New Antennaes Not Connecting

I ordered several of the new white antennas after having issues with the old black ones. When I tested them, however, they would not connect. Is there anything I need to do before trying to pair them? I paired the cortex and controller with the orange cable before plugging in and trying to pair the antennas.

You’ve posted this in the IQ channel so might be worth moving to another category.

You may need to update the firmware on the VEXnet 2.0 keys - the tool for that can be found here:

Also be sure to download the VEXnet update tool and ensure that your Cortex and Joystick are on the last versions released too:
