Automatic wifi sync not working

Same problem here. Wifi synch works amazing, just not automatically as it says.

I have been wondering the same thing. I've met all the requirements, iTunes open, WiFi sync checked, same network, iPod plugged into power, iPod appears in iTunes, iPod not synced in the last at least 24 hours, I have even turned off my firewall in case that was a problem. WiFi sync works great, but no automatic sync, yet. When does automatic sync kick in? Is there a specific time it waits for, like 2am?

Same problem here. Syncs great when I force it, but never automatically syncs when hooked up to power.

Adding my voice to the chorus. Anyone find out anything helpful? Are we all on the same devices? I'm on an iPhone 4 - AT&T.

Figured it out - there's an option under the preferences menu then the "Devices" tab that reads "Prevent iPods, iPhones and iPads from synching automatically." Make sure that is unchecked - that was my problem.

Mine's actually doing something far more irritating.

It does seem to sync some content automatically (i.e., app arrangements, changes to installed software, etc.) almost all the time, which is nice.

However: Whenever the iPhone is on and in range of the WiFi network, and iTunes is launched on my computer, the Usage meter just keeps racking up the minutes as if the phone is constantly ON. Even though there is no visual indicator of synchronization taking place, it seems as if something is running constantly on the phone.

The end result of this is absolutely abysmal battery life. I can watch it get sucked down from 100% to 85% in about 45 minutes.

If I quit iTunes, then the phone stops counting Usage time, and battery life returns to normal.

Has anyone seen anything like this? If I keep iTunes running and pull my iPhone off the charger, then Usage time will equal Idle time right up until the battery dies. If I turn off iTunes, or turn off wireless syncing, the phone goes back to normal.

So odd!

Good find, unfortunantly, this didn't fix any of the issues I'm having. Mine was unchecked by default.

Neither my iPhone 4 or my iPad will sync automatically.

Ok, i finally got automatic sync working. I had the same problems as others - could do a manual wireless sync from the iPhone Settings App, but automatic sync would not start when plugged in and charging. The iPhone showed up in the iTunes sidebar, the "Sync with this iPhone over WiFi" option in the iPhone settings in iTunes was checked, the iPhone and Mac were on the same network (over WiFi - no ethernet connection), and the "Prevent iPods, iPhones and iPads from synching automatically" option was NOT checked, and i still couldn't get automatic syncing to work.

Here's what i did

- made sure the iPhone was showing in the iTunes sidebar

- turned off WiFi on the iPhone, leaving it still showing in the iTunes sidebar

- Ctrl-clicked on the iPhone in the iTunes sidebar and selected "Sync "iPhone"" (the name may be different depending on your device and what you've called it)

- Let iTunes work trying to sync the iPhone it couldn't find until it showed an exclamation mark where the eject symbol is in the sidebar

- hot the eject/exclamation symbol and waited until the iPhone wasn't showing in the sidebar

- Connected the iPhone with a cable and let iTunes re-recognise it

- in the iPhone settings checked "open iTunes when this iPhone is connected" option and hit Apply (NOT Sync)

- Ejected the iPhone in iTunes

- turned the iPhone WiFi back on and let it connect to the WiFi network

- made sure it was showing in the iTunes sidebar

- connected it to my charger

- and wireless syncing started automatically!

Probably not all of this is necessary - I'm not sure which step fixed the problem, but my guess is the "open iTunes when this *** is connected" preference is the important one. Also i hadn't synced my iPhone in a couple of days, so that might be important. My guess is it won't start automatic sync if you've synced it relatively recently.

I followed these directions... and it worked! It started syncing when I plugged into power o_O Maybe it's the open iTunes when device is connected option or something. I can't wait to see if it works again tomorrow or if I'll have to repeat the steps, that wouldn't be convenient at all.

I can verify, that you only need to check "Open iTunes when this xxx is connected" for it to work.

This is obviously either a UI bug ("Sync with xxx" should be disabled if "Open iTunes" is unchecked), or a operational bug. Since I'm a developer, I added this as a bug (10313902) so Apple is aware.

What I did was follow the directions I posted above then:

1. Shut down iTunes
2. Turn off the iPhone
3. Restart iTunes
4. Power up the iPhone

From then on my iPhone auto-synced.

I have been trying everything from every post for the past few days but nothing had fixed the auto syncing issue over the wifi until just before. All I did was visit the iTunes store from the itunes itself ( I specifically visited the new link called Purchased) and suddenly both my iPhone and iPad have started to auto sync. Infact they auto sync every time I unplug and plug into the power source. Only one issue remains - for some reason the itunes looses both the devices if I turn the Airport off and use only the Ethernet connection.

This worked for me, too. I don't know why I didn't think to just power down my iPad. I also clicked on the "Purchased" tab at the same time so there is a small chance that that helped, too, but I suspect is was simply powering off and back on again that did it.
