Ive had the WiFi problem too, i have it already for a long time 2 or 3 times in a week (months ago the issue started) on my Medion P15648. After unplugging charger and let laptop shut down for few hours, Wifi came back. But since one week ago, this dont fix the problem anymore. I already deinstalled drivers and reinstalled them from Medion default drivers and from latest Intel Wifi drivers, but not working, also i did a network reset in Windows and bios reset to defaults , but both didnt fix the problem.
I think thay all of this issue has to be made with the fact that I bought the laptop somewhere in 2017 with AC Wireless 9462 , and it has got an update to WiFi 6 AX 201 Mph. Its always because of this fkin updates that stuff dont work anymore.
For now Im already 1 week without wifi on my laptop. Even when I could fix this (i almost gave up), i will never buy microsoft laptop anymore!
