It could be something I have seen as well.

NetworkManager seem to have been extented to understand suspend/resume cycles 
but sometimes gets it wrong and doesn't get the resume.

In such cases you can try to explicitly tell to "wake" like this:

qdbus --system org.freedesktop.NetworkManager \
    /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.wake

Cheers,
Kevin
