When you are on your home network, the audio is passing from your orb host PC say (192.168.1.1), to your iPhone (192.168.1.3) or whatever.
When you are at starbucks or some other wi-fi hotspot your iPhone has to find you orb host PC over the internet.
I am just saying if you iPhone communicates with orb over your home network does not mean it will work over wi-fi from a public hot spot.
I hear what you are saying, but it makes no sense. I have used dozens of wifi areas and they all work fine with Sirius. The orb software is specifically designed to work when you are NOT on your home network.
