After install the Ethernet worked great, but after some reboots the ethernet connection is lost and i can’t even detect the ethernet card anymore.
sudo lshw -C network, only WIFI is detected, no Ethernet (enx…).
This problem is known with Realtek 8152 or 8153 USB-C Ethernet cards.
A fix was to stop TLP to send certain USB devices to auto-suspend, because they won’t wake anymore.
Ethernet Realtek 8153 (Dell WD15 Dock fix)
sudo gedit /etc/default/tlp
add this lines to the file:
Save & reboot.
This usually worked.
According to the new Ubuntu Budgie version changelog it does not have TLP installed anymore, because of many bugs.
But the Ethernet card is gone again.
