LTE switches to 4 bars of HSPA+ yet no internet connection - Nexus 5 Q&A, Help & Troubleshooting

I'll be surfing the web on my phone with LTE, but suddenly the past few days I've had an issue where it'd switch to HSPA+ and I can't connect. I'll have 2-4 bars of H+ yet I can't surf the web. if I turn airplane mode on and off, I'll get LTE again for a minute or so.
I have no issues making phone calls or texts, just surfing the web. My APN settings are correct for my carrier, and I just experienced this only the day before yesterday.
If it helps, I'm running CyanogenMod 11, everything else is stock such as the bootloader, radio, kernel. I'm not sure if it's a nightly rom issue, or what. LTE is strong in this area and i get 3-4 bars at all times. I didn't post this in the CM11 thread since I wasn't sure if it was rom related or not.

If you restart your phone does it work again? I had this issue running early ROMs sometimes.

If I restart the phone, I'll be able to use the phone for maybe half an hour or so, and suddenly it'll switch to HSPA+ and sit there trying to forever load a webpage. Eventually it'll tell me I'm not connected. If I refresh Google Now or any internet connected app, it'll tell me the same. 15 minutes later or so, LTE comes back on it's own, and randomly decides to go back to HSPA+.

I am going out on a limb to say it's a cm deal. Try a different ROM and flash the latest radio.

I'll hold out for a few days. If I didn't have issues a few nightlies ago, I'm sure it's a new bug they'll fix soon. Thanks for your help though! I do have the latest radio also, didn't meant to infer that I had the .17 modem from launch day.

[Q] mobile data not working, poor or no phone signal

Hey guys, I haven't done anything to my phone but all of the sudden, the data and phone signal basically quit working. I have a very hard time getting texts, phone calls etc to go though but it will eventually (usually takes a while or a few tries) and as far as data goes, I basically have no connectivity at all unless I'm on wifi. It says 3g or H every once in a while, but it's really slow and usually doesn't stay for long. I'm running CM9, and like I said before I didn't change anything that I'm aware of that would have caused this problem. It worked fine before, and it just stopped. Ideas? Thanks

have you called your provider? maybe its on their end.
I'm having the same exact problem... it shows my 3g it shows all my bars but instead of the bars being colored or the 3g be in color is gray. Also I cannot get back conectivity until I restart the phone. Does anybody have an idea what this is?
Are you on AT&T? I was not having any problems until a certain point in time, and I didn't change or do anything to incite them. I'm not even getting calls anymore, I'll just get all my texts in a wave every few hours. My data is useless, it won't stream, or load web pages, and my phone is frequently saying "Emergency calls only" when I'm sitting at my freaking house (which normally has full 3g and cell signal and is very fast)
This just started occuring with my 9020a on AT&T the first week of March. I switched SIM cards twice, spent about an hour on the phone with ATT, and sent the device back to Samsung who rolled back the software to 2.3.4 and the Radio to UKE1.
I still have the issue. Samsung says its not them. ATT does nothing. It;s liek the phone just stopped working, started dropped calls, missing calls, and the internet connection sucks. I have an iphone for work through ATT as well and have no issues with signal.
ANy help is appreciated.
Hmm
Make sure you have the right, most up to date settings for APN, and flash original radios. if it still doesn't work, make sure you have the i9020A, which has the at&t 3g antenna, not i9020T which has the T-Mobile antenna, vice versa.
Have you tried other radios for your device (make sure you flash the appropriate ones for your model)? Any signal info under Phone Information when dialing *#*#4636#*#*?

Sounds like you're having the exact same problem I am having. I switched sim cards, flashed different roms, etc and nothing. (although to be fair, after the new sim, things work better, but still not well) I'm about ready to pop my sim back in my craptivate and just go with that... or buy an iphone off of craigslist.

I am 100% sure I have the 9020a, but I don't know anything about APN and flashing radios. I have only ever flashed full roms before, so I wouldn't know where to look for the original radio.

