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.

    THIS IS ABSURD!! This problem was caused by a Windows Update. For me is the second time to have problems with those updates. I really need to fix this problem a soon as possible. I need my wifi connection to work. I'm not an IT professional to solve a programing issue.

    I think it's pretty much confirmed that there must be some defective drivers being deployed through HP and Asus. The Lenovo ones seem to be working better. However, I still have an occasional issue with the wifi... but thankfully the windows troubleshooter seems to fix it. I think all it does is disable and reenable the device.

    Although there is a joke of the Windows troubleshooter never fixing anything, I've seen it actually fix network issues before. That's the one thing it might fix lol. It is indeed 99.9% worthless.

    But, it won't fix a driver issue lol. That's for a different driver to fix. MediaTek usually if not always should have a good working driver available. I've only ever seen them do a great job with that. So when in doubt look for a new driver.

    The Network troubleshooter has been carefully developed to run a series of thorough tests that will result in this Troubleshooter not being able to solve the problem 😂

    Hi. I'm Prem.

    I own ASUS TUF F15 which has the same WLAN Card that you've mentioned.

    Even I had the same issue.

    So I installed latest driver of MediaTek 3.3

    Now the issue has been resolved!

    Here's the link for the driver : https://rog.asus.com/forum/showthread.php?124328-DRIVERS-MediaTek-WiFi-Bluetooth
