vexnet lights

We are having difficulties getting the vexnet to work with the wireless keys. The joystick controller is displaying all red lights after it tries to connect and fails.

Hello rhys.south,

Thanks for taking the time to visit our forum.
In order to understand your issue I will need more technical details, please elaborate further into your problem.

Does your robot works in tether mode?
Are you running VEXnet 1.0 or 2.0?

Please confirm.
