nm-applet sometimes shows all networks, then none

[Ian]

I'm using Lubuntu 15.04 on an EeePC 901. Using the home wireless network is fine, but two times in two different places recently, the nm-applet has seen all the networks for a few seconds after bootup and then decided it cannot see any.

(Photos of this are available, but as I can't get scrot to capture the popup list of lots/no networks, they're via a camera.)

Based on two lines in /var/log/syslog ..

Aug 2 19:35:45 eee901 kernel: [ 23.933607] eeepc_laptop: BIOS says wireless lan is unblocked, but the pci device is absent
Aug 2 19:35:45 eee901 kernel: [ 23.933614] eeepc_laptop: skipped wireless hotplug as probably inappropriate for this model

.. very late in the start up process I wondered if the wireless card was, for some reason, being ignored from this point, but the Ubuntu Forums wireless script shows that something can still see all the networks here:

I thought I had changed the package, but dpkg reckons nm-applet is part of network-manager-gnome rather than network-manager.

After trying a number of things, deleting the bulk of ~/.config seems to have worked, so it was probably some old setting from there.
