Is Wake-on WIRELESS lan possible?

Im setting up a media server and when im not home it some times shuts down but its a wireless mb, I have read threads saying I need to create a "registry key" or "enable magic packets" but Im not sure if that would solve my issue.

any ideas?

Unfortunately Wake on LAN only works with WIRED Connections. Because wired connections are always "connected" to the router even when the device is powered off, whereas a wireless device will connect and disconnect from the router and so can't be "woken" because it is not there to wake (think of it like a landline phone and a mobile phone, the landline phone will always ring because it is always connected to a phone line, whereas your mobile phone won't always ring because it can be turned off or out of signal and so not connected to the network, hence it is not "there" to ring).

Try modifying the advanced power settings to prevent it from going to sleep or hibernating at all, or set it so long that you will be home and using it before the time it is due to go to sleep or hibernate.

Wake on Wireless LAN is possible but it is hardware/driver dependent.
You would need to test if your wireless device does support Wake on Wireless LAN.

See this MS technet article:
Configure Wake on Wireless LAN (WoWLAN)

Note this warning in the article:
Warning Support for Wake on Wireless LAN in Windows 7 drivers is optional and some drivers might not support this functionality. If you follow the process and the option to enable this is still grayed out, then your driver does not support this functionality. Follow up with your hardware manufacturer for support information.
Create a Registry backup (and preferably a System Backup Image) before making changes so you can easily recover if anything goes wrong.
