Data Goes Away / Very Low Sometimes - Nexus 5 Q&A, Help & Troubleshooting

On certain ROMs, such as Cataclysm, my data signal goes away after disconnecting from the WiFi. But this has been happening on several other ROMs, too, and I can't seem to find the reason behind it. In case it matters, I'm using my phone on Sprint, data works fine with the stock ROM, and problem starting occurring more often after the 4.4.1 update. Any suggestions?

What you described looks similar to my problem.
I’ve been flashing 4.4 and then 4.4.1 ROMs on my Nexus 5 since I’ve got it early November, but I have not updated bootloader and radio up until yesterday. This week being on Slim 4.4.2 beta 1.5 I couldn’t connect to mobile data even though I had 4 bars and it was showing 3G or H (no LTE here yet, at least for me). GPS was fixing my location on Google maps, but navigation was not able to recalculate the route and was not moving my position along the way. Only when I switched from navigation to map, it was showing me as moving accordingly. Maps also couldn’t search for the address I was looking for. Now I realize it was a data connection problem.
So I thought it’s because I’m using 4.4.2 ROM on 4.4 bootloader and radio. Yesterday I downloaded Google 4.4.2 factory image and fastboot flashed all (efrant, your guide is irreplaceable!), formatted cache, did a factory reset and all. I wanted to have 100% factory state device. What a surprise today morning, when I realized I have no mobile data. Orange 4 bars signal with 3G or H. No internet though. Rebooted – the same: max signal, no internet. I turned Airplane mode on and off. Signal is back and I have internet, but bars still stay orange. So I rebooted. No internet on full 4 orange bars. Airplane mode switch on and off – mobile data regained, yet still orange.
When I reached the office I turned on WiFi. Got strong WiFi connection, bars went white, both WiFi bars and mobile bars (in Quick Settings). I switched off WiFi – mobile data is not reconnecting, staying orange, showing 3G or H. Sometimes it’s coming back after few seconds, sometimes it requires switching Airplane mode on and off to bring it back.
WTHell?
I was never putting much attention to mobile data because at home and in office I’m on WiFi, and while driving I’m listening to audiobooks so I don’t see what’s going on with mobile data. Sometimes I take a train, and then I’m browsing xda – I don’t recall having connection issues in train up until recently. But what I recall now, for some time, when coming back home and turning on WiFi, email notifications were popping up immediately. Does it mean I had no mobile data and phone synced only after it had WiFi?
This is annoying and driving me mad. Do I have to fastboot flash 4.4 factory image to see if it’s gone on 4.4?
Any ideas what can I check before going through factory img flash again?

Does your data eventually kick in after a few minutes, or are you without data for an extended time after disconnecting wifi? I know with Cataclysm if you enable Smart Radio it takes some time for data to ramp up after disconnecting wifi, although I'm not sure about how other ROMs handle this.

I'm on full stock 4.4.2 now, just roorted with SuperSU 1.80, no mods at all. I wanted to check if it is related to custom ROMs or general.
It's random, after switching WiFi off, mobile data sometimes comes back after minute (rarely) but more often I need to switch Airplane mode on and off to bring internet back, but even this does not work all the time.
Mobile toogle shows 4 bars with 3G or H in orange colour (screen attached) when there's no data or there is data. Never goes white for mobile data (I remember it used to). Now it becomes white only after I switch on WiFi (2nd screen attached).

Hopefully it's not this but I've been seeing more and more people starting to experience it. Mine started acting up slowly and then now it's having the issue in the thread linked below.

I've seen this thread, but my problem is different. I'm not getting the "emergency calls only" message. I can call or receive calls without problems. It's mobile data which can't reconect after switching off WiFi, even though mobile signal is strong - 4 bars and it's showing its on 3G or H. And Why it stays orange even after it finaly regains mobile data?

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.

AOKP JB 4.1.2 Mobile data dropping and not reconnecting

I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

3G "disconnected"?

Hello, I recently flashed CM 10.1 on my Note 2 and the mobile data seems a bit weird. For instance, when I enable the mobile data, it connects quickly and perfectly. However, after about 10 to 15 minutes, I don't know why even though it said to be connected (you can see the 3G/H+ icon and the signal bar was in blue), when I try to refresh a webpage or use services that require data connection, it fails to retrieve data. However, after I turned off and turned back on the mobile data, it works perfectly fine. This doesn't bother me allot as I do not leave my 3G idle for long time, but I still wants to know why and to see if there is a way to fix it. Thanks.

Modem Freezing? Dropping internet.

