Question Mobile data works sporadically - OnePlus Nord CE 2

I've played with APNs, I've reset, I've enabled airplane and reset, I've toggle various settings in efforts to make things work
However, the mobile data symbol has the ! symbol in it *most* of the time. I have gone days with it working normally, but it seems to freak out when I travel a bit and bounce between towers. I've had OnePlus phone before ( last was a OnePlus 7 pro ) and they have worked fine. I haven't changed carriers. Is anyone else experiencing this?

Yes, me too. The last update seemed to have fixed it but it is still very inconsistent, wifi too

Network Problem with my phone

Hello all,
Lately (meaning, the last couple of days -- perhaps 3 or 4), my phone has been unable to get a Verizon data network connection for a certain amount of time (4G or 3G). WiFi works fine. However, anything else doesn't work, say, for a few minutes, or a hour or so. Sometimes, a reboot will fix the problem, but sometimes it won't.
The odd thing is, the "4G-LTE" icon is displayed and shows activity (up and down arrows blinking), yet I can't browse the web, update the weather, update Facebook, check email, etc., etc.
Does anyone have any ideas? Running BAMF 1.3.2. I am in the middle of NYC (plenty of 4G service). Yes, Mobile Network is enabled in the Settings. Tried a battery pull as described above AND a SIM card pull. Still no fix.
I had a similar problem a few days after I got my Thunderbolt. I was still on stock yet. I ended up going to the Verizon store and they did a hard reset to fix it. It sucked because I lost all my data but since it was new I didn't have much on it. If you back up everything with Titanium Backup it shouldn't be too bad tho, factory reset is under "SD card and storage" in the settings menu.

There have been many problems with the TB and data/network problems as of late. I believe it to be because of this new 4G rollout that is coming Thursday, plus the fact we will be seeing an OTA quite soon they are propbably preparing the network for that, thus giving all of us all these weird problems that we have been having.
(everything above is just rumor and based on my 100% factual opinions )

You are describing the same problem I'm having and I also live in NYC. But, I have no problems getting data when I force the phone into 3G mode only.
I notice the data connection problem even though the 4G symbol is up when I don't have cell reception for a while...like being underground while on the subway.
Turning the phone off and on or rebooting seems to fix the issue. I'm thinking the phone has handoff issues with whatever tower is near by.
Anywho, I did the "data fix" by changing the EVDO setting from eHRPD to Rev. A. I dunno if that'll do anything.

Nexus 5 Wifi Issue

So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

There was a thread around here somewhere that suggested turning off your mobile data helped fix this problem, I think it was in the N5 General forums.....here it is:
http://forum.xda-developers.com/showthread.php?t=2550690
Don't know if it'll help or not, just saw your thread and had just looked at the other one, figured I'd toss it out there.
Thanks for the reply, just tried that solution but still no luck.
I have a similar problem except that there are phases of wifi not working.
Sometimes I would have around 20-30 seconds of WiFi not working and there would be no data transfer.
Speeds are still fast when it is working however.
I played a little with only using mobile data and no wifi, and everything worked. (Small sample size however).
Seems like this is a WiFi only issue.
So somehow overnight the wifi has managed to fix itself, will report back if the problem returns.
The issue with the wifi returned unfortunately.

Don't know if you've tried this but change your WiFi frequency band in advanced setting to either "5 GHz only" or "2.4 GHz only," whatever your router uses. Might be worth a try.
Thanks for the help, but I've tried changing some settings in advanced wifi settings but it hasn't worked. Even what you recommended I've tried that before and it didn't work.
wifi issue
Also I have the same issue - Im connected to router by wi-fi, home and work and time by time (5x a day) wifi stops working. Wifi is enabled in settings, but there is no connection. Restart the cellphone helps, but after that, maybe an hour, it appears again.
Issue was in 4.4 and still appers in 4.4.1.
Yet did not found how to solve it.
I have the same issue on my gnex running shiny 4.4, but I also had the same issue on 4.3. Tried the wifi options, nothing worked. Unfortunately, no solution for this device that has to last one more week. The double swipe down and tapping wifi gets the connection back, but it is only a work around.
The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