I have not tried other radios. The signal info seems solid, sitting at my house, but the 3g is still horridly slow. It taked 15-30 seconds to load a webpage, even a pretty mundane one like google. Messages still come through in waves, and often won't send
About your APN, AT&T should provide you with the proper values to put in under Settings | Wireless & Network | More | Mobile Networks | Access Points Names.
If you are on ICS, they values should populate by themselves.
Can you try flashing other radios and see if you encounter the same problem:

Make sure you backup your EFS folder (and all data for that matter).
I had similar problems, they were related to turning 3g on/off with a APN widget while the phone had little signal. As soon as started enabling and disabling 3g on the android options everything was back normal.

the data works most of the time now it's just retardedly slow. I can't stream music even on low quality, nor can I watch youtube without leaving it for 5 minutes to buffer,pages take forever to load, and I was downloading a 6 meg app and it took 20 minutes to download whenI was leaving the phone alone and not moving. I got really sick of trying to fix it and finally gave it to geeksquad to send in to get replaced. sigh.

[Q] Radio disconnects!

Here is whats happening! I go into an awful area with no cell service and when i return into an area with good service... It shows all my bars, 3G icon, but its all grayed out and will not return with color... Also i have no data connectivity at all. The only way to resolve this problem is a reboot. I have the Nexus s 4G KL1 radio... This has happened twice in 2 days. Can anybody tell me what this could be? I tried the KL2 radio and the same thing happened. So I went back to KL1. I am running Cyanogenmod 7.1 stable. Any help would be appreciated, I like this phone and dont want to have to go back to my slow Evo.
Happens on ICS ROMs. I switched back to GB because of that issue.
OHHH ok that makes sense since i was on an ics rom... That sux i love the ics roms to. Is this an issue they know about and are working on?
Yes I am sure the devs know about this issue. A lot of people already reported this issue on the ROM's threads. I think there was a fix in the CM9 repositories that was merged this week.
well thats good news since were i live its not good service and im in and out of service a lot. Thanks for chiming in and letting me know! I was wondering if i had a bad radio or some thing lol...
This happens to my I9020T as well (with stock ICS, Pixel ROM, and Brainmaster's Stock and MIUI ICS ROMs). So, it's definitely an ICS issue. My network connection won't reconnect after I ride the subway (underground, where there's no signal) for about an hour. The only way to fix it is by doing a reboot (enabling and disabling Airplane mode doesn't fix it).
I just tried switching radios: from KI1 to KF1. I'll update on the result later tonight.
Sounds like exactly what happened to me.
I went back to gingerbread. I haven't had the issue since!
Just out of curiosity have you tried the KL2 radio with CM9/Latest nightly and then toggle your Data Enabled or the data roaming? If that works it might save you the reboot. Settings, wireless & Networks/more, Mobile networks, Data enabled.
You could try toggling the data roaming too.
Yup tried it already

Ok it was worth a shot. When I travel to the UP, I get no data service what so ever. So I feel your pain.

I've tried enabling-disabling Data as well, and it doesn't fix it.
The weird thing is the same issue happened to my girlfriend's T-Mobile G2 with Gingerbread last week, when I unchecked the "Use only 2G network" setting on her phone and forgot to check it back. So, when she told me the issue when she got home, I re-enabled the "Use only 2G network" setting again, and her phone haven't had the reconnect issue ever since.
So, my speculation right now is this reconnect to network failure issue has something to do with the Nexus S' 3G/4G network type setting.
I definitely think you're right
I am having somewhat the same problem.
My phone keeps switching from UMTS:3 to HSDPA and back to UMTS:3
This is draining the hell out of my battery. But when I have it on EDGE 2G I'm getting good battery life.
the issue is not that big for me. I just give it a few moments with it in sleep and when I go to use it again it fixes its self.

Update!!!! I have since switch off of the I c s rom. I have not had the incident happen even 1 time since doing so. I am totally convinced it's on ice cream sandwich roms.

I doubt the radio would make a difference. I think the issue lies in the Phone application.
I could be misinformed here, but if i recall correctly, our phones radio is relatively stupid as far as radios go, and the intelligent parts are actually done as a part of the phone application. This only applies to CDMA Variants of the Nexus S, but it could be the reason that the ICS update was pulled (As thats where CM and others get the ICS version of the phone app.).
After taking the subway for about an hour last night, my NS actually reconnected when I got back up to ground level. One thing that I didn't do is listen to music (PowerAmp); I was always listening to music when I had those network reconnect issues.
Anyway, I hope this issue gets fixed in the upcoming official Google ICS update, that should be released in a few weeks*.

