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 trans‐
     ceiver.

     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.

     Host AP mode   In this mode the driver acts as an access point (base sta‐
		    tion) 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 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).

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 transmis‐
     sion did not complete in time.  The driver will reset the hardware.  This
     should not happen.
