YUN won't upload over WiFi

I have the YUN on the same network as the computer, but when I try to upload a sketch, there is no IP option in the TOOLS / PORT menu. . .

I have even tried with a different computer ( Both Mac OS X ) IDE 1.5.8

Any ideas ?

Thanks

Gary

I have tried with both Ethernet connected and disconnected. I can upload to the board over USB. I can open the Dashboard over Ethernet and WiFi. I can SSH to the board. Just does not show up (IP) in the menu