UPDATE: Here's a screen recording showing the issue.
NOTICE! You might see battery-saving apps running in the video, but I have factory-reset and un-rooted twice and run FULL STOCK no apps like that installed, and I still get this problem<<<
Youtube: http://youtu.be/MGPxlV2Q-0I
I've got a N5 from the play store right when it came out. I've noticed that randomly during the day if I'm using the internet via browser, apps, hangouts, etc the page / app will suddenly lose connectivity. Not just the app though, nothing on my phone can access internet. The status bar with show full bars, and 3G or H connectivity and activity, and when I pull down the quick settings the connection is white, not red. So I toggle airplane mode, but when I do so there is a long delay where nothing happens. Maybe 20 or 30 seconds before airplane mode finally kicks in. Then after disabling airplane mode, I can use the internet again for a while before I have to repeat. Sometimes I cannot get internet back whatever I do though, including reboots, airplane mode toggles, other toggles, searching for networks, network mode... etc.
Often toggling airplane mode will also allow apps to refresh for a second or two (I get a handful of instagram, whatsapp, Hangouts messages, etc) then all connectivity halts again, even though it's showing it's still connected.
Any thoughts what might cause this? I've flashed older radios, wiped and flashed several Roms including full stock not rooted, and I keep having this issue.
There's a chance it could be my carrier, but my wife's phone on the same carrier (but a store-bought N5) never has this issue...
Thanks for your input! Getting REALLY frustrated at this...
rooted? are you undervolting?

What carrier? And have you been tethering? I'm seeing similar problems on T-Mobile USA with full-blast LTE while tethering.

I have this problem when rooted and when full stock, no UC or OC, UV or OV.
I've tried Roms, kernels, radios, wipes, shakes, yelling, crying...

I'm in Canada and on Wind Mobile. No tethering though. :/
Updated OP with video & link. The issue is getting worse and I'm trying not to throw my N5 through a wall...
It seems like I have the same issue. When pulling down quick settings, does it show for you too only the upload arrow?

I have noticed that often - but not always - this is the case.
Do you have this issue often?
Does airplane mode take forever to turn off the cellular radio when this happens?
Thanks!
I have the issue maybe once a day. I have never tried airplane mode, but turning off cellular data from that stage takes a looooong time (atleast 20 sec).

I've been having the same problem for some time now. Exact same description as OP. I'm on T-mobile using Cataclysm Rom, but I've gone through Cyanogenmod, AOKP, Stock and PA and still get the same thing. Was looking for Radios to see if that fixes the issue.
In addition to OP, I've noticed too that often I can't connect to any network, or mobile internet will never go from connected (red) to fully connected (white).
Also sometimes the signal shows red (not fully connected) but my internet is working fine....
And other times it can't find my network, and scanning shows no networks, then later, same location, 10 different networks show. Open sky, not inside.
I'm hoping thisnisnpart of the 4.4.2 bug dealing with dropping internet connection, but not sure...
I've tried radios, might try again. My next attempt will be a new Sim card / talk to carrier again about a misconfig. Then if no luck, I'll see about a replacement phone...

[Q] Constantly loosing connection

Almost since I got my nexus 5 last year it has been loosing its connection about two times per day. It does this in three different ways.
1. total loss. The little outline of a triangle appears and a notification that I have lost my connection. Clicking the notification opens the manual selection of networks. I select the network and all is fine.
2. full connection with an exclamation mark. solves it self by waiting for a while.
3. full connection with H/3G but when trying to access the internet there is no connection. This one is really weird. The solution here is top open the quick settings, select flight mode, which greys out the connectivity triangle but keeps the H or 3G part white on top of the greyed out triangle that has a slash over it. About a minute later the H or 3G disappears and I can turn off aeroplane mode. This either restores the connection or jumps to problem one.
First I thought its a hardware problem, but since I don't want to part with my phone I never sent it back to google for fixing.
When android 5.1 was released I installed that manually and surprisingly did not have any problems at all after this. But then I went abroad and using the same sim connected to a local network in the country I went to. It took 4 tries to join one of those networks. When I then came home this problem started again.
My thought is that there is some setting that should be there that stayed from my trip. I have tried clearing all caches from the storage in settings and the dalvik cache. No difference. I'm not to keen on re-installing my phone again. So my question is, has this happened to anyone else? Did you solve it? Is there something I can do to remove all previous settings for the network to make it work again? Other suggestions?
This happens to me, at least 4 times a day for me, it has only been doing it since I installed 5.1 on my nexus 5, which was a brand new one from Google since I smashed my screen and they just gave me a new one, I'm in the UK btw, not sure where you are but it does take forever to connect to mobile network when I turn wifi off too.
I constantly lose connection at my house going from E to H+ to LTE throughout the day

I'm in Spain.
For me it happened before 5.1 as well. But 5.1 fixed it temporarily, until I travelled with my phone. Have you had to switch to another network with that phone?
For some reason when manually looking for a network it seems to be running on a timeout function because it takes me 60 seconds to get the list, always. This feels like a very antique solution, they should just populate the list as a network is found like wifi does it.