I've found that if you just stick it in airplane mode when you are about to go into known no service area and then take it out of ap mode when you know you have a signal you can save from having to reboot to reconnect.
My building at work is a tomb for sprints signal and it works for me every day w/o rebooting ...
To all of you having network reconnect issues -- do you use any battery saving apps, like JuideDefender or GreenPower? I use one, and I'm thinking that its network toggling internal API method has something to do with this issue.
Yesterday, I disabled my GreenPower app right before I took the subway, in which my NS couldn't receive any network signal for about an hour. Then, when I went back up to ground level my NS was able to reconnect to my network successfully.
I'll do the same test later after work and update back tonight.

Keep having data issues on my N5

So I had this issue with 4.4.2,.3, and now .4 radios. Sometimes when I switch from WIFI to LTE or from No Signal to 5 bars of LTE, data does not reconnect and I either have to wait or reboot the phone. Its extremely annoying. I am on Stock ROM rooted with Franco Kernel and currently on 4.4.3 with 4.4.4 radio. Anyone know whats going on?
are you undervolting?

Nope, I was and went back to stock voltage but it didn't fix anything
Also, I do get 3-5 bars of LTE in status bar but when I try to accessing internet I get nothing, be it in Chrome or any another app
well, its a known issue on the n5. it doesnt affect me much, as i reconnect to lte very fast and immediately have data. but, every once in a while, itll show me that im connected, but data stops flowing. at that point i turn on airplane mode, let it disconnect, then reenable it. data always starts flowing immediately after that.

i dont know. maybe they are aware and are working on it. but really, for me personally, it really doesnt create an issue. i turn on and off my airplane mode once/twice every week or two.

in feb or march, there was a few week period that it happened 3-4 times a day. thankfully it didnt go on. because of that, i assumed it was a tmobile issue, with them constantly upgrading their network in my area. but now i just dont know(lol).
It could be a tower issue. I have also seen weird things where it tries to connect and when I look at the actual field test app it shows it is on say LTE but reports in Android as searching for signal. A quick test shows the APN may be at fault. I know it sounds weird but for me on Cricket if I delete the APN LTE goes away. I put it back and LTE magically appears.
Also when I had Sprint I noticed there was a weirdness in that you could have an APN for EHRPD EVDO as a bearer or LTE as a bearer but not both it seemed so it would flawlessly connect to LTE but not EHRPD or vice versa.
If you know the APN is right then it may be a tower issue. Some towers may not broadcast LTE near you but ones slightly further away do so the phone may not connect right away.

[Q] Horrible reception-- new phone development

I've started having some horrible issues with my phone connecting to Verizon networks properly. I used to be able to connect to 4G networks at my house and surrounding area with no issue, but now I've been having the worst time getting it to lock. Currently I'm connected to 3G at -99dBm in my household.
I originally was running stock, but fully rooted, S-Off. I've since switched to trying AOKP and now I've settled on Sinless GPe 3.4.7. I have not seen any real difference between them as far as getting a good connection to the network. I started switching ROMs well after I've noticed an issue, and I have not done much of anything to my phone in the last few weeks that I could attribute to the change. I've never dropped the phone or damaged it in any way.
I just recently traveled across the state and would run speedtests next to my wife's iPhone 5c and 19/20 times she'd show full bars with LTE service while I was either on 3G or no service at all. My phone will connect to 4G sometimes though, it's just not that often.
I read that there may be an issue with my SIM card, so I stopped in and had it replaced. The guy seemed very confused about the state of my phone software, so he blamed any issue I was having on the software installed. Regardless I did get a new SIM card installed. It did not seem to help at all. Can anybody help me? I'd hope to not have to go through the hassle of attempting to get the phone replaced!
Bootloader information:
HBoot-3.16.0.0000
Radio-0.89.20.0321
After rebooting my phone, my phone locked to an LTE signal at -112dBm. It does not speed test at over 3Mbps. Testing my wife's iPhone shows her at -100dBm and she was able to pull 30Mbps down.
There is talk of poor signal reception/speed in gpe threads. Cm based Roms, dunno. Try flashing a sense ROM, do some tests and report back
I recommend clean ROM or any other ROM on Verizon base
I just received my M8 yesterday and am having the same issues (both wifi and LTE) running the latest PA. Going to try something with a VZW base and report back.

