My pc does not detect wifi networks. After a fresh install of Linux Ubuntu on a new machine, the computer is not able to detect any wifi networks. I checked the manufacturer's website for wifi drivers, but they are only available for Windows.
My setup is dual-boot. It has two solid state disks ADATA SSD 512GB LEGEND 840 M.2 PCIE M.2 2280. Windows 11 is installed on the first disk and Ubuntu Desktop 22.04.3 LTS on the other. The motherboard is ASUS TUF GAMING A620-PRO WIFI. The wifi adapter name is MediaTek Wi-Fi 6 MT7902LEN Wireless LAN Card. Ubuntu kernel is 6.2.0.26-generic.
Ubuntu seems to be able to recognize the device. When I run sudo lshw -C network I get:

but also from the control panel of Windows.
