Dear community,

I'm stuck getting Proxmox running on my N100 mini-pc.
The graphical installation of 8.1-2 only detects the wifi card, not the two ethernet devices. I tried to get an internet connection with the wifi installation (tried static IP and dhcp) but this also didn't worked for me.

lspci -v show the following:

Code:

It looks like there is no "kernel driver in use", unlike the other devices that are listed.

ip a looks like this:

Code: 
1: 10: <LOOPBACK, UP, LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default glen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6:: 1/128 scope host noprefixroute
valid_lft forever preferred_lft forever

2: wlo1: <NO-CARRIER, BROADCAST, MULTICAST, UP> mtu 1500 qdisc noqueue state DOWN group default glen 1000
link/ether 70:cd:0d:89:69:12 brd ff ff ff:ff:ff:ff
altname wlp0s20f3
inet 192.168.1.200/24 scope global wlo1
valid_lft. forever preferred_lft forever

How do I get the ethernet driver on the computer without internet? Is it possible to add a driver to the bootable USB stick, which I created from the image?

Thanks alot!

Oh, you're right, this looks very similar. Hope we find a solution for it.

So after some research, I think Im gonna buy a usb to ethernet adapter and connect to the internet that way. Then install the R8168 drivers and return the adapter. I believe that will work, if anyone knows more on this topic and can direct us that would be great.

I'm trying to get my wifi to work so I can download the required r8168 drivers. But I just can't get it configured. Could someone please give me a snippet of the /etc/network/interfaces file that I can use to get my wifi running without NAT and without vmbr0?

No matter what I try, I can't get a ping on my gateway 192.168.1.2

Thanks alot!

Maybe have a look at the Wiki: https://pve.proxmox.com/wiki/WLAN Or search the forum: https://forum.proxmox.com/threads/using-wifi-instead-of-ethernet.56691/

It's not clear to me what you tried and/or already setup properly, sorry.
 
I got my wifi running now by installing "wpasupplicant" and it's dependencies from a mounted usb stick.

Installed new Linux Kernel 6.8 // no difference, network devices still hasn't the driver in use
Installing r8168-dkms_8.052.01-1_all.deb // didn't help either.

Any suggestions?

Ok, i think i figured out what is happening

demsg | grep8169

r8169 9999:01:00.0: error - ENODEV: unknown chip XID 6c0, contact r8169 maintainers (see MAINTAINERS file)

Google for 6c0 shows a kernel mailinglst, error is pretty new and will be fixed in kernel 6.10

Have you tried the new driver? 8.053.00

If you succeed please tell me how you did it?
Also how did you get access to wifi. No matter what I try I cannot. You mentioned wpa supplicant. How to use that. Sorry I’m a newbie.
