Title:
When closing the lid of laptop, WiFi disconnects and doesn't reconnect
afterwards
Status in network-manager package in Ubuntu:
Incomplete
Bug description:
I am getting this issue since about a year on my Lenovo Thinkpad x240
with Ubuntu Mate
I have configured the computer to stay awake and empty the screen
(system settings > power management) when I close the lid with the
power plugged in.
What I expect to happen:
Wifi network stays connected and network related programs (like bit-torrent
or http downloads) continue to run.
What actually happens:
Wifi always disconnects after closing the lid and doesn't come back upon
opening it.
I just see a "two arrows"-symbol on the top bar.
When I try to reconnect manually, the wifi symbol is blinking, but the
network manager eventually gives up.
I have to disable wifi (or network as a whole) for a second and enable it
again, to then automatically reconnect to my home wifi network.
