.Sh NAME
.Nm rum
.Nd Ralink Technology USB IEEE 802.11a/b/g wireless network device
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ehci"
.Cd "device uhci"
.Cd "device ohci"
.Cd "device usb"
.Cd "device rum"
.Cd "device wlan"
.Cd "device wlan_amrr"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_rum_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports USB 2.0 and PCI Express Mini Card wireless adapters based on the
Ralink RT2501USB and RT2601USB chipsets.
.Pp
Ralink PCI Express Mini Card adapters show up as normal USB 2.0 devices and are
thus handled by the
.Nm
driver.
.Pp
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.
.Pp
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 throughput.

.Sh EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
.Pp
.Dl "ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00"
.Pp
Join a specific BSS network with network name
.Dq Li my_net :
.Pp
.Dl "ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net"
.Pp
Join a specific BSS network with 40-bit WEP encryption:
.Bd -literal -offset indent
ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
wepmode on wepkey 0x1234567890 weptxkey 1
.Ed
.Pp
Join a specific BSS network with 104-bit WEP encryption:
.Bd -literal -offset indent
ifconfig rum0 inet 192.168.0.20 netmask 0xffffff00 ssid my_net \e
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.It "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.

.Sh HISTORY
The
.Nm
driver first appeared in
.Ox 4.0 .
.Sh CAVEATS
.Pp
The
.Nm
driver supports automatic control of the transmit speed in BSS mode only.
Therefore the use of a
.Nm
adapter in Host AP mode is discouraged.
