RAL(4)                 FreeBSD Kernel Interfaces Manual                 RAL(4)

NAME
     ral - Ralink Technology IEEE 802.11 wireless network driver

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

           device ral
           device ralfw
           device wlan
           device wlan_amrr
           device firmware

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

           if_ral_load="YES"

DESCRIPTION
     The ral driver supports PCI/CardBus wireless adapters based on the Ralink
     Technology RT2500, RT2501, and RT2600 chipsets.

     The RT2500 chipset is the first generation of 802.11b/g adapters from
     Ralink.  It consists of two integrated chips, a RT2560 MAC/BBP and a
     RT2525 radio transceiver.

     The RT2501 chipset is the second generation of 802.11b/g adapters from
     Ralink.  It consists of two integrated chips, a RT2561 MAC/BBP and a
     RT2527 radio transceiver.  This chipset provides support for the IEEE
     802.11e standard with multiple hardware transmission queues and allows
     scatter/gather for efficient DMA operations.

     The RT2600 chipset consists of two integrated chips, a RT2661 MAC/BBP and
     a RT2529 radio transceiver.  This chipset uses the MIMO (multiple-input
     multiple-output) technology with multiple antennas to extend the
     operating range of the adapter and to achieve higher throughput.  MIMO is
     the basis of the forthcoming IEEE 802.11n standard.

     The transmit speed is user-selectable or can be adapted automatically by
     the driver depending on the received signal strength and on the number of
     hardware transmission retries.

     ral supports station, adhoc, hostap, mesh, wds, and monitor mode
     operation.  Only one hostap or mesh virtual interface may be configured
     at a time.  Any number of wds virtual interfaces may be configured
     together with a hostap interface.  Multiple station interfaces may be
     operated together with a hostap interface to construct a wireless
     repeater device.  For more information on configuring this device, see
     ifconfig(8).

HARDWARE

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

           ifconfig wlan create wlandev ral0 inet 192.168.0.20 netmask
           0xffffff00

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

           ifconfig wlan create wlandev ral0 inet 192.168.0.20 \
               netmask 0xffffff00 ssid my_net

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

           ifconfig wlan create wlandev ral0 inet 192.168.0.20 \
               netmask 0xffffff00 ssid my_net \

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

           ifconfig wlan create wlandev ral0 inet 192.168.0.20 \
               netmask 0xffffff00 ssid my_net \

DIAGNOSTICS
     ral%d: could not load 8051 microcode  An error occurred while attempting
     to upload the microcode to the onboard 8051 microcontroller unit.

     ral%d: timeout waiting for MCU to initialize  The onboard 8051
     microcontroller unit failed to initialize in time.

     ral%d: device timeout  A frame dispatched to the hardware for
     transmission did not complete in time.  The driver will reset the
     hardware.  This should not happen.

HISTORY
     The ral driver first appeared in OpenBSD 3.7.

AUTHORS
     The original ral driver was written by Damien Bergamini
     <damien@FreeBSD.org>.

BUGS
     Host AP mode doesn't support client power save.  Clients using power save
     mode will experience packet loss (disabling power saving on the client
     will fix this).
