RUN(4)                  NetBSD Kernel Interfaces 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 asso-
                    ciating 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 communica-
     tion, 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 transmis-
     sion 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.
