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.

    Hi Ashkat,

    It seems that the most successful "fix" for this has been changing drivers... In most circumstances, using whatever "newest" driver that the PC maker recommends is the way to go. However, with this device, it seems to be causing many problems. For example, the HP drivers are causing my internet to disconnect all the time. It has been found that other drivers provided through other PC makers seem to work a lot better. I am using the driver found in the link below:

    https://dl.driverpack.io/driverpacks/repack/WLAN-WiFi/MediaTek/FORCED/10x64/79xx_3.03.01.0508/MediaTek-FORCED-10x64-79xx_3.03.01.0508-drp.zip

    However, in order to download it you will likely need to uninstall whatever driver you are currently using and manually install this driver. People have explained how to do this through the device manager in previous responses. I hope it works for you.

    Hi Ben,

    I had the same issue as well. My computer went back to restarting itself pretty much anytime that it was left unattended or put to sleep. I uninstalled the driver and downloaded the other one that somebody provided through a website called DRM or something like that (if you read previous responses, you will eventually find it). It was a bit newer. Since then I have had no problems again. It seems like it is a driver/windows compatibility problem... but time will tell.

    Is this referring to the mediatek 3.3 update linked to by Prem?
