There is an ethernet cable which you plug into at the driver station. From there the Field Management System (FMS) takes care of the rest. You will set a unique WPA key on your gaming adapter when you get to the event. That info is stored within the FMS and the field's routers are synched every match to host networks that match those WPA keys. Once the scores for the previous match are shown and the match is advanced to the following round (that you will play in), the routers are reconfigured with those WPA keys and your gaming adapter will connect to it.
