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.

    I have got the same issue with a asus tuf gaming 17 inch laptop best it to reset the card in device manager. I use devmanview from http://www.nirsoft.net/ it can create a batch file to disable to re enable the driver which forces it to reset.

    Thanks for the clarification.

    Do you have any third-party security software (Antivirus/Firewall)?

    If so, temporarily disable it and see if the problem stops occurring.

    If it persists, perform a clean boot to see if any third-party program in the background is causing this problem. Follow the instructions carefully.

    https://support.microsoft.com/en-us/topic/how-t...

    If the problem does not occur after a clean boot. In this same article, there is a technique to help you identify which program is causing this in "How to determine what is causing the problem after you do a clean boot".

    After finding the cause or if it does not help, return to normal boot as instructed in "Reset the computer to start normally after clean boot troubleshooting".

    Thanks for the clarification.

    Is your Wi-Fi set to Public or Private?

    If it is set to Public, set it to Private and see if the issue will continue to occur.

    https://support.microsoft.com/en-us/windows/mak...

    If it persists, when the problem occurs, run the network troubleshooter.

    1. Click the Start button;
    2. Select "Settings > Network & Internet > Status";
    3. Under "Advanced network settings", select "Network troubleshooter".

    If any error messages are displayed, let me know.
