My wife's verizon GS4 has CM11, last M build, I think M12?... Anyways, it has a nasty habit of losing its mobile data connection periodically. She has to reboot the phone to restore data access, and she may not notice for hours, when she hasn't gotten any emails or hangouts chats in a while. As soon as she comes home and connects to the wifi, everything comes through again.
Also, her wifi gets stuck sometimes, where it will just lose connection, and trying to cycle wifi just results in it getting stuck on "turning wifi on..." or "turning wifi off...". Again, the only remedy is a reboot.
Does anybody know of a fix for this? Should I try to get her phone flashed over to a GPE rom? Should I move to a lollipop GPE rom if it exists? If so, is there a "best" way of backing up / flashing / restoring outside of titanium backup everything?

I have a limited data plan so I keep my data turned off most of the day. The problem I have is each time I turn the phone back on the data turns back on also. It did this with the stock rom so i even tried the Omega rom and there is no difference.
If i toggle the data off shouldn't it stay off until i turn it back on? Never had this problem with any other phone i have owned.
Would greatly appreciate it if somweone could tell me what i might be overlooking.
Hello guys,
my problem relates to activating WiFi and/or mobile data on my phone.
First of all WiFi:
I'm used to enable it via status bar. But when clicked nothing happens but the symbol changing. When entering the WiFi settings through systemsettings WiFi is disabled. Enabling it there works fine, but is not what I would expect.
Before it worked fine.
Next problem.
When WiFi is enabled (it's most of the time when I'm at home) I disable mobile data (no matter if 2g or 3g). It runs over night till i leave home. Now when I want to enable mobile data, nothing happens. Even an analog work around described like above wouldn't work. The only way to get it working is to reboot the phone..
Any idea how to solve it?
My specs:
Samsung Galaxy S2 (int)
Kernel: Kernel_Siyah-Dorimanx-V9.10-[10-51]-[21-03]-JB-CM-AOKP-SGII-PWR-CORE
ROM: cm-10.1-20130321-NIGHTLY-i9100
Modem: I9100XXLS8
My fiancée and I got the same problem with the mobile data. I updated her phone with the latest nightly to be sure it's nothing that may have already been solved, so she got cm-10.1-20130320 nightly, I have yet to update from cm10, still running cm-10-20121209 nightly.
After turning on wifi or turning off mobile data (mobile data connection has to be interrupted) and leaving it off for a longer period of time, turning mobile data on again does not work. The button changes, the phone also reflects this in the data usage menu, the button is set to on, but nothing happens. Rebooting the phone then solves the problem, Mobile data can be turned on and off again for some time but leaving it turned off again will result in the same error. I hope this is somehow comprehensible.
Any idea what we can do about it?
I don't use CM anymore, but when I used to run CM9 that happened to me occasionally. Restoring a backup or reflashing the rom & kernel directly over the top of the current instal without wiping (if you're using another kernel) was the only thing that fixed it for me. You may find that reflashing the rom/kernel doesn't work; if it doesn't, I'd do a clean install (wipe/etc; tho I never had to do this to fix this problem).
Hello,
Recently, I've been losing data connection randomly. Calls/sms work fine, but I have no data connection. I've found that this typically happens when I leave my home wi-fi network, and then I have no data connection. This also happens randomly, data is working normally, then an hour later, I lose data connection. When this happens, the signal bar is still blue, not grey. Usually, after turning airplane mode on and off, it fixes the problem.
Does anyone know why this is happening and is there a fix to this? I've done a nv_rebuild before, and that may be my last resort.
I am rooted, running Dubbsy's 4.2.2 GE ROM. I would post this question on that thread, but I do not meet the minimum post requirement.
Thanks for reading, and let me know what you guys think!
I have a bizarre problem that just started happening, I can't connect to mobile network after using a wifi connection for some time. No matter what I do, the S6 edge won't connect.
I've tried switching mobile connection on and off, restarting the phone, turning the phone off and back on, switching sim cards with another phone (the other phone immediately gets connection), switching airplane mode on/off. I've gone to Samsung and my mobile provider and they have both blamed each other (of course, right?). The most frustrating part is that this happens about 50-75% of the time with my home and office wifi, and almost never with anyone else's wifi (for example trying it in the Samsung store). It will sometimes get a connection 10-15 minutes later, sometimes it takes several hours.
Samsung service has offered to take the phone in to 'review and test' but they need to do a full wipe and it will most likely take several days of testing. Knowing that the problem is almost impossible to replicate outside of my home and office, and the issue goes away by the time a service tech will ever see the phone, and the struggle to back up and restore my apps without root, I'm not sure what to do right now. Temporarily I have turned off wifi and just use mobile connection, but I'll hit my monthly data cap really soon.
This started happening 2 weeks after AOE4, just upgraded to AOE8 and it still happens. My phone is SM-G9250 with Taiwan ROM.
Screenshots attached to show I have good signal strength but not data connection, and the SIM in another phone having a connection (Zenfone 5 with lollipop).

