At first, I was a bit skeptical but the card works and works great. Signal quality shows full strength being connected to a modem 8 m away behind two (thin) walls. Speed shows 866.7 Mbps rarely dropping to hundred something for a split of a second. I haven't investigated if I could achieve the full advertised speed. Seems like a waste of time when my internet connection isn't anywhere near that. Arrived in less than a month
tested and everything is fine and working!
