Before reflashing things, I'd try other network options and see if that is the root of the problem.

First, I'd connect roboRIO and computer via USB cable and see if the deploy behaves the same or better. Then try ethernet, and then try wifi. The deploy code may not like having lots of interruptions or having to restart the connection mid-deploy, and this may happen sometimes, especially with wifi in a school environment.
