WIFI 6 (Mediatek MT7921) disconnects randomly

I'm sorry that my suggestions didn't help you.

I'm out of ideas about this issue.

But do not worry, as this is an open community, maybe someone has another idea that can help you.

Best regards.

I have got the same issue with a asus tuf gaming 17 inch laptop best it to reset the card in device manager. I use devmanview from http://www.nirsoft.net/ it can create a batch file to disable to re enable the driver which forces it to reset.

I have a newly purchased HP Pavillion laptop with the wifi adapter (Mediatek MT7921). It would frequently lose internet connection, then not show any networks available, then seem to disappear for a few minutes, and then reappear. I believe windows was detecting that the device would stop working, then attempt to restart the device driver. I tried everything... updating drivers, uninstalling, reinstalling, as well as pretty much everything that you said. I eventually started getting Blue Screen of Death. The strange thing is that when I ran a component test in the BIOS, it would always pass.

I even performed a couple of HP Cloud Recovery Factory Resets... but this didn't fix it either. Even before I ran any updates or installed any programs, the problem persisted on a factory reset machine. I began to theorize that maybe the driver that HP included with their recovery image and on their driver server was somehow corrupted or defective. I then determined to download a Windows 11 ISO directly from microsoft (and not HP) and let microsoft find drivers. This went well until I could not complete the setup process because it didn't detect any wifi networks. Turns out that the Windows ISO didn't have a proper driver either. There was a way to open up a command line and install a driver through there. So I looked online and found another driver (not sure from which provider) which worked enough for me to install Windows 11. But then again, on a fresh installation of Windows 11, I had the same problem. I then decided to try another driver. I downloaded a driver called "MediaTek-FORCED-10x64-7961_3.00.01.1309_lenovo-drp" that I found on a third party site. Upon closer review, I think it actually might be for a slightly different adapter... Anyways, I removed the other driver and updated it to this one and kept my fingers crossed to see what would happen.

Well, 30 minutes went by, then an hour, then 2, then several... then overnight... then all day so far today I have not had a single problem. Normally, if I open up windows event viewer, I will see tons of errors related to the networking and internet. However, there are little to no errors being reporting and the internet has not stopped working once. This makes me think that my theory may have been correct... that maybe there are some faulty drivers being provided through HP and maybe even ASUS... I don't know... However, I would encourage you to try finding the driver that I mentioned and give it a shot. I was about to give up on this computer and/or just install linux, but this seems to have solved the problem.

unfortunately I couldn't get that driver to download. there was only one website that had that driver and it wouldn't load properly.
