I notice that thís problem just happened today. Sometimes my network signal gets lost, as so for the data.
When I have my network back, instead of showing 4G Lte, it shows H ( OR H, 3G sometimes). I've tried change it to LTE as a preferred choice but it wont let me choose it. It automatically turns back to GMS preferred.
I don't know if there is sonething wrong here. It had worked fine ever since I flashed the Rom. Only today did I encounter such problem.
Anyone knows what goes wrong here?
Thanks so much for helping me out.

ok I tried download new UL2 modem I follwed dirrections first off NO ltw (maybe not in my area) but 4g icon only 2nd my download speed like .15mb
then I reflashed the UL4 modem one comes with now I get decent speeds but seems cut off a lot.. this isn't huge issue as I use wifi at home but when im out and about (which havn't tested yet) im not sure.
now I did follow UL2 let modem direction wondering if changed setting RAT setting shouldn't have... if u reflash modem to rat settings go back? when flashing modems back forth I read you delete Dcache and cache which I did but am I missing something? something else do after or something... thanks
when downloading with just network it cuts out stops in middle of download ... i dunno what deal is anyone else got info on this? if I reflash a modem back do i need fix permsions?
well i flashed orginal modem working alright guess thought icerom have better donwload speeds but wow its slick and clean looking I really like it :O) yaaaa
I had no issues with the ucld2 radio while I briefly tried it. I'm going to be honest a say u don't seem experienced enough to be messing with the RAT settings of the radio, and should leave the default settings alone. On first boot after install dial *#2263# and set to auto, then menu > end, and reboot.
Make sure your apn is set correctly, especially if you are with rogers. Using the ltemobile.apn with the skyrocket even in an area without late results in data drop outs, as the phone searches for late signal. Same goes for AT&T. Make sure you are using 3g apn values, which will work fine for 4g.
I'm having the same problem. I tried Sky ICS 4.2a, then 4.2a-8, then 4.2d, and now 4.2a-9.
I've been using UCLD2 on these and had no problems, until today when I installed 4.2a-9 and all of a sudden I can't stay on LTE more than a couple minutes. It drops down to HSPA and drops the data entirely. I've NEVER had this problem, and I've tried every radio there is. I flashed back to UCLC4 and I'm still having the problem.
I'm searching the forums for a fix right now. I might just wipe again and start over with the base/modem.
EDIT: I've tried changing the RAT on both new radios by pulling the SIM, setting LTE/ALL, then Automatic. No change.
Today I realized that my LTE signal was orange in quick settings on cm11. Also, Google apps weren't working, play, hangouts, and even Instagram! However, if I connect to my WiFi the signal goes white and all apps work against. This problem usually happens on WiFi and a router reboot fixes it, but this time LTE is giving the problems. I am really stumped here. The problem came out of nowhere and I tried reinserting the Sim, flashing a new version of cm, and nandroiding an old working backup. This is pretty urgent sinse most apps are basically useless now when I'm not home. Also, 3g connects fine, just LTE doesn't. Once 3g connects to Google and turns white, switching to LTE keeps it white and apps will work. I'm all out of ideas here, someone please help

I'm in the same boat. Except I wasn't on CM11. See here: http://forum.xda-developers.com/showthread.php?t=2748991

LTE works, just most apps don't load anything, and the signal shows orange in quick settings. You don't seem to have the same problem as me, right?

