Hi everyone, I have some issues with my wifi and maybe you have some idea how I could solve it.
I have Lenovo Legion 5 with MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter. It usually works ok, but occasionally, it disconnects me from the internet. It happened on f38 when I got the laptop some months ago, and now on f39. I believe it happens when downloading at full speed after some time, but now it is occurring more often with the latest kernel update even with normal usage.
6.6.12-200.fc39.x86_64
In gnome, it shows the wifi is still connected, but with no internet (question mark on the icon) and it is not showing / canβt scan any wifi networks.
Here is lspci info:

I saw when it happens, the link is DOWN or sometimes it says group dormant instead of default.
Please let me know if you have some way for me to fix this, or any idea why is it happening. Thank you
