I would say connect the switch to the router and then connect the Pi and the F16 to the switch. As far as the config and how the PI talks to the F16, I am not sure since I don't have an F16. However, I would think that the PI needs the channels setup for the F16 to receive the data. Maybe someone with that setup can help to get you going. Once you have that part configured and working then adding a wireless dongle to the PI then that should be a no brainer. I noticed on another post that there is a known wireless dongle that will work with the PI. Once you have a wireless dongle then you can disconnect the PI from the switch. I would assume at that point the router will connect to the PI wirelessly.
