Hello Promox Community,

i have 4x Dell Optiplex 3000 Thin Client with Intel Silver n6005.

On Proxmox 7.4 and 8 is the network performance terrible, maybe ~ 500KB/s, with Proxmox 8 lose the server after 5 or 10 mins the network connection.
With Proxmox 7 it´s a little bit more stable, but the network performance is bad.
Im running on Proxmox 7 now.

Code: 
lspci -v
       01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)

        Capabilities: [178] L1 PM Substates
        Kernel driver in use: r8169
        Kernel modules: r8169

I am a little bit confused, lspci show me "Realtek Semiconductor Co., Ltd. RTL8111/8168/8411", but the kernel driver is r8169?

Tried this from SQLJames/proxmox-realtek.md (https://gist.github.com/SQLJames/fe6fcd5e819d864986ce2eff6ad350da) on github, but is not working on me :(

Has anyone an idea or tutorial for me?

Regards,
Chris

Hi,
there are known issues with the r8169 driver, which seem to be related to power saving features. You might install the dkms-r8168 driver as a workaround on PVE 8, see also https://forum.proxmox.com/threads/networking-issues-pve8.129742/

I installed all 4 Dell Optiplex 3000 with proxmox 8.0.4 new.

- change the /etc/apt/sources.list
Code: 
deb http://ftp.de.debian.org/debian bookworm main contrib non-free non-free-firmware
deb http://ftp.de.debian.org/debian bookworm-updates main contrib non-free non-free-firmware

# security updates
deb http://security.debian.org bookworm-security main contrib
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

- apt update
- upgrade over webinterface "> _Upgrade"
1695991020754.png
- reboot
- apt install pve-headers -y
1695991154086.png
- reboot
- check kernel driver ....
1695991295335.png
- apt install r8168-dkms -y
- check the new driver is installed

- blacklist r8169
Code: 
echo blacklist r8169 >> /etc/modprobe.d/blacklist-r8169.conf

- update grub
Code: 
sudo sed -i 's/GRUB_CMDLINE_LINUX=""/GRUB_CMDLINE_LINUX="r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off loglevel=3"/' /etc/default/grub
- proxmox-boot-tool refresh


After restart, looks good, but 5 or 10 mins later crash the network

Please try the latest 6.5 based PVE Kernel without the dkms module installed.

Hello!

I am also struggling with the lan driver problem you mentioned.
I have an OptiPlex 3000 Tower machine.
Did the solution you mentioned completely solve your lan problem (lan crash)?

In another forum post, they mentioned turning off the C-State control in the bios, but I don't want that.
