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:

*-network

The adapter name was found using the command lspci -knn | grep 0280:

06:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902]
    Subsystem: AzureWave Device [1a3b:6040]

but also from the control panel of Windows.

The detailed ubuntu kernel is found using uname -a:

Linux Linux 6.2.0-26-generic #26~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Jul 13 16:27:29 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

The adapter MediaTek Wi-Fi 6 MT7902LEN is not supported by linux (WiFi and bluetooth don't function on Asus Vivobook 15 in Ubuntu 23.04).

To solve the problem I bought the TP-Link TX50E network card.
