Trouble connecting to WiFi with Intel 9560 interface

[Peabnuts123]

Howdy all. I've recently built a new server and would love to set up Proxmox on it. However, I seem to be running into the classic Linux problem that my hardware is too new for the system to work properly. I'm having a really hard time getting wireless to work. My motherboard is a Micro ATX Z390 Aorus Pro Wifi and the wireless chip on it is an Intel 9560 (the latest at the time of writing, AFAIK). FWIW an ethernet connection works perfectly but a wired setup is out of the question for me.
FWIW I'm intermediately experienced at using Linux. I've tried various configurations in `/etc/network/interfaces` and installing `wpasupplicant`, `wireless-tools` etc but faced a myriad of issues. In a last ditch effort I've installed `network-manager` and (using CLI but also using nmtui on a fresh install) I get what seems to be a "correct config" that crashes / errors / doesn't work. When I try to connect or bring up the wireless adaptor I get the same exact messages as the person in this post: -snip- I can't post this link because I'm new. See bottom of this post (1)

I've also seen this doing stuff manually by hand through other means (ifup, wpa_supplicant, etc.), which makes me feel like all of these common scenarios are "correct config" (but something else is still wrong).
I have also tried installing Proxmox on top of Debian (stretch). On Debian, network manager was completely able to connect to the wifi (after installing latest `firmware-iwlwifi` from non-free) and Proxmox installed okay on top of that. However, with that setup, I'm facing constant issues that seem to boil down to "Proxmox isn't quite in a comfortable configuration" (e.g. AppArmor doesn't start which keeps my LXC containers from starting, etc.) which leads me to believe the best way to setup and run Proxmox is by itself. I've tried installing `firmware-iwlwifi` over the top of Proxmox itself (forcing a conflict with `pve-firmware`) but it didn't seem to change anything. My wireless interface does show up and interact okay on Proxmox so the drivers are obviously working ~somewhat.
Anyway, this working setup on Debian means that some-way… SOME-how… my wireless NIC can be configured to run on Linux / Debian, but I can't seem to figure it out through Proxmox vanilla. Does anybody have any insight into how to diagnose/resolve this issue?

Hi,

firmware-iwlwifi

this package will be removed if you install proxmox-ve because it conflicts with the pve-firmware package.
This step is easy to download the package firmware-iwlwifi and extract it and copy it in the target dir.

Note the most wireless nic do not support bridgemode so you can't run a bridge on it and you have to use a routed/nated setup.

Hey wolfgang I appreciate the reply.
As I said in my original post I tried force-installing the `firmware-iwlwifi` package as a proof of concept but it didn’t really affect anything.

I had trouble connecting internet... Thanks wolfgang it worked for me. It looks like its not working for all. Firmware-iwlwfi package is working on some selected devices. If firmware-iwiwfi package is not working on your device then 192.168.1.7 IP Panel might be helpful.

Peabnuts, did you end up finding a solution to this?

So after downloading the firmware and extracting what exactly do I move? From another thread I gather I extract the firmware, then extract the data.tar and move all the ucode files from the newly created lib/firmware extracted from the data.tar file to the actual lib/firmware directory. I tried this and haven't had any luck.
