If I had this problem on our robot the first things that would come to mind would be to:

Make sure the watchdog is fed. There's an indicator on the bottom left that will tell you if the watchdog has died.

Make sure the jaguars are plugged into the correct ports for the simple robot demo and that your joysticks work (I would write a simple autonomous that simply drives forwards to see if that works to make sure the jaguars are functioning)

If your problem is still there after that then keep us updated!

edit: To answer your original question about if you need to change any settings on the driver station, are you using the classmate driver's station? If so, as long as you have a green light next to robot communication and one next to robot code then you should have a connection. Also make sure you have updated it!
