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.
So for some like myself, COS 12 wifi has been behaving sporadically. I would surf the web for 5 min only to have my internet connection crawl to a stop.
Turn out that COS 12 and CM 12 have an issue where the dhcpcd sends incorrect values to the DHCP servers.
The disconnect is not apparent on all devices! It depends on your router's settings.
So, with special thanks to Tony Stüker, I have made a flashable zip of CM 11s dhcpcd file.
If you experience the aforementioned issue, BACKUP your system and then flash the file below.
Download (Enjoy!)
PS. Flash at your own risk.
I definitely support the CM11 05Q modem. Fixed my issues with WiFi delayed messages a s calls. Also so far has fixed notifications for messages not pushing though whether on WiFi or not.
Thank you mkhcb, I confirm this works well. Now I just need for someone to fix this f......ing bluetooth. Mine keeps crashing every 15 seconds since 4.4.4.
Thanks a lot! This helped me to solve my connection problem with 6D!

Anytime guys.
Also, I am sure we can get the Bluetooth fix if others report bluetooth problems.
Any issues with cm 12.1 with the fix?
Hi pal,

your help is appreciated.
thank you in advance.
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.
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
Was running on the CM 12.1 and no issues with wifi. Then I decided to update and went with the RR per below
http://forum.xda-developers.com/oneplus-one/development/rom-ressurrection-remix-m-t3270147
Did a clean install and loaded gapps and everything seemed ok but then had issues with Wifi dropping constantly. I tried google and changed channel on router to channel one and also tried app called Wifi Analyser but still the same issue.
Saw a fix for cm 12 in the below
http://forum.xda-developers.com/oneplus-one/general/fix-wifi-connectivity-issues-drops-t3070045
Not sure if same fix applies to 13 as it seems to be an issue with the CM 13 and not the ROM itself..??
Had to go back to CM12.1 and no wifi issues pity as was happy enough but no wifi is a showstopper. Posted in the RR thread but maybe this might be a CM13 issue so wondering if anyone knows any fixes for it as I may try again
Thanks
I have the same issue, need to turn off bluetooth, try it it may work for you also
