Mobile data not working after WiFi disconnect [T-Mobile] - OnePlus X Q&A, Help & Troubleshooting

Hey everyone,
I did a clean flash of OOS 2.2.1 a week ago. Now every time I go out or disconnect from WiFi, the LTE triangle always shows an "!" and I have no data. It's kind of a pain because I move around a lot and I have to keep toggling data or rebooting.
Is anybody else having this issue? I tried flashing a new ROM (CM13) but the issue still persists. My APN settings are correct, so it's definitely not that.

I've actually experienced this too on CM13.

I was about to create a thread with just this issue. I thought I had experienced this before CM13 updates, but not sure now.
Basically, when wifi connection is off or lost, mobile data will not work.
I have yet to actually work out the permutations of what causes the issue and the actual fix but essentially it goes like this:
Apply new ROM with clean, 'by the book' install.
Wifi works fine.
Disconnect wifi and mobile data doesn't work.
Check settings, all appears OK, but click data off and on again etc
Reboot
Wifi and mobile data work as expected.
Now that's at my home!
Leave house and mobile data doesn't work.
Check settings, all still appears OK, again, switch off/on etc
Reboot
Wifi and mobile data work again fine.
I have not conducted a proper scientific analysis of this, but I am wondering whether it's to do with changing radio towers. Once configured phone is good until new radio tower encountered.
I have just installed a new ROM and fixed the mobile data issue at home. All seems great.
Next time I go out I will see whether I lose mobile data if the radio tower changes.
I have tried about 6 different ROMs and all suffer the same issue.
I have become so frustrated with it that I am even considering changing my phone.

Okay so I fixed it but I'm not sure what initially caused it. When I clean flashed from 2.2.0.X to 2.2.1 via TWRP I started getting the issue.
However, I got it to work by reverting back to 2.2.0.X then updating to 2.2.1 via OTA. No longer having issues with data. Though I haven't flashed any CM13 ROMs so I can't say those work properly.
Not sure what went wrong initially, but it must have something to do with the radio. Hopefully this helps everyone else who is having problems.

[Q] Data Connection bug. How to solve?

The Edge symbol in my Galaxy S2 disappears when the signal is down.
It never reappear when the network signal get back. Even If i change all settings... tried disable/enable "Use packet Data" and other settings...
NO USE! It seemed to be serious and consistent bug.
Hi balavj, maybe a silly question, but are you sure that you are in an area well covered by edge gprs signal?

Signal drops inside a room... when i come out of a room... network signal regains... everything works... data connection symbol does not come back... this is the exact problem... only after reboot... it resolves
Ah I see... Never met these conditions with my phone here, so sorry I can't be of much help.

i am having a similar problem, seems to have happened quite recently for me as previously i had no real issues with it at all.
I keep having to reboot my phone to get a mobile network connection, otherwise the Mobile Network Status shows as connecting all the time...
Very strange
Try other modem, or shove the phone into airplane mode and back again should kick it back onto data.
I have the same problem here...
Tried KE4 (Original), KG7 and KH3 modems e nothing..
Tried many roms too, and nothing, the problem is on all of them...
Data on/off, Airplane mode on/off, nothing gets data working back, only reboot...
Ps.: ROMs tested: Lite'ning, Cognition, Exynos, KE4, KG7.
Kernels: Niphetamine, Jeffrey, Speedmod
SAme here
same here...
Is anyone still experiencing this?
I was having major issues with connectivity, data and calls. I got to the point where i could barely make or receive a call or connect to a mobile data network.
I tried numerous modems and firmware, including original O2 carrier branded firmware, generic firmware and custome ROMs. I found the problem replicating across them all.
I finally settled on Crsikelos ROM (V14) with KE7 modem, however i had previously done a full wipe install of my original O2 firmware (XWKDE i think) and tried a couple of different modems (KH3, KE2 and KE7).
I even tried removing my SD card as i am convinced my sd card is not compatible and is causing issues...
All of a sudden everything started to work again?? I put my SD card back in and left it in, no chance everything was still working. So then i flashed Criskelos Rom and made sure my modem was KE7, that was about a week ago and it's still all good.
TBH i think it may be something to do with O2's network being pants (rather than my SD card )....
Not sure this will help but i thought i'd post my experience for you...
Hope you get it fixed
i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.

[Q] Network Connectivity dropping out

Hi all,
Strange thing occuring with my Streak all of a sudden. I can be using it, or it will be locked and screen off, but when resuming use, my mobile network connection is not working. It's still selected in settings, but no data icon in notification bar, and no connection. Turning the 'data enabled' off and back on sorts it out and all is fine, but I cannot pinpoint why this is happening. No obvious reason that I can see.
Initial thoughts were that the network was playing up (Giffgaff), but I'm not convinced about that since 'rebooting' the network on option fixes things.
The other thing to mention is that it's only started recently after going to a GB rom, then reverting back to stock, but I've flashed the proper way, and the basebands are correct for the rom. Tried different stock roms, and it seems to be happening with them all now.
Could something that isn't part of the stock rom have become corrupted? Is it anything that rooting with Superuser could have caused? Had this phone for over 12 months, and never had this. Baffled

Problemw ith Data after Flashing Roms

Interesting problem that I suddenly have after installing rom. First I have been installing just about every rom has come for the last 6 months. Today I installed latest Carbon ROM from here http://forum.xda-developers.com/showthread.php?t=2310695 today and it installed ok, but upon booting for the first time, it got stuck the setup right at the beginning where I press the language (English). It just sat there and didn't do anything. I tried reinstalled the rom, and it did the same thing.
So I assumed a had a bad download, so I went to restore my daily driver backup rom (Zone sense 4 rom from here http://forum.xda-developers.com/showthread.php?t=2116509). But now I have no mobile data or mobile connection at all. I get a triangle next to the bars and whenever I restart phone I get this message "Global data roman access is allowed. Significantly higher charges may apply". I have never seen that before.
I have tried removing sim, toggling all mobile network options (CDMA, global, roaming, etc.) and I still get no connection at all. Any ideas here? I am on Verizon.

