Thanks guys, the situation has however resolved itself. I took advantage of a Free Tune-Up offered by a local computer retailer, this was really nothing more than a Virus and Registry scan, and being almost new nothing showed up of course, but afterwards the subject WiFi connection worked.
No answer to that (that I can think of ) maybe some garbage loaded on to the computer as part of the original sales package was removed.
Cheers,
