I've created a bootable usb stick, under windows, and checked the disk is OK. Load the try Ubuntu option and, as with 11.04 and 11.10, it can't find the D-Link adaptor.
It seems driver for this USB wifi adapter doesn't work "out of the box" as said on the official Ubuntu support page. Check this guide: http://www.konopolis.com/blog/ultimos/instalacion-de-d-link-wifi-usb-dwa-140-en-ubuntu-12-04-lts.html
It's in spanish but commands worked fine for me. Regards.
