My Nexus 5 frequently loses mobile data connectivity. Its been happening since I purchased it, but the frequency with which it happens has increased since I flashed the M1 snapshot of CM. I've since flashed the second snapshot from early January, but it has not made any difference.
This is the same sim card that ive used with my nexus 4 and my htc one without any problems, and I've made no changes in my wireless carrier.
Does anyone have any thoughts as to why this happens?
Try a different,maybe older, radio. If that doesn't help go back to stock and see if it persists.

Flash the Nexus factory image. If that fixes it, its a problem on CM's side

hi.
i was this problem too, not exaactly the same, but somehow similar. I have 3g connection, the signal bar shows H and somtimes 3G, but the speed is freaking slow, worse than 2g. Initially I thought its something wrong with my phone, been changing ROMS to see if it is the issue, but no. Then I flash the latest baseband / radio, and still doesnt help.
Be reminded I am on 4G plan, but never had any 4g network ( it is not because i'm not in an area with no 4g network )
I was very frustrated and emo at the same time, thinking of RMA the phone, thought it is the radio chip problem.
but then... I called my telco, asking why I'm experiencing slow connection and bla bla, and I don't have 4g network. They keep saying my network is working perfectly, and running normally, I requested them to reset my network connection. They agreed and asked me to turn off the phone for a few minutes then they reset the network for me.
After that, everything is running perfectly.
This was 2 days ago. And guess what, I don't have any 4g connections now again. Stupid telco, I'm going to call them later when i'm free. grrr.
but please make a call to your telco and ask them.
Hope that helps

Im in the DC area and my phone wont connect to 4g for life of me (im in a strong 4g area). tried toggling. tried forcing LTE only(either 1x shows up or nothing at all). tried turning off data for 10 minutes. tried removing battery. tried full wipe (wiped three times cache, tried clearing davlik cache and battery stats...three times) reinstalling 1.7. I can still connect to 3g and 1x. Just no 4g
i was initially on bamf's 2.0b5 and noticed i couldnt get 4g. so i restored back to 1.7 and still no 4g. and no i didnt forget to flash the appropriate radios. i called verizon to see if there were issues with the network in the area and they came up with nothing. is my radio broken or am i missing something here?
Try starting the phone up once without the sim card in and then reinstall the sim card and see if it works.

just tried that. no dice. any other suggestions?
Maybe take it in to vzw and have them test the sim. It could be fried.

whoa. i didnt know that could happen.
same thing with mine I am in Manasasso area and i get 4g off and on but cant get on the market or google, then i back to 1x so is it a phone issue or a system issue.
Well with me its not even on and off. I get nothing at all.

I'm sure this is a stupid question but it must be asked. Do you have the back of the phone off?
no such thing as a dumb question. just dumb people. hahaha im kidding. just trying to make light of the situation a little at least. i had a teacher that would always joke around like that so i had to say it.
but i digress, no the battery cover is not off. like i said, 3g and 1x works. just no 4g. can it be possible that just the 4g radio could be broken or if that were the case, i wouldnt have any data network at all?......
and as i was typing this message, my 4g connection had just connected. i think it has to do with the area where i live because I am now in my work building and it seems to be working fine now...i guess verizon lied to me... thanks for the suggestions. will post if things change.
Well, according to Verizon and their coverage map I'm supposed to get 4G at my house but I don't. Granted, I am on the edge. Now, here at work is a different story...solid 4G and it never looks for 3G.
Yeah, I am supposed to have 4g at where I live too. And I would get a strong signal too, which was why I was totally stumped when i couldnt get a 4g connection all of a sudden and verizon told me there were no problems with the network in the area.
this is happening to me as well. Phone keeps jumping between 1X and 3G all the time. I rarely get 4G anymore
I'm on Perfect Storm1.5 running the MR2.5 Radio chingy leaked
I have tried 4 different radios as well as ROMs over this past week, no change on either
been 4 hours and phone hasnt dropped 4g since. even flashed back to bamf 2.0b6. I would get no signal on reboot, but toggling works like usual again. i guess where I live is having problems right now. will post when i get back.
working now. im guessing its the network. running 2.0b6 with mr2.5
This was happening to me as well. I would sometime get "4G", but it's fake 4G, as I would not be able to receive any downstream data, and connectivity would soon cut out. I've gone from GingerRemix 2.1 back -> 1.7 -> 1.63 -> stock -> stock unrooted, and could not get 4G back.
I decided to throw in the towel and go to Verizon (with GingerRemix 2.1 loaded), to compare. They definitely had 4G in store while I was carrying 3G around. I told the "device specialist", and without much questions, he popped in a new sim card for me. I had 4G then until I was about 4 steps out the door, and it would fall back to 3G. The dude and I spent the next hour swapping out another card, placing my sim card into a returned TBolt, but no luck. Finally, he did a factory reset on my phone. With no further luck, he resorted to ordering me a new one.
Still unsure what the issue is since he did give me a new SIM, and that SIM didn't work on another TBolt as well. We'll see whether the new one that comes in the mail tomorrow will fix the issue. I've since then reverted back to stock, since I need to mail my "broken" phone back to VZ, still no 4G.
I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw
I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?
I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

In the original post, I stated that was one of the things I've done.
have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7
fwiw

