Are the Zen Stream and your phone/iPad on the same Network? Also when doing the complete setup of the Zen Stream in the Stream App you have to press the save button in each section where you make a change. Also make sure you have check for software updates. Once you have the Zen Stream completely setup using the iFi app then see if the MConnect app will see it. If not shut them both down and re-boot them both, Zen Stream first. If you never used mConnect before there is an instruction guide on the companies website that I posted in another thread earlier about the app. Also check out the Tips and Tricks thread at Headfi. In that thread there is a step by step guide to setup. It needs to be done in order.
