Re: Upgraded to ubuntu 17.04 and lost my wired connection

[Jarvis Carlos <carlos jarvis7 gmail com>]

Thank you very much, Francesco.  With your info, I blanked the content of file "/usr/lib/NetworkManager/conf.d/10-globally-managed-devices.conf" and my wired connection came back!

My summary:

1. The code dealing with 10-globally-managed-devices.conf may have somewhat wrong parsing.

2. If I swap the order of wifi and wwan in "[keyfile] unmanaged-devices=*,except:type:wifi,except:type:wwan", then it's wifi that doesn't work.

3. The network info/control of ubuntu unity doesn't have good sync with NetworkManager. Try the point 2.

best regards,

jarvis

Hi Jarvis,
 seems NetworkManager does not manage your ethernet devices.
Conf snippet just above allows NetworkManager to manage just wifi and
wwan devices.
