 Troubleshooting
 ---------------
 
+How do I know what profile has been chosen by guessnet?
+-------------------------------------------------------
+
+You have three options:
+
+ 1. see the current ifupdown mapping: ``cat /etc/network/ifstate``
+ 2. activate debug output by adding ``map debug: true`` to the ``mapping``
+    section of ``/etc/network/interfaces``
+ 3. run a guessnet scan directly: ``cat /dev/null | guessnet -i eth0``.
+
+
+Why is guessnet working in commandline but not in ifupdown?
+-----------------------------------------------------------
+
+One common cause for this is a network driver which takes some time to bring up
+the interface, so guessnet works fine when invoked on the commandline with the
+interface already up, but when run in ifupdown to bring up the interface,
+guessnet times out before the driver has finished with the initialization.
+
+If that is the case, just increase the timeout: add ``map timeout: 10`` in the
+``mapping`` stanza of ``/etc/network/interfaces`` and see if it gets better.
+If it does, try decreasing the timeout to get the optimal value for you.
+
+
 Link beat does not work: when guessnet tries to check it, the interface is still down for configuration
