I have a brand new laptop and its wifi card is Intel AX200 wifi 6 when I speed test near the wifi which is on the secondfloor of our house it reaches 70mbps then after a few seconds it drops to 50-55 mbps which is fine because our wifi plan is really 50mbps only but when Im at the ground floor of our house its only 1-10mbps when my phone and other devices still reaches 40-50mbps. I tried to change the wifi driver but when I try the other versions even when im at the second floor it only reaches 1-5mbps and when I use a usb wifi dongle at the ground floor it reaches 25-40mbps. What do you think is the problem? Is the wifi card faulty?

You may have to change the orientation of the antenna on the router so it transmits down for a lower level.. If it doesn't have external antenna then change the orientation of the router. Looking at your signal strength may give you a clue if something changes.
