I stream via Ethernet on past and current versions of XiiaLive and I've never had a problem.
I've used WiFi on my FV-1 Android TV v2.2(Android v2.2) box and it works fine whether using Ethernet or WiFi.
Can confirm the alarm in v3.0.0 works on an XPERIA X10i v2.3.3 and an FV-1 Android TV v2.2.
One can set an alarm and have XiiaLive wakeup and fade in Music of your choice at the time you have set.
Setting a wakeup alarm in v3.0.0 works.
Can confirm on my XPERIA X10i v2.3.3 [rooted] that using the Google Playstore released v3.0.0 (05/09/2012 NOT beta) of XiiaLive, the alarm now works and can be set.
At the time that alarm is set to, XiiaLive fades in music and starts as one would expect.
This is also the case for the FV-1 Android TV v2.2 [rooted]. Bit surprised this works as it's just a Chinese 'desktop/media' box running Android v2.2.
But given one can set an alarm and it wakes up and plays music one is just happy it works.
XPERIA X10i v2.3.3 std and still getting "Alarm failed to be scheduled!" when attempting to set an alarm.
