iPhone 5 will not sync over wi-fi, "sync will resume when PC is available"

I don't have an answer for you but from my experience iOS WiFi syncing has always been a hit and miss affair (more miss than hit I'm afraid). I have gotten to the stage where I rarely use the WiFi sync. It is just quicker, easier and much less stressful to use the USB cable. I am having the same issues with all the iOS devices in our family which includes various models of iPhone, iPad and an iPod Touch and have been having them since WiFi syncing was introduced (in iOS5 ???). And then I have not even mentioned my favorite iTunes syncing messages: "Waiting for items to copy" and "Waiting for changes to be applied"! 😮😕

iTunes is always extremely quick and eager to pick up the devices but as soon as I click on sync it shows "Looking for iDevice" and then the device disappears. I have found that initiating the sync from the Settings app on the device prevents this issue.

It does however seem as if it is worse with Windows 7. I did not have so many issues with my previous Windows Vista PC.

Sorry I cannot be of any help.

I am sorry to say that I have had the identical problem for about 6 weeks, and have tried all the techniques you described, similarly without success.

I can say that the problem started immediately after an iTunes update (11.1.4) and has not been corrected with the subsequent update 11.1.5, so I do suspect that the problem is iTunes itself, although Apple has not so indicated.

I even went so far as to upgrade my iPhone from a 4s to a 5s, OS 7.1. No problem with sync via USB cable, but still no wi-fi sync, although the phone does seem to be recognized by iTunes. No sycn even when initiated from the phone settings.

Since wireless sync worked up until the iTunes update, I don't think anything you or I do will be successful until Apple recognizes the problem and corrects it in a future version of iTunes.

Another ill-fated attempt:

I was at my daughter's for the holiday, and brought my laptop. (I have never used this laptop to sync iPhone previously, just my home PC)

So now I tried

-my new iPhone 5s OS 7.1

-a different machine, the laptop

-a new installation of iTunes latest version 11.1.5

-a different USP, modem, and router

No surprise. Hard wired sync worked fine, no wi-fi sync at all.

What this experiment did convince me of, however, is that:

It is not a modem or wireless router issue,

It is not some fluky setting on my PC,

It is not my hardware at all.

The only unchanged variable producing the problem is iTunes.

Maybe 11.1.4 created a disabling registry setting, and reinstalling 11.1.3 could not undo that change.

Similar results with my wifi sync. It works maybe 1 out of 25 tries. Fiddle with setting, fiddle with power off/on, fiddle with usb sync, fiddle with eject/no eject ipad from PC. Totally unreliable [feature]. No effective help from Apple Support fora; heads burried in sand. Pathetic.

Maybe good news, finally...

After months of no WiFi sync, I updated to the just -released iTunes 11.2.2.3, and WiFi sync finally worked. It took a couple of attempts, each cumulatively getting a bit further with the sync, but it was successful. Had to open and close iTunes a couple of times, re-sync, etc, but it does work. It was iTunes all along, as nothing else has changed. Hope it works for you as well.

I had the same problem but I was finally able to fix it. TIf you still haven't fixed this you can ry this. Go to control panel > rogrms and features > find the apple mobility device support > right click and hit repair. After I did this I had no issues syncing over wifi. Hope this helps!

I finally made an account just to say THANK YOU linders09!! Your fix worked for me! I had been having problems with this forever and after finding 'Apple Mobile Device Support' in 'Programs and Features' and then repairing it (I did it twice, could have fixed it the first time, but I didn't immediately see the change on my phone so I repaired again) the SYNC NOW button was no longer greyed out and I've successfully synced my iphone 5! Thank you thank you thank you!

Greaaaaaaaaaaaaaaaaaaaat man, thank uou 😉

i just had to make a comment too that your idea helped 100% the second it repaired the apple mobile device support both my iphone 5s and ipad mini 2 were immediatley able to sync via wifi!!!!!

Awesome, worked like a charm. Not right away (for me) so I just restarted the Apple service, relaunched iTunes and voila, problem fixed. Thank you for sharing!!!

Thank you linders09! Worked perfectly.

I've tried the Control Panel/Programs/Features/right click on Repair -- okayed it to make changes to my computer -- took a couple of seconds, tried again to sync on my phone (signed in to itunes), connected my iPhone via USB and from my iPhone clicked Settings/General/iTunes Wi-Fi Sync (even though it wasn't highlighted and obviously didn't work -- sigh). I've done this 4 or 5 times, all in vain. I go through this every couple months when I want to sync my phone to my computer and sync my computer calendar to my iPhone -- it truly is maddening! Writing Apple about this has resulted in NO reply at all.

My iPhone 5S is now 2 years old. It's in perfect condition, so I hate trading it in for the unknown, but I really need something that I can get support on and something that will sync easier.

Anyone have any suggestions? This is my first iPhone and it may be my last. Thanks!
