RUN(4) FreeBSD Kernel Interfaces Manual RUN(4)
NAME
run - Ralink Technology/MediaTek USB IEEE 802.11a/b/g/n wireless network
device
SYNOPSIS
run* at uhub? port ?
DESCRIPTION
The run driver supports USB 2.0 wireless adapters based on the Ralink
RT2700U, RT2800U, RT3000U and RT3900E chipsets.
The RT2700U chipset consists of two integrated chips, an RT2770 MAC/BBP
and an RT2720 (1T2R) or RT2750 (dual-band 1T2R) radio transceiver.
The RT2800U chipset consists of two integrated chips, an RT2870 MAC/BBP
and an RT2820 (2T3R) or RT2850 (dual-band 2T3R) radio transceiver.
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.
The RT3900E is a single-chip solution based on an RT3593, RT5390, RT5392
or an RT5592 MAC/BBP and an RT3053 (dual-band 3T3R), RT5370 (1T1R),
RT5372 (2T2R), or RT5572 (dual-band 2T2R) radio transceiver.
These are the modes the run driver can operate in:
BSS mode Also known as infrastructure mode, this is used when
associating with an access point, through which all
traffic passes. This mode is the default.
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.
The run driver can be configured to use Wired Equivalent Privacy (WEP) or
Wi-Fi Protected Access (WPA1 and WPA2). WPA2 is currently the most
secure encryption standard for wireless networks supported by OpenBSD.
It is strongly recommended that neither WEP nor WPA1 are used as the sole
mechanism to secure wireless communication, due to serious weaknesses.
WPA1 is disabled by default and may be enabled using the option
"wpaprotos wpa1,wpa2". For standard WPA networks which use pre-shared
keys (PSK), keys are configured using the "wpakey" option. WPA-
Enterprise networks require use of the wpa_supplicant package. The run
driver offloads both encryption and decryption of data frames to the
hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP ciphers.
The run driver can be configured at runtime with ifconfig(8) or on boot
with hostname.if(5).
FILES
The driver needs the following firmware files, which are loaded when an
interface is brought up:

EXAMPLES
The following example scans for available networks:
# ifconfig run0 scan
The following hostname.if(5) example configures run0 to join network
"mynwid", using WPA key "mywpakey", obtaining an IP address using DHCP:
join mynwid wpakey mywpakey
inet autoconf
DIAGNOSTICS
run0: error N, could not read firmware ... For some reason, the driver
was unable to read the microcode file from the filesystem. The file
might be missing or corrupted.
run0: could not load 8051 microcode An error occurred while attempting
to upload the microcode to the onboard 8051 microcontroller unit.
run0: 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.

HISTORY
The run driver first appeared in OpenBSD 4.5.

CAVEATS
The run driver does not support any of the 802.11n capabilities offered
by the RT2800 and RT3000 chipsets. Additional work is required in
ieee80211(9) before those features can be supported.
