My new Win 7 laptop cannot connect to external NAS via my home wireless network, but my old Win XP laptop access it pefectly. My wife has a laptop with Vista and cannot access it either. The NAS works ok because my old laptop with XP and another Win XP PC I have connected to the wireless network operate perfectly with the external drive. With the Win 7 laptop was unable to map the NAS. The system says that "cannot connect" Any clues/ guide of how to fix this issue? Thanks a lot!

Hi, Try this: 1. Open "Network and Sharing Center" 2. Go to the "Local Area Connection Properties" 3. Ensure "Client for Microsoft Networks" is ticked It works for me, hope it works for you too!
