After briefly losing service, iPhone will fail to connect to the cellular network until you restart

When my iPhone lose service for any period of time, as when he drives through an area that is not covered or go inside a building, unit reverts to the cellular network once he's back in the range. I tried to switch the plane made to make additional research; It does not work. I tried to reset network settings. It doesn't work and now I have to re - enter the password for each network wifi (disappointment).

The fix, however, if I turn the unit completely off and the power supply back on. Only to reappear again the next time that I lose the service.

What in the world is the cause and what can do about it?

Things to note: MRI comes back fine. Issue JUST started this week. Device has been restored there is from a backup about 3 weeks because it is a replacement for one that I destroyed.

I can confirm the exact behavior that you are experiencing.

My iPhone brand new T-Mobile SE (1 week) did not have this problem on iOS 9.3.5. He found his connection to my mobile operator without any problem before the iOS 10 update.

I also tried all the things (airplane, network reset mode, etc.) that you tried. Will not fix it. The only thing coming back my cellular service is to power cycle the phone.

It's a real problem for me as I work in a story 72 building (no service in the elevator) and I have unfortunately to enter and leave the building a certain number of times per day.

You have not specified what iPhone model and what version of the OS. Can you clarify?

Thank you

  • iPhone will not stay connected to the internet?

    * Posted on MacRumors forums but no answers *.

    So basically since a few days my phone sometimes don't remain not connected to the internet network of BT-Hub3. I connect to it and then sometimes, it will stay connected for a minute for a few seconds and then disconnect. When I go to the wifi thing it seems available to connect to. After a couple of times that to happen, it will say wrong password (this is the password) and disconnect me and then I have to type the password. Repeat to infinity. It's honestly so frustrating.

    Sometimes it will stay and be fine but his is happened twice in the last few days and never happened before with any phone I've had.

    I try my phone with my BT-Hub4 internet network and it will stay connected. The only problem with this is that the internet is further (bottom), so has a low connection that does not charge anything unless I lean on my bed.

    Initially, I assumed my internet pick, but I'm typing this I am connected to the network BT-Hub3 without disconnect him, even once.

    I had the phone for a year and 2 months (previous owner had since October/November/December in the year of release) and recently got a replacement of the unofficial battery if this of any help. I also still have my phone on the low power mode. The phone always properly connect to the BT-Hub3 network even with unofficial battery and low power however mode.

    I had several other problems with the phone (camera, apps download not heat no reason apparent, random battery drains despite the new battery in just 3 months and has the same problem with the battery, slow Touch ID that apparently is not normal), which most recently happened.

    I had all the settings to reset a week or two ago but surely if who messed with my settings internet I would have had the internet issue earlier? Not sure if I should try to reset the network settings. I hate this and only do if I need to.

    One last note, I have the latest version of iOS so ignore saying his 9.3.2 on

    Hi pinkdolphins0400,

    Thanks for posting in the communities of Support from Apple! I understand that you are having problems with your iPhone does not stay connected to your internet connection at home. I use my home Wi - Fi network to stay connected, so I use all the cell data, if I can understand wanting to make sure that you are able to stay in touch. I am pleased to provide you with a few suggestions for you.

    The first thing I recommend you do is follow the steps described in the following article. It seems that you have already experienced some of these steps, but I want to be sure that you have covered everything.

    If your iPhone, iPad or iPod touch connects to a Wi - Fi network

    Since you mentioned that your iPhone will stay connected to your network to another, you can take a look at the network settings for the one that you are having problems staying connected to. Article below provides information about network configurations suggested for Apple devices. You can also check with the manufacturer for your BT 3 - Hub see if there are updates that must be performed. This can cause problems with disconnects.

    Recommended settings for the WiFi routers and access points

    For other problems you mentioned (apps do not download, camera, battery draining, contact ID, etc.) reset settings was a big step in troubleshooting to try. If these things are always happening, I recommend making a backup of your iPhone and then restore it via iTunes. The backup will ensure that your data is saved. When you perform the restore via iTunes, you'll want to set up as a new device (temporarily), and then test it. Once you test, you can try to restore your backup. You can find all of the information below, you will need.

  • HP Officejet will not be connected to the wireless network?

