Question : Wake on LAN almost never works.

I have a Windows 7 computer that goes to sleep when it is inactive and I need to be able to wake it up on demand.  Once in a while, I can wake it up with just a ping command or using Wake On Lan software.  90% of the time, though, the computer just won't wake up for anything, unless a key is physically pressed on the keyboard.  WOL is enabled in BIOS and in Windows device manager.  The computer is connected to the network with an ethernet cable and not wireless.  Why does this happen and how can I fix it?

Thank you

Answer : Wake on LAN almost never works.

You need to use WPA2/AES in WLC and client config. You need AAA server setup in WLC. verify ur config with this http://araihan.wordpress.com/2010/04/30/complete-guide-to-build-a-cisco-wireless-infrastructure-using-cisco-wlc-5500-cisco-1142-ap-and-microsoft-radius-server/
