As FTAA in Buckeye, we had this problem with another team, also using Java. It absolutely baffled everyone on the field, as we had them apply the firmware update again, re-image the rio, swap radios, etc. In the end, the most simple fix was this - put the ethernet cable into the other port in the radio. I'm guessing it is in the port furthest away from the power connector. Once we made the switch to the port closest the connector, it worked the first time every time.

It cost us several hours and most of our hair being pulled out, but the issue went away completely after the switch.
