Any insight on why I would be able to connect using just the "dlinkap" before, and not now? (still doesn't work that way) Not that I'm going to mess with it now, more curious than anything.
Well since you're using two of the same models, they might be conflicting with each other (Two dlinkap on the same subnet). You can change the name of the device by clicking the "Setup" tab on top, then "Network Settings" on the left hand side. The last option should be the name. Change one of them to "dlinkap1" for example. Power cycle it then give it a shot.
Also, you may want to verify upnp is installed on your system. When you were directly plugged into the DAP your O/S may not have been recognizing it 'automatically.' You just have to go into the add/remove programs then add/remove windows components to the left. It's under "Networking Services" (I think). Just make sure upnp is checked.
I'm glad you have them working again!
