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

im facing kinda the same issue. The card disconnects 5mins after booting. Another issue that im facing is that even when my laptop connects to the wifi either wireless of through lan, it shows connected but no internet, but im able to browse stuff on chrome, though the windows update or the store or epic games, nvidia geforce experience wont work and show no internet connection. Please help, i have already tried resetting the wifi, reinstalling driver etc. I need serious help.

So I have tried nearly every solution written out there from updating the driver, uninstalling it, rebooting and entering BIOS but it would only work for a few minutes and then disconnects and I would have to restart the laptop.

الحل اللي انا كاتباه فوق هو اللي حل المشكلة ومبقتش تتكرر تاني لان اللي فهمته ان المشكلة في تحديث معين هو اللي بيخلي كارت ال wifi يفصل فعشان ترجع زي قبل التحديث محتاج ترجع اللابتوب لاعدادت قبل التحديث من طريقة
