NAME

       run — Ralink Technology USB IEEE 802.11a/g/n wireless network device

SYNOPSIS

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             device ehci
             device uhci
             device ohci
             device usb
             device run
             device wlan
             device wlan_amrr

       Firmware is also needed, and provided by:

             device runfw

       Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):

             if_run_load="YES"
             runfw_load="YES"

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) or
RT3022 (2T2R) single-band 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.

Host AP mode In this mode the driver acts as an access point (base station) for other cards.

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).

EXAMPLES

       Join an existing BSS network (i.e., connect to an access point):

             ifconfig wlan create wlandev run0 inet 192.168.0.20 \
                 netmask 0xffffff00

       Join a specific BSS network with network name “my_net”:

             ifconfig wlan create wlandev run0 ssid my_net up

       Join a specific BSS network with 64-bit WEP encryption:

             ifconfig wlan create wlandev run0 ssid my_net \
                     wepmode on wepkey 0x1234567890 weptxkey 1 up

       Join a specific BSS network with 128-bit WEP encryption:

             ifconfig wlan create wlandev run0 wlanmode adhoc ssid my_net \
                 wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

       run%d:  faild  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.

       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.

AUTHORS

       The run driver was written by Damien Bergamini <damien@openbsd.org>.

CAVEATS

       The run driver does not support any of  the  802.11n  capabilities  offered  by  the  RT2800  and  RT3000
       chipsets.
