RUN(4) Device Drivers Manual RUN(4)
NAME
run - Ralink Technology 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 and RT3000U 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.
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 (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 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 ifconfig.if(5).
FILES
The driver needs the following firmware files, which are loaded when an
interface is brought up:
/libdata/firmware/run/run-rt2870
/libdata/firmware/run/run-rt3071

EXAMPLES
The following ifconfig.if(5) example configures run0 to join whatever
network is available on boot, using WEP key "0x1deadbeef1", channel 11,
obtaining an IP address using DHCP:
dhcp NONE NONE NONE nwkey 0x1deadbeef1 chan 11
Join an existing BSS network, "my_net":
# ifconfig run0 192.168.1.1 netmask 0xffffff00 nwid my_net
DIAGNOSTICS
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.
run%d: could not load 8051 microcode An error occurred while attempting
to upload the microcode to the onboard 8051 microcontroller unit.
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.

HISTORY
The run driver first appeared in OpenBSD 4.5 and in NetBSD 7.0.
AUTHORS
The run driver was written by Damien Bergamini <damien@openbsd.org> for
OpenBSD and ported to NetBSD by FUKAUMI Naoki.
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.
