Debian 11: Unable to detect wireless interface on an old laptop computer
I have a dual-boot OS configuration on my HDD: Debian 11 and Microsoft Windows 10.
My CPU belongs to Intel 4th generation (Haswell) and I even installed packages such as firmware-misc-nonfree firmware-iwlwifi firmware-realtek
Microsoft Windows 10 is able to detect and makes use of the wireless chipset on my computer's motherboard.
However, Debian 11 is unable to detect it (wireless chipset). I only installed the bare minimum lxqt-core and lightdm packages (no fanciful stuff).
I issued the command:
ip link show
and there is not a line that says something like wlan or wl01 etc...
Below is the output of lspci:
