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.
