Dell Latitude e6400 on Ubuntu 14.04 not working after resume from suspend

Question

After resume from suspend, my Dell Latitude E6400 is not working and I get a message like saying wifi connection is offline and the system is unavailable. As a result I have to reboot the system.

Is there a way to troubleshoot the issue or apply a fix?

Detail regarding network interface:

Finally I've fixed the issue by installing proprietary NVIDIA driver. Just had to select from

System Setings > Software & Updates > Additional Drivers > Use NVIDIA binary driver - version 331.38 from nvidia-331 (proprietary, tested)

So, resume from suspend on my DELL E6400 is working as expected.
