[Bug 1480972] Re: nm-applet sometimes shows all networks, then none

 

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

Title:
  nm-applet sometimes shows all networks, then none

Status in network-manager package in Ubuntu:
  New

Bug description:
  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:
