Persistent failure of Bonjour-mediated iOS/MacOS Wi-fi after using WPA/WPA2

I do not clearly understand this, but there is no doubt of these facts. I've been doing this stuff since 1965, and I know how to isolate a problem.
My wife has been supplied by her job with a relatively antique IBM T-series Thinkpad, and she is expected to use it whenever she works from home. This elderly bit of hardware cannot, apparently, be upgraded to use WPA2, and so, from time to time, I have to back off our Time Capsule-based home network to WPA/WPA2 mode. (However, during my research, the actual Thinkpad has been miles away; it's not a factor in itself.)
This alone would be nuisance enough, but it is rendered a great deal more of one by the fact that, as soon as I do it, all my iOS apps that use Wi-fi to communicate directly with my Mac stop working, saying that my Mac cannot be found. The list includes Todo (Appigo) failing to find Appigo Sync, and SplashID (SplashData) and Splash Shopper (also SplashData) failing to find their Mac counterparts.
Worse yet, the effect is permanent. Resetting the network to WPA2 Personal doesn't help. Terminating and restarting the apps (yes, really terminating, not backgrounding) doesn't help. Disconnecting from Wi-fi and reconnecting doesn't help. Even rebooting both the iPhone and the Mac doesn't help. The only thing that fixes the problem is to reset the Time Capsule to factory state and then recreate the network.
I even tried creating a guest network and setting that to WPA/WPA2, leaving the main network on WPA2 Personal, but as soon as I did it, iOS/Mac communication broke down again, just as though I had changed the main network.
There is clearly a bug in either the Time Capsule firmware or the AirPort Utility. Whether this bug is itself the cause of the failure or merely uncovers a second bug (which might be elsewhere) I cannot say.

IOS 5 can't connect to WPA/WPA2 Enterprise Wireless Network

After upgrading multiple iPhone 4 (CDMA versions) to IOS 5.0, I have not been able to get them to connect to our WPA/WPA2 Enterprise wirless network. We use a Cisco Wireless LAN Controller. The wireless network is capable of doing WPA or WPA2 Enterprise with PEAP. These phones all connected to this network fine before the upgrade.
When connecteding to the network, it prompts me for the username and password and when I tap join it sits for about 10-15 seconds then says "Unable to join the network" with a Dismiss button.
It connects to non-Enterprise networks just fine. I have tested it on WPA Personal and WPA2 Personal networks and it has worked on several without issue.
I have tried "forget this network" with no success.
Is anyone else having this problem? I know of at least three Verizon iPhone 4's that have this exact same problem. I haven't seen one working with this configuration yet.

I have the same problem:
Cisco WLC's -> WPA2 Enterprise AES + EAP-PEAP 802.1x with CCKM
Pre 5.0 - all worked fine
Post 5.0 - it tries to connect and after few moments i get error - couldn't connect.

On the Radius server i don't see any activity regarding this device.
I had this network configured on my iPhone - after upgrade and restore it remembered it. Every time i was in vicinity of my Enterprise WLAN it tried to connect - resulting int express battery drain - 6-7 hrs and battery was empty from 100%

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Thank you

Well, if you did it yourself, then there is a chance that you damaged some other component inside the device that is causing your issue. The iPhone's are not user serviceable, and once you have opened the device you have voided any warranty and post-warranty support from Apple. I would try Google to see if you can find any other way to repair your device, as Apple will no longer look at it.

I have a iphone 4s with ios 8.3 and I used to be able to sync only a week or two of emails from outlook email. Now it won't let me do that and it syncs all my inbox. How can I change it back to sync less. I can't find the right place.

I understand, as that was the place I would change it before 8.3 but now that option of Mail Days to Sync is not available? Any idea why that would be?

Apple's response to my email:
"I understand that you can't update your apps using your iPad.
Apple is currently working toward a resolution for the issue you have reported. You will receive an email after the matter has been investigated and further information is available.
Thank you for your patience. Apple wants your iTunes experience to be as enjoyable as possible. Have a great day!"

After downloading iOS 7 I can't use my AppStore as another language than english appears...

After downloading iOS 7 I can't use my AppStore as another language than english appears... I am getting frustred!

I don't know if this helps, but I experienced a similar issue with my iPad 2 after updating to iOS 7.
My "solution" to the problem, after pulling out my hair for hours, is to plug it in the wall charger, and then shut the iPad down completely. It does charge when turned off, although a bit slower than usual, or so it seems. Pheeew...:-) I realize that this is a pain if you have a problem with an iPhone, because you have to turn it off to charge it. Presuming that this works, of course. Otherwise, I don't know..
After the update, the iPad simply does not respond when i plug in the charger, nor does it connect to the USB port. The battery just keeps wearing down. I think it could be connected to the firmware change that iOS 7 brings, which I guess in itself has to do with Apple wanting to block out 3rd party manufacturers of power adapters of the new "lightning" type.
The only thing I can think of that might have gone wrong on my part concerning the update is that I didn't have it plugged in while installing the update - although I believe this is recommended from Apple. I'm thinking that in my case the new firmware update simply hasn't registered any adapter present upon installation, and that might have caused the iPad to not recognize an adapter at all, regardless of type. I have always used original Apple adapters, btw, so I'm not really guilty of anything other than not plugging it in while updating - or, at least that's my own theory. Which is better than no theory at all.. ;-)
Obviously, I'm waiting eagerly for Apple to solve this issue. Not really happy at all with this..

IMessage stopped working on iOS 5.1.1 after I set up a new Apple ID. After logging in, it keeps cycling back to the "create ID" screen. Apple's verified my new ID. I've reset the iPod (3) times--no luck.

I solved my problem by Resetting my iPod and then Restoring my files. Only speed bump was losing two apps in the Restore, as the current versions now require iOS 7.1, minimum. Apple makes Reset and Restore (two processes) painless with these Help articles: "Use iTunes to restore your iOS device to factory settings," and "Back up and restore your iPhone, iPad, or iPod Touch using iCloud or iTunes." The Restore took a while to synch my photos and iTunes libraries.

Error 1669 after updating to ios 7, Error 1669 after updating to ios 7

Error 1669 after updating to ios 7, Error 1669 after updating to ios 7

how to solve error 1669
STEP 1: Delete iTunes from your computer. Also make sure you remove the cache(open itunes then press edit wich is located on the tool bar and then click on preferences and then go to advanced and click on reset warrnings and reset cache).
then go to your hard disk and go to program files and delete folder named itunes.
Note: If you have any libraries or locally cached data that you want to keep, temporarily store them somewhere until you get the situation fixed.
STEP 2: Once it is completely deleted, download iTunes 11.1 from Apple servers.
STEP 3: Download iTunes 11.1 from here.
STEP 4: Now connect your iPhone, iPad or iPod touch to computer.
STEP 5: Click “restore”, it should present you with a notification saying a new version is available.
STEP 6: Simply Click download and install, and sit back and relax.
The process should be completed and your error 1669 should be fixed.

Do you have iTunes 10.6.3?
If not, update iTunes first then try again.

Iphone 5 is updated from ios6.1.3 to ios 7.0.2, then use the machine to slow down.

If you "reset" the iPad, (restored the iOS) that should have installed the new software onto the device. But I am never sure what any user means when they use the term reset.
Some people use the term to mean restart. Some mean reset the system using the home and sleep buttons, some people mean that they restored the iOS software. How did you "reset" your iPad?
WHen you try to update, do you disable your firewall and antivirus software of using iTunes? Are you using iTunes? Are you using WiFi to update OTA?
