Hello all,
I have faced issues with the Wifi on my OPO since the day I got it. I researched a lot about it and found out that it's a problem faced my a lot of OPO users. Just to summarize the problem: The Wifi connects but after a few minutes (in sleep and sometimes even when the phone is in use) the data transmission stops. The Wifi icon shows that it is connected but you can't access the internet.
I had this problem on the 11s and when I read 12s had solved the problem I moved to 12s. But the problem still persists. Here are the things I have already done:
Wifi in sleep - Always
Restored factory settings
Installed app WifiKeepAlive
Installed 12s (15th Aug build)
I have seen a lot of posts but haven't seen a resolution in them. Appreciate if someone could help out.
I used to have a similair problem on my old One until it broke due to water damage. My new one doesn't have this however.
Perhaps a kernel issue? Try flashing a different one and see if the problems persist.

Hi people,
I'm opening a new thread because I have not seen a post about my kind of data drops here and couldn't find any by searching.
Thing is, since switching to Cyanogenmod 9 my data dropped. However these drops are kind of "invisible" because the system bar shows H/ G/ or else, but download/ upload arrows show only sometimes and if they don't, there's no data transmission. So I have to wait all the time until finally the system seemingly randomly decides to download stuff although there is a H/ G/ ... shown.
It worked with stock ROM and Bulletproof, but this issue arose when I flashed CM 9 and also persists with CM 10. Only thing I can find that looks like it can be similar to my problem is this thread: http://forum.xda-developers.com/showthread.php?t=2034998
Today I updated my radio finally, but still no change. Checked APN settings, everything seems to be fine.
Any help is greatly appreciated.

Have you tried changing your APN settings to a different one? I've had similar issues with CM to what you're describing, switched to internet2.voicestream.com, haven't had many problems since.
i had the same problem before and i called t-mobile and they took me thru step on reconfiguring the step so now i can talk and surf the web at the same time try that but if that doesnt work try reflashing the rom again
I've just been lucky and it works with CM 9 this time and continues to work through new flashes of CM 9. Well... Sadly I don't know what went wrong, but it works now
Still want to answer you guys for archival purposes and if someone looks for a solution... and thanks for replying, it means a lot to me!
I live in Germany and imported the phone, it hasn't been sold here. So I can't ask for technical support.
I looked after the APNs but they were already the ones described as by my carrier.
So... Problem solved... for now. And thanks again!
This happens on every Lollipop ROM I have flashed, no problems on 4.4 ROMS. I do clean installs, do not restore anything from Tibackup. So basically what happens is I will randomly but very frequently lose all data and cell service. Like once every three minutes frequently. It only lasts about 5 seconds at a time. The signal bar triangle will have an exclamation mark in it (see attached example). I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option. I have read some threads about this exact same thing happening on Nexus 5 after Lollipop update but they are old and it seems to have been fixed with an update. Does anyone have any ideas about what is going on? I'm on TMO in the US and like I said, it ONLY happens on Lollipop ROMs it does not happen of Kitkat.
I read this as sort of an explanation as to why but nothing as to how to fix it. It is driving me insane.
I'm in the same boat, I cant make calls with hangouts or with Dialer or it will disconnect. I haven't seen a solution yet. I've tried every ROM I can, but it keeps crashing. drives me up a wall. I want to logcat it, but having issues while at work.

Only discussion about this I have seen is in the Nexus 5 forums, nothing in OPO
Any insight to this would be greatly appreciated.
Come on guys, am I really the only one with this issue?

You're not alone, I have this as well but I don't get the exclamation mark but instead the triangle appears completely empty, as if I have no signal at all.
anyone know a way to fix this awell? i flashed the new lolipop alpha modem and still same thing if not worse
The only time this has happened to me is when I toggle Wi-Fi. It for this every time, but have no data issues otherwise. Seems to be when switching between ip addresses. Are you possibly between towers or roaming on another network? May be the issue, but I can't say for sure. Running the lollipop rom exodus, no issues at all.
EDIT: also what baseband are you guys on? I thought I saw something similar and someone flashed a test baseband and it fixed whatever issue they were having. Link coming shortly.
EDIT 2: just now noticed the list above mine about the alpha modem and it not working for them. If anyone else needs to try however, link is http://forum.xda-developers.com/sho... work for some and not others.