Thanks. I did that and it worked. Any thoughts on how to avoid that in future aosp roms? Did I do something wrong or is it totally random?

Its apparently random. I've had it happen twice, once back non CM10 when it just got RIL going, and a build ago on Carbon.
I'm going through this right now. I rru'd and can connect to 3g and use the data but no texts and when I try to make a call I end up with a Verizon message saying my number is inactive. Everything works fine on my backup phone. So its not a problem with Verizon
Edit... I'm going to ruu again and factory reset before booting because I think I remember seeing that posted at some point

EDIT 2.... re rru'd still having problems it will not make calls and will get 3g data when set to roaming which it seems to be on with the triangle above the signal.
anyone know the Verizon apn's i only have verizon internet in my apn list.
Edit 3 All fixed. i was factory resetting in stock recovery to no avail but a factory reset in sense itself worked

[Q] Data stops working on AOSP roms but works on stock Samsung. Why?

Hi,
After flashing a build of CM11 back in February, I've had problems with the data-connection (2G/3G/H, etc.). It works when starting the phone, but suddenly it just dies. It looks like it's working, but no data seems to be transferred. I have to turn data off for a minute or five, and back on. The it usually works for a while again, until it dies...again..
I've fullwiped (except SDcard and internal SDcard), and tried several modems. Then I went from CM back to Ultima ROM (based on stock Samsung), and used it for a couple of days. Data worked perfectly. Thinking it solved the problem, I tried Omni again, after wiping/formatting data, system, cache and Dalvik. Installed it, data seems to work, but after a few hours, it just dies again.. The signal icon still has the H+ connection, etc, but I can't use it. Just like it's offline.
Any ideas?
Use GSM Network

This is EXACTLY what happened with me. I don't use WCDMA Network now. Use GSM Network (EDGE). I hope it'll get fixed in Android 4.4.4 and we'll be able to use 3G again..
On GSM Network, I never faced such a problem even on CM ROMs.
The weird thing was that I had no problems using 4.4.x version of CM of the January builds with 3G. They worked great when it came to data. And it doesn't seem to be a common problem, as I haven't read about more than one or two users before me. Switching to 2G/Edge does seem to work. Might be a coincidence, but I'm going to leave it on 2G for a while, just to check.
Either way I would love to use 3G on AOSP. If not, I would have to go back to stock Samsung..
First I thought maybe it happened because of damaged IMEI .. But 2G works! So it's not..
weird problem.. It isn't like the phone says it's not connected to network.

I tried Intelli3G with Xposed, but 3G didn't help either, so I forced it to 2G (within Intelli3G). That seemed to work. After an hour or two (still working), I tried (for the fun of it, since I hate 2G) to press *#*#4636#*#* and under Phone Information, I changed to WCDMA preferred. Data has been working stable since last evening. Might be a coincidence, but I'm crossing my fingers. I've disabled Intelli3G as well. Haven't rebooted after disabling it though. I'm afraid it wold stop working.
Restart seemed to work ok. For some reason it was set to 2G (GSM) only. I changed that to WCDMA preferred again. Seemed to work. I then enabled Wifi to update som apps, and then disabled Wifi. It reconnected to 3G, but now the connection is dead again.
If I go from 3G to Wifi and back to 3G, the connection seems to die. I open Intelli3G, change the mode to WCDMA/GSM auto or any other so data disconnects, and change it back to WCDMA preferred. Data now working. Don't know if I should stop using Wifi at the moment (if it's the transition between Wifi and data that stops it), or go back to stock 4.3, where it seems to be working as it should.
At least I have an (almost) unlimited dataplan, so data on 3G and no wifi is probably best all over, even though wifi at work and home is a lot faster than 3G..
Data has been stable on 2G/3G since yesterday. I've turned off Wifi completely. It's not a solution by a long shot, but at least I know data is working stable (so far) as long as Wifi is off.

Question WiFi and mobile data both broken.

Pixel 6 was having an issue where it was stuck authenticating on my WiFi. All other devices were fine. I reset the phone's WiFi under settings and it seemed to solve the issue for a few minutes but now it can't see any WiFi networks and mobile data isn't working. Calls and sms are working. Tried safe mode, still no connection.
Anything else I should try?

Might as well wait for the next OTA update which should release today. Hopefully that straightens things out without having to take a destructive approach such as factory reset or clean flashing the factory image.
If you only had a problem with wi-fi authentication I'd first be looking past the phone. Sometimes it's the router than needs a factory reset. Or if you only had a 4G/5G problem it could be SIM or carrier related. But since both are on the fritz there could be a problem with the phone's radio partition which is often fixable with clean starts.
