Oops. I wrote all the stuff below because I misread that your server was the ASUS X54C, but now rereading I see that the X54C is the client, trying to wake the server. Oh well, read this stuff and it may help. At least it confirms that the X54C does support WOL.
But now, tell us about your server. In particular, the motherboard brand, model, version, and if applicable, the network card in it, or the brand and model of built in Network Interface Card (NIC). Get this from the Device Manager if you don't know from elsewhere. Also see if you can find out the brand, model, version of the wireless card in your server.

Okay, the Asus X54C has either one of the Atheros AR8131, AR8132, AR8151, AR8152 network cards. According to the latest network driver for the ASUS X54C, the network card supports "Wake Up Capabilities", with both MagicPacket & PatternMatch capabilities, but it is turned off by default. So you need to turn it on.
So when you said you have set up the correct properties, did you go into;
Control Panel -> Network and Internet -> Network and Sharing Center
Click on he "Connections: Local Area Connection" which opens the "Local Area Connection Status" dialogue.
Click on the Properties button
Click on the Configure button (You can get to this point by opening Device Manager and double clicking the Network Adapter as well.)
Click on the Advanced tab
and scroll down to find the relevant WOL settings and turn them on? The settings might include;
Shutdown Wake-On-Lan
Wake on Magic Packet
Wake on Pattern Match
WOL & Shutdown Link Speed
The settings may be a bit different for you. The above are what my Realtek NIC has. Here is a ASUS with Atheros on VISTA setup description:

While you are looking at the Configuration, go to the Details tab, and find the "INF Section" and "Hardware Ids" properties. With those you can work out from the INF file which network card you actually have.
Once you have made the above changes, save them, reboot your laptop, then go all the way back into the Configure Dialogue, and this time go to the Power Management tab (instead of the Advanced tab). Make sure that the settings are correct here. Mine are;
Tick: Allow the computer to turn off this device to save power (Required for the next setting to be available, and not greyed out.)
Tick: Allow this device to wake the computer
Optional: Only allow a magic packet to wake the computer (Probably a good idea. Ticking this would just disable the Pattern Match method.)
Save all those changes, if any, and reboot.
Now that you have that working, here is a description of how to get WOWLAN working in Windows 7, if the wireless card supports it.

Note that the ASUS X54C can have one of three brands of Wireless LAN Adapters, from either Intel, Atheros, or Foxconn, as shown on this page:

You could try following a similar procedure to above for the WLAN and see if you can get WOWLAN working, or look up in Device Manager and let me know which brand you have, and I'll see if it supports WOWLAN.
