I don't have network lock enabled, I have WPA2 with a Pre-shared key, so no need for locking the network. Yes, I even uninstalled it and reinstalled it. My PS3, and the other laptop both connect without any problems, my phone as well. It just seems to be that computer refuses to connect usning the DWA-552 adapter. The computer I'm trying to connect it with is running XP Home Edition, with SP3 installed.
I have a very similar issue here. I also have a DIR-655, WPA2 with Pre-shared key. I have two PCs with DWA-552. One of them always connects (XP SP3) and another one (Vista SP1) doesn't always connect after resuming (the same computer was before on XP SP3 and same issue). The authentication fails, the card sees the network but it doesn't authenticate. I have drivers 1.40 installed. No network magic or filter here.
