Title:
Network Manager fails to reconnect to wifi after resuming from suspend
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
After resuming from suspend on my laptop, I have wifi enabled, but
Network Manager does not automatically reconnect, and it's list of
available wifi networks is blank.
If I run `sudo service network-manager restart`, then this fixes
everything and it automatically detects and connects to my wifi
hotspot, but this shouldn't be necessary.
This problem seems specific to 16.04. Under 14.04, NM worked
perfectly. After I upgraded my 14.04 install to 16.04 it started
happening, however, I assumed this was likely due to some broken
config file leftover from the upgrade. However, I recently did a fresh
install to the same laptop on a blank hard drive, and the problem
still exists.
