I believe we had a similar issue at the Suffield Shakedown this Saturday. If you were watching the webcast, this was the root cause of our bot delaying a few matches.

When the main breaker is closed we observe no link light on the roborio Ethernet port.
Pressing the reset button on the Rio after the radio has finished booting has worked every time for us.

I believe FRC177 also had the same problem at Suffield and arrived at the same procedure to address the comm problem.

In preparation for Shakedown we went through all software revisions and realized we had an outdated FPGA image on the Rio on our comp bot. We reimaged, and flashed the Rio prior to packing up. The reason I mention this is that prior to flashing the latest firmware, we didn't have any of the previously mentioned comm problems. Now with all updates installed we are having issues. That said, there were quite a few other teams who were not having any problems. As far as I know 177 and us were the only ones experiencing this issue at Suffield.

I haven't had a chance to look at the robot since Suffield, Ill look at the RT startup app setting mentioned. We have two other roboRios that dont exgibit this problem, but I havnt double checked the revisions of software they are running. Might end up doing a clean flash/image. I'll report back with any findings.
