the “rabbit” access point and set a transmit rate of 11 Mbits/s, you would have these two
lines of code in your program.
Let’s look at the individual
WIFI_SSID
An SSID (service set identifier) names a specific wireless LAN (WLAN). All devices on a
single WLAN must share a common SSID. Set this value to your WLAN’s SSID. If you
leave the SSID blank, the Rabbit-based device will associate automatically with the access
point that has the strongest signal. Generally, it is best to set the SSID explicitly so that the
device does not join a WLAN that you were not expecting it to join.
For an infrastructure network (one that uses an access point), this is the name of the network
as configured on the access point.
For an ad-hoc network, this is the name that you want to give the network you created. All
devices on the ad-hoc network must use the same SSID.
WIFI_MULTI_DOMAIN
This command enables or disables your device to be configured by an access point that is
capable of supporting multiple domains according to the 802.11d standard. When your
device is enabled, the access point will provide country information to your device to
identify the regulatory domain in which it is located and to configure its PHY for opera-
tion in that regulatory domain.

int wifi_ioctl(IF_WIFI0, WIFI_SSID, "rabbit", 0);
int wifi_ioctl(IF_WIFI0, WIFI_TX_RATE, WIFICONF_RATE_11MBPS, 0);
NOTE: The access point must have the 802.11d option enabled with the country selected
according to where your wireless device is deployed.
