|
|
.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 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
|
|

|
.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.
|
|

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).
