06:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter

I tried Hot to install mediatek ... but after reboot, nothing change. I don't understand why I have drivers for mt7921e neither.

I saw some thread for ASUS laptops with similar problems, but I don't clearly understand them.

Hope, someone can help.

Driver Status: mt7921e is active
Driver Activation Cmd: "modprobe mt7921e"

It says driver is active. Did you try the driver activation command?

> 5.7 GHz is restricted or prohibited outside north america and china.
The EU limits it to 0.025W for short range devices only.

Yes, I did. I am connected to internet but I can not see the networks with >5ghz.

The funny thing is that during the installation, the ISO was working with 5ghz networks
