Bug Description
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://
100 /var/lib/
1.0.4-0ubuntu5 0
500 http://
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.
