I tried 3 different wifi cards, none of them worked properly. Such a shame, the design of this minipc is nice. It looks and feels sturdy - but to even place the wifi card into the device, you have to completely disassemble it, and take the motherboard off the cpu cooling system -- so the glue/goop that secured the processor to the cooling unit gets disconnected just to insert the wifi card. horrid design. Have to send back for refund.
This is a quality product, but the product description and images does not convey any info about the wifi adapter provided in the options. I needed dual channel (2.4 and 5ghz) so I purchased 3 different wifi cards on Amazon, and all failed (no network could be found) -- only after a friend suggested, because of the solid metal box (good thing) the wifi signal is blocked. So I went and purchased rabbit ears and manually installed them on one of the wifi cards and boom - all was good. I was too harsh in my review here of a 1 star. This is a quality product - although, I still think having to completely remove the mboard to get to the wifi card slot is not good, and you disrupt some sort of glueing on the mboard it looks like directly on the processor. If I were to score again, the product itself would get a 4 star.