Hey,
I have the same problem with 4.4.2.(factory rom, no root or not unlocked). Sometimes the wifi not works and get orange. I must put airplane mode to fix it. Its annoying.
But as well happens to me:
When I go out from office or home (where I have wifi connections saved in phone) the phone automatically switch to data plan from carrier. But when I come back the phone stays with data and there is not automatic switch to wifi. Sometimes it help to put wifi off or always airplane mode on/off for a while.
I do not know if it is normal behave of android but I would like have automatic switch to wifi.
I tried to change wifi details (changing bands, etc.) but not helped.
Please help. Thank you.
Is custom ROM or kernel will fix it??
For some unknown reason, as soon as I updated my router's firmware, the problem disappeared.
Updated Android 6.0 solved the issue

So I had the unfortunate experience of having my wifi go down while on vacation and for 3 weeks I spent a good chunk of time wiping and reinstalling multiple versions from Cyanogen, Paranoid android and 4.4 - 5.1 to no avail. I just did another factory wipe today and installed the new Android 6.0
The Finger Pointing Game is OVER
Read through 30+ pages of other android users with similar experience and some people send their units back to LG and some even managed getting a new handset. There was never any hardware issues with my unit I just couldn't turn on the WiFi but after the install WiFi works? Guess next time you push a software update to our Phones CHECK YOUR SH*T google and Maybe DON'T Take 3 months to FIX your F*CK Up.
I have a similar issue. Since Lollipop my phone almost never automatically connects to my WiFi anymore. What's wrong?

Data not reconnecting (CM12.1) after disconnecting from WiFi

Please be patient with me, I'm not massively tech-savvy.
I have a OnePlus One with CM 12.1-YOG4PAS3JL.
I have the same issue as described on the Cyanogen forum - but with CM 12.1. I've posted there but nobody has responded! Issue is as follows:
After being connected to WiFi for hours, my phone will not reconnect to data after losing WiFi signal. Phone signal is fine. The fix is to turn aeroplane mode ON/OFF or to restart my phone. If I connect to WiFi for 2 minutes and dis-connect, this problem does not occur. After restarting the phone or turning aeroplane mode ON/OFF, this problem will re-occur after being connected to WiFi for an extended period of time.
My phone is apparently on the latest OnePlus One version of CM, yet my problem seems eerily similar to the above thread I described - so this seems like a known problem. I've contacted OPO Support but let's just say their responses are slow.
Thanks for any advice. APN settings are fine & already done a full factory reset - did not help. SIM not changed, data plan not changed.
The phone has just gone over 6 months old (6 months and a few days), so I'm not sure whether OnePlus One are going to try and get out of any warranty clause. I have never installed any OS apart from what the phone told me to download in 'check for system updates'.
Thiis issue is fixed on CM13 Nightlly.

Use profiles. I use this in RR 12.1.
Default profile -->when connect your WiFi -->preferred network --> 2g
Create a new profile, example:
Street profile --> when disconnect your WiFi --> preferred network --> 2g/3g/4g
It did trick for me.

Data Connection Drops on Moto G XT1045 (T-Mobile US)

I was curious if anyone else experienced or has familiarity with this issue. I've been dealing with this since I got the phone almost a year ago. Sometimes when my phone has been idling and I return to check something, the data connection will be unusable. The 3G icon will be visible but internet unavailable (4G works fine, but I prefer to have my phone set to 3G only). It's possible to wait 30-60 seconds for the connection to reset itself, or under settings, switching "Cellular data" or Airplane mode also restores it. Aside from that, the connection is mostly reliable & I don't have any usability issues once data has restored.
I've always ran CM & LOS on this phone so I haven't tried using a stock ROM (solution suggested in an older thread... Mobile data cutting out). I've also flashed the latest Lollipop Radio Firmware (fsg & modem). Thanks for any help.
Edit: I think this may have had something to do with visual voicemail being enabled. I've since switched to AT&T where VVM hasn't worked at all (they suggest using their app) and the problem has gone away.

Ulefone Armor 8 Pro - strange data bahaviour

Hi, recently I bought Ulefone Armor 8 Pro for my wife, and there is a strange problem with it. When she enables the GSM data, ther switch lights up, but there is not internet connection (also the arrows near the signal icon do not appear). She then has to go to connection settings, and change the preferred network from 4G to 3G. It then starts to work fine, but when she disables the data for the night, and enables it the next morning, there is no internet again. She then has to go to the settings again, and change the preference back to 4G, and it starts working until she turns the data off.
Turning the data off and on again after a short time does not cause any issues.
If the data starts working, the network preference can be changed around and everything keeps working. The issue appears only after disabling the data for a long time (I don't know how much).
I filed a problem report with Ulefone a week ago, but they didn't answer. Does anyone have an idea how to solve this?
I have also this model, and no problems.
Check if there are any ROM updates available.
