Public bug reported:

Twice today, NM 1.1.93 has dropped my wifi connection.  I don't know why
and haven't looked; the connection is usually stable since the AP is in
the room with my laptop, but perhaps there's something up with the
kernel I'm currently running.

However, the serious bug that I'm reporting is that when the wifi
connection dropped, nothing told me that this had happened.  nm-applet's
display did not update; there was no automatic reconnect attempt; even
the VPN process, which was no longer operational because it had lost its
route to the VPN endpoint, was still running (and the lock icon still
shown on nm-applet).

Only when I looked at my routing table to see what was going on did the
problem become apparent.

Since this has already happened twice today, I can probably get more
debugging information "soon" if needed - just ask.
