.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:
