Wifi bug

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.

Network Mode Toggle

Hello,
When I am at home a have a really low 3g signal strength meaning call quality is very poor or the call does not get through. I really need a toggle to switch to GSM only as this gets me full signal plus I don't need 3G at home as I am connected to my wireless broadband. I bought Tasker but no option available as of yet (I think it will only be for rooted phones when it does become available anyway).
I tried turning mobile data off but it still seems to have weak signal with network mode set to auto. I can do this manually but I would like it to be automated somehow. Any suggestions?

[Q]Force gsm nexus to automatically switch to 2G sooner in low reception area?

i noticed that i get much better 2g reception in my house than 3g so would it be possible to set the galaxy nexus to make the switch to 2g sooner and automatic? im using a toggle right now but it would be nice to be able to set the point at which the phone will make the jump to 2g.
The 3g signal is so weak in certain areas that i dont lose the signal but i wont be able to receive calls and goes straight to voicemail but the annoying thing is that sometimes the phone doesnt make the jump to 2g. Im using the mod in aokp to see my signal in dBm instead of the bars and have found the difference is -111 to -113dBm for 3G and under -100dBm for 2G in the same spot. i would like to be able to set the phone to make to jump to 2G when the 3G signal is weaker than -110dBm for example.

anyone? do we know how the phone decides when to switch to 2g?

Why don't you just keep manually toggling it as needed? Problem solved. That said goto YouTube and watch the everything is amazing but nobody is happy video.
And remember kids. Your smartphone is not a pacifier.

cause it would be easier if it did it automatically like its suppose to. if i forget to toggle the 2g everytime i home then i miss a call in the house? this is a phone we're talking about im not asking for anything special just for it to work like its suppose to.

Exactly. Couldn't have said it better myself. Now I need to go start a thread asking how come my phone won't clean my room. Ç'mon it's a smartphone.

receiving calls and making calls is not something special for a 700 dollar phone. this is the first phone i got that has this kind of trouble switching between 2g and 3g. go troll somehwere else if you have nothing helpful to add.

Seriously what is so hard about manually toggling your phone to 2g at home? I have to do it occasionally still even though 3g isn't the juice sucker it used to be a few years ago. Another alternative is to get a micro cell but I an sure you don't want to pay ~$200 and $20 a month. There are apps that will do the 2g toggle when you're on your home wifi. Nfc tag might be able to do it too. It seems you want somebody to write an app specifically for your "problem".
iphone. helping computer illiteracy become popular since 2007.

you're really not getting it, its not about a toggle and im not asking anyone to make an app so i dont have to use the toggle. im not talking about switching to 2g to save battery or data but when the 3g is weak or isnt there and there is a stronger 2g signal available. i am using a toggle right now but thats not a solution. this is a phone, i shouldnt have to toggle anything to make calls. All my previous android phones stayed in 2g 90% of the time in my house all by themselves.
Phones are suppose to be able to switch between 2g and 3g when 3g is not available or is too weak, the galaxy nexus is not doing that properly it hangs at 3g even to the point where it drops the signal and there's always is a good 2g signal that it should be going to. i have no 2g deadspots in my house but a few for 3g.
i've tried all the radios and they all have this problem some worst than others. i was just thinking if there is a way to mod the phone so that it will switch to 2g sooner or faster

And I am telling you to do it manually to solve your issue. You still want it done faster automatically and nobody here is going to be able to mod a radio for you. Aside from aaaaaaaall the barriers prohibiting devs from doing so, there is just plain and simple the issue of it actually transferring from 2 to 3 and 3 to 2, handshaking with the tower which is not instaneous. Like I said watch that video and get a grip and laugh. The best and fastest solution is manually. I have to do it myself occasionally for different reasons. If you don't like having to do something manually because you have a $700 smartphone then all I can tell you is good luck with the rest of your life.

i looked into this some more and it turns out there is a setting that can do exactly what i want but is disabled in the new 4.0.4 update. in the *#*#4636*#*# menu you can set network preferred type to gsm auto prl which will only switch to 3g if there is a strong signal and will favor 2g. With the new update(4.0.4) the setting cannot be changed and is stuck on wcdma preferred which is the opposite of gsm auto prl, favors 3g over 2g. hopefully this can be fixed somehow so that the network settings can be changed.

I'd stay out of that menu on nexus. It has caused many a problem for gnex owners, one which is it automatically goes back to default setting no matter what you select and erasing smsc number randomly. Toggling 2g in settings or getting a 2g/3g toggle in power control is fastest and easiest solution still.

When connected to WiFi I loose my LTE singmal

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

Does the connection optimizer suck?? Is there one that's actually intelligent?

So my phone's data connection does stuff which I can only describe as retarded.
There are comcast wifi hotspots all over the place here. They can come in handy when the LTE signal is weak or nonexistent. But my phone, through the connection optimizer i assume, will connect to any comcast wifi hotspot no matter how weak the signal is even when there's a full strength LTE signal.
So very often I have a great data connection of LTE and my phone suddenly switches to a hotspot with barely one bar of signal. It even does this when i at home with my own wifi. There's a comcast hotspot near my house, but far enough away that the signal is pretty poor. If my phone happens to see the comcast hotspot as I'm driving home and it connects to that, it'll stay connected to that even though my own home wifi signal is at full strength.
Basically, this 'optimizer' is nothing of the sort. It's a pretty dumb application since all it seems to do is connect to any available wifi regardless of the signal strength of the hotspot or over the cell network - and it never bothers to check if there's a better connection once it's connected to something.
Is there any way to make this app even half way intelligent? Or an app i can replace it with?

You're right; it's retarded. Hint: only use it enabled when you want to connect to that Wi-Fi or the type of Wi-Fi that requires the agreement to terms each time you connect. The Optimizer has shown some convenience where a user may roam between that type of Wi-Fi hotspot and data connection.
Android seems smart enough to remember Wi-Fi with typical login. I was on a tire shop today and auto connected to Wi-Fi without looking into remembered Wi-Fi connections (I left Wi-Fi enabled when I left home; often enough, doesn't interfere with cell data when I need it). I freeze the Connections Optimizer and only thaw it when it seems logical.

from the article there, it sounds like i am having the opposite problem - my phone isn't jumping from wifi to lte, it's jumping from lte to wifi even if the wifi signal is crap.
