URAL(4)		       FreeBSD Kernel Interfaces Manual		       URAL(4)

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 revi-
     sion).

     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).

HARDWARE
     The ural driver supports USB 2.0 wireless adapters	based on the Ralink
     Technology	RT2500USB chipset, including:

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

     Join a specific BSS network with 40-bit WEP encryption:

	   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
