Hey guys,
Is there a bug since the last OTA update with the wifi not letting the 3G connection access data when wifi is on? Seems like I have to turn off wifi for the 3G to pull data.
Its not an issue when I have a strong wifi signal, but when its weak, or non-existent, the phone does not seem to switch over to the stronger 3G signal.
It was definitely not like this before the OTA.
Thanks in advance for any advice!
I am pretty sure when you are connected to wifi, it kills the 3g because the wifi can replace any 3g data connection

It has always been like this, wifi will always overwrite 3g

I understand that wifi is a faster connection than 3G, but when there isn't a wifi connection, or there is a super spotty wifi signal, the phone doesn't switch over to 3G anymore.
hmmm. I am pretty sure mine turns off when when I am out of range. But if I am still close to the router it kinda poops out and sticks on wifi. I will check when I am out later.
The only suggestion I have is to put a wifi power widget on one of your screens to easily switch off if you are on a spotty network

yep, that's what I've resorted to doing for now. I'm 99% certain that it wasn't like this before that last OTA update. The only reason I ever had to turn wifi off before was when I was using my bluetooth headset.
Here is a little test you could try. IMO it should check to see if you dont fall back to 3G when you lose wifi signal.
Have wifi turned on and connected. Go to setting-wireless & networks-wifi settings. Where it says wifi network press the network you are connected to and press forget. This will disconnect you from that network and it should fall back to evdo. If it does then it is working properly.
hi people
i'm noticing a problem with my data/edge/3g connection.
it simply stops working at times .. it just shows data being sent but no data received and my internet doesnt work.
This becomes fine after a reboot but again has a problem after a few hours
Is anyone else facing this problem too with Data connectivity ?
Yes, same problem with my german arc.
I am not facing any problem with data connectivity
same problems here, I found that stopping the WIFI and re enabling it is enough to get it back on track but its still a serious issue.
I don't like finding out I am missing e-mails an hour too late.
I only found it happens when I switch from 2G to 3G with data on.
So my work around is to turn data off first before switching between 2G <-> 3G. After that, turn back the data on.
This only happens to me on WIFI, on 3g everything is fine.
I am thinking about flashing the UK build to see if it helps.
I used to have the same problem with my x10. Data just stopped working randomly. I used to have a widget to turn 3g on/off and when the data stopped working, so did the widget. Was strange, and only a reboot solved it.
I have wifi problems,it sleeps after a while,no sleep is selectet.

i have wifi problem, at first it disconnects by itself and now much worse, my arc could not even identify or scan my wifi at home. Anyone also have this issue? or anyone know what to do.
One time i had this issue,i had just turn wifi off then on.

same here. wifi works fine. til awhile later (evactly how long i didn't notice. will keep track)
After which no matter how i turn off & on wifi, forget the network & re-enter p/w. even off & on my phone. wifi status "connecting.... disconnected....connecting.... disconnected." will drains off a lot of battery if go unnotice.
i found a cumbersome work around... off the arc wifi & reboot modem/router. then can "obtaining ip address". but thing is, all other devices works fine.
so is it arc's fault? since all others can connect to wifi except arc
or
router's fault? i wasn't doing / changing setting on the arc. just reboot router. but wouldn't it be silly to do this everytime i use wifi on the arc?
so still no fix? sometimes it happens to me a few times during an hour...
Guys maybe this will help you out..
Go to wifi settings, press menu button->select advanced->under wifi sleep policy, set as never sleep
If not set the wifi shuts down to save battery.
And wifi is given more priority over 3g or 2g connectivity, so if you have wifi on you may not have proper connectivity to 2g or 3g
Turn on/off airplane mode, if you can't get a data connection. In a german forum some guys discussed about issues with multi-sim-cards, but I guess it is software related.

i changed my number and sim a couple of days back. with the same provider. my arc after being out of signal cant reconnect to the data network. the phone calls work fine. but the data is giving me problems. im still confused as to why this is happening. whenever i activate and deactivate the airplane mode, data connection comes back alive. could it be a problem with my sim or the phone radio?
edit: oh and i also reflashed my phone via sony ericsson update service, the problems still there.

Same problem here. This is really frustrating.
I dialed *#*#4636#*#* then phone info and pressed menu. Then I selected enable data connection (was disabled previously). The data didnt enable then. I went to settings>mobile network and enabled data from there too. Ever since, no disconnections. I dont know if this procedure or the fact that I tried to seat my sim properly worked, but u may try either. Let me know if this works....
Edit2: the above doesnt work.

I inserted my old fat sim and recreated the situation, the data automatically reconnected. The newer sim that's a microsim is causing the problem.

