WIFI intermittent connectivity issues after upgrading to iOS 8.0.2

Hi,
WIFI seems to be dropping a lot after upgrading to iOS 8.0.2. I even took the iPad back to Apple and they replaced it with a new one with iOS7, which was working fine, then the same problem resurfaced after upgrading to iOS 8.0.2. I can't use my iPad in the evening at all.
My iPhone is fine after the upgrade though.
Clearly an iOS8 software issuse on iPads?
Thanks

Similar thing happened to me..  Seems like the bug has not been solved.. I managed to restore to iOS 8 and this resolved the issue, at least for the time-being!
     Apple team, my sincere request to you:Please attend this bug asap. It really dissolves the purpose  of an iPhone..
Keeping my fingres crossed till then!

  • I am facing wifi and mobile 2G signal issue after upgrading to IOS 6 from IOS 5 in IPhone 3GS. Please help, restoring setting even didn't helped.

    I am facing wifi and mobile 2G signal issue after upgrading to IOS 6 from IOS 5 in IPhone 3GS. The mobile carrier signal as well as WIFI suddenly drops zero and are then restored automatically. Sometimes i cannot conenct to WIFI even standing infront of WIFI router. Please help, restoring setting even didn't helped.

    Update: my phone's connecting to the WiFi again. I don't know what did the trick. I did nothing since reinstalling the software. It hadn't worked then, it is now. I tried connecting to my dad's phone's hotspot( he uses a Moto G), and it worked. I then tried connecting to the WiFi at a friend's house, and when I came back home, my phone was able to connect to my WiFi! Is it of any significance that my friend's router doesn't require a password? My issue has been resolved( for now; I hope I'm not counting my chickens before they've hatched). For anyone facing a similar issue, I suggest you try everything I did:
    1. Turn your router off for a minimum of 30 seconds, turn it back on and try connecting.
    2. Click on the WiFi network you are connected to, scroll to the bottom, tap "Renew Lease".
    3. Do a soft and hard reset.
    4. Reset network settings.
    5. Back your data up, erase all content from settings menu, restore from backup.
    6. Reinstall your software( put it in recovery mode).
    I am not sure which of the above worked for me. Make sure you try everything. If none of the above works, take it to a genius bar or an authorised service provider. Good luck! :)

  • IPhone 4s issues after upgrading to IOS 8

    Have few issues after upgrading to iOS 8
    - Phone hangs every few hours, reboots automatically
    - Bluetooth does not work properly (call does not get disconnected or even if disconnected on phone, the car bluetooth shows call is on)
    - Searching for contacts is a problem
    - Apps hang (especially facebook)
    Any way to go back to iOS 7 ?
    Any other tips / tricks appreciated..
    Venkat

    No way to come back to iOS 7 ...
    But did you tried to reset all settings (general -> reset -> all settings) ?
    For me iOS 8 was a mess on a 5S, especially car Bluetooth, and all works now fine after resetting the settings (all settings, not only network settings).

  • WiFi connection broke after upgrading to IOS 6.0

    My WiFi connection stopped working after upgrading to IOS 6.0 on bothe iPhone 4 and iPad 3.
    I reset the Network connection - no change.
    I selected "Forget Network" and tried to rejoin - no luck.

    You are not addressing Apple here. We are just users like yourself.
    Does the iPod connect to other networks?
    Does the iPod see the network?
    Any error messages?
    Do other devices now connect?
    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router

  • Freeze/Battery issues after upgrade to iOS 8.0.2

    Since upgrading my 3rd Gen iPad WiFi to iOS 8.0.2 I have been experiencing freezes where nothing works. I can't open apps or do anything. If I hold the on/off button down eventually it comes back to life.  Second issue is battery life.  Last night I closed my smart cover and made sure the display was off.  Battery at the time was 62%. This morning I opened the iPad smart cover and the battery was down too 23%.  This has happened a number of time over the past week or so. I have Blue Tooth and Location Services off.
    Both of these issues are new after upgrading to iOS 8.0.2.  No problems whatsoever prior to that.
    Not sure if I'm putting this in the correct category or not.
    Is there a way to wipe the iPad clean and reinstall everything from scratch or is my iPad just shot?  Thanks in advance.

    Same sort of issues here on my ipad3. iOS 8 turned it from a nice slick device into a jerky, laggy pain. Tried all the reset options and it's still pretty crap.
    NIce one apple, I'm changing to a galaxy tab after you broke my iPad!

  • HT4528 iPhone 4s' wifi doesn't work after upgrading to iOS 7

    My Verizon iPhone 4s will not connect to wifi after upgrading to iOS 7. You would think Apple would have figured this problem out before releasing iOS 7 to the public. Any fixes?

