev wlan0</code></pre>

[This happens if the netbook has lost its routing config (which is set up by runfakenet) and so there is no communication between the netbook and the router.]

<p>You may also need to re-enable wicd, see below.
<p>If it keeps failing, then maybe the <var>cron</var> system which re-triggers it every 60s is not working. That is probably a symptom of something more much more serious wrong with the netbook if you have already re-booted it. Try re-booting it again and this time be more patient. <em>Report this</em> to a nerd, <em>write a record of the problem in the expo logbook</em> and <em><a href="https://app.element.io/#/room/#LoserExpoWebsite:matrix.org">post a request for help</a></em> to the expo Matrix chat system.
