Asus TUF F15 stubbornly "No Wi-Fi Adapter Found"

Trying to get Ubuntu started on an Asus TUF F15 laptop... I've been reading what feels like hundreds of webpages and SE questions and none of the solutions I have read has worked despite seeming to be the exact same situation!

I've installed 20 LTS and 21 as well as Linux Mint. Nothing's worked!

I'm not well-versed in drivers et cetera so I'm extra confused and in the dark. If anybody could at least help me figure out what the issue is... is there some established bug report my hours of Googling hasn't got me to, or is something WIP, or...

Any help or at least explanation would be appreciated.

Asked command outputs:

$ lsb_release -d
Description:    Ubuntu 21.04

$ lspci -nnk | grep 0280 -A3

Solution 1:

Following two links from @chilli555's comment got me the solution for this case!! Hopefully if you happen to be in this situation and nothing else has worked this will be the one.

It's installing an updated kernel.

wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12.5/amd64/linux-headers-5.12.5-051205-generic_5.12.5-051205.202105190541_amd64.deb

wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12.5/amd64/linux-headers-5.12.5-051205_5.12.5-051205.202105190541_all.deb

wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12.5/amd64/linux-image-unsigned-5.12.5-051205-generic_5.12.5-051205.202105190541_amd64.deb

wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.12.5/amd64/linux-modules-5.12.5-051205-generic_5.12.5-051205.202105190541_amd64.deb

sudo dpkg -i linux*.deb

This downloads a bunch of packages and then installs all of them at once. Thanks again to @chilli555.
