Not able to see Ip Address in port menu

So im connected to my Universities network, eduroam, and so is my yun. I am able to go to yun.local and pull up the information on the device and get the current ip address and everything. I am not able; however, to see the device in the port menu. Any ideas on how I can see/connect to it without serial?

@mdfitzpatrick,
are you on the same network and router as the Yun?
