[Q] [AT&T] Losing data connection when leaving wi-fi network - Galaxy S III Q&A, (US Carriers)

I don't believe I was having this problem at first, but now when I leave a wi-fi connection at home or at work, and I try to use the data connection it doesn't work. The phone is not switching to the cell towers for some reason. I have to disable data, and sometimes wi-fi, and then re-enable data on the phone to get a connection. Or reboot
This is stock btw. Anyone else have this problem? AT&T support was no help
Edit> Just left my work network to test it out and it switched this time, so it doesn't happen every time. Which makes it more frustrating.

Mine was working just fine a couple hours ago, now I get absolutely no data. This is very frustrating.

WiFi issue on my Hero...

Hello everybody!
Someone of you has noticed a poor WiFi reception on Hero?
I'm experiencing a poor WiFi reception in my house when Hero is connect to internet thru an access point.
What happen is that after WiFi connection has been established the phone tends to loose it and restart connection thru GSM/3G link.
That happen also if phone stay in the same place without moving around and also when phone is close to access point location.
Any idea about way to solve the problem?
Regards.

Just an upgrade on issue...
If I turn off data connection thru GSM/3G and switch on WiFi seem that WiFi connection is stable so maybe issue come when both data connection are enabled...
Anyway is annoying shout down each time data connection on GSM/3D and power on WiFi!
Regards.
i believe wifi goes idle when not in use. so it connect to 3g or edge. However there is an app if not various in the market already to help keep wifi always on..
Do a search for wifi and see for yourself.

Thanks for suggestion!
At now I've solved turning off GSM/3G data connection when I'm at home anyway I guess that WiFi reception sometimes go away due to issue of the phone or maybe as way to save battery...
when that happen phone stay unconnected so I guess that should be better if I will check for apps that keep WiFi connection always working!

when the device goes into standby, the wifi is turned off to save battery poweer, and it will go back to 3G.
go into the wifi settings, press menu and select advanced.
select the timeout options
set to never and it will not turn off when in standby.
problem solved and you shouldn't have to turn off Mobile data, although with the settings widget on your homescreen turning mobile data off off each time is hardly going to ruin your life. in fact i tend to do this anyway, just cos i have spent too many years with windows mobile....
Here's an annoying bug I've found tho - on TMob UK
If I send an MMS from home, wifi on, it sits there, and doesn't send the message. Until I turn off wifi and 3G kicks in again.
Now I know for a fact that on my Magic, it was able to turn on 3g/HSPDA to send the message all by itself. Might have a look in thodse advanced settings tho to see if there is something I can do.. Not a biggie, just a bit of an annoyance.

I too, have been doing a search on Forums all over Google looking for a resolution to this.
I have noticed if Wi-Fi is enabled I am unable to send or receive MMS messages.
It is an annoyance having to turn Wi-Fi off each time also I am never to know if someone has tried to send a message in the first place.

[Q] While connected through Wifi, Opera does not connect

Apologies if this has been resolved eslwhere, but I did a thorough search and I could not find the solution in similar questions asked for the exact problem I am having.
I have an HTC HD2, basic Rom 1.66.405.2 (76641)with Max Manilla, Radio version 2.06.51.07.
I have previously used Opera 9 and Opera 10 to surf the internet along with Skyfire with no problems when using the 3G connection or when connected to my home or work WiFi, until a few weeks ago. When connected through WiFi, having changed nothing on the network routers or my phone, I just cannot get to pages. The same is with the facebook app and any updates via weather or stocks/shares.
It seems that as soon as WiFi is connected there is no data connection.
I have checked data connection and it is OK, I have also tried the slider the best as suggested on another forum, even re-installing Opera 10, to no avail.
I am considering switching to Energy Max Sense at the moment but hesitating as I can't bear going through another hard reset and re-installing everything, but this issue might just force me down that route.
Any thoughts before being forced down this route?
Been through lots of different settings and basically it appears that once wifi is connected I lose all data connecions, nothing then connects.....Please help?
Did you ever get this fixed, because I am now having the same problem.
I used to get internet data connection via wifi by first turning off data connection in comm manager, then turning on wifi. I must have screwed something up, because now I cannot get any data traffic via wifi. I can't even get data from my cell network whilst wifi is on, I have to turn it off to get my GPRS connection back. Bit frustrating, been through connection setup and delete/setup network many times to no avail. What have I done... harrumph!

