EXAMPLES

     ifconfig.if(5) example configures urtw0 to join whatever network is available on boot, using WEP key ``0x1deadbeef1'', channel 11, obtaining
     an IP address using DHCP:

	   nwkey 0x1deadbeef1 chan 11
	   dhcp

     Configure urtw0 to join network ``my_net'' using WPA with passphrase ``my_passphrase'':

	   # ifconfig urtw0 nwid my_net wpakey my_passphrase

     Join an existing BSS network, ``my_net'':

	   # ifconfig urtw0 192.168.1.1 netmask 0xffffff00 nwid my_net
