iPhone 6 internet problems (not just WiFi)

I was able to identify and replicate one trigger for the bug. For me it was an obsolete email app (Secure Gmail, Apps Gone Bananas). I use 2 different email apps to segregate my accounts, if an email was pushed to Secure Gmail when the phone was in sleep mode for some time (>2hrs?, it generally happened overnight) then all subsequent connectivity was lost until reboot. I deleted Secure Gmail and replaced it with a current app (CloudMagic), and so far so good. I did have one more freeze that may correlate with Hotspot VPN, but I haven't replicated it yet.

Originally, I had added an enterprise Exchange account to my phone with ActiveSync enabled (as well as an Outlook.com account), and almost regularly every 4 or 5 days my phone would lose all data (although it was never apparent until I tried to open a web page or check email).

I've experienced this bug since iOS 8 was released on my iPhone 5S. I had tried everything others have mentioned in the thread, including wiping settings and resetting everything to default (with no restore) and nothing worked. I also have a colleague who had the same problem as well (he's on Sprint, I'm on Verizon).

What ended up "solving" the issue for me (and my colleague) was turning off push email for all of my accounts (except for iCloud - I left it on push). After I did that, my phone would not reboot like it had before and hasn't since January. However, a month or so ago I got curious to see if the newer version of iOS fixed the issue so I re-enabled the push email...and sure enough the problem came right back. I've reported what I've found to Apple, but that was over 4 months ago.

YMMV, but that's what "fixed" it for me. Whether there's an issue on the stack's end or maybe in some background process, I'm not sure. There's definitely an issue here though that hasn't been truly resolved.

Got my iPhone 6 in early March, began having this issue 3 wks ago - shows a cellular signal (Sprint 3G or LTE), but no data will come through. This began happening before I updated to 8.3, I thought the update would fix it. Not so. Works fine on wifi, phone call are fine. Initially doing a reset would make it work for a short time, also doing a carrier update it would work for a short time. I've been to the Genius Bar, they recommended replacing the phone. I did. Same problem. A Genius Bar employee thought perhaps the issue was with the software back-up (I restored from the cloud when I got the replacement phone), so I started from scratch - did not restore from the cloud. Same problem. I have yet to get back to the Apple store. Saw a comment somewhere that mentioned they thought the issue was when the phone would transition from 3G to LTE networks, and vice versa. I have had luck restoring the cellular data connection by turning airplane mode on and then off again, but as soon as I leave wherever I'm at (ie, leave work to go home) the connection will be gone again. And that trick hasn't worked today at all.

Finally resolved my problem--it was on my sprint account! I went to sprint corporate store (not one of the ones run by another company), they took service off my phone then switched it back on. It works!

I just recently got my iPhone 6 (about a week and a half ago) and just started having these same problems yesterday. I've tried resetting my phone as well as settings and iCloud and nothing helps. It doesn't occur over a few hours either, it happens every time I reset the phone. It works for a minute or so and then goes out again. Clearly the new software does not provide a fix for this problem. Has anyone found something new to help with this problem?

Same problem exactly if I reboot its fine for a few hours.

I'm about ready to dump Apple.

This has been going on for over a year and whenever I take the phone in they can not figure it out and have not been helpful at all

I don't know if this has been said already, I apologize if it's already been suggeste, but I had the exact same problem and it was really ******* me off in the extreme. After reading this thread it occurred to me to try shutting off the LTE function in the cellular section of setting. Since I've done that I havent had the "cannot connect to the Internet" issue after coming off of a wifi network.

Whether that's actually the problem, or it's just coincidental, it completely work for me and it seems like there are hundreds of other people out there with the same problem so I thought I would let you guys know what helped me out.

hopefully it will work for some of you.

As an aside, does anybody know what exactly the LTE network is all about? Is it just supposed to be faster?

i have this problem to and i know it only for my iphone because my 2 brothers phone works and my moms phone works to ive had 4 replacment phones already! i really wish steve jobs never died because most of us probaly wouldent have this problem! im most likely switching tosamsung in the next couple of days! very very frustrated😠

Try going to settings and resetting all network settings. If that doesn't work, reset the gateway. Contact your local retailer from where you bought the device or your local apple store if the issue persists. 🙂

I fixed mine by resetting all settings

I was having a problem in the morning where my wifi would connect but will not work. This happens when I use data as well. I could also run a wifi test and get the results (12 mb download, 2mb upload) but couldn't get on anything else that requires wifi connectivity such as google chrome. After resetting the network settings, nothing happened and I decided to do a full factory reset (erase all content and settings). This, however, requires internet connectivity because I was forced to enter my iCloud password to remove my iPhone from the account, so that method would not work. I also did a couple hard resets and just plain shutting down and turning back on. These methods didn't work so I attempted to reset all settings to see what will happen. After the reset was completed, wifi connectivity began working again as well as data connectivity immediately.

Model: IPhone 6s Plus 16GB

I hope this works to everyone who reads this because having connected to wifi and data and not having actual connection can be very frustrating.

I have the same problem as you and the guy who created topic. I dont know is it a hardware issue or sw ? Only happens when phone comes from sleep. I tried even factory reset with set up as a new iphone and problem still persist.

After restarting my iPhone, turning it on Airplane mode, turning the wifi on and off, and sleeping through the night -
I finally turned off the VPN on my phone. The data and wifi instantly started working again. A bit annoyed that this is the issue. I've used this VPN for two years and sometimes had minor with connecting to the internet, but nothing like this. A quick google search of "Adblock internet connectivity issues" shows that I'm not the only one who has experienced this issue.

its a definite IOS bug, both my home and office Wifi fluctuate and once that happens, iphones internet services are stuck, neither wifi nor 4G works...

only soln is to restart....restarting works without any failure...hope apple guys notice...i am stuck with iphone just because of its support for "USB mass storage" which android has dropped.

Have any of you tried changing your router's to operate on a different channel?

Update:

on my 2nd replacement phone (3rd overall) and still have same problem!

Hi Robert.

I have not experienced the problem since the one time, but to answer your question, I am not using any VPN and btw am using Verizon as a service provider.