Does anyone know if we can flash the CM11S modem on CM12?
Go to Settings -> More - > Mobile Networks. Make sure all the items are set correctly.

In OP "I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option."
Same issue here. Running SlimSaber using alpha radio.
Same problem on two OPOs here, both running Temasek CM12
Anyone found a solution yet?
I have the same issue on CM12, BlissPop and Validus ROMS.
Strangely I do NOT have the issue on Euphoria.
Think it happened after I flashed the Alpha L modem.
Tried flashing an older CM11S modem, but no luck...
Hi,
Sorry for the noob answer but anybody tried settings>mobile networks>preferred network type and set it to 3G? I flashed a new rom from stock CM and noticed that I was experiencing signal trouble, I checked my status and the signal detected is LTE so I changed my network to 3G and network signal improved. Downside is that you cant use LTE (but thats ok for me since here in our country, LTE signal is still kind of limited)
Zino same for me. Ever find a fix or a rom that doesn't do this?
OP here, it's strange that all of us have this issue, the same issue that came up on the Nexus 5 thread when L was first released but know one else seems to have any knowledge of it. I am almost certain it doesn't have to do with our carriers but rather something software related.
I'm also suffering from this issue, until now the only way I knew how to fix it was to wipe the cache in recovery which takes ages!
got the same problem :<
I have a similar issue. I use t mobile in the USA and LTE works, H+ works, but 3g shows signal and won't load anything. No idea how to fix it.
It seems I have managed to solve it by myself. I have loaded factory image of 44S, preformed OTA upgrades and it seems the issue is gone.

Hi, Last week I had my phone connected to power bank over night with "Sleep as Android" turned on. In the morning I got my wake up alert but I was unable to wake up my screen to turn it off... so I had to keep the power button down and shutdown the phone.
After that I have faced boot loop (phone worked fine previous evening).
I have tried rebooting phone couple of times but nothing worked so I have restored backup of last CM11s from TWRP (I was running on CM12 nightly during the crash). Phone booted up poperly and I thought everything is fine however after couple of hours I noticed my phone is asking me for my PIN so it has apparently rebooted. It appeared that it is rebooting every couple of hours and after every call (like 5 sec after call ended)...
I have tried restoring other backup but I was facing the same issue. I have done clean install of current CM12 nightly and got the same...
Facing that I decided to clean my phone completely... I have backed up all my data and did wipe and format of everything of everything I could from TWRP. Then via fastboot I have been tring loading YNG1TAS17L 64GB (from here) by flash-all.bat file. After loading bootloader I have received message <waiting for device> and my phone got hardbricked...
I managed to recover it using this guide.
Then I loaded TWRP again and installed COS 12.
On that point my phone started working stable but after a while I noticed that is started losing cell signal. Sometimes it was just for couple of seconds and sometimes it lost it for good (while tring to hardcode cell operator I was getting "error while searching for networks" and I was able to restore connectivity after couple of reboots).
I decided it could be radio/modem related so I have applied full firmware. No go. Loaded CM12 nightly - the same, loaded that modem from oxygen again - no go.
I have tried installing latest BlissPop, Mahdi ROMs and Oxygen and still facing the same issue.
Tested SIM card on other phone and it works fine, tested other SIM card on my OPO and still the same issue so it is phone related.
Getting the following in logcat during time phone is unable to connect to cell signal:
Code:
05-31 11:57:36.265 D/GsmDCT ( 2457): [0]isDataAllowed: not allowed due to - SIM not loaded and not NV subscription
05-31 11:57:36.265 D/GsmDCT ( 2457): [ApnContext:mms] getApnSetting: apnSetting=null
05-31 11:57:36.268 D/GsmDCT ( 2457): [0]isDataAllowed getRecordsLoaded=false
Anyone has any idea what could be a reason of this issue and how to fix it? At this moment everything is working fine except phone calls and Internet over network operator (Wifi works fine). Thanks in advance.
UP
Anyone has any idea? I believe I have narrowed the problem down a bit. It seems 2G/3G is affected only. As long as I'm in LTE range the connection is stable (that explains why I noticed the problem after few hours when I left home).
I have played a bit with hardcoding band and noticed that LTE is running stable (with GSM Signal Monitoring app). When switching to 3G it is dropping every couple of seconds. The strange thing is that 2G is sometimes affected and sometimes not... When switching LTE->2G it seems to be running pretty stable but when switching from 3G->2G it is acting the same way as 3G.
were you able to fix it?
I went through same experience except that I can barely connect to 4g, 3g 50% of time. Tried many radios but none worked.

