|
|
.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"
|
|
.Cd "device wlan_amrr"
|
|
.Cd "device firmware"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports PCI/PCIe/CardBus wireless adapters based on the Ralink RT2500,
|
|
RT2501, RT2600, RT2700, RT2800, RT3090 and RT3900E chipsets.
|
|
.Pp
|
|
The RT2500 chipset is the first generation of 802.11b/g adapters from Ralink.
|
|
It consists of two integrated chips, an RT2560 MAC/BBP and an RT2525 radio
|
|
transceiver.
|
|
.Pp
|
|
The RT2501 chipset is the second generation of 802.11a/b/g adapters from
|
|
Ralink.
|
|
It consists of two integrated chips, an RT2561 MAC/BBP and an 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.
|
|
.Pp
|
|
The RT2600 chipset consists of two integrated chips, an RT2661 MAC/BBP and an
|
|
RT2529 radio transceiver.
|
|
This chipset uses the MIMO (multiple-input multiple-output) technology with
|
|
multiple radio transceivers to extend the operating range of the adapter and
|
|
to achieve higher throughput.
|
|
However, the RT2600 chipset does not support any of the 802.11n features.
|
|
.Pp
|
|
The RT2700 chipset is a low-cost version of the RT2800 chipset.
|
|
It supports a single transmit path and two receiver paths (1T2R).
|
|
It consists of two integrated chips, an RT2760 or RT2790 (PCIe) MAC/BBP and
|
|
an RT2720 (2.4GHz) or RT2750 (2.4GHz/5GHz) radio transceiver.
|
|
.Pp
|
|
The RT2800 chipset is the first generation of 802.11n adapters from Ralink.
|
|
It consists of two integrated chips, an RT2860 or RT2890 (PCIe) MAC/BBP and
|
|
an RT2820 (2.4GHz) or RT2850 (2.4GHz/5GHz) radio transceiver.
|
|
The RT2800 chipset supports two transmit paths and up to three receiver
|
|
paths (2T2R/2T3R).
|
|
It can achieve speeds up to 144Mbps (20MHz bandwidth) and 300Mbps (40MHz
|
|
bandwidth.)
|
|
.Pp
|
|
The RT3090 chipset is the first generation of single-chip 802.11n adapters
|
|
from Ralink.
|
|
.Nm
|
|
supports
|
|
.Cm station ,
|
|
.Cm adhoc ,
|
|
.Cm hostap ,
|
|
.Cm mesh ,
|
|
.Cm wds ,
|
|
and
|
|
.Cm monitor
|
|
mode operation.
|
|
Only one
|
|
.Cm hostap
|
|
or
|
|
.Cm mesh
|
|
virtual interface may be configured at a time.
|
|
Any number of
|
|
.Cm wds
|
|
virtual interfaces may be configured together with a
|
|
.Cm hostap
|
|
interface.
|
|
Multiple
|
|
.Cm station
|
|
interfaces may be operated together with a
|
|
.Cm hostap
|
|
interface to construct a wireless repeater device.
|
|
.Pp
|
|
The RT3900E chipset is a single-chip 802.11n adapters from Ralink.
|
|
The MAC/Baseband Processor can be an RT5390 or RT5392.
|
|
The RT5390 chip operates in the 2GHz spectrum and supports 1 transmit path
|
|
and 1 receiver path (1T1R).
|
|
The RT5392 chip operates in the 2GHz spectrum and supports up to 2 transmit
|
|
paths and 2 receiver paths (2T2R).
|
|
.Pp
|
|
The transmit speed is user-selectable or can be adapted automatically by the
|
|
driver depending on the number of hardware transmission retries.
|
|

.Sh CAVEATS
|
|
The
|
|
.Nm
|
|
driver does not make use of the hardware cryptographic engine.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver does not support any of the 802.11n capabilities offered by
|
|
the RT2700 and RT2800 chipsets.
|
|
Additional work is required in before those features can be supported.
|
|
.Pp
|
|
Host AP mode does not support power saving.
|
|
Clients attempting to use power saving mode may experience significant
|
|
packet loss (disabling power saving on the client will fix this).
|
|
.Pp
|
|
Some PCI
|
|
.Nm
|
|
adapters strictly require a system supporting PCI 2.2 or greater.
|
|
Check the board's PCI version before purchasing the card as it is likely these
|
|
adapters will not work in systems based on older revisions of the PCI
|
|
specification.
