WIFI 6 (Mediatek MT7921) disconnects randomly

Anonymous

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.

    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

    Lenovo System Update for Windows 11, 10 & 7 (32-bit, 64-bit) - Desktop, Notebook, Workstation - Lenovo Support GB

    If you install Lenovo System update make sure you disable automatic updates. Otherwise the working driver will be replaced by the problematic one and you are back to square one. Just confirmed on my brand new Lenovo T14S.

    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.
