Title:
Wi-Fi networks list is empty after resume from suspend
Status in linux package in Ubuntu:
New
Status in network-manager package in Ubuntu:
New
Bug description:
After the laptop has resumed from suspend, there are no Wi-Fi networks
listed in the network manager applet. The connection still works but
the applet shows the Ethernet connection icon.
Steps to reproduce:
1) close the laptop lid to enter suspend (or click "suspend" in the system
menu in the upper panel)
2) re-open the laptop lid, resuming the laptop from suspend, unlock the screen
3) check the network manager applet, no Wi-Fi networks are listed, disabling
and re-enabling Wi-Fi doesn't help
This is a problem because it isn't possible to connect to another Wi-
Fi network.
The problem disappears if i run:
sudo systemctl restart network-manager.service
as described here: https://askubuntu.com/a/761220, however, the
systemd unit file solution suggested in the same answer doesn't work,
probably due to a timing issue (the command is run too early and the
Wi-Fi card is not ready).
