Watch the lights: the big orange Robot Signal Light, the ones on the D-Link router, the ones on the cRIO. They'll give you good clues as to what is going on with the robot when you lose control.

Your symptoms are starting to point more clearly to a power issue. One of the common problems teams have is connecting the robot radio incorrectly. Can you describe exactly how the D-Link is being powered? Specifically, where is it connected to the Power Distribution board, and what else is connected to its power input?
