my wifi, have an E icon, is that correct?

so i enabled wifi, but how do i know i'm really using wifi and not 3g if i see a small E on top of the bars? it seems as if I can not turn off my data connection if i have wifi on..is that correct?

as you may know the "E" is 2g not 3g. When it is 3g it will say "3g" or "H", "H" being faster than "3g".
your wifi goes into "sleep" mode when not being used, helps on battery life, when your phone demands a connection it will take the wifi out of sleep if try to connect and if it does you will see the wifi icon, and if you are not an area that has wifi it will revert back to your data connection.

that's very odd because i have never seen the H ever since i flashed the rom, but the 3g setting is set to be 'on', but that setting disappeared and i dont knkow how to get back to it. is there a way to turn on 3g?

Not always.
AT&T purposely does not show the H and always shows 3G even if it is a HSDPA connection.

since i flashed w/ a new rom, there's no more 3g icon, but i did figure out how to bring the H back, but for some reason i have no idea why my wifi isn't working. someone told me to disable proxy, but i did that

that is true on a stock ATT ROM, but if you flashed a custom ROM it will display correctly

have you tried going to settings>wifi> click "turn on Wi-FI" select wireless networks and see if you phone detects any networks? If there is a network available then select it and set it up.
did you hard reset after you flashed?

No 3G signal after getting off Wifi

Just curious if this happened to anyone or is it just me: most of the time I'm connected to wifi to save battery (home, school, etc) and when I'm out of range it should automatically connect me to the 3g network but it's not. I check settings and 3g is still enabled. Anyone know why?

I am also experiencing this. This happens to me when I am connected to WiFi with bad or no signal but then when I turn off WiFi and go to a good signal area it still registers no signal until I restart my phone then all is fine. Definitely a major bug.

ive had 2 of these phones, ive never had an issue with this. eh. maybe im lucky

Any solution to this?
Ever since I purchased this phone, I hardly get 3g signal. Will a hard reset fix this problem? I have to go by 4g or wi-fi on this phone for data.

having wifi on will actually kill your battery more because you have another radio running, thats why they give you the option to turn it off. (to save battery)
hmm thats odd though mine turns back on just fine
try a hard reset.
its deff a software issue

Wrong, having wifi on saves power because than your phone doesn't have to ping and search for cell towers

+1. Wifi Is definitelya battery saver. I leave wifi on all night at home. I get great battery life. I also never have the problem with 3g either. It always comes back even if I lose wifi signal.
The Evo3D Killer!!!

I noticed this in mine, so I went to Settings->Wireless and Network-> Mobile Network Data and then unchecked 3G and re-checked it and it hasn't had the problem since. Try it and report back.

a lot of users are having this issue along with low speed results on 3g, I read on another forum that Samsung/Sprint are working on it but I'd take that with a grain of salt. I fixed the radio wake up issue on my phone by doing factory reset and then going through the hands free activation again. Haven't had it since.

i'm having this issue too. Turning off wifi, or every time I go in an elevator and loose my 3g signal.
The strange thing though is I had this same problem with my OG Epic for the last two weeks I had it. I flashed back to the current Sprint rom and still had the problem. It was actually the reason I bought the Epic Touch on day 1.

I too am having 3G connection problems
My work is located a mile North of the 101 and Scottsdale and I can't get signal in my building, even if I walk to the big windows.
Of course Phoenix has no 4g so Im S.O.L.

When on Wifi, cell signal switches from 4G and I lose all bars

So when I'm on wifi in my house, my phone appears to switch to edge or something and I lose most connectivity (goes from 4 bars to none). Enough to initiate a call, but simple head turning will cause me to drop. If I turn off wifi, I get 4G back and full bars and no dropped calls.
Wifi calling is too inconsistent to rely on, and this basically makes my phone unusable. I don't want to keep wifi off, as it's a lot faster and I only get 2.5Gbs of high speed data to use a month.
I'm also in the middle of a major city with great coverage 4G coverage, as long as I'm not on wifi....

If you go into your wireless settings, you can uncheck Wifi Calling so that if you do connect to Wifi, you will retain your regular amount of calling bars.

I appreciate the response, but I've already had wifi calling off.. because that feature was basically useless (could not rely on it ever).

My wife Note3 got the same problem, set cellular network preferred and then turn off wi-fi calling. Lose all cell signal bars. When no cell signal, caller ID became funny, like 718-123-4567;oli=63 212-123-4567;oli=00, had no idea.
My own note3 had the same setting, but everything fine. full cell signal bar. Try to google it, no glue!!!
Then I returned my wife note3 and get another one, everything fine.

I had the same problem. When I was on wifi I had no signals. I got a new sim card and the problem is now gone.

i dont think thats the issue, and why do you care because if you call someone it should be able to call and once you need to switch back to tmo it will w/o issue.

Uhh... it certainly doesn't switch back to t-mobile without issue. I drop the call. I haven't had a single call work the entire time while leaving my wifi on in my home.
Clearly, when it's on wifi, even if you have wifi calling turned off, it switches to some other network specifications, which appear to barely work where I live. The problem likely lies in the fact that when you turn wifi calling off, it does not switch your cellular network preferences back to normal properly, Instead, when wifi calling is off and you're still on wifi, it just doesn't route things through wifi, but doesn't actually change your mobile network settings back properly.

well here's a question do you leave mobile data on even though you're connected to WiFi? As i have no problem because i have bars even when connected to WiFi because i leave mobile data on and have WiFi calling turned off. even if WiFi calling is turned off, and i turn WiFi off it switched to T-Mo network in seconds and i'm able to call someone so yeah no issue. you clearly have a problem with something or its the network where you live.
i'm not trying to be rude but it just doesn't make sense to me that you're having issues with something that shouldn't be a problem.

This doesn't actually work currently on the Note 3. there is a bug where any time you have wifi on the cellular entenna turns off regardless of the state of your wifi calling on a very large number of Note 3's. Lost Soul clearly hasn't been reading on the threads here. there are many on this topic. We get that you don't have the issue LostSoul, but that doesn't mean it isn't an issue.

Thanks Hughes,
I have found that when it enters that state, that if I go and turn wifi calling on and then set it to mobile-network preferred, it turns the cellular modem back on, at least for a little while. Can you point me in the direction of a more robust thread where others are discussing the issue?

I've flashed a rom as well and it appears as it might be fixed... hope so.. my phone is useless if it can't function as a phone while on wifi.

I had same issue. Called TMo and had them unregister my wifi calling, and got bars back immediately. I had wifi calling turned off, but it seemed to be the default regardless. I could only receive and make calls with wifi turned off...but it all works fine now.

That didn't work for me

I called Tmo four times and asked them to unregister wifi calling. They said that it wasn't even turned on for my account then that it doesn't matter what is or isn't turned on. The phone is going to run calls, text over whatever wireless connection it thinks is appropriate. When you have a strong wifi connection, it chooses that connection regardless of wifi calling being turned off or on. I set the wifi calling preference to cellular networks and it still does the same thing.
I'm pretty pissed off about it. Anyone fix this?

Not true. I shut off Wi-Fi calling on T-Mobiles site and bars came back. Had the exact same problem.

When connected to WiFi I loose my LTE singmal

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.
sent from my sm-900t.

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.

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.

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.

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.
