Hi, does anyone else have this problem on the latest firmware?
When I'm leaving the house after being connected to Wifi, my phone won't connect to 3G. I have to turn the data connection on & off to get it working.
If I'm going from Wifi to 4G or 4G to 3G it works fine.
I'm running 23.1.A.1.28 UK stock firmware, but the same thing happens on Moonbreakers 2.5. It's not my phone as I've tried 2 different ones and the same thing happens...
Cheers
You can try diferent baseband
im running german version 23.2.A.1.62 and don't see this issue, when I leave a wifi area it automatically puts the data connection on

Whenever my phone is connected to wifi it switches the phones network setting into GSM only. It essentially drops all cell signal. It still works over the wifi obviously, but I'm curious as to why this is happening?
As soon as I disconnect from the wifi, it immediately swaps back to the wcdma/gsm auto.
I cannot attribute it to any apps, or my ROM specifically (ARHD 6.7.2) because it was happening before I wiped and flashed the phone.
I don't think this is normal. Does anyone else seem to be having this issue?

Losing gsm signal when wifi transmitting data
Different kernels no improvement

Same. I tried different Kernals and different Radios as well.
I tried different ril/radio sets. Didn't work
I have to try stock RUU.
Thats normal nothing to worry about keep in mind our devices is infact GSM

I solved the problem. I cleaned contact pads inside back cover with alcohol and cotton earbud. Cleaned also contact springs.
Problem is gone since over week now.

Hello everyone,
I hope someone can help me because I am going crazy with my Optimus 3D My device constantly loses the 3G connection and so I don't get any notifications about new e-mails and Whatsapp messages. The icons for network strength turn white and even sometimes that happens with the wi-fi icon. I already tried rooting the device and installed a custom rom but I still have this problem. The problem mostly occurs in the office I work in as 3g and network reception is very low here. I see that the device switches between HSDPA, GPRS and 3G quite often and then most of the time loses the internet connection. It also does not reconnect when I walk around and get to an area with better reception. Sometimes switching to Airplane Mode and back helps, but this is not a very handy solution. I am really clueless where the problem could be. I am here in Frankfurt/German so normally there should be no problems with the network (I am on Vodafone). The only thing I could think of is my SIM card, because I had an iPhone 4 before and had to cut the card to the micro SIM size and now use it with an adapter. Could this be a problem? Also the app 3G reconnect did not solve this problem.
Has anybody a clue what might be wrong with my device? I am already thinking about getting a new phone
Cheers,
Andreas
Does it do that when goes to sleep?

I don't know when it loses the connection, could probably happen when it turns the screen off or switches between network speeds (3G, GPRS, HSDPA). It really is a problem for me that it does not get the connection automatically back. Currently it shows almost full network reception, the "G" icon with both arrows underneath (only the left arrow pointing up turns green from time to time), but it has no internet connection. I sent me a mail to my google account via my office PC haöf an hour ago, but still no message on the phone, that there is new mail
Just try a new simcard... my guess is that it will solve your problem.. could be worth the couple euros ..

I had similar Problems with O2 in Bremen.
That happens if the phone loses the 3g(h+) signal, turning of the data connection, and let that reconnect is enough, no need to turn on airplane mode than.
Try flashing the newest baseband version, and try the prometheus rom + kernel. I still notice that the same problem happens, but it reconnects again after losing it now, and i rarely notice it that way.
Maybe you could tell us your android version, and baseband version.

I had a similar problem when I used GB roms without upgrading my baseband.

