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 HARDWARE The following adapters should work: Airlink101 AWLL6090 ASUS USB-N11 ASUS USB-N13 ASUS WL-160N Belkin F5D8051 ver 3000 Belkin F5D8053 Belkin F5D8055 Belkin F6D4050 ver 1 Belkin F6D4050 ver 2 Belkin F7D1101 ver 2 Buffalo WLI-UC-AG300N Buffalo WLI-UC-G300N Buffalo WLI-UC-G301N Buffalo WLI-UC-GN Buffalo WLI-UC-GNHP Buffalo WLI-UC-GNM Buffalo WLI-UC-GNM2 Cisco AM10 Corega CG-WLUSB2GNL Corega CG-WLUSB2GNR Corega CG-WLUSB300AGN Corega CG-WLUSB300GNM D-Link DWA-130 rev B1 D-Link DWA-140 DrayTek Vigor N61 Edimax EW-7711UAn Edimax EW-7711UTn Edimax EW-7717Un Edimax EW-7718Un Edimax EW-7722UTn Gigabyte GN-WB30N Gigabyte GN-WB31N Gigabyte GN-WB32L Hawking HWDN1 Hawking HWUN1 Hawking HWUN2 Hercules HWNU-300 Linksys AE1000 Linksys WUSB54GC v3 Linksys WUSB600N Logitec LAN-W150N/U2 Logitec LAN-W300N/U2 Mvix Nubbin MS-811N Planex GW-US300Mini-X Planex GW-US300MiniS Planex GW-US300MiniW Planex GW-USMicro300 Planex GW-USMicroN Sitecom WL-182 Sitecom WL-188 Sitecom WL-301 Sitecom WL-302 Sitecom WL-315 Sitecom WLA-4000 Sitecom WLA-5000 SMC SMCWUSBS-N2 Sweex LW153 Sweex LW303 Sweex LW313 TRENDnet TEW-645UB Unex DNUR-81 Unex DNUR-82 ZyXEL NWD-211AN ZyXEL NWD-271N ZyXEL NWD2105 ZyXEL NWD210N ZyXEL NWD2205 ZyXEL NWD270N 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.

AUTHORS The run driver was written by Damien Bergamini <email@example.com> 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.
