This does NOT include wifi onboard, I was provided an adapter for USB and it's only Draft N wifi 4 and BT 5.0 and some cheapie no name brand at that. The SSD is NOT a 512GB but a 480GB. This may not seem like much of a difference but the 480Gb are usually slower chips onboard the SSD than a TRUE 512GB.  Pretty sleazy of the seller not to mention the specs will be fulfilled via no name adapters and not actually onboard. I'll update as I go. So far the machines themselves SEEM to work ok, but I'll update as I find things unadvertised...Id not have paid this much if I'd known this...these can be got a little cheaper WITH AC wifi onboard so be careful.......
