NAME
     ural -- Ralink Technology RT2500USB IEEE 802.11 driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device ehci
	   device uhci
	   device ohci
	   device usb
	   device ural
	   device wlan
	   device wlan_amrr

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_ural_load="YES"

DESCRIPTION
     The  ural	driver supports USB 2.0 wireless adapters based on the RT2500USB
     chipset.

     The RT2500USB chipset consists of two integrated chips,  a  RT2570  MAC/BBP
     and a radio transceiver (the model of which depends on the card revision).

     The  RT2522,  RT2523, RT2524, RT2525, RT2525e and RT2526 radio transceivers
     operate in the 2.4GHz band (802.11b/g) whereas the RT5222	is  a  dual-band
     radio  transceiver  that  can  operate  in  the  2.4GHz  and  5.2GHz  bands
     (802.11a).

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

	   ifconfig ural0 inet 192.168.0.20 netmask 0xffffff00

     Join a specific BSS network with network name "my_net":

	   ifconfig ural0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

	   ifconfig ural0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x1234567890 weptxkey 1

     Join a specific BSS network with 104-bit WEP encryption:

	   ifconfig ural0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
