.Sh NAME
.Nm ral
.Nd "Ralink Technology RT2500 IEEE 802.11 driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ral"
.Cd "device wlan"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_ral_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports PCI/CardBus wireless adapters based on the Ralink RT2500
chipset.
.Pp
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).
.Pp
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).
.Pp
The transmit speed is user-selectable or can be adapted automatically by the
driver depending on the received-signal strength and the number of transmission
retries.
.Sh HARDWARE
The
.Nm
driver supports the following adapters:

.Sh HISTORY
The

driver first appeared in
.Ox 3.7 .
.Sh CAVEATS
PCI
.Nm
adapters seem to require a PCI 2.2 compliant motherboard and will likely not
work with PCI 2.1 only motherboard.