Hi,
Usually i have wifi enabled permanently, as i have coverage at home, university and t-mobile hotspots. But my nexus sometimes does not get a working data connection if i disable wifi or come back from flight mode. Icon shows reception and 3G/H/H+ but stays grey. I can't access any internet services like mail,http...
If i reboot the device, everything is fine.
Any ideas ?
Latest (-3days behind max) CM10 with stock kernel, XXLF1 baseband, tmobile germany
P.s.: tried to search with google, found nothing. Currently the nexus is my only internet-capable device, so i am sorry if repost...

Try toggling airplane mode?
Beamed from my Grouper.
Same issue here. Get random signal losses and afterwards no data until reboot. I've experienced this with other Roms as well. Toggling the airplane mode sometimes help for data recovering.
Try setting your minimum CPU above 500 Mhz...
How can that change the signal issues?
Maybe toggling wifi helps (sometimes)

I have exactly the same problem on galaxy s. The status bar shows mobile network connection, but the symbol stays grey, and connection is not there. Reboot is the only safe way to solve that. Sometimes toggling airplane mode helps, last time toggling wifi helped.
Changing APN seems to be helpful. Someone that looks good with the current provider.
almost same issue for me...
but there is some weird difference...
I have a GSM Galaxy Nexus latest radio, consistent RIL and latest CM10.
I lost data suddenly while browsing.
I can see blue signal with 3G, start browse and it change to H/H+. No problem until now but, when data returns to 3G, all further requests stay "pending" for a while (phone call is not working in this state!!!!). after a minute.... CRASH, all signal lost. Something like a reset.
even toggling data does not work... I simply have to wait that the phone decides to work again.
I'm from Italy, carrier is Vodafone. Someone with some hint?
thanks!

Because on earlier builds of some AOSP ROMs, the radio had a tendency to go to sleep and not wake up when the frequency dropped too low. The common fix at the time was to use a higher number for the minimum frequency...
Read you must...
I was looking up the answers to this same problem. When I'm staying still my internet is fine but when I'm driving down the road I lose signal. I did a google search for "cm10 losing data connection". This is a "normal problem" it is caused from changing between 3g and LTE 4g. I'm still looking up solutions to this problem.
I have the Note 3. And everytime I connect to WiFi my cell signal goes from full LTE signal to nothing. If I turn the WiFi off my cell signal comes back.
I have WiFi calling turned off - Can someone please help me with this.
Thanks

Some phones do this and some do not. Mine did it on stock but when I flashed Jedi it no longer did that.
You can install the X posed framework with Wanamaker module and enable the 4G let icon all the time. That's what I do.
I would have to assume the radio goes into a lower power mode when WiFi is on. Do you really need your radio to tx/Rx full blast when on WiFi? Just because no bars are showing does not mean you don't have signal. I have wondered about this myself, because often this phone and others have exhibited the same behavior. Checking your signal manually always assures me that my radio hasn't shutdown. You don't need LTE anyways as there is not voice over LTE and I would rather have it downgrade to umts which I am sure it does. I do wish there was an option to over ride this for those rare moments you are expecting an important phone call but at the same time I am not that insecure nor do I let technology rule my mindset like that.

Forgot to add that when you do not have any signal you get the no signal circle which is rare when I am in a place I know I have good signal.. And when you see no signal in a place you think you should have full signal often times there are the other variables to consider.

I had the same problem and people made fun of me on here and said I didn't set my wifi calling preferences properly. Well, I did, and I'm sure you did too. The only thing that fixed it for me was flashing a custom rom. Both custom roms I've tried fixed it (MyRom and Wicked). Bug in the T-Mobile Rom if you ask me...
I'm on Tmobile and I'm having the same problem you have. I lose 4G LTE when my wifi is on. Wifi calling is off because of the caller id issue with oli or ;63, but that still occurs even with wifi and wifi calling off. It's hard for me to make a call on wifi since it will keep trying to redial with no reception. I always have to turn off wifi just to get my bars back and go on 4G to make a phone call.
It's pretty irritating if you ask me; hope either Samsung or Tmobile will make a software update asap.

Why do you want LTE on if WiFi is on.
When both networks are enabled then you are attached to two IP networks.
How are you going to make your IP traffic route if it is attached to two different networks?
I'm not saying it can't be done, I'm just saying that is the way it would be designed to work I would think.
There are definitely tools out there that show that they are not both active at the same time
I'm going to interject on this subject because it is annoying as hell. First of all I have the same problem, but when I'm connected to wifi, my cell signal drops to nothing and if I'm on a call I hear nothing but choppy voices and the calls always drop within 2 minutes. It may put the cell radio into a low power status but it also makes making or receiving calls unbearable or even impossible on wifi. I use a data on off widget and when I'm not using my phone I turn the data off, so this is not remotely an issue with me. My ability to talk on the phone is a huge issue and cell signal drop for me has caused me to never connect to wifi on my G-note3.
Sounds like the WiFi calling bug. My cell signal is terrible at my apartment on WiFi so I have low signal issues regardless. I have no problems in other places when connected to WiFi and making phone calls. I am on at&t though and do not use WiFi calling.

