Windows 7: Unable to access some folders on a NAS via wireless connection

[TheHibiscus]

I have in recent times installed Windows 7 64 bit on my two Desktop computers at home. They are connected by means of Ethernet to a router. As well connected to the Network attach Storage device. From these computers I am able to access files as well as folders on the common drive with no troubles. On the other hand, on my laptop that connects wirelessly, I can see all files and folders but I can access only few. I have tried enabling as well as disabling Home Group. I think this is somewhat associated to wireless security? Please assist!

Earlier than I bought Windows 7 I was using Windows Xp and had no trouble whatever to connect to my Network-attached storage (NAS) all the way through the Speedtouch. As a result, there seems to be somewhat about the mixture Speedtouch and Windows 7. But, since I declared before - a new firmware for my Speedtouch resolved it all. I am having v6.2.17.5. Is it the one you have?

Thanks for your valuable suggestion, unluckily did not make any dissimilarity. My doubt is that it's a trouble through the wireless adapter in my notebook as well as Windows 7. I have tried via all the dissimilar versions of the driver however not anything help. At what time I have some time I may attempt making use of a USB-Wireless adapter in place of the onboard wireless and observe if that formulate any difference.
