How to figure out the exact driver needed for the WiFi card to install it on Linux?
I apologize if this seems like a trivial matter, but I have a laptop (a Lenovo Ideapad 3 to be exact) and I can't get WiFi (or Bluetooth) to work on anything other than Ubuntu 23.04 and its flavors. I tried OpenSUSE Leap and Debian 12, both couldn't detect the built-in WiFi card. I also tried Ubuntu-based distros such as Linux Mint, KDE Neon, and Zorin OS, same problem. I tried Kubuntu 22.04 LTS and even that couldn't detect the WiFi card! So for the mean time, I'm stuck with using Ubuntu 23.04. Any ideas to get around this? Can I use Ubuntu to figure the exact WiFi card that's being used then download its driver? If so, how can I do that exactly? Note that my Laptop doesn't have a built-in Ethernet port, and I don't want to buy a USB Ethernet adapter only for it not work out of the box either! Any help would be appreciated!

You could also check the symlinks for the device in the sysfs. The word after "drivers" below for a given network interface (eth0 below) is usually the name of the driver (cpsw below):
$ ls -l /sys/class/net/eth0/device/driver lrwxrwxrwx 1 root root 0 Aug 9 10:41 /sys/class/net/eth0/device/driver -> ../../../../bus/platform/drivers/cpswOr run
lsmodand see if anything jumps out.Either way, once you find the driver name, run
modinfoto get version and other information about specific drivers.Edit: formatting
