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.

You also need to ensure all drivers are downloaded on windows update, ensure that you have also updated the power management and bluetooth drivers are updated.
Is it a thinkpad laptop if so you can install Lenovo System update
If you install Lenovo System update make sure you disable automatic updates. Otherwise the working driver will be replaced by the problematic one and you are back to square one. Just confirmed on my brand new Lenovo T14S.

Update: I've swapped routers, motherboards and tried every driver known to exist. My problem still persisted. i was to the point of trying a fresh install of windows but I was still looking for alternatives. I decided to try and update to windows 11 as a last ditch effort before doing a clean sweep of my system. since upgrading to windows 11 I haven't had a single WIFI failure and that was 2 weeks ago.
If you've tried everything else it might be time to do the upgrade or do a clean install and make sure you have the appropriate drivers saved on a thumb drive. I hope this helps.
