[Q] How does android determine if it has internet connectivity - Android Q&A, Help & Troubleshooting

Question is as exactly as it is in the title; how does Android come to the conclusion that it has complete internet connectivity (or connection to google services), and consequently will turn the signal bars blue (on stock android devices).
I am trying to fix a problem at work where if I put my phone on the company wifi, my phone never seems to think it has internet connectivity, even though I do. The consequence is most apps don't attempt to pull new data, and therefor never notify me of new messages. This includes gmail, google voice, and hangouts.
I don't have direct control of the network infrastructure at the moment, so right now it is easier to know what address or IP it tries to get to, and how (ping?), so it can be unblocked by the firewall or web filter.

Does really no one know? Perhaps a point in the right direction?

check your settings>wireless & Networks> WIFI>check Network notification this will inform you when there are other open wifi networks present > you need to connect to that network with password or scroll down to add WIFI network (you can add any network when you know its SSID and security used.
if you unchecked network notifications, you will " NOT" know or use of any new networks other than what you have used before.

I'm not having any issues finding or connecting to wifi, the problem is at my buisness when on wifi, android does not detect an internet connection; so it thinks I just have local network access, so most apps do not auto refresh in the background.
