Concerning the issue that if I unplug the ethernet cable, the Network Manager icon in the systemtray becomes red color and when I plug it again, it remains red and no connection is detected, I have just confirmed that if I tick the allow automatic negotiation mark in the Wired tab of Edit Connections in Network Manager, then now when pluging the ethernet cable again, the Network Manager icon becomes normal color again, it detects the ethernet connection and it re-connects automatically Ok.
I don't know if this option was available before, as I didn't have to choose such option in previous versions of Kubuntu, but this was not a bug but a change in the options of Network Manager (and that it's not marked such option by default). I attach you a screenshot for reference (in Spanish). ** Attachment added: "Screenshot_20180809_091556.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1771749/+attachment/5173238/+files/Screenshot_20180809_091556.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771749 Title: Ethernet connection lost after few minutes since starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1771749/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
