Hi all,
I know that proxomx is not big fan of wifi connections, but I would like to enable the wifi card on my pc.
At the moment it is seen by the system but it seems not working :-(

A the moment I'm running on a PM 8.3.5

Here are some infos:

# uname -a

and untill here it seems everything is working, but if I try to use the device it seems not working :-(

# iwconfig
lo no wireless extensions.
enp3s0 no wireless extensions.
enp4s0 no wireless extensions.
wlp2s0f0 no wireless extensions.
vmbr0 no wireless extensions.
veth101i0 no wireless extensions.
veth105i0 no wireless extensions.
veth104i0 no wireless extensions.
# iwlist wlan0 scan
wlan0 Interface doesn't support scanning.

Have you any idea what can I try to make it work?
 
Have you installed firmware-iwlwifi package?

ETA: On the other hand, this card must be very new as it claims to be wifi 7. You might have to get the firmware from kernel.org or Intel. It almost certainly isn't in the Debian stable packages.

I should also add that the recommendation from Proxmox is to not use wifi as your primary interface. The reason is that you generally can't bridge wifi. See the relevant chapter in the PVE manual, which is linked at the top right of the PVE main screen.
https://pve.proxmox.com/wiki/WLAN

Here are the instructions for setting up wifi on Debian, which also applies to PVE.

There is no way to install it without touching proxmox-ve package?

As I've wrote in the beginning on my post, I know that proxmox is not a wifi fan.
This is not the mail NIC connection, but I would like to see if I can make it work anyway
 
I was not able to log in to my PVE earlier. Now I can it it appears that the pve-firmware package is installed by default and conflicts with the Debian ones. I didn't realize that.

In looking at your initial post, it looks like it is loading some firmware. Maybe too old? Not sure. You can get the latest firmware from the link below and install it manually if you want to try that. The tree structure of the gitlab link is the same as what's under /lib/firmware on your system with the iwlwif stuff being at the top level. Don't forget make backups! It is easy to break things doing this. You will probably want to do some research to find out what files you need for the card you have.

Also, it is not that PVE "isn't a wifi fan", it is that most access points simply won't accept frames from bridged VM's, regardless of what OS is in use. So you have to either set up a routed network or only use the wifi for management.
 
Besides firmware, wifi 7 is very, very, new. As in only a few months old. It could be that the iwlwifi driver in the PVE kernel doesn't support it yet. I have a Framework laptop and someone on their forum got a Qualcom card working with kernel 6.12, but 6.11 is the newest PVE kernel last I checked.

This information isn't quite right. I've been running my Proxmox server entirely on a WiFi connection for the last three years. It hosts a large number of LXCs and VMs, and I've kept the connection current by progressively upgrading from WiFi 5 to WiFi 6, and most recently to WiFi 7.

I have never used the LAN Ethernet before.

I used this information to set up, and it is very helpful. https://forum.proxmox.com/threads/howto-proxmox-ve-8-1-2-wifi-w-snat.142831/

Here is my current dmesg information.

Don't use WiFi at all.

I build a Nat Router on Debian12 with my raspberry pi 4 2 gb.
Witch connect to my VDSL Router over Wifi 6 and local i have a 1 GBit/s privat network, i.g. 192.168.0.0/24.
The raspberry pi 4 is my default gateway for the net: 192.168.0.0/24 and can route all traffic with a iptables -t nat rule to the "world".
On the 1 GBit/s raspberry pi 4 interface, i put a tiny 5 port 1 GBit/s switch, so all Proxmox VE Server work as i want.
