cRIO's Ethernet Port Randomly Disconnecting?
We took apart all the electronics from our 2009 robot (which still works fine), and re-wired everything up to a bare chassis with nothing but 2 motors and camera for testing the new Classmate PC and related software.

However, we can't get the Classmate or any other computer to connect to the cRIO. It doesn't lose power, but ethernet connection seems to randomly turn on and off every few seconds. The LEDs on the ethernet port turn off for a second when this happens.

We're 99.9% sure we wired everything correctly. We already tried different cables and computers. We tried a direct wired tether from the PC to the cRIO. We made sure we were using a freshly recharged battery. The cRIO Reset/Format tool does not function as we can't establish a connection long enough to reset it.

Anybody know what's going on, or how to fix it?
