I experienced the same problem (wired AND wireless both down) on KDE Neon 18.04
Tried several things - plug in a LAN cable - restart network service - 2 reboots - checked that my router was not down (I had internet access on my cell phone wifi) The laptop is dual boot W10-KDE Neon Booting W10 --> I have network connection again. Boot KDE Neon again --> network wifi and Ethernet works again Unfortunately I cannot provide debug/error msgs as the problem was quickly solved by booting W10 and up to now it has not occured anymore. The only info I can provide is that it happened a few hours after doing updates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1666432 Title: Internet drops every few minutes on wired and wireless connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1666432/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
