Firstly, have you updated driver station? When you open driver station, the name of the window should be 16.0.1 or something like that.

Secondly, have you tried connecting the RoboRIO to your driver station with ethernet, skipping over the router? If you can't connect this way, then there is probably something wrong with the ethernet port, or even the RoboRIO itself.

Worst comes to worst, just reinstall all FRC software and reimage the RIO.

Good luck!
