I was guessing wired, because the switch capability of the DLink comes up pretty quick, like in three seconds. Powering up the wireless takes much longer. Can you wiggle the ethernet cable between the DLink and the cRIO and see if you can cause the situation? Also do the bend and flex of the cable to see if it has been nicked or has an internal break.

You may also consider replacing the cable and repeating the previous test.

The message basically says that the DS lost connection to the robot. That happens each time you power down the robot, for instance. So things that cause the communication to drop out for 5-10 seconds are what you are looking for.
