VMWare appears not to be the cause. Starting the PC this morning from cold NetworkManager has consistently failed to connect to WiFi - in fact I have had to connect a wired connection to get any network connectivity. The workaround described above of restarting NetworkManager(Dispatcher) hasn't solved it. Tried restarting wpasupplicant too but that didn't help.
I noticed from the log files that avahi would get report the correct WiFi DHCP lease being assigned and then immediately drop it because NetworkManager had failed.
