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.

    I uninstalled my current driver, that removed the option to select it from the device manager. Restarted the PC to auto-install and get the device back to try again, and the auto-installer had installed this new driver. So far, not impressed. Pretty much the same issues as before. The device breaking randomly and forcing me to restart, sometimes multiple times before it actually behaves. Is it possible that the other drivers still stored on the PC might be interfering somehow? Since there is an option to delete all the driver info when uninstalling the device. The closest thing I've gotten to a fix so far was something this one video recommended involving going through the command module and wiping something or other clean (not any files as far as I understand, just something in the deeper hardware that was getting clogged up). I can't seem to find that video again though.

    hi, in several posts in this thread I and others have detailed how to install the driver that we have recommended. The auto-installer will simply revert back to the same broken drivers provided by the manufacturer (which appears to be the problem). I would recommend reading some of the previous posts that detail the process and do that. Go to device manager. Locate the device. Uninstall it and remove the driver. Do not restart. Use the device manager to reinstall the device and manually select the driver that has been recommended by several people on this page (specifically one from Lenovo). Once it is installed it should begin working again, provided it is the same problem and same device that has been the discussion of this thread.

    Hi Ojashwi,

    Based on my experience and the solution which has worked for many people, it seems that this issue is brought upon either by a driver provided through the manufacturer or through windows update. There are several people who have provided links to a driver provided by lenovo which seems to work for other computers such as Asus and HP which seem to have this problem. I would download that. Then go to device manager, locate the network device, and uninstall it completely removing the old driver. Do not restart. Instead, right click the device again and proceed to install the new driver that we have described. Do not automatically search for it. The one that Windows thinks is best seems to be faulty. Instead you will need to manually locate the one that we recommend from Lenovo. After this it should begin working with no restart needed. I hope it works for you.
