Maximum Sleep Duration 4
The Maximum Sleep Duration identifies the “listen interval” (in
milliseconds) for WaveLAN cards in sleep mode. At the specified
listen interval, the WaveLAN card will “wake up” and check to see if
there is network traffic addressed to your station.
The default setting is 100 milliseconds (ms). For notebook and
desktop computers, we recommend that you do
not change this
value, since this may interfere with standard operation of your
Network Operating System. Hand-held devices may consider
higher values, but first check the user manual that came with the
device.
Receive All Multicasts 4
When multicast frames are sent to the WaveLAN card, the card will
be prompted to “wake up” at regular intervals to receive all
multicast frames from the network.
The default and recommended setting of this parameter is enabled
to receive all multicast frames.
When using Power Management on a networked computer, we
advise you not to disable the “Receive All Multicast” option, unless
you are absolutely certain that neither the application, nor the
higher layer protocols of the network system need multicast
messages for proper communication (for example, in a single-
application, single-protocol system like a hand-held scanner).
!
CAUTION:
Disabling the “Receive All Multicast” option for networked
computing devices in regular networking environments
may affect the performance of your computer. Missing too
many Multicast messages might result in losing your
network connection.
