I think I too suffer from this, and that it has not been solved, when I resume from suspend I cannot see any wireless networks in the applet, and un-ticking then ticking 'Enable Networking' doesn't seem to help. Also, when I run sudo /etc/init.d/NetworkManager restart, I get the message sudo: /etc/init.d/NetworkManager: command not found.
