[Q] [Troubleshooting] 3G network problem

Hi guys
I have problem with 3G connection through application, but wifi is fine. All that I can do through 3G connection is go on a internet browser and surf. But if I open some application which uses the internet so do not connect..
How I said through wifi is everithing fine, but through 3g is not.
I tried wipe, factory reset and clear cache from but nothink helped...

Goto -> Settings -> Wireless Networks -> Mobile Network -> APN
Is there anything there?
If there is find the settings for your carrier and double check them

re:
Yes, of course there is configuration for 3G work... I said in a internet browser I can surf, but I can't use internet through apps as gmail, market etc...

Can it bee that the network provider has somesort of problem with the network or the gmail and market servers they are using is down. Once i have gmail problem but that wasn't the phones fault The server Google used was down with somesort of problem. Must say that strange problems ppl has with they phone if connection via wifi works but not 3g? Then it must be fault in settings or fault i the network.

I do not think that, because I have this problem around 1-2 months

So you can not connect via 3g at all from application?

Ok if you can use the browser and it works the setting/ access point is right. Very strange problem indeed

Yeah a little bit :-D
1.yes I am sure
2.you are more smarter
3.because thats same problem have many users
4.I am not crying bro

I have a similar problem.
If the phone is only on wi-fi connection, gmail, internet, market, daily briefing (accuweather) and maps are working fine. If I switch the wi-fi off and switch APN on, only the market works.
how's that?

Thanks for the reply !
Is APN access point names?
I have only two options there
-postpaid(e-ideas)
-prepaid(hicard)
My telecom is singtel from singapore

I've had this happen, a quick airplane mode onn/off worked (takes 10 seconds).
still annoying though.

I had the same problem with LG-P990 and unfortunately I did not find any fix.

Wifi disconnecting problems..

Is anyone getting the wifi problems that the other versions of the Note 3 are getting? Preferably when it says the network was disconnected for being too slow or something like that? I know it happens on the T-Mobile, Verizon, and International versions.

Mine doesn't disconnect but it says wifi signal is unstable, then I looked in settings when this happens and it says wifi signal strength VERY STRONG, I'm sitting 10' from my router and I know damn well the the signal is strong as it says 72mbps. Lots of issues with wifi signals are popping up in the N3 sections, not good.

Yep, same as Quickvic30

Go to wifi advanced settings and uncheck Auto Network Switch. It appears the phone will "test" the speed of the wifi network to your 4g and picks which is faster.

thats not always the cure. but in the international section of the forums. looks like there was 2 OTAS and one has fixed the wifi issue. so it will come eventually

Thanks for the replies.

Hey all,
I realized that the wireless issues were all where there are at least access points broadcasting the same network. The signal indicator flickers back and forth between solid and weak, and I think the wireless manager is jumping back and forth instead of sticking with the stronger one. I installed one"WiFi Manager" from Play store and the connection is more solid. I haven't rooted my device yet, so this may be the best answer until a patch shows up.
Let me know if it works,

Hello I was having this problem I had to remove my ad stop program and everything starting working normal again adblockplus to be exact but that fixed issues with mms messages and the wifi.

Yes- nothing but problems with wifi dropping and reporting as slow/unstable. Rooted on AT&T MI1. Various AP's, not specific to any one location. Basically renders wifi useless.

I've been noticing WiFi drops also

Yall- this issue has been bugging the hell out of me. Finally tried something I found buried in a few other forums that immediately fixed the spotty connect/disconnect and wifi data stalling errors.
Enter into the service configuration mode by dialing *#0011# and hit the menu key- touch "wifi" and turn off "wifi power saving". Reboot. After having tried everything else I was skeptical but I can confirm (in my case) it worked like a charm!
Hope it helps someone else.

Great info! I just did it and rebooted so I will report back with the results. Thanks!!!

Another possible fix for you guys.. go into wifi in settings..hit menu then click advanced. Inside advanced make sure to uncheck auto network switch. Reboot and voila.

I've been using that method for most of the day, and I've noticed some good results with WiFi. Unsure how it's going to affect battery life yet though lol

auto-network switch
I didn't have to reboot, but disabling the auto network switch did help. I kept getting the 'unstable messages', and I finally had to click the "don't show this again" button and hit 'cancel' so that the OS would stop trying to help my be re-enabling the auto network switch. So, the question is, is this just #LTE2fastprobs, or are there real wireless n/ac issues that make this phone less than desirable?

Wifi wont turn off

I noticed that after disabling/turning off Wifi, it still stays on and consumes battery, although Wifi icon shows switched off in notification and settings section. Restarting phone helps and WiFi finally switches off, however I do not want to restart phone every time when I want to switch off WiFi.
Does anyone have this problem and how ro resolve it?
My phone is in latest version on android 5.1.1 and on previous version I did not have such problems.

A factory reset might help
Sent from my MT27i using XDA mobile app

Thanks, but I would rather keep factory reset as a final option.
Any other suggestions?

Maybe wifi is configured to search for networks even if "turned off". Changing that might help

Sorry for silly question, how to configure WiFi to stop searching for network if it's turned off?
Thanks.

Go to settings - wifi - 3dot menu advanced.
