Tried and checked everything mentioned above. Finally, decided to restart the computer. IT WORKED.

In my case (iPhone 4, iOS 5.0, iTunes 10, Mac OS X Lion, Airport Wireless Router) I found that turning off my WiFi network adapter on my laptop and turning it back on made iTunes recognize the iPhone over WiFi.
Same thing here on Snow Leopard 10.6.8. Turning off and on WiFi did the trick.

VVinay's post was very helpful. I have had troubles getting the WiFi sync to work reliably. After much trial and error I have discovered the following for my Windows 7 x64 box:
(1) After checking the items in VVinay's post and rebooting my machine my iPhone 4 running iOS 5 appears to be discovered reliably and I can sync wirelessly.
(2) If I then start up a Windows Virtual PC virtual machine the WiFi sync stops working.
So it appears that Windows Virtual PC interferes with the proper operation of this feature, at least as of this writing. USB syncing still works as expected and if you attach the iPhone's USB connection to the virtual machine it works there as well.
Hopefully this will be fixed in a future update and my posting this here might save someone from pulling out too much hair if they too are running virtual machines on their laptops and finding that WiFi sync on the host OS isn't working. I haven't found a work around for this problem. If you have please post it here. Thanks.

I have a 4S, Windows 7, 10.5, new Linksys router. Same wonky issues with Wi-Fi synch. It just seems to randomly resolve itself. With all due respect to Vvinay's helpful directions, I don't feel I should have to do a liver transplant's worth of work to get this feature fixed. I paid too much for this stuff not to work as advertised and they need to fix it. What is really bizzare is that my phone appears in iTunes but it is not on the device list in iTunes like it once was?! Can someone explain that?

Wi-Fi sync doesn't work consistently for me, either. Lots of ideas in this thread, but they are all at best workarounds for deeper issues only Apple can solve.

I had the same problem! This seems to have fixed it!
- Log into your WiFi Router on Internet Explorer.
- Write down the Primary DNS of your Router. You should find it on the main page somewhere.
- On your iPhone go to Settings.
- Go to Wi-Fi
- There should be a tick next to the name of your Wi-Fi Router if connected. If not, connect to your Wi-Fi Router.
- Once connected, touch the little white/blue arrow pointing right.
- Make sure that DNS setting is the same as the one in (2) above!! If not, you can change it by tapping on the field.
I changed mine as it was different and my WiFi synch works perfectly each time. In fact my Laptop even starts iTunes if it is not open and proceeds to synch automatically now!! Your phone must be connected to power & and the WiFi Router obviously!
Let me know!

disconnect iphone from itunes , but keep itunes opened
turn off the power of the modem/router for a minute, then turn it back on.
reconnect iphone wi-fi again (disable, then enable it again)
open itunes wifi sync tab on iphone and 'sync now' button should be enabled

Make sure in Services that Apple Mobile Device is running.

I can see my iPhone and iPad in iTunes (when connected to power) and I can initiate a sync on any of the devices. But it doesn't "just start" automatically like I expect it to (or maybe my expectations are incorrect?). I've got iTunes running, I plug in my device, it shows up in iTunes - then nothing. It doesn't start the sync. Any idea why it shows up and syncs fine but only when I start it manually?

On the Mac, I discovered that IPv6 MUST be enabled in the Network panel of System Preferences.
For me, this alone solved the wi-fi sync problem.

On my Win7 Home 64 PC, I checked the Apple Mobile Device service (following other's suggestions); and although it was on I restarted it... success! All devices reappeared in iTunes!
I'm now going to make a Net cmd batch to restart the little blighter next time it plays up.

Well, it happens often and, as to me, I don't think it's an issue of Apple, OS or whatever else, rather than a Wi-Fi nowadays technology itself: let's be hones — even though it is popular it is not that good. But, getting back to your question — my solution (the one which works for me) is easy and quite — no hassle with password, nothing...
All you need is to renew lease of your device over the wi-fi network. Go to the Wi-Fi settings, click the blue arrow to get to the settings of the current network and click the renew lease button; launch iTunes — it's there your iDevice.
Personally, I've got two of them — and from time to time I'm renewing the lease — that solves mentioned issue.
With the Kindest Regard,

If you use PC with Windows try manually open iTunes and press sync button.
