    @minhdaang123,

    Open Command Prompt (as Administrator) and running the following command:

    netsh int tcp set global autotuninglevel=normal
    

    The cmd above solved the slow speed with Intel Wi-Fi AX200 adapters, <here>.

  • Have you tried resetting the router settings?

    Finally resolved the problem. I had to disable the ethernet and the microsoft virtual adapters in device manager. I dont know why they interfere with the 5Ghz wifi. Now everything works fine again. Took me 1 year to fix this problem.
