Re: Driver won't communicate with robot
This would initially appear to be one of three cases:

Network congestion. Are your robot and driverstation the ONLY two computers on the network?

Wifi congestion. Are there other networks in close proximity that utilize the same channel that might be interfering?

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

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.

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)?
