My roamio pro is connected to the network using wifi. impossible for me to hardwire (even using moca) in my house. i installed the ipad app, entered the media access key, and connected to the roamio. i see a listing of my shows and can control the roamio using the ipad's remote. but when i try to setup streaming on the ipad app, i get an error that no streaming devices are found. roamio pros should have streaming capabilities built in. is it not possible to use streaming (or downloading to the ipad) when the roamio is connected via wifi?
