Anytime the comms light is red, but i think it should be green, I first switch to the second tab of the DS to look at the ping results. If the robot light is green, then the DS knows the IP of the robot -- it can ping the robot based on what you put into the team tab of the third tab.

If the robot ping light is green, that means ping works, but the UDP protocol doesn't. This is either due to firewall or other port blocking mechanisms or the roboRIO protocol program is no longer running. I will sometimes hit the reset button on the roboRIO to get the program running, though if you were shelled in, you could do other things to check on it and get it going.

If the ping light is not on, click to the third tab to see that the team number is entered correctly. You can click on the arrow next to the field to see if the robot shows up, but it probably would have been selected if it were. You can hold shift and click the arrow to see an unfiltered list. Due to the radio change, you may want to look at the link light on the roboRIO. The small green and yellow LEDs right next to the ethernet port. If not on, unplug and replug the cable, make sure it is seated on both ends. Also swap the port used on the OpenMesh, though the port next to the power should be preferred, it is quick to try both.

It is possible to debug further to see if it is truly an mDNS issue, but personally I haven't seen that many occurrences this year compared to last.

If you have other observations or symptoms, please post them.
