+ <h2>Interaction with wired interfaces</h2>
+ <p>
+ When you have an ethernet jack as well in your laptop you might be tempted to put this in your <tt>/etc/network/interfaces</tt> as well
+ <pre>
+auto enp0s31f6
+iface enp0s31f6 inet dhcp
+ </pre>
+ However, this results in your machine eagerly waiting for a connection at boot because a <em>connected</em> ethernet jack means a connected card, and the card is always connected in a laptop.
+ <tt>ifupdown-extra</tt> contains scripts to fix this.
+ Just link <tt>/etc/network/if-up.d/00check-network-cable</tt> to <tt>/etc/network/if-pre-up.d/00check-network-cable</tt> and be good to go.
+ If your system has <em>predictable</em> network names you might need to apply <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=970359">this</a> patch first
