Very disappointed - works poorly
My old PC is fitted with an Intel Dual bande AC 3165 Wifi card from which I can only download 30 to 70 Mb/s, whereas my box delivers more than 600 Mb/s (in real time) with a network cable, which is why I decided to install a new card with better performance and better reception with its antennae.
No problem on installation and the "Wifi Status" dialogue box shows a speed of 520 Mb/s (great) (max 120 with the old card).
The only problem was that when testing downloads, I didn't exceed 8Mb/s (or even less than 1Mb), with serial connection losses, including when simply surfing (I'm not even talking about online games).
So I reconnected the old card, which is very stable.
Fortunately, the card wasn't expensive