    After having trying everything out on the web, I found a fix that worked out. The thing to do is to deactivate your phone and then reactivate it. The way to do it is to first power off the phone. Then take out the SIM card. Then power on the phone and make an emergency call for about 5 sec. Turn the power off. Place the SIM card back into the phone. Power on the phone and plug it into the computer and to itune. Itune will then ask for your user name and password. The wifi will be working.
    All you have to do then, is reinstall your saved restored file.
    That's it !!

  • Sync issues after upgrading to ios 7

    After upgrading to iOS 7 on my iPad 3 with no problem at all, I lost all my music. When I try and sync with iTunes 11.1 (on Windows 7) it hangs on the last step "waiting to apply changes", and the little sync icon on the iPad disappears. I can't even add or remove apps. Any solutions out there?
    Thanks in advance.

    Try a Restart. 
    Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
     Resetting your settings
    You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
    Resetting your device
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
    Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple. 
    Here is a link to their contacts with most of the information below.

    If we try to enable it manually from CLI we get the following message:

    VSA will NOT come up until system power-cycle or reload

    Is VSA incompatible with IOS 15.x? I'm asking because downgrade to 12.4 causes VSA to be active again.

    Igor

    Hi igor,
    1) FDP image
    Field-programmable devices (FPDs) are hardware devices implemented on router cards that support separate software upgrades. An FPD image package is used to upgrade FPD images
    The FPD image package must be compatible with the Cisco IOS software that is running on the router. If an incompatibility exists between an FPD image package and the Cisco IOS software release running the router, the device with the FPD will not operate properly until the incompatibility is resolved.
    The FPD automatic upgrade feature searches only for the FPD image package file that is the same version number as the Cisco IOS release being used by the system. For example, if the Cisco IOS release being used is Cisco IOS Release 12.4(5)T1, the system searches for the FPD image package file that supports the specific Cisco IOS release (c7200-fpd-pkg.124-5.T1.pkg).
    2) Steps to Upgrade:
    From the document below which I already sent you, please refer to the section “How to Upgrade Field-Programmable Devices”
    http://www.cisco.com/en/US/docs/routers/7200/configuration/feature_guides/fpd.html
    I would recommend you to follow the steps in the “Field-Programmable Device Quick Upgrade (Automatic FPD Upgrade Only)” as that is the recommended and the easiest way.
    Steps are:
    The command is present “upgrade fpd auto” in the running-config by default.
    Have the Cisco IOS image in disk2:
    Download the FPD image package to disk2: flash disk
    Reboot the router using the new Cisco IOS release.
    Hope this helps
    Thanks
    Syed

  • Ipad 2 Wifi issues after upgrading to ios 7

    I live in a small house, 750 sq ft area (30 x 22). Ipad wifi was working fine in all the rooms before upgrading its iOS to 7. After ipad2 iOS was upgraded to iOS 7, wifi now works in the room where the Wifi router is located. But does not receive Wifi signal in any other room. I tired everything that has been suggested in the forum - like changing the router settings (channel, security etc),playing with ipad2's wifi, etc. etc. But to no avail!
    Clearly the bug in iOS 7 has caused this issue! How does one log this issue with Apple tech support team so they can rectify this issue in iOS 7 patch? Also, please let me know if I should be trying anything else. Thanks!

    I have exactlythe same issue. Have had ever since the upgrade to iOS 7. It's nothing to do with the router. It has to be a bug in iOS 7. Question is, would upgrading to iOS 8 help at all???  Anyone done this.??  I used to love my iPad and it was never out of my hand. Now I just hate it and use my Kindle Fire all the time instead. I used to pick up wiif signals across the street. Now I have to be sitting on a router to connect.

  • WIFI connection issue: After upgrading to Yosemite, I lose my connect in SOAS, university of London. Overtime, it rejects me as Authentication fails in this network. Even the school technicianer cannot fix. I wonder how to downgrade or any solution?

    After upgrading to Yosemite, I lose my connect in SOAS, university of London. Overtime, it rejects me as Authentication fails in this network. Even the school technicianer cannot fix. I wonder how to downgrade or any solution?  I never encounter this issue with Mavericks or the one before.

    I also have the internet diagnostic report, but it is nonsense to me to read it.

