+The WiFi settings are configured in the file \texttt{/etc/config/wireless}
+(currently supported on Broadcom only). When booting the router for the first time
+it should detect your card and create a sample configuration that looks like this:
+
+\begin{Verbatim}
+config wifi-device  wl0
+    option type     broadcom
+    option channel  5
+
+config wifi-iface
+    option device   wl0
+    option mode     ap
+    option ssid     OpenWrt
+    option hidden   0
+    option encryption none
+\end{Verbatim}
+
+There are two types of config sections in this file. The '\texttt{wifi-device}' refers to
+the physical wifi interface and '\texttt{wifi-iface}' configures a virtual interface on top
+of that (if supported by the driver).
+
+\paragraph{Options for the \texttt{wifi-device}:}
+
+\begin{itemize}
+	\item \texttt{type} \\
+		The driver to use for this interface.
+	
+	\item \texttt{country} \\
+		The country code used to determine the regulatory settings.
+	
+	\item \texttt{channel} \\
+		The wifi channel (1-14, depending on your country setting).
+
+	\item \texttt{maxassoc} \\
+		Maximum number of associated clients
+
+\end{itemize}
+
+\paragraph{Options for the \texttt{wifi-iface}:}
+
+\begin{itemize}
+	\item \texttt{mode} \\
+		Operating mode:
+		
+		\begin{itemize}
+			\item \texttt{ap} \\
+				Access point mode
+
+			\item \texttt{sta} \\
+				Client mode
+
+			\item \texttt{adhoc} \\
+				Ad-Hoc mode
+
+			\item \texttt{wds} \\
+				WDS point-to-point link
+				
+		\end{itemize}
+	\item \texttt{network} \\
+		Selects the interface section from \texttt{/etc/config/network} to be
+		used with this interface
+
+	\item \texttt{encryption} \\
+		Encryption setting. Accepts the following values:
+		
+		\begin{itemize}
+			\item \texttt{psk}, \texttt{psk2} \\
+				WPA(2) Pre-shared Key
+				
+			\item \texttt{wpa}, \texttt{wpa2} \\
+				WPA(2) RADIUS
+				
+		\end{itemize}
+		
+	\item \texttt{key} (wpa and psk) \\
+		Either the WPA key (PSK mode) or the RADIUS shared secret (WPA RADIUS mode)
+
+	\item \texttt{server} (wpa) \\
+		The RADIUS server address
+
+	\item \texttt{port} (wpa) \\
+		The RADIUS server port
+
+\end{itemize}
+
+\paragraph{Limitations:}
+
+\begin{itemize}
+	\item \textbf{Broadcom}: \\
+		Only the following mode combinations are supported:
+		
+		\begin{itemize}
+			\item 1x \texttt{sta}, 0-3x \texttt{ap}
+			\item 1-4x \texttt{ap}
+			\item 1x \texttt{adhoc}
+		\end{itemize}
+
+		WDS links can only be used in pure AP mode and can't use WEP (except when sharing the
+		settings with the master interface, which is done automatically).
+
+\end{itemize}
