so is it a 802.11 n or not?

801.11n was not actually certified as a universal standard until October 2009 - which is after your VGN-NW20EF was first released.

Between 2006 and October 2009 there were a few different Draft N standards.  The final version is backward compatible with the previous draft standards.

As your Vaio was released just before final certification, I have no doubt that your Vaio will be compatible with the new certified 802.11n standard and should connect OK to a new a/b/g/n router.
