+WDS is a non-standard mode which will be working between two Broadcom devices for instance
+but not between a Broadcom and Atheros device.
+
+\subparagraph{Unencrypted WDS connections}
+
+This configuration example shows you how to setup unencrypted WDS connections.
+We assume that the peer configured as below as the BSSID ca:fe:ba:be:00:01
+and the remote WDS endpoint ca:fe:ba:be:00:02 (option bssid field).

+It is also possible to encrypt WDS connections. \texttt{psk}, \texttt{psk2} and
+\texttt{psk+psk2} modes are supported. Configuration below is an example
+configuration using Pre-Shared-Keys with AES algorithm.

 you might be interested in adding support for another driver like Ralink RT2x00,
