.Sh NAME
.Nm run
.Nd Ralink Technology USB IEEE 802.11a/g/n wireless network device
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ehci"
.Cd "device uhci"
.Cd "device ohci"
.Cd "device usb"
.Cd "device run"
.Cd "device wlan"
.Cd "device wlan_amrr"
.Ed
.Pp
Firmware is also needed, and provided by:
.Bd -ragged -offset indent
.Cd "device runfw"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following lines in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_run_load="YES"
runfw_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports USB 2.0 wireless adapters based on the Ralink RT2700U,
RT2800U, RT3000U and RT3900E chipsets.
.Pp
The RT2700U chipset consists of two integrated chips, an RT2770 MAC/BBP and
an RT2720 (1T2R) or RT2750 (dual-band 1T2R) radio transceiver.
.Pp
The RT2800U chipset consists of two integrated chips, an RT2870 MAC/BBP and
an RT2820 (2T3R) or RT2850 (dual-band 2T3R) radio transceiver.
.Pp
The RT3000U is a single-chip solution based on an RT3070 MAC/BBP and
an RT3020 (1T1R), RT3021 (1T2R) or RT3022 (2T2R) single-band radio
transceiver.
.Pp
The RT3900E is a single-chip USB 2.0 802.11n solution.
The MAC/Baseband Processor can be an RT3593, RT5390, RT5392 or an RT5592.
The radio can be an RT3053, RT5370, RT5372 or an RT5572.
The RT3053 chip operates in the 2GHz and 5GHz spectra and supports up to
3 transmit paths and 3 receiver paths (3T3R).
The RT5370 chip operates in the 2GHz spectrum and supports 1 transmit path
and 1 receiver path (1T1R).
The RT5372 chip operates in the 2GHz spectrum and supports up to 2 transmit
paths and 2 receiver paths (2T2R).
The RT5572 chip operates in the 2GHz and 5GHz spectra and supports up to
2 transmit paths and 2 receiver paths (2T2R).
.Pp
These are the modes the
.Nm
driver can operate in:
.Bl -tag -width "IBSS-masterXX"
.It BSS mode
Also known as
.Em infrastructure
mode, this is used when associating with an access point, through
which all traffic passes.
This mode is the default.
.It Host AP mode
In this mode the driver acts as an access point (base station)
for other cards.
.It monitor mode
In this mode the driver is able to receive packets without
associating with an access point.
This disables the internal receive filter and enables the card to
capture packets from networks which it wouldn't normally have access to,
or to scan for access points.
.El
.Pp
The
.Nm
driver can be configured to use
Wired Equivalent Privacy (WEP) or
Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).
WPA is the de facto encryption standard for wireless networks.
It is strongly recommended that WEP
not be used as the sole mechanism
to secure wireless communication,
due to serious weaknesses in it.
The
.Nm
driver offloads both encryption and decryption of data frames to the
hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP ciphers.
.Pp
The
.Nm
driver can be configured at runtime with
.Xr ifconfig 8 .
.Sh HARDWARE

.Nm
driver supports the following wireless adapters:

.Sh DIAGNOSTICS
.Bl -diag
.It "run%d: failed load firmware of file runfw"
For some reason, the driver was unable to read the microcode file from the
filesystem.
The file might be missing or corrupted.
.It "run%d: could not load 8051 microcode"
An error occurred while attempting to upload the microcode to the onboard 8051
microcontroller unit.
.It "run%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.
