How can I get my qualcom wifi adapater working on Ubuntu 20.10?

Question

Laptop is DELL XPS 17, this does not appear to be the Atheros controller frequently mentioned on this site.

I do have a RJ45 dongle that works, so I can download what is necessary.

Bleeding edge hardware and linux... :(

It just stalls. Just sitting here. Htop shows no CPU activity.

Ran again and it completed.

Rebooted and got:

error: you need to load the kernel first.

Disabled Secure boot now

But when searching for networks it doesn't show my router, which my phone sees and uses.

In addition to kernel version 5.11,you also need required firmware. Please do:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.197_all.deb sudo dpkg -i linux-firmware*.deb

reboot

SUCCESS!!!

We need more detailed information. Please edit your question to show the result of the terminal command: lspci -nnk | grep 0280 -A3 Welcome to Ask Ubuntu. — chili555, Apr 14 '21 at 20:13
Added, thanks for the quick responses. Try that with Fedora! :) — user939857, Apr 18 '21 at 14:20
You need kernel 5.10. edit: see for instance https://askubuntu.com/a/1304400/15811 — Rinzwind, Apr 18 '21 at 14:38
Thanks, I just did an apt upgrade but I am on kernel 5.8.
Suggestions? — user939857, Apr 18 '21 at 16:08
I will try this, which should bring me up to 5.11

No, it boots to kernel 5.11 but still doesn't see the router, but it sees the wifi controller. — user939857, Apr 19 '21 at 17:10

WOOHOO, I know have a usable $4k notebook. Now to get the sound working, I will make that a separate question.
Thank you very much.
