Greyed out "Sync now" button on iPhone 4 and iPad 2 won't let me synch to iTunes.

I had this problem when i got my phone recently. I read soemthing about old registries being messed up from auto matic updates and it recommended me to download a cleaner for that and after fixing the old registries and the usual check the "sync over wifi" box and rebooted my laptop, everything worked.

Here's the link to the article I read: http://cnx.com/?p=1612

I don't know if this will work for everybody, but I tried a lot of other methods such as restoring phone, uninstall and reinstall itunes, update firmware, and other things. This was the only solution that worked for me and was quick and easy. Hope this helps

That worked perfect. Thank you.

Finally was able to solve it and a big thanks to Pab @ http://cnx.com/?p=1612 - this article and solution works perfectly.

Even though I didn't followed it as specified, it works, here is how (in my case):

- Already had a itunes x64 version downloaded

- downloaded and installed CCleaner.exe (get it from cnet downloads,a safe version)

- Unisntalled ITUNES using CCleaner

- I didn't clean the registry

- Restarted the system

- Installed iTunes, did a manual Sync via USB, unplugged USB

- DID NOT WORK

- I already knew about Firewall so I confirmed again that WIndows Firewall is off (why because...) my Antivirus - CA Security has a firewall running

- So I went ahead and switched off CA Security Firewall for this test

- Next, tried iTunes - DID NOT WORK

- I went back to that article - this time I decided to clean the registry using CCLEANER

- I thought I might have to uninst-reinst Itunes first and then registry cleanup but I thought whats the harm, I have a fresh Itunes anyway so lets just try registry cleanup

- Did a Reg Cleanup with CCleaner

- So after registry Cleanup via CCLEANER - I open Itunes (note: Antivirus firewall is off)

- after few seconds - IT WOOOOOOOOOOOOOOOORK

- tried Sync, it works over wifi - and WITHOUT MY PHONE PLUGGED INTO POWER - it just works (have to wait for few secs though in Itunes)

- So closed Itunes, restarted Itunes - after few seconds - it works fine

- Next enabled the Anitivirus firewall - and tried sync - it fails

- Disabled the firewall again - and it starts working again

Bottom Line

=========

Read that article - follow the instruction

Ensure about all your firewall - wondows and/or antivirus-based or any other if u have - and how to allow all apple apps to pass through it

=========

For me if I enable antivirus firewall it doesn't work, otherwise it does. Will find some remedy for that antivirus firewall but as of now am happy, I saw it working 🙂

Ok, tried all but still no luck. Windows 7 64 bit, iPhone 3gs and iPad. iPad is detected and syncs perfectly over wifi, iPhone not detected in iTunes and wifi sync grayed out as per other examples. Stumped...not a major problem, as will be replacing with 4s 64gb as soon as I can find somewhere with stock!

I have Win 7 64-bit, iTunes 10.5 and iOS 5 on my iPhone 4S and iPad 1. Cannot get wireless sync to work. I even replaced my DSL/Wi-Fi setup with a wired DSL router and Apple Airport Extreme. Still no dice. I can sync just fine when connected via USB; device just disappears from iTunes when unplugged. Even with Windows Firewall and my Anti-Virus disabled, no dice. "Sync now" button grayed out on iOS devices. Very puzzling. I am assuming that the Apple Airport Extreme should be set up to work for wireless sync by default. I am also assuming (and hoping) there is just a bug here which will be fixed soon. I've seen lots of issues with recent ATV2 updates; so it's likely there are other issues that need to be ironed out in iTunes and iOS...

I know its annoying issue. But am also sure the steps in this article does solve the issue - http://cnx.com/?p=1612 - You have to try few things for your scnario. I will suggest this - it helped me a lot for other issues in iTunes normal usb syncs also earlier. There is a specific 'itunes and other apple related apps removal steps' on this forum somewhere, I will post that if I find it.

Idea is - remove all stuff from WIN coming from apple (mind it, there is a step what to remove after which one).

remove them with CCLEANER I will suggest.

Restart system

Clean registry (CCLEANER again)

Restart and do a fresh installation of the itunes and other apple apps that u use.

Keep all firewalls off when u try sync

First do the normal usb sync, let is complete

and then try wifi sync

Best of luck... one more try that is 🙂 don't give up.

Hi Pankajno1,

Yes I tried everything at the link above - uninstalled everything, cleared the registry, reinstalled, etc. Even tried the "netsh winsock reset" clearing trick -- still no dice. I am convinced there are some serious bugs since I am using an all Apple Wi-Fi network which is all just supposed to work together.

Thanks,

Kevin

It should work, sorry am not much of help. But one more thing I wanted to check for your scenario is (though I don't have that device) - your Airport Extereme is set to work on 5ghz or 2.4ghz? becuase both ip4 and ip4S support only 2.4gzh for a 802.11n wireless, set it to 2.4ghz if not done so far and check.

Regards

Pankaj

I have my Airport Express in "Automatic" mode to select the Wi-Fi band. Do I need to change this?

Kevin

I would have certainly tried that. I have seen many other posts related to Airport Extreme, there are videos on youtube how to change that setting. I will assume 'automatic' is going for 5gzh by default, so give it a try, change it to manual and select 2.4ghz.

What about my Apple TV (I have both ATV1 and ATV2)? Do these only work on 2.4Ghz as well?

Thanks,

Kevin

2.4gzh restriction has been given only for ip4 and ip4S, tried looking for ATVs but I don't see anything so I will assume it works on both stream i.e. 2.4ghz and 5ghz. Do you have issues on ATVs also? Did u try ip4 test with 2.4gzh. Sorry if am killing your time, just want to help u out if I can.

I should have mentioned before that my iPhone 4S connects just fine to the Wi-Fi network via Airport Extreme using 802.11b/g/n (per AirPort Utility on my phone).

Kevin

Also, the Airport Extreme uses both 2.4Ghz and 5Ghz depending on which device is connected.

I see 802.11a/n (5Ghz) is being used for ATV2 while 802.11b/g/n (2.4Ghz) is being used for iPhone 4S.

So looks like the correct Wi-Fi channels are being used.

Would double NAT create such a problem? I have a Motorola 3360 DSL Modem, but it's not clear if I have a double NAT issue (Airport Extreme (AEBS) is not reporting a problem). I can't find any documentation on the 3360 device to fully understand its capabilities.

Here are my IP addresses:

Motorola 3360:

(a) Public IP Address: 69.232.196.67

(b) LAN IP Address: 192.168.1.254

Airport Extreme:

(c) WAN IP Address: 69.232.196.67

(d) LAN IP Address: 10.0.1.1

The fact that (a) and (c) are the same tells me the AEBS is sharing the modem's public IP address (which is what AT&T asked me to set up). They asked me to set up the following option: "public IP address assigned to the modem be used by the local LAN device". So this explains why the AEBS WAN IP is the same as the DSL modem public IP address.

However, shouldn't (d) be on the same subnet as (b)?Should I disable DHCP and NAT in my AEBS? I know the DSL modem supports DHCP from the tech log; not much to configure here.

Or is my configuration OK?

Kevin

Thanks,

Kevin
