The WiFi settings are configured in the file \texttt{/etc/config/wireless}
|
|
(currently supported on Broadcom and Atheros). When booting the router for the first time
|
|
it should detect your card and create a sample configuration file. By default '\texttt{option network lan}' is
|
|
commented. This prevents unsecured sharing of the network over the wireless interface.

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{Limitations:}

|
|
|
\begin{itemize}
