Public bug reported: 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).
