Wake On LAN tends not to work with Wireless NICs because there is no
power sent to the Wireless radio when the PC/laptop is in standy/sleep
mode.

On an IBM Thinkpad, you'll see the Wireless led on the lid go off when
the system is in standby. That means the radio has been shut down to
save power.

Compare this to an ethernet NIC in a PC, where you'll see a link light
on even when the PC is in standby.

Think about, the NIC must be "awake" to pickup the magic packets on the
LAN.

There was a Wirless adapater for a PC mentioned on these forums that
did support WOL. It was PCMCIA card in an adapter on a PCI card. It's
the only wirless card that I've even seen to support WOL.


The other problem was that WinXP would only stay awake for about 5
minutes before going back to sleep. I contacted Microsoft support, but
they basically fobbed me off. There is a KB article on Microsoft's
support site which describes the issue and it's apparently meant to
work that way "by design".
