RUM(4)		       FreeBSD Kernel Interfaces Manual			RUM(4)

NAME
     rum -- Ralink Technology USB IEEE 802.11a/b/g 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 rum
	   device wlan
	   device wlan_amrr

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_rum_load="YES"

DESCRIPTION
     The rum driver supports USB 2.0 and PCI Express Mini Card wireless
     adapters based on the Ralink RT2501USB and	RT2601USB chipsets.

     Ralink PCI	Express	Mini Card adapters show	up as normal USB 2.0 devices
     and are thus handled by the rum driver.

     The RT2501USB chipset is the second generation of 802.11a/b/g adapters
     from Ralink.  It consists of two integrated chips,	an RT2571W MAC/BBP and
     an	RT2528 or RT5226 radio transceiver.

     The RT2601USB chipset consists of two integrated chips, an	RT2671 MAC/BBP
     and an RT2527 or RT5225 radio transceiver.	 This chipset uses the MIMO
     (multiple-input multiple-output) technology with multiple antennas	to
     extend the	operating range	of the adapter and to achieve higher through-
     put.

HARDWARE
     The rum driver supports USB 2.0 and PCI Express Mini Card wireless
     adapters based on the Ralink RT2501USB and	RT2601USB chipsets, including:

EXAMPLES
     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net

     Join a specific BSS network with 40-bit WEP encryption:

	   ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x1234567890 weptxkey 1

     Join a specific BSS network with 104-bit WEP encryption:

	   ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS
     rum%d: could not load 8051	microcode  An error occurred while attempting
     to	upload the microcode to	the onboard 8051 microcontroller unit.	The
     driver will reset the hardware.  This should not happen.

HISTORY
     The rum driver first appeared in OpenBSD 4.0.

CAVEATS
     The rum driver supports automatic control of the transmit speed in	BSS
     mode only.	 Therefore the use of a	rum adapter in Host AP mode is dis-
     couraged.

AUTHORS
     The rum driver was	written	by Niall O'Higgins <niallo@openbsd.org>	and
     Damien Bergamini <damien@openbsd.org>.
