I'm having this problem on Lenovo G410 with the latest release 16.04
fully updated as of July 22, 2016. After coming back from suspend, the
wireless icon disappears and is replaced by the ethernet connection
icon. Although the wifi stays connected to it's last remembered
connection, the list of wireless networks also disappears from network-
manager.

Title:
WiFi fails to resume after suspend; Race with wpasupplicant / wpa_cli
resume?
Status in network-manager package in Ubuntu:
Confirmed
Status in wpasupplicant package in Ubuntu:
Confirmed
Bug description:
Hi,
I'm constantly having issues where my WiFi connection doesn't re-
establish after resuming from suspend. I think it may be a race where
the interface isn't ready yet and systemd-sleep calls /lib/systemd
/system-sleep/wpasupplicant (which is a wrapper to wpa_cli).
I normally restart NetworkManager but then found that calling 'wpa_cli
resume' works also.
Here's the logs:
