I see something similar. Looks like in some cases it is enough to issue
a
sudo iwlist wlan0 scan
to make nm show the available connections again.

Title:
nm-applet not showing existing wifi connection
Status in network-manager-applet package in Ubuntu:
Incomplete
Bug description:
Frequently, not always, the wifi connection and the existing wifi
networks don't show up on nm-applet. Still, the default network
connection is established in the background. But nm-applet does not
allow connection management.
In the picture: nm-applet shows no connections/netowrks but in the
connection information dialog you can confirm that the wifi connection
was established
