When setting it up from work, is the device you are running the app on also connected via WiFi to that router?
Are there any firewall settings or ports/services being blocked? The camera needs Internet connectivity to communicate with the mydlink servers to setup.
On the app during setup, where does it fail? It will go through wireless setup, and then binding. If it fails during WiFi setup, in most cases the WiFi password is wrong. Make sure you type it exactly (case-sensitive). Also are there any special characters or spaces used in the password (+@#$%^) etc?
What is the EXACT error message?
Does the LED on the camera ever turn green?
