We aren't sure how to check on that

Gaming adapter placement. Is your adapter away from the drive motors, battery cable, and also not surrounded by metal?

Yes

Also, you should check the CPU usage of the cRIO. You can check it from the driver station. If it is at 100%, your code is likely the culprit.

CPU usage is just fine

Do the symptoms disappear when you tether? Do they happen when your robot is stationary, or only when it is trying to move (under electrical load)?

Problems go away when we tether, but they do happen even if it's not moving.
@Alan: We checked, we aren't running it twice.

We're thinking it might be a bad router, but not sure yet.
