MediaTek MT7921 Wi-Fi 6 802.11ax PCIe Adapter problems with internet connection after update

[Makc_Grek]

I guess the problem appeared after I got Windows updates in summer with system update + drivers for processor(? i guess yes) and drivers for the network card. So might be a problem with drivers, because home network is all-right, TVs, phones and other laptops are working well.
I thought that the problem was because of manipulations with Wi-Fi connection settings(MTU, package limits), but it's not, actually recovered deault settings and Wi-Fi keeps dying on its own sometimes.
Noticed that Wi-Fi dies when I start to download something or receive lots of packages. When it happens, Windows freezes for some seconds and shuts down Wi-Fi totally(I can reconnect to the network, but it's not just disconnecting from network, it absolutely turns off Wi-Fi with a service. But I don't need to do something specific, starts from basic buttons).
Today it even killed the Bluetooth services for a company with Wi-Fi when I was trying to download Forza Horizon 5 from Steam.

Well, bluetooth had a greatfull death. Restarted laptop and the service doesn't work.

Updated drivers. 
Bluetooth works, thanks for a driver. 
With Wi-Fi the problem didn't go away, tried to download Forza, it freezed Windows and crashed Wi-Fi.
Btw it's on multiple Windows versions, I have removed the update in summer, and after I already received and installed 2 new versions of Windows. Current version is 22H2 19045.6332

In the games I don't have any problems,  it never neither crashed nor freezed system. Only when downloading something.

I fixed the crashing by putting "highlyrestricted" in size of packages for TCP. Now it downloads the game on full speed without any problem.
Uhhhh.... Thanks for help, I'm actually happy.
