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

     ral -- Ralink Technology RT2500 IEEE 802.11 driver

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

           device ral
           device wlan

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


     The ral driver supports PCI/CardBus wireless adapters based on the Ralink
     RT2500 chipset.

     The RT2500 chipset consists of two integrated chips, a RT2560 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

     The transmit speed is user-selectable or can be adapted automatically by
     the driver depending on the received-signal strength.

     The ral driver supports the following adapters:

     Ralink Technology,

     The ral driver first appeared in OpenBSD 3.7.

     PCI ral adapters seem to require a PCI 2.2 compliant motherboard and will
     likely not work with PCI 2.1 only motherboard.

     The ral driver was written by Damien Bergamini <>.
