Public bug reported: When doing a fresh install of Ubuntu 17.10 I notice that the installer didn't detect my wired ethernet correctly. I went through with the installation and I could still not connect to the internet. In the network settings I found that the MAC address was incorrect. It was set to ED:0B:00:00:E0:00 which is not the correct MAC address. My previous installation of Ubuntu 16.04 could find the correct MAC address automatically.
I tried setting the correct MAC address in the network settings but that made the wired connection disappear from the network settings altogether. My work around is to run the following commands at boot time: ip link set dev enp6s0 address xx:xx:xx:xx:xx:xx ip link set dev enp6s0 up (xx:xx:xx:xx:xx:xx is my correct MAC address) ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: network-manager 1.8.4-1ubuntu3 ProcVersionSignature: Ubuntu 4.13.0-21.24-generic 4.13.13 Uname: Linux 4.13.0-21-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.6 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Jan 1 15:13:43 2018 IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback InstallationDate: Installed on 2018-01-01 (0 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Release amd64 (20171018) IpRoute: default via 192.168.1.1 dev enp6s0 proto static metric 100 169.254.0.0/16 dev enp6s0 scope link metric 1000 192.168.1.0/24 dev enp6s0 proto kernel scope link src 192.168.1.105 metric 100 IwConfig: lo no wireless extensions. enp6s0 no wireless extensions.
