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.

    Hi Reader,

    I even done the reset the problem still exist

    My Laptop is Asus Tuf Gaming F15 and my laptop is still in warranty so I called asus customer care.

    the service enginner also said that all data will be removed so pls backup your data

    I backed up my data he also done the factory reset but issue still persist.

    and he said we have to replace wi-fi module (hardware part) and he got replaced it the problem is fixed after replacing

    I suggest you do the same.

    I definitely recommend trying different drivers for these MediaTek WIFI cards as some of the drivers are in fact faulty. Also some people have had success with changing the DNS settings and flushing the DNS in command prompt. I was originally under the impression that only one device was affected by this problem. I also noticed that my phone (S21) automatically jumps to the 5Ghz channel of my router automatically but loses the WIFI 6 functionality. So I still have WIFI on that device its just a little slower. My pc however wont jump over to the other channel and when it tries it fails to connect and the only solution is to restart my PC. I narrowed it down to the router based on what I noticed once I reset it in the app. my router has an app and the typical IP address to access the settings. When I reset the router thru the IP access point nothing changed and all of my other devices reconnected normally. When I reset via the app I noticed both my phone, my wife's phone and my PC would not reconnect. They all showed they were connected but none of the devices actually had internet. That's when I realized that the router was what they all had in common.

    Now I still haven't received a new router since I found this over the weekend. I will update once I receive it and let everyone know if it worked or not.

    Hi,

    I had no idea what you were talking about as the file itself is a zip file... Then I redownloaded it and saw that a random graduation pic had made it's way in there... Haha. I have no idea how that happened. Anyways, if you still have it, there is also a folder inside called Mediatek. Just keep opening the folders til you find the files. The one ending in the .inf file is the driver. What you would need to do is go to the windows device manager, find network adapters, and right click the mediatek one. Click "uninstall device." Then afterwards, reinstall it. Windows will ask which driver... You will then locate the one I provided an use that. Anyways, I'll remove that file from filedropper as it has a graduation pic which wasn't even mine, but should have never been in there. Again, not sure how it happened! Sorry about that! The following link should be better without the unnecessary folders and graduation pic.

    So, I did try your suggestion to download the driver from the link you posted: https://filedropper.com/d/s/WljNznfQMIlOHZQqur0wDmdl95GY6g.  Unfortunately, I did not find a zip file in that download, but then again, I already mentioned I'm not as proficient as others. I DID like the graduation pic, though!