I had the same issue with my first note 3. I went back to tmo and argued It the no signal issue. It showed no signal when wifi was on but the cell was preferred over wifi calling. Turned off wifi signal, on no signal. Then after a few minutes the bars appeared back with wifi on. The manager came and told me that's normal for the bars to disappear. I said No Way Because they were there yesterday. But she said it's normal with wifi on I said I don't use wifi calling be I have good signal in house, But Need It on for browsing. She that's how it is I said bs, so I looking at my phone and I see no signal bars unless I turn off wifi or use wifi calling. Don't think so. And they only way I can check for signal is when I'm on wifi is to call.. No way. She said it's not a phone issue but a tech issue. I said it's the phone why was it on for the last 13 days ago now gone with wifi on. Finally she said she would exchange it. All this bs and she is my friend too. Now my phone doesn't have the issue but has rebooted by itself once again. I knew it was coming because the phone just froze on the flip app. I like Android and it's features, but damn I mess ios's stability.
Have you all checked your status when on wifi?

It's not about LTE and attempting to use data, it's that you lose all cellular coverage so you can't make calls. Even if I'm getting 100% of my data from my wifi, I still need to maintain a connection to the mobile tower to route calls (with wifi calling disabled, which I immediately do because it's unreliable and sucks).

Do you have a screen shot of it?
I assume when on Wifi and Wifi calling off, 4G LTE is not on because it's primarily on Wifi but you have signal bars.
With Wifi on and Wifi calling on, again the Wifi icon over takes the 4G logo. But the signal bars are down to zero because your using Wifi signal due to Wifi calling.
Just because it doesn't show signal bars doesn't mean you don't gave signal. Your dBm and asu trump bars.

I see his pic in the first post now.
I also see how I misread it.
There are 3 separate Radios at least that we are talking about here.
I think the OP should check this setting.
Settings >> Connections >> More Networks >> Mobile Networks >> Network Mode
Then tell us how it is set
Same issue here with Wi-Fi calling off and Wi-Fi on. I think it's just a bug with the signal meter.

Not sure what I am supposed to be looking at? The mobile network state? Mine also says disconneted when Wi Fi is on. Although my cell bars do not go down when I turn on Wifi is still says "disconnected". What does it mean? I tried calling my number it still receives calls.

Do you have any trouble making phone calls when you turn on wifi?
You may want to install "Network Signal Info" or some of the Network info tools and examine your signal levels with and without Wifi to see if these is any change.
"Network Signal Info" is a little buggy BTW

I'm having this strange issue that I've never before seen on Android. Whenever I'm connected to Wifi, the phone seems to maintain a mobile data connection. Also, I'm on T-Mobile with wifi calling enabled, and it seems to stick to the cellular network even with wifi on. Am I the only one?
Ive got something similar, my battery stats show Wi-Fi is on even though its off. Rebooting the phone sorted it out.

My M8 does this, so I would expect the M9 to do this as well. However the mobile data is not used; the icon for mobile data just stays up. It passes data on WiFi when a WiFi connection is available. The WiFi icon is the only one that comes and goes.
I have unlimited calling so I don't use the WiFi calling, can't comment on that.
My mobile radio stays active even while I'm on WiFi calling. Which, I'm pretty sure the mobile radio should completely turn off..
Mobile data icon stays on as well even without wifi calling, same as you.
I think the stickied mobile data icon is a non-issue, but the fact that it sticks to cellular network, pointlessly draining excess battery (especially in a region with poor network connectivity) when Wifi calling is enabled, is seriously annoying.

Both settings are unchecked, like in your screenshot.
Just got mine too.
Am noticing the same problem. Mobile data stays on.
Hopefully there is a fix coming out?
Figured it out (For T-Mobile WiFi calling variants only)
Go into WiFi Calling settings (there should be an icon in your status bar)
Select the bottom "Do not use Cellular". This will disable cellular when WiFi/WiFi calling is enabled.
Cellular was enabled for calling handoffs (when you leave a WiFi calling area, the call gets handoff'd to the network)

Nah. That solves nothing. I don't want to be disconnected when leaving Wi-Fi. I just want cellular to be off when in Wi-Fi range, which was automatically managed with the same setting on previous phones.

Correct, all that setting does is completely disable cellular. Even if you leave Wi-Fi, or disable it.
On all previous T-Mobile phones with Wi-Fi calling using "Wi-Fi preferred" it would completely disable the cellular radio.
Now, when I have poor signal but am using wifi calling, my phone is constantly searching for signal. Switching between 2g/4g/lte.
Yeah, you guys are correct.
Left home this morning, no Cellular.
Well, shoot...
