+Put the interface in "monitor mode"; this is supported only on IEEE
+802.11 Wi-Fi interfaces, and supported only on some operating systems.
+
+Note that in monitor mode the adapter might disassociate from the
+network with which it's associated, so that you will not be able to use
+any wireless networks with that adapter.  This could prevent accessing
+files on a network server, or resolving host names or network addresses,
+if you are capturing in monitor mode and are not connected to another
+network with another adapter.
