Standby & wake on lan -problem

[Matti Heiskanen]

Hello,

I'm running a web server on my Win XP SP1 machine. To enable waking of the
computer from standby by requesting a web page on the web server, I've set
NIC Power Management option to "Allow this device to bring the computer out
of standby."

This works fine, only now my problem is that the computer resumes from
standby by itself in every few minutes even when there is no network traffic
between the computer and internet.

If I unplug the computer's network cable from the external adsl modem, the
computer won't resume from standby by itself, but obviously neither can the
computer be connected from internet.

Or if I change NIC Power Management options to "Only allow management
stations to bring the computer out of standy.", the computer won't resume
from standby by itself, but needs a magic packet to wake up. However the
magic packet -scenario is not implementable in my case.

Could it be that the network traffic between the computer and the external
adsl modem is causing the computer to wake up? If so, how can that be
avoided other than using the ways described above? Or is there some other
source that is triggering the NIC to wake up the computer?

There is always "idle traffic" at any Internet connection.

You might be able to control it by using a Cable/DSL Router or a more
expensive Firewall appliance that might be able to block most of irrelevant
pings etc.

My experience shows that for general purpose, i.e. to let other people log
to the Site. Leaving the computer on standby does not save much and inserts
an unnecessary delay.

For personal purposes I rather use WOL and Hibernation:
