iTunes Wireless Sync problem

[ajcgn]

I've been able to sync my iPad 2 and 3 and iPhone 4 wirelessly. I usually don't have to plug them in (to the charger) when I manually start the sync in iTunes.
I own the 2tb time capsule airport base station. I don't know if that makes the syncing easier, certainly my technical ability is not why the wifi sync works.

LOL. I appreciate your honesty. No, iPad doesn't sync with your time capsule, it sync with iTunes on your PC/Mac. But your time capsule does keeps a copy of your iTune.

I only managed to sync my iPad 1 on the wifi only once, the first time after I downloaded the iOS 5 point something that allowed wifi syncing. Since then it has never worked and there fore always been using the wire. Infact when the wire is not connected the wifi sync switch us greyed out and only becomes functional when the wire is connected. But the 1st time the sync worked perfectly cause I remember doing it from the bed and the computer was on the table and I could see the process on the iTunes screen and the entire update happened without a wire connection

Actually in your case you should have a good chance to get it back to work. Here are some tricks that I've gathered (excluding the ones that I've tried but didn't work according to Apple Support Forum).

Priorities as the following --

1. Disable all firewall and see if the problem is still there. Make sure you restart iTunes and disconnect iPad from the network and reconnect (This last step was really killing me since it was the single most important thing that cause the sporadic and seemingly random connection pattern. And it took me forever to find out on the forum.) If this works then it's your firewall itself or its setting that was causing the problem. In my case and in most cases reported in the forum, this was the reason.

2. Identify which application was causing the issue and configure your firewall accordingly. Some firewall (like my AVG) has limited configurability so I switched to Comodo and it even has a learned mode so I can experiment one by one.

3. Someone also suggested playing with your router. The two I knew people had successes were Upnp and IGMP snooping disabling. But I didn't bother to try them so good luck with that.

Hi,
I have windows xp pc and and ipad3. Almost randomly I got the sync to work after trying loads of different things. I had to register the itunes on the pc using my apple id. I plugged the usb cable in between the pc and ipad and it started syncing. I then noticed there is an option on the windows itunes devices ipad to sync over wifi. Is that the issue for people who upgraded - the option was turned off?

No problems here. WiFi sync works fine each time. I use it for both my iPad3 and iPhone. Never had to change any settings in the network. You do have to activate the first time with a wired connection.
