.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 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.
|
|
.Pp
|
|
.Nm
|
|
supports
|
|
.Cm station ,
|
|
.Cm adhoc ,
|
|
.Cm hostap ,
|
|
and
|
|
.Cm monitor
|
|
mode operation.
|
|
Only one virtual interface may be configured at any time.
|
|
For more information on configuring this device, see
|
|
.Xr ifconfig 8 .
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports USB 2.0 wireless
|
|
adapters based on the Ralink RT2501USB and RT2601USB chipsets,

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver first appeared in
|
|
.Ox 4.0 .
|
|
.Sh AUTHORS
|
|
The original
|
|
.Nm
|
|
driver was written by

|
|
.Sh BUGS
|
|
Host AP mode doesn't support client power save.
|
|
Clients using power save mode will experience
|
|
packet loss (disabling power saving on the client will fix this).