I reloaded my backup of the Stock ROM and I am still seeing the same issues. It seems to connect sometimes but most of the time it will not. It seems like its just not getting a good lock. I am having trouble even using the phone at my house now whereas I've always had great service here. Doing a speed test now, the phone states 3G service, tested with 705 ping, download of 0.17, upload shot up to 58.19 (which obviously isn't true) and then froze while testing and has been here for over three minutes.

I would run the RUU and try again, and just see if something got boogered
Confirming as well that the reception isn't the greatest with this phone/radio in the so so service areas.
I live out in the country. Never had good reception with Sprint no matter the phone. Switched to Verizon with an LG G2 and service was fantastic at home for the 7 months I owned it. I moved to the M8 and now phone service is spotty at my house. It's the radio for sure. Wifes verizon moto works great at home as well.
I've had the same issue, updated radios, flash back to stock, and everything else. The radio on this phone IMO is terrible, even when it does get 4G I get like 8 mbps down with 4 bars of 4g. Once in a great while i'll get 18 - 20 down with 5 bars of 4g.
I've been experiencing the same things recently as well. It also affects sending SMS messages. I am on stock too (with s-off). Nothing changed on my phone though, it just started dying.
Never had signal issues. I live out in the boonies too. Signal is strong and switching between 3g and 4g has been smooth. I've been able to download torrents as fast as 5mb/s. Speed test results have been just awesome. As far as signal goes, it's been better than my note 3, DNA, and my wife's droid mini. And this is my second m8. My son has the first and it is the same as mine.
I would look into exchanging them if they don't keep up with other phones. The radio in this phone is actually pretty damn sweet, so if u got a funky one, I'd exchange it. Def try the ruu first, then exchange if that doesn't help.

[Q] anybody else having 4g connection issues?

About 3 weeks ago after installing the update of liquidsmooth 4.4.4 i randomly started dropping to 3g service in places that i normally had full 4g available. It has slowly gotten worse to where if im not on wifi, than the phone is pretty much useless. i normally have full coverage everywhere. so i originally thought that maybe something had gotten messed up on the update, so i did a clean install of liquidsmooth 4.4, and blackbird kernal and same thing still occurred. also tried carbon rom and slimrom, and no luck. so for the fun of it, i went ahead and reflashed the phone back to stock from backups and rerooted it, updated the modems and reinstalled liquidsmooth w/ blackbird kernal, and same thing. i have went through all the mobile networks settings and tried everything and nothing seems to help, idk if that update screwed something up or if its an issue that others have been experiencing as well, or if im just screwed and my phone phone is dying.... any help is appreciated thanks

I'm currently running OmniToad, and ran CM 11M8 for a short while. On T-Mobile at least, with the custom ROMs it's normal to see H+ only when data is being transferred; it will drop back to 3G otherwise. When I ran the stock ROM on the Relay, it would always say "4G" regardless of whether it was in UMTS (3G) or HSPA+ mode. Apps like SignalCheck or CellMapper will tell you which mode it is really in.
On the other hand, if data transmission is only going through as 3G, it could be a phone issue or a tower issue. Is LTE available in your area, or are they just getting it set up? I know when T-Mobile was upgrading the Chicago area to provide LTE, there were a few glitches here and there.
It was stupid for T-Mobile to brand HSPA+ as "4G" but that's a different rant.

yea LTE has been in this area for quite a while now, i had it with my S4 and it worked perfectly, i never had a problem with the service on the relay either up untill a few weeks ago the internet speed and and data coverage was great, not quite as fast as the LTE on my S4 but it was still more than adequate, i used to use the hotspot and stream netflix on my laptop. now i can usually get a text to send but calls usually fail and if i try and use the internet its impossible. it almost seems like its doing the exact opposite of what it should be doing, as soon as i try and use anything (not while connected to wifi) than it drops coverage to 3g/edge/ or to nothing at all. Im leaning towards the hardware failing side, but i figured i might as well give it a shot and post it and see if maybe i wasnt alone. thank you for your reply.
small note of background on me: first time posting ever in this forum but have been using the tools and roms from it for a long time, so im not a complete noob, but i definitely still have a lot to learn.
