This is an external DSL phone modem connected via ethernet cable to computer.
Modem does not have an on-off switch so I need to pull the power plug to
turn it off. Not a good idea. .... Seems like the modem is trying to arouse
the computer once in a while. Like a wake up call from the front desk. Got
to turn that off somehow. Thanks for the responses.
You can have a look in Device Manager.
For example, I have one entry under "Network Adapters".
If I do "Properties" on it, there are some options.
Under Advanced, I have "Wake Up Type". The option is
currently set to "OS Controlled". (Sometimes, you might
have the option to set that to None.)
Next, in the "Power Management" section, I have "Allow
this Device to bring the Computer out of Standby". That
is not ticked, so the computer cannot awake based on
what happens to the NIC chip.
In the BIOS, you'll have "Wake on PME", or perhaps
"Wake from PCI device". That controls the signal that
the NIC would be using to alert the computer that
a wakeup event (Magic Packet or whatever) had been detected.
Some NIC chips have the option to wake up on virtually
any event (such as the arrival of any packet, or even
a change in link state, such as plugging or unplugging
the Ethernet cable while the computer is asleep). Your
job is, to find in either the Device Manager or in the
BIOS, enough options to stop it.