    I have a HP Officejet 6500 wireless which will remain not connected to the network over a half hour or so, max.  My wife runs a laptop XP Pro and I have a Macbook Pro with Snow Leopard.  She NEVER problems printing, but my computer is always looking for the printer unless I re - connect via the wirelss Wizard.  I also use a Westell 327W Versalink router/modem and I have connected my Mac via Bonjour, if that helps.  Any ideas out there?  I even reinstalled the router right next to the printer thinking that may be the issue.  He STILL abandons the connection, but it's funny that my wife's computer is not...

    OK, let's assume that your Mac software is correct for now.  Its probably a good assumption.

    We will define an IP address from the printer.  This can help find the network when he wakes fashion 'sleep':

    We will set an IP address of the printer:

    -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
    -Enter the IP address in a browser to reveal the internal settings of the printer.
    -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
    -On this screen, you want to set a manual IP address. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). In your case, is that 192.168.1.15 to 192.168.1.47 can use 192.168.1.50
    -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
    -Let the gateway and DNS white. Click 'apply '.

    Now, stop the router and printer, start the router, wait, and then start printing.

    After that, you will have to redo 'Add printer' using the new IP address.

  • Windows Media Center extender on my XBOX works initially, but not after reboot of my XBOX. Error: Failed to connect to the Xbox 360 could not connect to the windows Media Center computer.

    It's VERY odd and very annoying!

    I set up my laptop next to my Xbox 360 with an Ethernet cable directly connecting the laptop to the XBOX, and the laptop is on our wireless network. The XBOX has access to the internet (shared through the laptop), and when I test the PC connection and the connection XBOX Live sound fine to all.

    So I'll try to set up Windows Media Center, it works great! I "Add Extender", put the code to 8 digits. It passes through the installation, all works, no problems and WMC opens on the XBOX, I can go into my library, watch movies etc... works great!

    However! As soon as I turn my XBOX off and back on, it will fail to connect to the WMC.

    He says his 'find Windows Media Center PC' which seems to work fine, it goes to the ' Windows Media Center loading screen "contact...". ", and after about 10 seconds, I get an error"failed to connect the Xbox 360 could not connect to windows Media Center PC. Make sure that the PC is turned on and connected to the network.

    I tried to configure the Extender repeatedly, whenever it works fine until I restart the XBOX... :/ - and its strange cause I still the internet connection (shared through the laptop) after turning on the XBOX, its really JUST Media Center which is screwing around.

    She continues to keep trying to connect then repeatedly fails.

    If I wanted to, I could re-configuration the WMC Extender EVERY TIME turn off the Xbox, which works the first time without fault, but that's all just stupid.

    I can't really understand what is happening here... any help would be appreciated.

    Several times after that I opened Google it does not connect to the internet. Has worked for a long time, and now it will not. Sometimes it opens if you "Refresh" sometimes not.  Help, please. It has been stable over the years and now it will not work. I get no help when I diagnoise of problems, but I never. It has been checked and rechecked. PitStop does not even recognize a problem. I could change the homepage, but I prefer to use Google if it works. Frustrating.

    You may need to update your toolbar, google has made some changes just about everything and possibly that the page is not where it used to be.

  • Mandatory to install Win updates a system that will never be connected to the Net or exposed to any bad guys?

    I realize that I can introduce potentially bad via a disk, a flash drive. But what happens if I was ever going to introduce something foreign to this particular PC?

  • WRT54G v.5 will remain not connected to the new laptop / Windows 7 Premium

    WRT54G v.5 will remain not connected to the new laptop / Windows 7 Premium. It works continuously with a cycle detection, connection, loss of connection; detection, connection, loss of connection, etc... The router works through this cycle, basically acting as if I disconnected and then reconnected to the power to reset, it disrupts my Internet connection to my Wired iMac and wireless, another office to the floor. Paid for Linksys support today and through remote access, he put up a new network on my desktop (iMac). After finishing, the problem still exists. When I told him that the problem had not been corrected, he said just wait an hour or two and it should work itself. She, of course, did not himself. Any ideas out there?

    Nevermind - I seem to have solved the problem with a simple firmware. Funny how the Linksys technician support don't think to ask what version of the router I have or suggest that I should try to upgrade firmware first. However, he is quite good at trying to upsell me for a new router instead of trying to help me solve the problem I had. It makes me want to go buy Netgear next time, thanks a lot!
