My previous comments were that it had NO WIFI...As I was packing the unit to send back a small plastic packet was stuck to the plastic bag, it said "USB WIFI" and it plugged into a USB port and I had WIFI.. The instructions  and peoples comments said there was no WIFI...Now if the instructions said to use the included WIFI adapter I would have not seen it and sent the PC back..It's working so far and getting it set up, so far so good...