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?
When I'm on data, my phone is stuck on EDGE or GPRS when it should go up to 3G or H+. I've tried restarting my phone, turning wifi on and off, turning data on and off and made sure my settings looked okay. Any help is appreciated!
Cataclysm 11/26, Franco r14, dalvik patch. And if it's relevant, I'm on Rogers wireless.
I'm not sure but doesn't Rogers use global frequency in which case you need the 821 model?
I've definitely had 3G and H+ on my N5 (abbreviations much?), but it just seems very inconsistent. It'll go from H+ to 3G, back to H+, then cut out completely, then sit on E or G for a while. Just trying to pinpoint the issue because it's getting annoying haha. Perhaps it's the frequency that's screwing it up but that's definitely not my area of expertise. I do have the D820 model if that's helpful.
I'm having exactly the same problem with Fido right now, I tried pretty much everything including
- flashing back the factory image
- tried every modems from the xda thread in the Nexus 5 Android Development section (currently my phone is on the D821 modem but it didn't change anything)
- changing my apn (but it was obvious that this was not the problem since the phone had a edge connection.
I'm really about to call Fido...
Still, I'm kinda glad to see that i'm not alone.
maybe that the data service in your personal area?
Well going back and forth between 3G and H is normal. It picks up H/H+ when receiving/transmitting and goes to 3G when idle to save power.

I called Fido, the technical support told me that they had something that was blocking me from 3G (but he didn't tell me what it was, he just told me that something was blocking me...) I had my beloved H+ back for maybe a whole minute and then it just switched back to Edge network.
All I wanted to know was if many customers have reported the problem or if I were alone...
Maybe if I'm lucky my phone will get back its 3G soon just like you.
I'm still having the issue today.
I called back Fido and they tried different things like desactiving/activing back my line, "updating my line" and more without any success.
Then I called google and told them the problem. They will change my Nexus 5 for a brand new but at the same time I feel like it is a software issue and not an hardward one... Well, we'll see, I never had a problem like that with any other phone before and the Nexus 5 never had any problem with 3G before yesterday.
I haven't tried everything yet, maybe you could try :
If you are in a LTE area, can the Nexus 5 connect itself to this network? Nearest LTE area from where I live is like 40 minutes away, bit too far just for a test.
Try with a sim card from another company like Telus or Bell, is the phone connecting to the 3G network? (I though about this while calling Google..)
Well, hope that the next phone will be ok.
Here are the few pictures just to show you a proof that even when I request a webpage, the phone will stays on 2g only.

Thanks for the update mark1s. Definitely let me know if a new phone fixes anything, although I'm also thinking it's a software problem.
The problem could just be that there happens to be patches of low coverage in the areas we're testing this out, which seems unlikely in big cities. But testing at work seems to have this problem, but testing this at home I pick up 3G and H+ just fine. Odd..
I've been happily using an HTC MT4G Slide/Doubleshot I got on Ebay since December (I'm in Canada, using it with Wind Mobile, AWG 3G bands). Last Sunday my phone suddenly started showing "No Signal" for the cellular connection (wifi still works just fine), even though I had full signal bars, and I was unable to complete calls, even the *611 carrier service calls. With the Wifi turned off, I noticed I was still receiving emails, oddly enough, even though I could not register on my network. My SIM was working fine in other phones, and a SIM from another carrier (GSM 2G only) worked just fine. I tried a new SIM from my carrier, no luck, same thing.
I know AWS splits its up/downlinks between the 2 sets of bands it uses (1700MHz for up, 2100MHz for down), so I'm guessing something strange happened to selectively knock out the up bands only. But what? My phone is on EmmanuelU's KitKatDS 1.3, but the only unusual thing I could think of software wise was that I had recently updated Xposed framework to the latest version. I though maybe that did something weird to the baseband firmware, so I restored the original stock Gingerbread ROM via ClockworkMod - no change. I applied the available OTA updates from T-Mo - nothing. Re-flashed KitKatDS & restored by current set-up - nothing.
I'm completely stumped and seriously starting to worry it's some freak hardware thing. Anyone here ever experience something like this?
Thanks for any of your thoughts!
Never seen this myself before, check your apns would be my next step. Maybe try *#*#4636#*#* from the dialer and see if what it says there too. But mostly I'm stumped

Hello everybody,
I am using a Nexus 5 for a full year now and I noticed from the beginning that I never can get 3G signal, but when I am in the nearest city I van get 4G/LTE. Last week I wanted tot know more about it so I inserted my sim into another phone and immediately I had full 3G connection. So I updated to 5.1.0 with the new radio for 5.1.0 and I still couldn't get 3G. When I googled for 3g coverance I noticed I shoud've get full 3G. however only 2G and 4G works but the problem is that there is no 4G coverance in my hometown so I am stuck at the slow 2G. I'm in the netherlands and I already tried all options in *#*#4636*#*# but I still dont get 3G. also my apn settings are correct. so my last hope is to ask here if anyone knows what to do. I'll include a picture of my baseband version etc.

If it doesn't work after clean flashing factory images and trying different radio versions, it might be a hardware problem.
It's sad because I don't have any warranty anymore because I've opened the device up to replace the screen myself. Do I need to change the whole motherboard?
