I have the same symptom (wifi ends up disconnected after resume, cured by running a scan manually) but I'm seeing this after upgrading to 16.04.
One oddity is that network-manager often shows that it thinks it is connected to an AP after resume but it's not the correct one. It seems to think it is connected to my neighbour's AP, for example. I wondered if the APs had swapped channels due to autodetection or something. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1332904 Title: Network manager stopped scanning for wifi networks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1332904/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
