Ubuntu trigger wireless connection on host event?

[knuckleup]

Under Ubuntu or Xubuntu 14.04/ 15.10/ 16.04:

Say i have a established wireless connection that i can connect/disconnect from via "Network Manager".

Is there a script or something i can use to connect to this AP when an particular event happens?....eg When a video file is written to a particular folder on the host.

Then after a set time frame (15 minutes)disconnect from that AP.

If this can be done, please describe step-by-step?

It's going to involve programming. If you're up to doing that this should give you a sufficiently viable starting point. If you're not up to doing that, I seriously doubt people will be doing it for you.
