21.Sh NAME
22.Nm ural
23.Nd "Ralink Technology RT2500USB IEEE 802.11 driver"
24.Sh SYNOPSIS
25To compile support for the
26.Nm
27driver into your kernel, place the following lines in your
28kernel configuration file:
29.Bd -ragged -offset indent
30.Cd "device ehci"
31.Cd "device uhci"
32.Cd "device ohci"
33.Cd "device usb"
34.Cd "device ural"
35.Cd "device wlan"
36.Ed
37.Pp
38Alternatively, to load the
39.Nm
40driver at boot time, place the following line in
41.Xr loader.conf 5 :
42.Bd -literal -offset indent
43if_ural_load="YES"
44.Ed
45.Sh DESCRIPTION
46The
47.Nm
48driver supports USB 2.0 wireless adapters based on the RT2500USB chipset.
49.Pp
50The RT2500USB chipset consists of two integrated chips, a RT2570 MAC/BBP
51and a radio transceiver (the model of which depends on the card revision).
52.Pp
53The RT2522, RT2523, RT2524, RT2525, RT2525e and RT2526 radio transceivers
54operate in the 2.4GHz band (802.11b/g) whereas the RT5222 is a dual-band radio
55transceiver that can operate in the 2.4GHz and 5.2GHz bands (802.11a).
