Two weeks ago I installed Ubuntu 18.04 for the first time. I have a wired internet connection there.
Most of the time, connection works good but sometimes, 2 or 3 times a day, I suddenly have no internet connection. I need to turn the wired connection OFF and then ON to fix this.
Can't figure out where is the problem. The cable is OK and connection works on other devices in the network.
I have automatically installed drivers.
Do you know what can I do?
