I just did mine today ... after seeing this thread.
So .. to make it work.
- Assigned an ip via my router to the 536HP
- Connected Wifi dongle to 536HP and setup WiFi on the 536, SSID and Pwd using
infrastructure mode.
- Installed Siren app on my iPad
- Using Apple TV, and Air Play to screen mirror to my big screen.
The audio is bit lower than I would like .. but it works nicely.
