From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to figure out the exact driver needed for the WiFi card to install it on Linux? (lemm.ee)

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!

Drivers are usually there in the kernel and usually works out of the box. You shouldn't need to manually install drivers with linux generally (except for proprietary drivers cough nvidia cough). But if your laptop is quite new, you need to have a new enough kernel. That would explain why ubuntu 23.04 works but not not 22.04. The kernel in 22.04 is probably too old to have the drivers for your network interface. Check what kernel version is shipped with ubuntu 23.04 and make sure that whatever distro you try have at least that version. Stable LTS distros often don't work on brand new hardware.

I understand that. But what's making me scratch my head is that I tried running Linux Mint 21.2 and Debian 12, both of which to my knowledge were released very recently, and yet both failed to detect my WiFi card. Are they running an older linux kernel?

Yeah they’re running an LTS kernel. Debian 12 is on 6.1 when we’re on about 6.48. I’m not sure about Linux Mint, but I know it uses LTS too so it must be 6.1 or older. Not sure if upgrading the kernel would help you, but just throwing that out there.

Mint is based om LTS ubuntu, so same as 22.04.