You're correct, my bad. I can get 3G no problem but cannot even get 4G to show up.
Heyho,
about three weeks ago, my N5 suddenly lost it's signal over night and shows me "Emergency calls only" and it won't register into any network, just giving "Selected network unavailable".
When this occured my N5 had 4.4.2 stock ROM and rooted. I've unrooted it and updated to 4.4.4, but I still got the same problem.
Problem occurs with any simcard, while simcard works with other phones just fine.
Have deleted and reconfigured APN, but didn't make any difference.
I get a signal every few days, but I still can't receive text/calls or call/text anyone and my mobile data doesn't work.
I even tried to downgrade to 4.4, but that didn't solve my problem either...
I'm from Germany, but in New Zealand at the moment, so I really need my phone in case of emergencies and to stay in touch with family/friends.
I have been searching for a solution since it started, but have not been able to find anything that worked.
Sending it back to Google isn't an option right now because I am travelling.
I am really thankfull for any suggestions or if anyone knows how to fix this problem!
Cheers
Have you checked to make sure the network setting says 2g/3g/LTE preferred. Because I had this problem when it was switched to 2g only and was fixed by the above option
If the above fails trying going to your dialer and typing *#*#4636#*#*. Go into phone information and you should see a drop down box to select your network mode. Play around with those until you get a signal but you might not want to try CDMA options (WCDMA is ok) since you're on a GSM network.
Sent from my Nexus 5 using XDA Free mobile app
had exactly the same issue as you mentioned. Nexus 5 tends to lose network without any logical explanation and it tends to work at one place but stop showing network if you walk half a mile down the road (or may not show any network anywhere). Google has released an update in June in which they have updated the modem to solve the problem..given that I am in India and the June update was for India, Australia and Newzeland, it worked like a charm for me (all i had to do was flash the modem from twrp)..people as far away as netherlands have reported the modem to work for them..
NOTE: IF U INTEND TO FLASH THE LATEST MODEM, DO NOT FORGET TO TAKE A BACKUP OF YOUR CURRENT MODEM PRIOR TO FLASHING THE NEW ONE..
check your sim card. if you can, try someone elses.
Alright,
I've tried every thing again so far, but nothing seems to work.
Sitting in the library, I noticed that I get a signal, when connected to WiFi, which stays for 1-2 hours after disconnecting.
But I still can't make any calls or text and mobile data doesn't work though the APN is correctly configured and and data enabled.
I really hope to be able to solve this problem somehow, don't want to put aside my beloved N5 :/

Edit: Haven't found any solution so far and bought a new phone for the moment until I'm able to send it back to Google.
Might be an hardware issue and not software related.

hey kimpfimp... u r not alone .. ive had this problem for 2 months now .. .. i have a nexus 5 and i have this exact same problem .. leads me to believe maybe its software related .. started after lolipop .. havent been able to find a solution yet !
worst part is that it is happening on an Replacement device after i RMAd my first nexus for a power button problem !!
i hope its software related and can be fixed .. because google is now refusing to rma this as im now out of my warranty period !
I was using a custom rom by hroark13 over at AndroidForums:
I don't want to link to the thread since it may not be allowed, the thread title at AF is:
cm11-developer-and-tester-thread-for-zte-msm-8x30-devices.834705
He has since closed the thread on the rom and probably isn't going to do anything else with that rom. I was having a problem even accessing the "Phone Information", turns out you can't use *#*#4636#*#* on this phone, but I did find a code that did work.. *983*3640#
I am currently throttled and I'm stuck on presumably 2G, my problem seemingly starts here, I should be able to connect to 3G since the highspeed LTE data hit the limit and goes to 3G, the problem is, in Phone Information it appears to be stuck on GSM (PRL), some of the ones I select wont even change to it others change to it but when I leave phone information and then go back in, its back on GSM (PRL) again, like it ain't sticking. what could the cause of this be?
bump... Anyway able to help, I know someone can.
Hi guys.
Just trying to share my observation and explore if we can do anything.
I am using D6683 (I think it is support to be a HK based handset). Using Lollipop, it has been working perfectly but 16GB not enough hence MM function that allow SD card and Internal memory merge is appreciated.
Since Sony decide to ditch us using D6683, the only option is using D6633.
1. Try using MM .575, it has huge connection problem. The phone will just stay in GPRS mode even connected to a LTE network. Driving from one point to another point, will just cause it to data connection to hang. Putting it in airplane mode and anything else won't work. Only reboot works
2. Restore stock and upgrade to .291, first day testing seem to be ok. Got LTE connection. It did try to swing a bit but it has been maintaining well. This i started driving with Waze. Connection start to go haywire, but it will be still try to reconnect. Data are "maintained" to certain extend. Let the phone along for about 2 days, the next thing I realize, only GPRS left. The signal logo got no more H, H+ or LTE. Check the phone service menu and all info confirm the LTE is available. Again a reboot fix the problem.
3. Change the setting to only WCDMA + GPRS. The phone was "perfect". No data hang issue and etc
Need all the sifu help. Assuming if the phone is rooted, how is the phone determine the connection method? I presume that the phone will initialize the modem to dial the connection. Can anyone share anything that we can probably trigger a redial and probably eventually inject into the phone data connection sequence. Again using Lollipop, there is no issue.
Appreciate any comments/advice.
Regards
Dan
