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

     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).

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

     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
