#Detaching the ethernet cable for a while the LAN doesn't go up automatically when plugged again

##Solution

In **/etc/network/interfaces** change the line:

<pre class="minicom">
auto eth0
</pre>

in:

<pre class="minicom">
allow-hotplug eth0
</pre>

Then test the configuration by typing:

<pre class="minicom">
ifdown eth0
ifup eth0
</pre>
