So we've just purchased a bunch of new network switches (3750's) and our Main computer lab uses WOL to turn on all the computers. The lab is very large, and the they span several VLAN's.
I'm assuming it stopped working after you put in the 3750s. Are you routing with the 3750s and weren't before? Did you segment the network in some way? WOL works on broadcasts. You may need to enter 'ip directed-broadcasts' on your Layer3 interfaces.
