Arduino 2:1.0.5 ide cant detect yun shield over wifi

Hello
I'm setting up my Iduino yun shield for the first time and everything was running smoothly until I checked my serialPort option under the tools menu and I get no iduino wifi option, just the same regular old (USB0).
do I need to do something with the firmware or what? the board pops up on the menu as Arduino uno --Iduino Yun but thats it. Also I'm running this off of a Raspberry Pi3.

Thanks For Listening
Any suggestions would be much appreciated