  • WiFi Internet connectivity problems after upgrade to 10.8.4

    After upgrading to MacOS 10.8.4 I am facing regular interruptions to my WiFi internet connectivity. Periodically the internet connectivity is lost and the only way to fix the problem is to turn WiFi off and on again. This happens frequently when I am downloading files at using big bandwidth (more than 1.5-2 MB/s). If I use assist me on the Network preferences tab, it displays an ISP error when the connectivity is down, however I am certain that I do nota have any kind of ISP or router issue since at the same time I have WiFi internet connectivity from my iPad mini, iPhone 4S and Samsung Galaxy S3. Therefore it should be a 10.8.4 issue

  • Yahoo mail sync issue after upgrade to iOS 5

    After i have upgraded to iOS 5 my emails from Yahoo are a month off.
    Only the emails from a month before are synchronized. As an example, today 10/24 I can see the emails from until 9/13.
    Any ideas on how to fix this?

    Ok, thanks everyone's experience sharing with each other. after I try so many time with my bro for this issue, finally we got solution to solve this issue.
    I'm using iPhone 4 and my bro is using iPod touch 4th Generation, we both upgrade to iOS 5,
    then I was thinking that when I do Facetime setting, there is a selection that you can use your Apple ID as your Facetime account, so I changed my Facetime account with Apple ID, the default setting is using your phone number. then its works!!  now I can use Facetime with my bro in airplane mode.
    I guess before I upgrade iOS 5, iOS 4 allow Facetime auto detect to use phone number(if airplane mode is off) or use Apple ID, which your email address to connect to another user, but iOS 5 not allow it or disable auto detect, (I just guess). 
    anyway now I only use Apple ID as my Facetime account, then I can use Facetime under airplane mode. hope it help you guys.

  • Connection issues after upgrade to Mountain Lion

    Very strange internet connection problem here after upgrade to Mountain Lion.
    I just upgraded MacBook (early 2009) to Mountain Lion. After upgrade, I'm having problems connecting to certain websites (ESPN, CNN, etc.), and I can't connect to the computer using LogMeIn.
    BUT, I do have an internet connection. Skype works, Messages works, email works, some websites work. I tested using speedtest.net and it shows good download speed, but the upload speed is so slow that it can't even perform the test. A Windows PC on the same network works fine.
    Next, I tested the MacBook on another wi-fi network at a coffee house, and everything works fine there!
    So it might appear to be something wrong with the router? I have an Cisco (Linksys) E3200 and have upgraded to the latest firmware (1.0.4). But still doesn't work.
    The firewall in Mountain Lion is turned off, and I temporarily turned off the firewall on the router and that didn't help, so doesn't appear to be any sort of firewall issue. I've never heard of an operating system being incompatible with a specific router anyway.
    Can anyone thing of any setting or something in Mountain Lion that would causing internet connection problems with a specific router?

    I don't know if this will 'fix' your problem, but have you tried the 10.8.5 Supplemental Update -> http://support.apple.com/kb/DL1686?

  • Signal issues after upgrading to ios 6.1.2

    ever since i've upgraded to ios 6.1.2 have had problems with my signals, hv never seen all bars; 2 at most. hv drop calls all the time. it;s irritating . tried evry thing like network resets, turning off/on 3g and lots of stuff suggested in other threads bt in vain . happened once before in one of the ios 5.something series bt ws fixed on the next ios upgrade. apple needs 2 fix this soon and launch the next update .once fixed i dnt think i'l eaisly try experimenting with ios updates.

    Exactly the same as me. Updated now can not get FaceTime to work. Just hangs on the connecting page then loses connection after several seconds.
    Friends calling me does the same thing.
    It is not our router, I can download and upload data quickly without any problem.
    Who quality controls IPads? Seems lots of mike and connection problems with Talktime at the moment. Apple must be embarrassed.

  • Logic Remote connectivity issues after updating to iOS 8 (solved!)

    Has anyone else has been experiencing connectivity issues with Logic Remote after updating to iOS 8?
    After updating to iOS 8 I could no longer connect so I sent a feedback report to Apple and got a response that cleared up my problem immediately:
    Navigate to the following directory on your desktop system running GarageBand:
    ~/Library/Containers/com.apple.garageband10/Data/Library/Preferences/
    You can quickly navigate there using the “Go” menu in Finder -> Go To Folder (shift-command-G), then copy this path:
    ~/Library/Containers/com.apple.garageband10/Data/Library/Preferences/
    In the Preferences folder should be a file named "com.apple.garageband10.cs”.
    Make sure GarageBand is not running and delete the  "com.apple.garageband10.cs” file.
    Relaunch GarageBand and see if you should now be able to connect.
    The same can be done for Logic by navigating to:
    ~/Library/Preferences/
    And deleting "com.apple.logic.pro.cs" and restarting Logic.
    Note that doing this will fix Logic Remote connectivity issues (and possibly other problems with latency and mixer functionality)  but will also delete any other Controller settings that you've configured with Logic, if you happen to be using another controller of some sort.

    Thanks very much!  This solved my connection problem.
