Hi, I have a very particular issue with my Oneplus One which it seems to me software related and I hope someone can help me here. I've tried to find an answer here in the XDA and in the Oneplus One forum but no one seems to have the same issua as mine. I've also tried to flash different modems, and doesn't fix it. Tried to play with the *#*#4636#*#* menu and didn't have luck as well.
Before I start I'm on Three network in UK. My phone is rooted but no Xposed installed. CM11S latest version installed.
Things I tried to solve the issue:
I've already tried to flash different modems or play with the *#*#4636#*#* menu but I have no luck. Tried factory reset, complete wipe on recovery and restore of the CM11S. Nothing helped.
What it happens is that sometimes, using HSPA or LTE I'm not able to use the internet. It doesn't seem to be a signal issue because I have full bars and I can even see the arrows up and down in the status bar inside the signal meter. I'm not able to use browser, listen to Spotify or anything internet related. Calls are ok. It usually an issue when I'm on HSPA+ but sometimes in LTE as well.
A reboot usually does the trick and makes it work, but sometimes not and it takes a while to come back and connect. That's really annoying.
Just another piece of info, it usually happens when I disconnect from Wifi and connect to the phone network or when I don't have signal (I'm in the tube for example) and come to an area where I have signal.
I hope someone here might be able to help. The only thing I haven't tried yet is to change to other carrier. But that would be last option as I appreciate the All-you-can-eat data allowance from Three.
Thank you in advance.

Have you checked if you had the right APN ?
Yes, Apr settings are right. Just to be clear. I can connect to HSPA and LTE. What happens is that the connection drops and just fix if I reboot.

Same problem here. Have you found a solution? Or is it a hardware problem?
Hey sorry for bumping an old post but I'm having the same problem. In the UK on non-EE T-mobile. I get enough signal and H seems to connect, but I can't access the Internet. The upload arrow shows but the download arrow rarely appears.
I've tried flashing different roms, modems, recoveries to flash them, all to no avail
I have the same problem, but I don't have to restart, putting the phone in airplane mode and releasing after 2 seconds does the trick. still very annoying. no one has any idea of how to solve it?
My ROM is CM11 44S

Ok here is the problem... I rooted the phone, played with some settings, explored the android platform in general. Somehow, my data has stopped working. I can make calls and send texts no problem, when I try to access internet or google play store, it fells me that I have no data connection available or something of the sort. I have tried flashing different roms, played around with switching between Global and Lte/cdma radio bands. When I switch bands, I get either 4g or 3g, but within half hour it stops working again. After a restart, same thing happens, it worka and then atops. I figure there is something messed up with the modem. Please advise.
Also, anyone else experiencing sudden restarts with CleanRom 5.0? My phone reboots every once in a while for no apparent reason.

Have you tried flashing a different modem?
Worst come to worse, ODIN back to 100% stock and start over.

No clue how to flash a modem
http://rootzwiki.com/topic/34053-of...zon-sgs3-sch-i535-odin-or-recovery-flashable/
Pick the latest from the right column and flash in recovery as you would a ROM.

Looked into it a bit more.... my 4g or 3g works after a restart as long as there is a demand for it, ex. While surfing or streaming radio, as soon as there is no demand, the phone shuts it off and I can't turn it back on. It tells me no signal found for mobile networks. While voice and mssg still work. I refreshed the modem and that didn't help. Short of going back to stock, any other suggestions?
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

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 !
This is what I told support, but they wouldn't help me:
I have the GSM and 3G frequencies, but still it disconnects for a 15 seconds to 3 minutes a few times a day.. It disconnects from all phone services, even though I have great reception/signal. Why? How can I fix it? I saw this 'preffered type' of network or something in these advanced testing settings where you could change between alot of different network types like WCDMA, TD-SCDMA, LTE and so on, is there something I have to change there? If it helps I live in Norway.
""
So this has been going on for a long time, now I got a suggestion that it might help to flash new radio software (.zip?). I know about adb, fastboot and flashing using recovery, but I don't know what radio to flash, if tharæt's the problem. The phone can also use 15-30seconds to turn on WiFi, from what I know this might also be related to the radio software.
If you want pictures or more details, just ask
Thanks in advance!
Hello
Whitch software?
Just for test: switch off the wifi and test that your problem goes away or still present.

It happens several times a day, with or without a connection to WiFi (but I don't know when it will happen, so WiFi isn't off normally).
If possible try to switch off the wifi and test it.
Somehow my s8+ loosing reception all the suddenly.
phone has never been dropped.
i am loosing cellular signal all the time. no mattere where i am.
first i thought it was software problem, an did all the right things. safe mode, checking third party apps,
hard reset, an all that.
then i downgraded the room back oreo to see if it helped, no luck ;(
changing sim did NOT help either.
any suggestions? i have no warranty left on the phone as it a bit over 2 years old.
Mine is doing the same thing, even with wifi. It started after the most recent update. I have been googling, but haven't found much so I assumed that it was localized to me. I have never had connectivity issues with this phone before.

I am having the exact same issue, it all happened after I updated to android 9, even if you downgrade back to 8 it doesn't fix the issue, has anyone managed to find a solution ? Like henbone11 mentioned suggested sites with fixes from Google do not work. Thanks in advance
I was thinking bad modem software? Is it possible to get a older modemsoftware onto the phone with PIE installed?
Same problem here. Have not done any mods, always accepted the official updates.
Cant make or receive calls. (sometimes can make one or two calls right after restart). I do get text message notifications about missed calls. GSM data not working (sometimes seems to work for a bit but not enough to load a page or use maps.
WiFi and Bluetooth still work for me. so I'm using the s8 with another older phone for WiFi hotspot and calling.
Have done full factory reset, uninstalled all apps aso. Nothing brings it back - phone repair shops say they haven't heard s8 having these problems.
I have the same issue.
One day after I restarted my phone, it suddenly said no network connection. I did factory reset too, didnt fix it. Changed sim cards, still error.
I downloaded a widget that was supposed to turn the cell radio on and off. Cant turn the cell radio on either
Network Connection on s8

Did you get any luck fixing your s8+ network problem?
no, still no network.
have done everything I can without rooting.
Tried different SIM cards and network providers - no luck.

Hi,
This issue is quite easy to fix. As modem performance (connectivity) is linked to model configuration. Another word for this is CSC.
It is fine to change your CSC. Download a benchmark tool to monitor your connectivity and record values and do not feel afraid to update / change your CSC.
It can take a while to find the right one for you, not it will be worth it. Don't worry.
Note: CSC changer can be easily found in XDA.
Note: a restart may be required to take the configuration into account.
Cheers

Hi.. i want to do your solution.
What benchmark tool to use? And is there a tutorial for the process?
Thank you so much for the idea.
I moved to another country and used a local sim card, worked for a couple of days and then it's suddenly no network.
IMEi still ok.
Phone still detects my number.
I've tried
resetting network setting
factory reset
Flashing latest unbranded firmware via Odin
Still no luck.
The mobile radio switch won't turn on.
Ping test fails.
Sometimes I wonder if this is a hardware issue.

Why would this work? Phone worked normally before. Same country/same provider. Sometimes still connects to data network for a minute and then drops all cellular connection again.
Why would changing CSC work.
Asking because changing CSC is not easy for me and I don't see why would I need to change it if it worked perfectly before. NFC payments worked(still work) , data/voice calls worked perfectly for 2 years. Then suddenly didn't.
