Waking up Network

If idle for 10 min. one of my desktops fails to show in the

Phoenix BIOS (for IBM 8113 M52) has no flag to "Wake on
LAN." I have the Solar Tools WakeOnLAN.EXE to send
wakeup calls on demand but it does not work all the time.

Is there a better way?

Some wireless MAC chips, are "smarter" than others.

The more modern ones, have their own processor of sorts
in the MAC chip, and those, if the OS is asleep, can
continue to participate in wireless networks. And listen
for things like WOL.

But in this case, maybe it's a matter of going to Device Manager
in Windows, and disable "Allow the computer to turn off this
device to save power", for the device that is disappearing.
In the item for the Wifi hardware device, see if the
Properties have a Power Management tab.
