   1 The WiFi settings are configured in the file \texttt{/etc/config/wireless}
   2 (currently supported on Broadcom only). When booting the router for the first time
   3 it should detect your card and create a sample configuration that looks like this:
   4
   5 \begin{Verbatim}
   6 config wifi-device  wl0
   7     option type     broadcom
   8     option channel  5
   9
  10 config wifi-iface
  11     option device   wl0
  12     option mode     ap
  13     option ssid     OpenWrt
  14     option hidden   0
  15     option encryption none
  16 \end{Verbatim}
  17
  18 There are two types of config sections in this file. The '\texttt{wifi-device}' refers to
  19 the physical wifi interface and '\texttt{wifi-iface}' configures a virtual interface on top
  20 of that (if supported by the driver).
  21
  22 \paragraph{Options for the \texttt{wifi-device}:}
  23
  24 \begin{itemize}

  32                 The wifi channel (1-14, depending on your country setting).

  85
  86 \paragraph{Limitations:}
  87
  88 \begin{itemize}
  89         \item \textbf{Broadcom}: \\
  90                 Only the following mode combinations are supported:
  91
  92                 \begin{itemize}
  93                         \item 1x \texttt{sta}, 0-3x \texttt{ap}
  94                         \item 1-4x \texttt{ap}
  95                         \item 1x \texttt{adhoc}
  96                 \end{itemize}
  97
  98                 WDS links can only be used in pure AP mode and can't use WEP (except when sharing the
  99                 settings with the master interface, which is done automatically).
