Each wireless driver has its own configuration script in \texttt{/lib/wifi/driver\_name.sh} which handles
driver specific options and configurations. This script is also calling driver specific binaries like wlc for
-Broadcom, or hostapd and wpa\_supplicant for atheros.
+Broadcom, or hostapd and wpa\_supplicant for atheros and mac80211.
The reason for using such architecture, is that it abstracts the driver configuration.

\item \texttt{maxassoc} \\
- Optional: Maximum number of associated clients. This feature is supported only on the broadcom chipset.

\item \texttt{distance} \\
- Optional: Distance between the ap and the furthest client in meters. This feature is supported only on the atheros chipset.
+ Optional: Distance between the ap and the furthest client in meters. This feature is supported only on the Atheros chipsets.
\item \texttt{mode} \\
- The frequency band (\texttt{b}, \texttt{g}, \texttt{bg}, \texttt{a}). This feature is only supported on the atheros chipset.

\item \texttt{rxantenna} \\
- Optional: Antenna identifier (0, 1 or 2) for reception. This feature is supported by atheros and some broadcom chipsets.

\item \texttt{txpower}
Set the transmission power to be used. The amount is specified in dBm.
\item \texttt{monitor} \\
Monitor mode
+ \item \texttt{mesh} \\
+ Mesh Point mode (802.11s)

\end{itemize}
+\paragraph{Mesh Point}
+
+Mesh Point (802.11s) is only supported by some mac80211 drivers. It requires the iw package
+to be installed to setup mesh links. OpenWrt creates mshN mesh point interfaces. A sample
+configuration looks like this:
+
+\begin{Verbatim}
+config wifi-device "wlan0"
+ option type "mac80211"
+ option channel "5"

+ option mesh_id "OpenWrt"
+\end{Verbatim}

\paragraph{Wireless Distribution System}
WDS is a non-standard mode which will be working between two Broadcom devices for instance
OpenWrt supports both 802.1x client and Access Point
configurations. 802.1x client is only working with
-Atheros or mac80211 drivers. Configuration only
-supports EAP types TLS, TTLS or PEAP.
