MediaTek Wi-Fi 6 MT7921 Wireless LAN Card disconnects (SOLVED)

[Lexaria]

hello my MediaTek Wi-Fi 6 MT7921 Wireless LAN Card disconnects every 11-12h also it has Lag Spikes, its only in  the game League of Legends in WOW it is working what should i do? i have newest drvier software from 2.2.23

EDIT: Solution:

Hello i finally found an solution for that problem.

1. Download this version of the Driver https://rog-forum.asus.com/t5/amd-600-series/drivers-amd-mediatek-wifi-bluetooth/td-p/857576/page/8

2.Go in Device Manager - Networkadapters and select properties at Mediatek Card

3. change at advanced from 8.02.11ac to AX and its fixeD!

did you find the solution? i tried to change to AX to AC as the guy mentioned because i already have it on AX so ill see if everything goes well, im facing this problem 2 weeks ago, first it was the bluetooth device it started to do the same thing, disconnecting everytime and even disappearing, then on MyAsus it showed up new driver INTEL SST and it fixed it, you can try this tutorial, you just need to rollback the wifi driver to 0508 version https://www.youtube.com/watch?v=F8Q_Y_pjdk4 

it works but another problem pops up, when play online ur ping starts to going up from 45 to 500 ping for a couple of secs and then it goes back to normal so is up to you if you want to play in that way

btw you can try the hard reset method, personally i dont wanna try it unless i have no more solutions and another suggestion that you can try is that everytime the wifi disappear you can go to device manager and try to rollback the driver to another version it doesnt matters which one and it starts to work again but the issue it will still persist but you dont have to restart the laptop again, sometimes could work or a blue screen probably occurs its normal though

https://rog-forum.asus.com/t5/amd-600-series/drivers-amd-mediatek-wifi-bluetooth/m-p/857576 you can use the driver from that page, its the same driver that shows on MyAsus i think, i tried t but the problem still there

For me when I start gaming (Valorant or games using steams) the wifi automatically closes and disappears. Even when I go to the network driver the Media Tek Wifi Driver is in hidden. I have tried you solution but still same error occurs all the time for steam games.

Exact same issue and i tired of trying everything even reset my laptop. if you get any solution then please let me know.

Which solution helped you ? Please reply as I have the same issue ...

Idk what i did it seems that the problem is solved but not at all cuz sometimes the wifi still disappear but not while playing games anymore i can keep playing a long while without any wifi disconnection although what i remember did i download the last wifi driver in MyAsus 3.0.1.1294 version also i did some tweaks with WinAero and another external program to disable some background and processes, I uninstall and install Armoury Crate as well.

What I think I think could be the cause of the problem I guess it is the heating of the Wifi board, its kinda weird but this problem makes sense in my case this problem occurred now in summer,  what I did was keep my laptop temperatures low and another important fact I change this parameter in regedit https://youtu.be/VrPbdEnMH-A?t=163

it is not necessary to set it to disable in power settings you can use enabled and get a similar performance and good temperatures apparently when using aggressive the ghz of the cpu are unstable and increase to 4.5 or more depending on your cpu which causes higher temperatures, so you can try it and see if works

Does this cause any other issues I really don't want to mess with regedit if it returns (most of the stuff I tried like uninstalling the drivers only just caused the problem to be less frequent)

Try downloading drivers from Lenovo, I also have an Asus computer, and I downloaded drivers from Lenovo and it worked, but first delete the old drivers https://support.lenovo.com/ag/en/downloads/ds552327-mediatek-mt7921-wireless-lan-driver-for-windows-...
