I know this problem has been asked many times, and I know this, because I'm searching for solutions for months, but I couldn't find any.
I'm using ubuntu 20.04. As I said, bluetooth and WiFi are missing. And I mean they're completely missing, like my laptop doesn't have those options or anything related to them. Rfkill's list command doesn't show anything. All of those comments that'll give you some information about drivers don't show anything about bluetooth or WiFi. Nothing. Zero.
I specifically searched my problem with the laptop model, it turns out that the brand of the drivers(which is Broadcom in my case) does this on purpose, so people can't use their drivers. There was a solution with lots of votes on this site, it was saying "...download exe drivers and open with with an archive manager..." and so on. I did, but couldn't find the file they were talking about. So that solution basically didn't work, it was too complicated anyway.
I believe there's an easy solution for this, but I don't know what and it annoys me very much. I didn't do anything to lose them except switching to a different OS. I was using Windows, it was pure pain to use it. Now ubuntu works fine, but I don't have WiFi and Bluetooth.
Edit: lspci -nnk | grep 0280 -A3 command showed nothing.
Edit 2: sudo lspci

Edit 3: I just checked the wireless in BIOS and it says enabled.
