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.

    Awesome! I'm glad that it is working for you! Seems like both HP and Asus seem to have bad drivers. I can't help but to wonder if these bad drivers were provided to them by Mediatek...

    I am that that this was able to help you! The crazy thing is that many other computer makers are not offering the most recent driver that works, but are still offering the older one which appears to be corrupt.

    I am glad that it worked for you. This really is strange that the device drivers that are being provided with this seem to be defective. I've never had a problem like this before in my life. Since I installed the lenovo driver that I mentioned, I have only had to run the windows troubleshooter to reset the device 1-2 times as compared to about 10 times a day with the other driver. I'm pretty convinced that the drivers that were provided were bad. The Lenovo one might not be perfect, but had made a huge improvement. I'm hoping to find a future driver that will iron out all of the bugs.
