Public bug reported: My network cable is plugged in but NM shows it is trying to connect to WiFi. This happened on Ubuntu 15.04 and continues after upgrade to 15.10. I have a RTL8723be card and it is hardly working correctly, but that is a whole other issue.
1) Ubuntu 15.10, 64bit 2) network-manager: Installed: 1.0.4-0ubuntu5.1 Candidate: 1.0.4-0ubuntu5.1 Version table: *** 1.0.4-0ubuntu5.1 0 500 http://mirrors.neterra.net/ubuntu/ wily-updates/main amd64 Packages 100 /var/lib/dpkg/status 1.0.4-0ubuntu5 0 500 http://mirrors.neterra.net/ubuntu/ wily/main amd64 Packages 3, 4) Expected is that when network cable is plugged in and obviously I have a stable, well running connection, NM should not try to also connect via WiFi. Also expected that when I pull out the cable, the WiFi would connect. Instead the wifi shows connected but there is no internet activity.
