There are so many open bugs on network-manager, wifi and resume that it's difficult to find the right one to comment on. Anyway, trying e.g. this one. Can the people having this problem comment on whether there is Docker installed on their system?
I am specifically asking this question because a colleague of mine claimed not have any problems with WiFi in Ubuntu but since he installed Docker, the WiFi became so unusable that he was forced to use wired connection. On my system network manager never worked good (being it 14.04 or 16.04) but I cannot comment on Docker as it was installed from the very beginning. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1390709 Title: Wifi doesn't reconnect after waking from sleep Status in network-manager package in Ubuntu: Confirmed Bug description: Upgraded from 14.04 to 14.10.
