Blue screen iPhone 5S reboots several times daily only at work

I experience blue screen of death only at work but I'm connecting to a broadband Internet Wi-Fi network even while I'm at work.  I'm not connecting to the work wi-fi networks (used 'forget this network').
Simply, the presence of these networks causes my iPhone 5S to reboot 5 to 10 times a day.
This issue does NOT occur at home using wi-fi or anywhere else with wi-fi but it happens each and every day while at work.
The work Wi-Fi infrastructure is Cisco (again, I'm not even connecting to those).
I have 7.0.4 installed on iPhone 5S (it's slate gray, not sure if this occurs with other colors... a little humor).
If I turn off Wi-Fi while at work, the iPhone does NOT reboot.
At home, no issues with Wi-Fi but I have to remember to turn it on when I get home each day.
Issue did NOT happen on iPhone 5 with iOS 7.  Issue has occured on iPhone 5S with each version of iOS 7 since the day I received the iPhone 5S.

Jota,
What brand/model of wifi router do you use at home?  At work (where I am experiencing this issue) we have Cisco wifi access points and we have one Netgear WNDR450 (N900) router.  The Netgear router is connected to a Cable modem circuit for commercial broadband/Internet access and the Cisco routers are connected to our internal company infrastructure.  The Netgear router uses the 5GHz 802.11n whereas the Cisco's are 2.4GHz (also 802.11n). 
With this configuration, the iPhone reboots (blue screen) several times daily.  This only occurs in this environment.
How is your environment set up?

    Hi Darr4425,
    That's not good! We definitely want your device to work properly at all times. What email application are you attempting to open? When did the issue start? Do you receive an error message when the application force closes?
    Thanks,

  • I opened my MacBook Pro to a dark gray/black screen. Rebooted several times to no success.  Pressed the "sunrise" button to no success.  Computer only 14 months old.  Any suggestions to get this puppy working?

    Do you have AppleCare? Even if you don't, take to the Apple store and tell them what happened. They should help even though it's a few months out of warranty. You might have to talk to a manager or different higher up.

  • Why does my Ipad keep going black and then back to the apple logo.  It eventually goes to the start page but then blacks out again.  I have already rebooted several times with no luck!!

    Why does my Ipad 2 keep going black ahd back to the apple logo.  It eventually goes to the home screen and allows me to try something else but after about 30 seconds it happens again.  I have already rebooted several times? 

    Make Sure iOS is updated to the latest version
    Reboot the device by pressing and holding down the home and sleep/wake buttons (power) at the same time until the apple logo appears on the screen, then let go.
    If that doesn't work then reset the device by going to settings/general/reset/reset all settings

  • My new iPhone 4S restarts several times a day...

    My new iPhone 4S restarts several times a day...
    I have iOS 6...
    How can it be fixed?

    Same issue here.  I'll be using the phone and the screen will all of a sudden go completely dark to the point where I can't see anything.  But the phone still works as I can hear the click sound when I click the sleep button or slide the bar at the bottom.  But the screen is completely blacked out.  I have the shut the phone off and turn it back on to solve the issue.  This happens at least twice a day.  What is the solution?

  • I receive a not connected to the internet message several times daily on my iMac connected via airport to a time capsule which accesses the internet via cable modem.. When I input my password to enter network preferences, the connection re-establishes.

    I receive a "not connected to the internet message" several times daily on my iMac connected via airport to a time capsule which accesses the internet via a cable modem. Software/firmware is up to date on the iMac (OSX 10.6.8)  and Tme Capsule(7.5.2). Browser is Safari 5.1.
    When I input my password at the prompt to enter network preferences, all the lights go green (ie... ethernet, ISP etc.) and the connection re-establishes immediately and states "the connection appears to be working normally".
    It more of a nuisance than anything and seems to have started ocurring over the past couple of months. I also have a windows XP box also connected to the same cable modem that I never have internet connectivity issues with. I've verified all the physical aspects of the connections and can't see any evidence of any actual drops in the modem logs. I suspect it is just an intermittent communication loss between the Imac and the Time Capsule, but I am not very familiar with Mac equipment yet.
    Just wondering if anyone has experienced a similar problem and what you did (if anything) to resolve it?
    Thanks.

