[Touch-packages] [Bug 1635907] Re: Can't connect to Wifi network after suspend and resume
Note, in the kern.log above which shows the last hour of usage, there is a Call Trace for NetworkManager from the previous time I booted up after I was no longer able to reconnect. It's probably worth looking at this crash, however, in the most recent reboot, a restart of NetworkManager did bring back the wifi network after a resume. -- 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/1635907 Title: Can't connect to Wifi network after suspend and resume Status in network-manager package in Ubuntu: New Bug description: Beginning in Ubuntu 16.04 and getting worse after upgrading to 16.10, I can't connect to wifi networks after suspending and resuming my laptop.
