i tried removing all network connections, both wifi and cable and after a reboot
wifi icon showed as the cable connection (arrows up & down)

editing the wifi connection==>ipv6 set to ignore + a reboot got my wifi icon back

i had the bug again this morning on boot so ipv6 to ignore did not fix the dhcpdiscover loops
network-manager restart solves it temporary

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

thanks

upstream comment suggests it should be fixed with the current SRU, can you try that?

https://bugs.launchpad.net/ubuntu/+source/network-manager/1.2.0-0ubuntu0.16.04.2

[lotuspsychje (lotuspsychje)]

Sorry, why should the average user compile a higher network-manager version when the cause of the issue is known? 16.10 has network-manager Version 1.2.2-0ubuntu1 (yakkety), so why cant 16.04 get a patched network-manager in updates?

[Sebastien Bacher (seb128)]

Did you see the url I gave? It's a SRU for 16.04, it's going to be copied to updates once verified but you can enable xenial-proposed in the software properties settings and install it if you want to test it before it's migrated to updates

[lotuspsychje (lotuspsychje)]

Ok, then ill wait till it gets verified and migrated to updates

Tnx for the follow up
