It's funny that on the SONY website they have a later date listed, refer to an update, and then have the same version number as before. Very confusing! See attachment. I tried going with the manufacturer's sites a few years ago and it was disastrous, for another Vaio that was spectacular. This one has very good specs and perks but these problems have taken a lot of my time and productivity. Thanks for the advice, but maybe I should get with SONY and ask them if they have other updates (chat live online).
As to the Bluetooth you mentioned, yes, that is the other intermittent problem with this unit. Interestingly enough, when turning off the WiFi (switch), Bluetooth is also not active, so the link is there too. Maybe that is the problem? I'll give that a shot, as well. Will let you know.
