I recently switched to Ubuntu 22.04. Before that, I used Windows 10. I had to buy a new ethernet card (TP-Link TG-3468) because my mainboard's ethernet port stopped working. With the ethernet card, ethernet kept disconnecting. After some googling, I disabled "Energy Efficient Ethernet" on Windows. This screenshot does not depict Windows 10, but it looks the same way. I now have the same issue on Ubuntu, and I wanted to ask where I can disable the same setting for my ethernet card but on Ubuntu 22.04

You can disable Energy Efficient Ethernet in kernel parameters.

Run

sudo nano /etc/default/grub

and change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash igb.EEE=0"

Save the file and run

sudo update-grub

Note: This setting doesn't work for you because you have a wrong first line of /etc/default/grub. You accidentally removed # from the beginning.

If you change this file, run 'update-grub' afterwards to update

should be

# If you change this file, run 'update-grub' afterwards to update

That should disable the feature after a reboot.

You can check the status by

ethtool --show-eee enp6s0

You can also disable EEE using ethtool, but it won't stay after a reboot.

ethtool --set-eee enp6s0 eee off

I believe that the alternate driver for your device, r8168, has eee_enable as a manipulable parameter. Let’s install it and see if it helps.

sudo -i
apt update
apt install -y r8168-dkms
echo “options r8168 eee_enable=0”  >  /etc/modprobe.d/r8168.conf
exit

Reboot. Is there any improvement?
