.Sh NAME

.Nm run
|
|
.Nd Ralink Technology USB IEEE 802.11a/b/g/n wireless network device
|
|
.Sh SYNOPSIS
|
|
.Cd "run* at uhub? port ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports USB 2.0 wireless adapters based on the Ralink RT2700U,
|
|
RT2800U and RT3000U 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), RT3022 (2T2R) or RT3052 (dual-band 2T2R)
|
|
radio transceiver.
|
|
.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 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
|
|
or on boot with
|
|
.Xr ifconfig.if 5 .
|
|
.Sh FILES
|
|
The driver needs the following firmware files,
|
|
which are loaded when an interface is brought up:
|
|
.Pp
|
|
.Bl -tag -width Ds -offset indent -compact
|
|

.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "run%d: error %d, could not read firmware %s"
|
|
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.

The

|
The
|
|
.Nm
|
|
driver was written by
|
|
.An Damien Bergamini
|
|
.Aq damien@openbsd.org
|
|
for
|
|
.Ox
|
|
and ported to

|
|
by
|
|
.An FUKAUMI Naoki .
|
|
.Sh CAVEATS
|
|
The
|
|
.Nm
|
|
driver does not support any of the 802.11n capabilities offered by the
|
|
RT2800 and RT3000 chipsets.
|
|
Additional work is required in
|
|
.Xr ieee80211 9
|
|
before those features can be supported.
