WIFI 6 (Mediatek MT7921) disconnects randomly

I just finished building a new pc and installed all the appropriate drivers and software. I have a WIFI 6 router which I have had for a while now and never had any issues with and the motherboard I am using is the ASUS TUF GAMING B550-PLUS WIFI II AM4 AMD B550 SATA 6Gb/s ATX AMD Motherboard. It utilizes the Mediatek MT7921 WIFI card.

The WIFI will randomly disconnect but it says its still connected. Oddly enough I can still load Google and Youtube but nothing else and even then that is intermittent and extremely slow.

Drivers: Ive tried updating, rolling back, deleting and fresh install. no dice

Settings: Ive tried disabling IPV6, Changing from AX to AC to N, etc, Disabled the Bluetooth since its the same adapter. no dice.

Ive even checked to see on another device if my pc is connected to my router while its in this disconnected state and it shows that its connected to my router but it will not connect properly to the internet. I have not had this issue with any other device on my network so I am to conclude that it is most likely to do with this new pc and this Mediatek WIFI Adapter.

Any and all help is greatly appreciated.

    Goto Microsoft Update Catalog Do a search for 22.30.1.1342 (this version is working for me) (its the most recent for Window 10 at this moment in time.

    Download the cab File file

    Start > run > appwiz.cpl (as an admin).

    uninstall any Mediatek software and reboot.

    Start > Devmgmt.msc (as an admin)

    scroll down to network adapters expand

    Right click MediaTEk WiFi 6 MT72921 Wireless card and select (un-install), (only do this if you have another method of connecting to the internet,

    Click Start > Settings > Updates and Security > Windows updates Check for Updates

    Additional Updates > Expand drivers and select all Drivers (including the media TEK one.).

    If not picked up as part of windows update

    Start > Rum > DevMgmt.msc

    Expand the missing driver right click properties > Driver > Update driver browse to the cab file you downloaded earlier.

    Also do the same thing with the bluetooth driver

    That didn't work for me on a brand new Lenovo laptop.
    Jeremyb777 solution rocks!

    You also need to ensure all drivers are downloaded on windows update, ensure that you have also updated the power management and bluetooth drivers are updated.

    Is it a thinkpad laptop if so you can install Lenovo System update

    I have Asus TUF Gaming that I bought last Spring and I didn't have any issue with WiFi not until the Windows 11 update last summer.

    I saw your solution this afternoon and gave it a try but it didn't fixed the issue. It works for a while, and then it didn't.

    I have this D-Link WiFi dongle/adapter I bought several years ago and supports 802.11 ac for both 2.4 and 5G, I guess this is my ultimate solution for now until Microsoft or ASUS fixed this issue. I never have any issue with WiFi eversince. I disabled Mediatek MT7921 and plugged the dongle in the USB drive.

    This is a hassle, specially to my wife who in her online class now. She once almost failed in one of her class because the internet was lost in the middle of her timed online exam.
