Driver station has no robot communication

[johnhenry]

we are not a rookie team, but we have been out of completion for a couple of years. We started out with a brand new control system this year. We have upgraded firmware and imaged the PDM, roboRIO, PCM, and the radio. After wiring everything up all system status lights appear as they should be. We created a test program via Robot Builder and downloaded that to the roboRIO successfully. When we start the Driver Station with an Ethernet tether we get NO ROBOT COMMUNICATION message. We can ping the robot via Ethernet and USB cables. We can get into the Web Dashboard of the roboRIO via USB and all addresses appear correctly.

What are we missing???
