Hi agruber
Here is my setup: I live in a double storey brick home...
- ADSL line with Netgear N300 DGN2200v3 modem (upstairs)
- Time Machine (1TB) Ethernet connection to modem
Time Machine Generates WiFi signal
- Airport Express (1st Gen) in kitchen downstairs to extend WiFi
This setup works perfectly for connection with other devices - MBP, iPhones, SONY TV etc - no problems...
- Apple TV (3rd Gen) about 5 meters away from AE - WiFi connection near line of sight between AE & ATV
- Using Airplay from MacBook Pro (13" Early 2011) with USB (USB 3.0 able) WD 1TB HDD (ADSL is too slow for direct streaming, so download to USB drive, then use MBP to do Airplay)
So Apple stuff only - Time machine -> AirPort Express -> Apple TV, no windows or android to interfere here!!
The problem is that ATV will work perfectly the one day, the next day it will work for about 15min and then the ATV will give message that iTunes Homesharing is turned off. Go to settings of ATV and the WiFi connection will be there again. Continue watching program and it will quit every 2min or so - I get upset and reboot ATV, AE and MBP - or it will not give the error again for the rest of the day. There is no set sequence of failures to track to one specific event.
As stated, the one day I was quick enough to see the amber light flashing on the AE - do not know what this indicates (no WiFi, power supply etc) as I have no way of tracking the usage and general "health" of the AE.
(thanks Apple, for taking this function away with new AirPort Utility)
It flashes for about 15 sec and turns green again - this only happens when the ATV is busy with Airplay. Normal connection with iPhone, MBP gives no such problem - EVER!
The ATV has been replaced, but gives the same problem. I suspect now that the problem could be with the AE, but it is a passive device - just relaying information....
I'm contemplating getting the new AE, but forking out the money and still having the same problem is not ideal.
