.It Cm powersavesleep Ar sleep
For IEEE 802.11 wireless interfaces, set the desired max powersave sleep
time in milliseconds.
.It Cm protmode Ar technique
For IEEE 802.11 wireless interfaces operating in 11g, use the specified
technique for protecting OFDM frames in a mixed 11b/11g network.
The set of valid techniques is
.Dq off ,
.Dq cts
(CTS to self),
and
.Dq rtscts
(RTS/CTS).
Technique names are case insensitive.
.It Cm rtsthreshold Ar length
For IEEE 802.11 wireless interfaces, set the threshold for which
transmitted frames are preceded by transmission of an
RTS
control frame.
.Ar Length
is the frame size in bytes and must be in the range 1 to 2312.
Not all adaptors support setting the RTS threshold.
.It Cm txpower Ar power
For IEEE 802.11 wireless interfaces, set the power used to transmit frames.
.Ar Power
is a unitless value in the range 0 to 100 that is interpreted
by drivers to derive a device-specific value.
Out of range values are truncated.
Typically only a few discreet power settings are available and
the driver will use the setting closest to the specified value.
Not all adaptors support changing the transmit power.
.It Cm wepmode Ar mode
For IEEE 802.11 wireless interfaces, set the desired WEP mode.
Not all adaptors support all modes.
