Hello everyone
I always wanted to share the solution of the mighty asus wifi mystery
First come first the wifi disappearance you have to open the back panel remove the wifi card and reinstall it right away tightly. This will solve all your issues of wifi driver.
Second for low speed you have to download the intel driver Intel® Wireless Wi-Fi Drivers for Windows® 10 and Windows 11*
now you are all set
do let me know if it helps
