WIFI_COUNTRY_GET
This command returns country-specific information into the user-supplied buffer (or data
structure) area. Accordingly, you must ensure there is enough space in the buffer for the
entire data structure. Be sure the data pointer points to a buffer that is large enough to hold
sizeof(_wifi_country)
The
WIFI_MODE
Sets whether the Wi-Fi device should attach to an infrastructure network (

(
communication among all the associated devices. No wireless access points are associated
with the ad-hoc mode. This allows devices (such as Rabbit-based devices and notebooks)
to communicate with each other directly as peer devices without an access point.
WIFI_OWNCHAN
This parameter specifies the channel the Wi-Fi device uses in your network when operat-
ing in the ad-hoc mode. Set this parameter to "0" in an infrastructure network to allow the
Wi-Fi driver to pick the channel automatically for the given SSID. For an ad-hoc network,
this channel must be set to "1" through "13". Use the
get the valid range of channels for the country where the device will be used.
WIFI_WEP_FLAG
The encryption flag can have one of three values—disabled (
WEP encryption enabled (
(
WEP (Wired Equivalent Privacy).
WIFI_WEP_USEKEY
Indicates which key ("0"–"3") is the default transmission key. The setting may be left at
the "0" default. The setting of the WEP keys is described below.