OP updated the post with how it was fixed. Sorry to bump the thread, but thought I'd inform spx that there was an update. Glad it worked out for you OP, I've saved this in case it ever happens to me, and good luck to spx. Hopefully someone puts this info in a sticky so others can try that if they are stuck too.
I fixed it by reflash raido of xnph52q found here. The zip contains more than the radio firmware.

I flashed it before but it didn't work. The only difference is I used TWRP 2.8.6. I remember reading somewhere online that 2.8.7 has issue with OPO

Where is the 44S that OP used? I have something similar happening with my phone. I revived my phone from a hard brick and now it's not connecting to the cell network. Wifi works, IMEI shows when SIM is inserted, no EFS partition backup (I didn't know that was a thing to do until it was too late).
FWIW, my current build is KTU84Q and I'm running CM-11-20141008-SNAPSHOT-M11-bacon
Hi,
I have serious connectivity issues with my Nexus 5.
Most of the time I am only picking up 2G signal, sometimes the connection drops compeltely. However, I had a very unstable 3G/H/LTE connection for a few minutes sometimes in the last days.
This started after changing the battery and upgrading from Cyanogenmod 12 to 12.1. Unfortunately I did both changes at the same time, so I am not sure what caused this problem.
The following things I could rule out/test:
- Another phone (Nexus 4) picks up H+ with my sim
- My phone doesn't pick up 3G/H/LTE with another (working) sim
- I have checked the connections of the both cables running alongside the battery, I also checked the cables itself.
- I fiddled with the apn settings, also I never touched them before and everything worked fine.
- I have updated the radio image.
The one thing I couldn't try is flashing an older cyanogenmod 12, because I have no backup and couldn't find one online.
Does any of you have any ideas what I can do?
I would be really thankful for any kind of help.
Who is your carrier :/
I probably should have added that in the first place.
My carrier is T-Mobile in germany.
I have the same problem. Also i'm tryed flash Android 5.0 and Android M, in stock i have Android 5.1.1. Who khow how to fix this ?
I have no solution yet. The next thing I want to try is to roll back to Cyanogenmod 12, but I guess I am going to build it myself because it seems to have vanished from the internet.
I do occasionally get LTE, but it is very unstable and doesn't work most of the time.
Hi, guys.
Some time ago, I made a post here talking about a wifi problem that happened after I installed a custom ROM on my Surya (for those who don't know, my wifi keeps disconnecting and connecting when I use ROMs that wasn't made based on MIUI). Sometime later, I reinstalled the original ROM via Mi Flash, as I was told to do. For a while it worked, but one day I turned off the wifi (I was going to school, and the wifi connection there is horrible, so I turned off wifi cause I wasn't going to use) and when I turned it on, it stopped working. Since then, I've been trying to do everything I can to get back, but nothing works. I've already spent the stock ROM on Mi Flash several times and even then, the most I could do was to make the internet work for a few days and the problem again. Does anyone know what i can do?
At first I thought it was a firmware problem, by the way, I'm suspecting it's a problem with the modem itself, but overall I don't know where the problem is yet.
