Upgraded to iOS 4.2 and iPhone no longer connects to AT&T Network.

Title pretty much sums it up. After updating to iOS 4.2, my iPhone 4 no longer connects to the AT&T Network. It just says Searching and rarely finds the network. When it does, it shoes 1 bar and as soon as I try to send a text or make a call, it goes back to Searching.

Reverting to an earlier firmware version is not supported.
Stop by a local AT&T store reporting the problem and request a new SIM card where the new SIM card can be activated with your iPhone. There will be no charge for this.
If no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup and no change with a new SIM card, the iPhone includes a one year warranty. You can call AppleCare or make an appointment at an Apple store if there is one nearby.

  • Why is it that when i upgraded to ios 6, my ipad 2 no longer connects to known networks automatically

    why is it that when i upgraded to ios 6, my ipad 2 no longer connects to known networks automatically?

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

  • TS1398 Updated to ios6 now lost all wifi connection both iPad and iPhone no longer connects to wifi

    Updated to ios6 now lost all wifi connection both iPad and iPhone no longer connects to wifi

    not much response in here which surprises me...
    Anyway... AS I am still looking for answers, I will share a couple of points that I realised...
    in Airport Utility, I noticed that my iphone MAC address was actually showing as client connected, despite my phone network showing the spinning wheel next to the network name for ever and never actually connecting.
    I am currently testing the router mode in Network to be on DHCP and NAT mode with a range from .2 to .200
    My phone is now connected....
    Everything seems to be ok and happy so far...
    strange that this router and phone have worked together for at least a couple of years, the phone works everywhere else, and all other toys connect to my WIFI just fine. the list is as follow:
    airport extreme
    Zeppelin air
    2x apple tv
    2 ipads
    iphone 4s
    2 mac
    1 pc
    I have litterally just hard reset the router with a pin just now as a last resort... same...
    I will leave the router as DHCP & NAT until a potential firmware or OS update...

  • HT1695 i downloaded the IOS software upgrade and can no longer connect to any WiFi network, what can I do to fix this?

    I have attempted to reset the network settings, nothing changed.  The wireless router is working and has nothing wrong with it.  Ever since I downloaded the software update, WiFi connection can not happen and every time I try to do anything that uses the internet it directs me to the apple support site.  How can this be resolved?    

    I've tried the following:
    * Settings | General | Reset | Reset Network Settings (Twice)
    * Settings | General | Reset | Reset All Settings (Once)
    * Plugging it in and doing a "Restore" through iTunes (that's how I downloaded iOS 5.1.1 in the first place)
    All the passcodes and restrictions are are turned off.
    When I first try to connect to the network, I'm prompted to enter my username and password (I've elected to "forget" the network a few times so I can get this screen again). If I enter it wrong, then I just get an error that I'm not connected. When I enter it right, I get a warning that the certificate is "not verified". When I click on "More Details", I can see all the information that got pulled from the network (Issuer Name, Signature Algorithm, Public Key Algorithm, Key Usage, etc.). When I choose to "Accept", I get the little icon indicating that it's trying to connect...this never goes away (I let it run for an hour).
    The encryption type on the main Wifi I'm trying to connect to says it's RSA (I'm guessing it's WEP though...I didn't set it up, our IT group did that).

  • After upgrade to IOS 8.3  iPad Air no longer connects to iTunes

    Today I upgraded my Macbook Air to Yosemite 10.3 and my iPad Air to IOS 8.3
    After upgrading the iPad I was asked to connect it via cable to iTunes in order to allow for wireless sync.
    When plugging the cable in, the iPad starts sending endless alert beeps and the top line of the screen is shaking. On iTunes the error message "iTunes could not connect to this iPhone. This device is no longer connected." appears with every alert beep from the iPAD. No matter how often the OK button is pressed, the message appears rightaway again.
    I made a full backup of the iPad Air before upgrading to IOS 8.3 but I am very reluctant to reset the iPad as the same error might come up when connecting the iPad after reset to iTunes and then I would not be able to restore it at all.
    Does anyone had a similar experience and/or is there any known workaround?
    Many Thanks for any suggestion.
    G.W

