.Sh NAME
.Nm ural
.Nd "Ralink Technology RT2500USB IEEE 802.11 driver"
.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 ural"
.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_ural_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports USB 2.0 wireless adapters based on the RT2500USB chipset.
.Pp
The RT2500USB chipset consists of two integrated chips, a RT2570 MAC/BBP
and a radio transceiver (the model of which depends on the card revision).
.Pp
The RT2522, RT2523, RT2524, RT2525, RT2525e and RT2526 radio transceivers
operate in the 2.4GHz band (802.11b/g) whereas the RT5222 is a dual-band radio
transceiver that can operate in the 2.4GHz and 5.2GHz bands (802.11a).
.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 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).