Why Disconnect data connection before activating WiFi?
I leave it on, still it will get data through WiFi is available.
If you disconnect data connection, you will not get data through data connection. (while you have WiFi activated, as you switch it off)
Have you tried using both at same time? Perhaps disconnecting data connection does a "trick" so you can not get data through WiFi too and you are now experiencing expected behaviour. (And that it did before was the wrong situation.)
i tried lots of stuff, soft resetting each time, I then did a full sync and backup to my home PC (work PC has firewall and stopps internet connection).
After that I did a cache cleaner and emptied a lot of trash, it did appear to be running slow. Did another soft reset and voila in the morning it was all working.
I played around with settings, double checked everything and to the best of my knowledge nothing had changed to cause this fault, so no idea if it was a problem with synching between the two PC's, work and home, or whether the cache cleaner did the bizness. Never had the problem repeat again since.
Have you tried getting settings from your provider again maybe something got wiped by accident.

[Q] Phone looses data connection when on a call

I'm having this issue almost all the time.
After some minutes on a call (after 5 or more minutes) the phone looses data connection (either HSPDA or 3G or GSM).
As soon as I hung up the data connection restores again.
It doesn't matter if using Bluetooth or speaker.
Mostly it happens while I am driving and I have GPS turned on as well...
It did this since day 1. Have tested ALL modems so far and all ROMs (custom or stock). Nothing would fix it.
It's not that it switched from 3G to 2G, it is just loosing any kind of data connection/connectivity.
Is this an operator issue? Vodafone Romania
Any idea?
Thanks.
Hi
The same "problem" here Every time I have a call, the data connection is lost. As soon as I hang up, the data connectin restores again.
I had this issue also with other phones. Maybe it is a operator issue. To safe bandwide??
It doesn't matter if I have 2G/3G/GPS/WiFi on.

[Q] Wifi and data on at the same time, limited internet.

Rooted stock ROM Verizon I605 running 4.1.2.
I was in Korea for the past 6 months and just got back the other day. Before I left, I never had any problems, but since returning, my wifi and data are on at the same time, and it's causing me problems. Here's what's going on:
If I just have mobile data on, everything works as it should. If I turn on Wifi, it will connect, but the data connection will also remain, and my internet speeds will become spotty. If I turn on mobile data and just try to use wifi, the Wifi icon appears (with the orange/green arrows indicating activity), but apps don't connect. Facebook automatically tells me "No Internet connection," Opera won't load pages, Google Talk can't sign in, etc. If I turn mobile data back on, things work again, albeit slowly.
The strange thing is if I turn on Airplane Mode and then turn it off, leaving data off, my wifi will work 100% normally. If I try to turn on mobile data again, I get the same issue.
While I was away, I replaced the SIM card so I could use my phone over there. I messed with some APN stuff thinking I would be able to get data on my phone in Korea, but that didn't work out so I returned my APN settings to default. I have a feeling that's the source of my problems, but I have no idea how to fix it. I tried restoring my APN settings to default through the settings, but that didn't fix it either.
Any help at all would be appreciated!
If it helps I have been seeing the same thing. I'm on CleanRom 3.5 (Verizon Rom base) and PB&J kernel. It seems to be hunting between them even when in strong wifi signal.
Interestingly enough it's not doing it right now.
I'll keep a closer eye on it now.
Sent from my SCH-I605 using xda premium
In my case, it's a constant problem (unless I manually go into airplane mode, like explained). It doesn't work sometimes and not work other times.
I'm trying to use wifi at home, so signal strength isn't an issue either.

Data (Wi-Fi AND Mobile data) issues

Ever since I received my OPX I had little problems with my data, independently of using Wi-Fi or mobile internet (2g/3g).
It started with the fact that in the installation of the phone it couldn't connect to verify it's connection, although wifi was connected correctly.
I started it without the connection it wanted and factory resetted it and then I got the same problem, but after a few minutes it worked correctly and I could install my phone without any problems.
Now when I work with my phone (Whatsapp, 9gag, webrowsing, video streaming) it sometimes stops with loading, like it has lost its connection, but both Wi-Fi and mobile internet are connected.
This is very frustrating when watching video, since it just won't buffer anymore and I have to wait for like 1 minute before it continues and reloading the page helps most of the times, because I then force to get data.
Sometimes when WhatsApp isn't loading/ keeping it's connection I just start a SpeedTest to ensure it has an open connection. This works most of the times.
Also WhatsApp Web keeps losing its connection while the screen is on.
I hope you guys have some ideas on this subject.
I have a similar issue. In my case the device seems to have problems with certain WiFi-Networks (at university to be precise). The connection with the WiFi is still there, but there's no actual connection to the internet sometimes. That's why your mobile data doesn't activate - there are no connection issues on mobile data for me.
The cause for this is probably the lack of a 5GHz WiFi antenna. I don't know why, but my OPX cannot handle the 2.4GHz WiFi at university (at home it works fine!).
So to test this out, you should try different WiFi-Networks. If the network is 2.4GHz only, it should be working.
The WiFi thing while setting up the phone is a known OxygenOS bug and can be worked around.