    Thanks for your further consideration, much apreciated. I tried a different cable, different port and did reboot and soft reset. I also did reset of settings on iPad, just in case.
    As  I can with no problems use the same USB cable and USB port with my iPhone to connect to iTunes, the issue must be somewhat with the iPad Air and iTunes on my Macbook Air. I also can connect the iPad with the same USB Cable to iTunes on a different Macbook with no issues.
    I think, best is to do a full backup on a different machine and then setting back the iPad to initial state, followed by a restore.
    This I can (hopefully successfully) do with iTunes on a different Macbook.
    Many thanks for you kind support.

  • Ipad and iPhone no longer connect to iTunes, just get spinning wheel

    I have a iphone 5 with the latest IOS software and a Ipad 3 again with the latest IOS software and I used to connect them to my macbook pro 2013 model (Maverics) through a USB cable for backup purposes.  Now when i try to connect to Itunes all I get is a spinning disc and no functionality.

    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    ~/Library/Application Support/SyncServices
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item selected. Quit the application if it's running. Move the selected item to the Trash. Relaunch the application and test.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

  • Downloaded iOS 5.1 and can no longer connect to any encrypted Wifi?

    I just downloaded the latest iOS and did a full factory reset on my iTouch in hopes of getting it ready to go to a co-worker. I've been test-driving the device to see if we wanted to use Apple vs Android products for the applications we're developing for our research facility. Things were going fairly smoothly until I did this. Now, I no longer have access to any encrypted network (I have access to 2), which essentially has given me a nice paperweight I can give to my co-worker (we deal with HIPAA information that has to be encrypted). It does have access to guest networks, so I know it's a software problem (not a hardware problem). I tried calling Apple, but we're outside our 90-day limit. I thought they were known for their excellent support, but if I have to pay for fixing something their update broke (sounds like a great way to make money if you ask me), I won't be recommending it for our software development.
    Anyone aware of any settings I need to dig-into to get this to work? (I feel like my hands are tied because I can't poke around in any of the directories to browse through files and settings; something I'm not afraid to do as a software developer.)

    Reboot your router by turning it off for about 15 seconds.

    Who can shed some light on my ongoing connection problem.
    After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
    I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
    So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
    I tried all things of resets and forgets. No result.
    I have been fondling with my Airport Extreme 5 , but that did not help much.
    This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
    I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
    Ideas anyone ?

    Yes I tried this manyfold. But did not work.  Reading on, I took Tesserac's advice. Shut down router and computer.
    Start router after 15 minutes and wait another 10 minutes before starting the computer.
    Et voila.... everything is back in working order,

  • I just upgraded to IOS 5 on my iPhone 4 and how do i get my LED light to flash for notifications?

    I have the iPhone 4 and just upgraded to IOS 5 today and saw that there is an LED light that can flash for alerts. How do I turn this on?

    I saw that this seems to be a widespread issue and is independent of third party music apps, so in the interest of helping things to consolidate, I've started a discussion that links to other relevant discussions I could find. Here's the link: https://discussions.apple.com/thread/3456073

    No. If you failed to turn off Find my iPhone BEFORE you upgraded to iOS 7, you will need the original Apple ID and password. If you upgraded to iOS 7 you will need this info; there is no way around this. If it is the device passcode you will need to restore your iPhone in order to reset that, which in the end will require your Apple ID and password in order to activate the phone once it is restored.
    Why don't you have the original Apple ID? Where did you get the phone?

    You got it downloaded and I assume you mean it is installed as well.  It was buggy for me.
    I had to close and restarted iTunes before I could use it properly.
    Then, I had to unplug and replug in my phone before it recognises it.
    Just had to try everything.  As final choice, update over the air.  I try to avoid it as it tends to have more problems than a tethered update.
