Once again, I'd like to kindly remind people the problem is most likely not the NI C-RIO. The C-RIO's job is to process the information given to it from the sensors and inputs from the radio and use that to control the various aspects of the robot.

The problem most likely is the radio. The C-RIO does not connect to the driver station at all. It's the D-link radio that does.

The C-RIO was introduced 4 years ago in 2009 to help in handling the vision processing that was introduced more heavily in 2009 than any other game, and to accommodate for the old IFI technology. The radio, on the other hand, wasn't chosen too well, and as a result left many teams without connectivity to the field.

tl;dr: It's most likely the radio's fault, not the C-RIO's.


EDIT: I am making these accusations because while it certainly is possible it is something else, multiple robots in every match had comms issues. Some of the teams never had comms issues before. I don't have a field diagnosis, but this is my result from troubleshooting the problem with what I have.
