This mode is the default. .It 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. .El .Pp The .Nm 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 .Nm driver offloads both encryption and decryption of data frames to the hardware for the WEP40, WEP104, TKIP(+MIC) and CCMP ciphers. .Pp The .Nm driver can be configured at runtime with .Xr ifconfig 8 or on boot with .Xr hostname.if 5 . .Sh FILES The driver needs the following firmware files, which are loaded when an interface is brought up: .Pp .Bl -tag -width Ds -offset indent -compact .It /etc/firmware/run-rt2870 .It /etc/firmware/run-rt3071 .El .Sh HARDWARE The following adapters should work: .Pp .Bl -tag -width Ds -offset indent -compact .It Airlink101 AWLL6090 .It ASUS USB-N11 .It ASUS USB-N13 .It ASUS USB-N53 .It ASUS WL-160N .It Belkin F5D8051 ver 3000 .It Belkin F5D8053 .It Belkin F5D8055 .It Belkin F6D4050 ver 1 .It Belkin F6D4050 ver 2 .It Belkin F7D1101 ver 2 .It Buffalo WLI-UC-AG300N .It Buffalo WLI-UC-G300N .It Buffalo WLI-UC-G301N .It Buffalo WLI-UC-GN .It Buffalo WLI-UC-GNHP .It Buffalo WLI-UC-GNM .It Buffalo WLI-UC-GNM2 .It Cisco AM10 .It Corega CG-WLUSB2GNL .It Corega CG-WLUSB2GNR .It Corega CG-WLUSB300AGN .It Corega CG-WLUSB300GNM .It D-Link DWA-127 .It D-Link DWA-130 rev B1 .It D-Link DWA-140 .It DrayTek Vigor N61 .It Edimax EW-7711UAn .It Edimax EW-7711USn .It Edimax EW-7711UTn .It Edimax EW-7717Un .It Edimax EW-7718Un .It Edimax EW-7722UTn .It Gigabyte GN-WB30N .It Gigabyte GN-WB31N .It Gigabyte GN-WB32L .It Hawking HWDN1 .It Hawking HWUN1 .It Hawking HWUN2 .It Hercules HWNU-300 .It Keebox W150NU .It Linksys AE1000 .It Linksys WUSB54GC v3 .It Linksys WUSB600N .It Logitec gLAN-W150NU2BK .It Logitec LAN-W150N/U2 .It Logitec LAN-W300N/U2 .It Logitec LAN-W300N/U2S .It Mvix Nubbin MS-811N .It Planex GW-USMicroN .It Planex GW-US300MiniS .It Sitecom WL-182 .It Sitecom WL-188 .It Sitecom WL-301 .It Sitecom WL-302 .It Sitecom WL-315 .It Sitecom WLA-4000 .It Sitecom WLA-5000 .It SMC SMCWUSBS-N2 .It Sweex LW153 .It Sweex LW303 .It Sweex LW313 .It TRENDnet TEW-645UB .It Unex DNUR-81 .It Unex DNUR-82 .It ZyXEL NWD-211AN .It ZyXEL NWD-271N .It ZyXEL NWD2105 .It ZyXEL NWD210N .It ZyXEL NWD2205 .It ZyXEL NWD270N .El .Sh EXAMPLES The following example scans for available networks: .Pp .Dl # ifconfig run0 scan .Pp The following .Xr hostname.if 5 example configures run0 to join network .Dq mynwid , using WPA key .Dq mywpakey , obtaining an IP address using DHCP: .Bd -literal -offset indent nwid mynwid wpakey mywpakey dhcp .Ed .Sh DIAGNOSTICS .Bl -diag .It "run0: error N, could not read firmware ..." For some reason, the driver was unable to read the microcode file from the filesystem. The file might be missing or corrupted. .It "run0: could not load 8051 microcode" An error occurred while attempting to upload the microcode to the onboard 8051 microcontroller unit. .It "run0: 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. .El .Sh SEE ALSO .Xr arp 4 , .Xr ifmedia 4 , .Xr intro 4 , .Xr netintro 4 , .Xr usb 4 , .Xr hostname.if 5 , .Xr ifconfig 8 .Pp Ralink Technology: .Lk http://www.ralinktech.com/ .Sh HISTORY The .Nm driver first appeared in .Ox 4.5 . .Sh AUTHORS The .Nm driver was written by .An Damien Bergamini Aq Mt damien.bergamini@free.fr . .Sh CAVEATS The .Nm driver does not support any of the 802.11n capabilities offered by the RT2800 and RT3000 chipsets. Additional work is required in .Xr ieee80211 9 before those features can be supported.