Hi everyone,
thanks a lot for your answers. I have the newest firmware on it V21E and baseband is L6260_MODEM_SIC_01.1042.00. Problem is that it does not automatically reconnect when it loses the internet connection. I had this problem again the whole day. When I left the office for lunch it did not reconnect, so again I did not get the newest e-mails. Probably I will really try another SIM card with a different network provider. I never had this issue with my iPhone... Thanks a lot for the advices, hopefully something will work. Otherwise I need to get a new phone :/
Cheers,
Andreas
For me the 3g data service goes as it likes but to reconnect i have to restart the my phone. Tried many roms as well as kernels and finally using acura 3d Max 3.1 with titan kernel solved the problem. It doesn't give up 3g connection but if i switch to edge and back to hsdpa again i have to restart. Barry also lasts and have overclocked to 1.2 ghz
In the Dailer APP dial *#*#4636#*#* Phone info Scroll Down just above the turn off radio button Change from WCDMA Preferred to WCDMA only
Good morning (at least here in Germany it is morning *g*),
got me a new SIM card with a new provider yesterday evening and so far it seems to work fine in the office. I hope it stays like this, then the problem would be solved *phew* Thanks a lot for all your help!
Cheers,
Andreas
Most of the time it works fine, but if the signal drops I get no internet.
Even if I have one bar signal, the phone tries to connect to 3G or H, which is impossible, so internet doesn't work. I think that when the signal drops the phone should switch to 2G, right?
In settings I have GSM/WCMDA auto checked.
I tried different radios and RILs, but I haven't found a solution. Thx in advance
I was having this issue last night, someone mentioned T-Mobile is having some tower issues. Which rom is it? Is it happening with just one rom or is it any rom? It happened to me running Cm10 then when I switched back to DKOS I got my signal back. I was trying everything also, new rils, ect. The only thing that helped me was to switch roms. Hope you get your data back soon! Maybe try out some different roms to see if it returns.

I am using Viper S and I am in Albania, Europe, so it's not related to T-Mob.
The strange thing is that it doesn't switch to 2G, no matter how low the signal is, it always tries to connect to H. Does anyone have this problems with Viper?
Edit. By testing with different RILs, Radios I came up with the best configuration for me.
It's the first time I get 7MB down and 2 MB up. The max before was 5.5MB up.
But the problem with 2G network is the same, so I think it has smth to do with the ROM
Edit:I realized that it was my networks problem. So if you are on Vodafone Albania it's normal to lose connection once in a while.
But there's a simple solution to this problem. I found an app which resolves the probem perfectly 3G RECONNECT
Hello, I'm using oneplus one A0001, I'm having problem with 3g connectivity, my device majority of the time doesn't connects to 3g, and if sometimes it connects, signals drops. My sim is fine, coz i checked it with other device.
Does anyone know about this problem. Any help will be appreciated.
Thanks.

I have the same issue!
I use CM12 nightly from 20/12/2014 with stock kernel.
I found that rebooting the phone will help but I also have WiFi drops so go figure
I'm having issues with stock rom 11 4.4.4
Hello. My issue is that my phone won't connect to LTE in stock ROM, but it connects with CM 12.1. But my main "concern" is that it used to connect to LTE using stock ROM... To make the long story short: when I bought the phone, it only connected to H, even if I selected LTE in Preferred Network Type (selecting LTE there even made, and still makes my data connection unstable, getting disconnected and rapidly connecting to data network, but only uses H network type) so I selected 3G, because it was made my connection stable.
Then, after some time, I decided to try and select LTE again, and it connected to LTE! Good, fast, stable connection. But after some weeks, I had to wipe my data partition, and again... it would't grab LTE. Some days ago, I flashed CM ROM, and I was surprised that it grabbed LTE with it again. And today, I decided to flash stock ROM again because CM gave me some problems with moto apps (I had to wipe data because it entered in a bootloop), and again, no LTE in stock ROM.
My question is, what can be causing this behavior? I didn't do anything to purposely fix data connection and use LTE, and my phone is capable of connecting to my carrier LTE band (i tested the speed when I was on LTE and yes, it was a lot faster than H), so it should be some ROM/software related issue. I tried to reset APN setting, connecting to the 2 APN that my phone has, and still won't get LTE.
Any ideas of what could be causing this behavior? Thanks!

dial *#*#4636#*#* and service menu will appear. in phone info menu select network type 'LTE only' and check your signal strength. if it's low like 1 bar in status bar that's why it keeps switching back to HSPA.
I won't connect if I select LTE only, it just shows "no service". But I have good signal here in my house, as I used to have LTE when this was working fine.

maybe carrier signal problems? you should check LTE signal strength on other's phone and compare with yours when it's available at your house.
and you mentioned it was working with cm12.1, try with it again or maybe ur harware was defected

Ok, I'll try again with CM again, but it used to work some time with stock too. I think it shouldn't be a carrier or signal related problem, but I'll try using my sim card in other phone, and try again with CM, I'll report back here after I test.
It seems to be caused because of the APN. I inserted another sim card to my phone and it added a new APN, and it changed the Network Type in phone info to "LTE/GSM Auto (PRL)" and now it works! Thanks for the idea!
But I still find it strange that it connected in CM from the start, hahaha
