None of my iDevices can read my iTunes library after an hour of availibility. When I first start iTunes I can read the library, but after about 30 minutes my iPad's and iPhones can no longer access the library. I see it in the shared list, but no access.

Windows 7 Ultimate 64bit inside a Domain.

2 720p ATV's and 1 1080p ATV

All components connected via Ethernet using Linksys Switches

Linksys E3000 Wireless router using 2.4 & 5ghz WiFi Freq's

iPhones on 2.4g & iPads on 5g

All latest Updates, BIOS, Firmware and Drivers installed everywhere.

SUCCESS! I have had overnight success. Last changes were to effectively kill sleeping except for the monitor!! 5 hours between attempts. Response was quick with album art filling in quickly.

This is the first success, more testing required and I will post my power parameters. My next test will be connecting right after work. 10 hour break. Will keep advised.

Have not had to restart iTunes since 22 May - Thats a full 24 hours, more importantly it's been an overnight and a workday.

Remember I previously unchecked IPv6 option in NIC Card settings. This is still the case.

As promised, my power settings are:

Turn off hard disk after : 20min

Desktop background settings: Slide Show: Available

Wireless Adapter Settings - Power Saving Mode: Maximum Performance

Sleep after: Never

Allow hybrid sleep: Off

Hibernate after: Never

Allow wake timers: Enable

USB Selective suspend setting: Enabled

PCI Express - Link State Power Management: Off

Processor Power Management - Minimum: 90% - Maximum: 100%

Turn Off Display after: 10 Minutes

Multimedia Settings - When Sharing Media: Prevent idling to sleep

When playing video - Optimize video quality

My changes listed above seems to have done the trick for me.

I don't know if the MAC platform has an IPv6 option that you can turn on/off

And I'm reasonably sure the power settings look a little different

Davids8477: Your testing suggests that there is a cache that previously loaded on the target device (laptop, iPhone, iPad, etc) The cache holds Album artwork and everything except the actual songs. The songs are not called up until you specifically request them. (forgive me if you know all this already). I discovered the same issue on my iPhone when I tried that same testing methodology.

Concerning your last two statements. Mine did not quit during a stream - at least I did not test anything that long.

But I did notice that each time I would completely close the app on my iPhone and reopen it, the information to be cached downloaded to my device at a slower pace than the last time, until it wouldn't load at all. Changing the IPv6 setting seemed to fix that issue. However it would still quit connecting after an extended idle.

(ex. Over night or while I was away at work). Then I changed my power config to leave everything on including Hard Drives and Monitor. Test still failed predictibly and the external SATA drive was getting quite warm.

I then decided to change the config to let the drives and monitor sleep, and it all started working again. It's been working since the 22nd. There have been no degrading info loads and no lost connections since then.

cendrizzi: I guess I should have put down the fact that I completely scrubbed my hard drive and started from scratch and that this did not work either.

Today will be day two of testing. If i get home and get a connection right away I will do a reboot - First one since it started working again, and do another overnight\work test. If i get a connection right away after that i can consider my system fully functional again.

Also there may be some BIOS Suspension/Hibernation settings playing a part in this issue - I just though about the fact that I have mine set to MINIMUM sleep / Restore faster - What I'd call the "Lightest Possible Sleeper" state.

Still going strong!! Will try rebooting and taking another long break

Davids8477: The reboot had no negative effect. Checked it this morning and it's still going strong!!

Good luck in your testing. And do keep us posted..