Did you try wiping the cache?
I thought the cache is wiped whenever you do OTA update?
I'll do it manually again right now and see if it helps. Thanks for the tip.

I have the same issue! Very annoying, and miss phone calls all the time or am unable to make them because of this...
Will try the cache wipe
Wiped the system cache from Boot, problem still there.
I also wiped the cache for all apps.
I also tried the phone in safe mode and has the same problem.
Sent from my SM-G9250 using XDA Free mobile app
So the only work around I can find is to go into settings:
1.) 'Mobile Networks'
2.) 'Network mode'
3.) Switch to 3g/2g (I don't have 4G right now, have to pay extra for it)
4.) go to 'Network operators'
5.) 'Search Networks'
6.) choose my network provider
Now the phone works just like it always did, smoothly switch between wifi and 3G and H/H+
I'm not sure what changed as I have never had 4G since it costs me extra.
[Q] [pseudo-solved] Device occasionally loses Internet connection for WiFi & cellular
The Problem:
I recently upgraded to the Motorola Moto X Pure Edition and have got almost everything running smoothly except for one thing - every so often, (between 2 and 8 days) the device will completely lose its Internet connection for no apparent reason, displaying the little exclamation point next to either the WiFi or cellular signal strength indicators. It usually happens after transitioning between WiFi and cellular (leaving home, arriving home, etc.).
Once the device enters this state, no amount of toggling WiFi, data, or flight mode will allow the problem to be resolved. The device will simply refuse to cooperate with any type of Internet connection at all, even though it still has an IP address, as reported by the ifconfig command in the terminal. No addresses, local or otherwise, can be pinged.
Rebooting the device always brings it back. Clearing the cache and dalvik cache seems to make it last a bit longer, but this has yet to be confirmed.
Troubleshooting efforts and device configuration notes:
A web search turned up nothing at all, although two other people in the original thread on the Moto X Pure Edition Q&A forums revealed that I'm not the only one with the problem. My device is running the stock, Android M Rom, (rooted) but others have reported the same issue with a non-Motorola Android N ROM as well as on the stock un-rooted Rom.
This leads me to believe that the issue isn't Rom-specific, and may not even be device specific. With all this in mind, does anybody have any good tips for troubleshooting this? Any ideas for what could be causing it or how to fix it?
Thanks!
TL;DR? Device loses all Internet connectivity on all connections, usually after transitioning between Cellular & WiFi, on stock-rooted Rom, problem reported on stock and non-Motorola Roms as well. Software or settings conflict suspected.
Update: Hard reset; problem solved. No cause was ever uncovered. See post 7 for all the details.
Internet loss breakage Logcat
Here's the Logcat, if that helps. I tried getting a complete one, but had to cut it off after close to 45 minutes, so there still should be plenty there to go off of.
Any ideas?
Anybody? Any ideas at all? I'll even accept shots in the dark at this point. Made it a record-breaking <9 days, but the problem came back again, even with "Cellular data always active" switched off.
anything? anyone?
Ran into the issue again today, even having left WiFi manually turned off. Any ideas on this? I'll even take shots in the dark. Anything short of hard resetting and reinstalling apps & reinstating settings one-by-one.
Internet dropped out again...
Had the issue again today, but this time caught it "as-it-happens" (as I have only once before). This time, I woke the phone up and saw the exclamation point over the WiFi signal strength indicator, but was still able to use the LTE data connection. Resetting the cellular radio put a stop to that as well.
Any ideas at all? I'm taking complete and total shots in the dark at this point too.
Still losing Internet connection on WiFi, then cellular as well
Same deal again today. Any ideas at all? Anything I can do short of pulling the plug and hard resetting?
Hard reset; fixed
Well, I ultimately pulled the trigger and hard reset the device. The problem appears to have permanently vanished, but we will unfortunately never know its cause.
