Sorry, I'm sure you get WiFi questions fairly often and I've looked through a good amount of them but each one starts with running code in the terminal to see which firmware you need for your computer. But when I run "lspci | grep Network" or "lspci -nn | grep Network" literally nothing pops up and it just sends me to the next line in the terminal. Any help would be greatly appreciated because my laptop won't boot from a live usb, so I'm pretty much stuck with Sparky. So if I can't get WiFi working then I am basically going to have to get a new laptop.
1. Do you have an ethernet cable and a connection on your laptop?
2. try just "lspci" (note the " " are to highlight the text needed. Pick out the appropriate output and post.
3. The previous comment appears directed for Windows installations, I would not use.
4. I can't say how much of a fan of inxi I am. If you wish "sudo apt install inxi" after plugging in the ethernet
4.1 Post output of "inxi -bxr"