    The AirPort Express will connect to your existing wireless network if the network is using WPA2 Personal or WPA/WPA2 Personal wireless security settings.
    So, it can join the network as a client and then provide an Ethernet signal to your Time Capsule.
    Be sure to configure the Time Capsule to operate in Bridge Mode so that it will be operating on the same network.

  • Windows 7 desktop unresponsive, must reboot several times.

    I am having this issue on a number of machine in our environment where after a boot, the desktop becomes unresponsive.  I cannot open Windows Explorer, IE, control panel, nothing opens.  When I try to restart, the restart option from the Stat Menu
    does not show up and I have to Shut Down.  I think the Server service is what's failing to start at boot but I can't even get in to view the running services.  The Event Log is also seeming to fail to start so there is not log of the errors taking
    place.  This is very frustrating for my users who have to reboot several times before the computer will start working again.  Please help.

    Hi,
    So here we are in a domain environment? If yes, please verify if any group policy settings would casuing this problem;
    Meanwhile, please boot in safe mode to see if this issue was caused by any 3rd party applications, also take a check to see if there is any conflicts between the devices and the drivers:
    Start your computer in safe mode
    Hope this may help
    Best regards
    Michael

  • After updating my ipad mini retina to 8.1.2, my device experiences blue screen of death at random times.

    After updating my ipad mini retina to 8.1.2, my device experiences blue screen of death at random times. It is so annoying plus there are applications that keeps on crashing such as brother in arms by gameloft so i have no choice but to reinstall it all over again.. But after quite some time the apps will crash again.. Argh it's a cycle. so annoying..

    Hi  It sounds like a bug. Go to settings iCloud backup over your WiFi Then Restore back to Factory Settings. After Restore use same Apple ID then you will get all your apps & data back. Do Restore over your WiFi. Since ios 7 Almost everything can be done over WiFi you don't need to use your PC. Cheers Brian

  • IPhone 4s reboots many times when trying to sync with iTunes

    iPhone 4s reboots many times when trying to sync with iTunes.
    Since IOS 8, my iPhone 4s reboots many times when trying to sync with iTunes on my Mac. It will start running the backup and reboot, it will reboot many times when updating packages. It can take 12 hours to finish a sync with the mac. The phone gets hot during this. I keep deleting more and more pictures and apps, hoping that maybe it doesn't have enough space, but iTunes shows I have 4.9 Gbytes free, which I think should be enough.  I am on IOS 8.0.2, I thought maybe I would try to upgrade to the latest IOS today, but I am worried that I will end up with a non working phone.
    Is anyone else having these problems?
    Ed

    Well thats Od... I have never experienced that problem.. Maybe you should try to backup your phone and then wipe it by going to Settings<General<Reset

    every time I try to uninstall firefox a window pops up and says that a previous upgrade was unsuccessful and I need to reboot. I have rebooted several times, I have downloaded a "fresh version" and installed it. It won't uninstall. Someone please help!!

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
    ''(If you're using an added theme, switch to the Default theme.)''
    If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the '''Restart with Add-ons Disabled...''' menu item:<br>
    [[Image:FirefoxSafeMode|width=520]]<br><br>
    If Firefox is not running, you can start Firefox in Safe Mode as follows:
    * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac: Hold the '''option''' key while starting Firefox.
    * On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    [[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
    ''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    When you figure out what's causing your issues, please let us know. It might help others with the same problem.
    Thank you.

    Just had this same problem. Based on other suggestions I found on the web, went to C:\Program Files\Mozilla Firefox and deleted all files that ended with upgrade and/or delete. Then I was able to uninstall Firefox and then reinstalled. Hope this helps!

    I downgraded the Time Capsule to 7.6.1
    I've had similar issues using a 4th Gen running 7.6.3 with OS 10.6.8, but have stuck with it because the performance with 7.6.1 was actually worse in my situation. Your own setup may well perform differently, but you might want to monitor your TC’s behavior closely for at least a while. Or just downgrade to 7.5.2, as LaPastenague suggested. In my case, downgrading to 7.6.1 — I have a recent 4th Gen, which won’t accept any earlier basebinary file — caused serious disk spin issues, a not uncommon problem to judge from the many complaints about it appearing on this list.
    Apple: improve your regression testing, please!
    My question: Does anyone have a sense, based perhaps on Apple‘s past practice, of whether it is at all likely that there will be future firmware upgrades for pre-802.11ac TCs — or should anyone currently using these legacy devices just abandon all hope at this point?
