This bug also affect me. Sadly I could not tell when it happen because almost always I use already known wifi hotspots. But when it happens I recognise the following symptoms:
* The More Networks menu is empty * The VPN Connections menu also empty * Could not connect any of the wifi connection from the list The nmcli command is working, so I could connect to the VPN's if I need. The pkill nm-applet/nm-applet & is working for me (I tried it just now). When I started the nm-applet I find the following writing in the terminal (it maybe not related): sasa@mochrul:~$ nm-applet & [1] 29030 sasa@mochrul:~$ ** Message: applet now removed from the notification area ** Message: No keyring secrets found for <REMOVED>/802-11-wireless-security; asking user.
