RUN(4)

NAME
run - Ralink Technology USB IEEE 802.11a/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 hostname.if(5).

FILES
The driver needs the following firmware files, which are loaded when an interface is brought up:

/etc/firmware/run-rt2870
/etc/firmware/run-rt3071

EXAMPLES
The following hostname.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

Configure run0 to join network “my_net” using WPA with passphrase “my_passphrase”:

    # ifconfig run0 nwid my_net wpakey my_passphrase

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.

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. Additional work is required in ieee80211(9) before those features can be supported.
