This thing seems to work about half the time. Tried to watch shows while on a trip this weekend on my iPad...it can't find the receiver. I come home, reinstall the app, it works fine while on the home network but as soon as I turn wifi off, it can't find the receiver anymore. Not the first time it's happened to me and judging by other posts on various forums, others have the same issue. Seems like sometimes it works, sometimes it doesn't. Is there any sort of "fix" I can try other that what I've done?
