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{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} \\ |
||||||
|

||||||

\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) \\ |
||||||
|

||||||
|
|
||||||
|
\item \texttt{port} (wpa) \\ |
||||||

\end{itemize} |

\paragraph{Limitations:} |
||||||
|
|
||||||
|
\begin{itemize} |

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). |
||||||
|
|
||||||
|
