EXAMPLES

Join an existing BSS network (i.e., connect to an access point):

ifconfig wlan0 create wlandev wpi0 inet 192.168.0.20 \
    netmask 0xffffff00

Join a specific BSS network with network name ``my_net ''

"ifconfig wlan0 create wlandev wpi0 ssid my_net up"

Join a specific BSS network with 64-bit WEP encryption:

ifconfig wlan0 create wlandev wpi0 ssid my_net \
        wepmode on wepkey 0x1234567890 weptxkey 1 up

Join a specific BSS network with 128-bit WEP encryption:

ifconfig wlan0 create wlandev wpi0 wlanmode adhoc ssid my_net \
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
