Data connection keeps turning on?

the Data connection is turning on on a regular basis and I can't find any scheduled tasks set up to access the Internet, but some rogue program is? any ideas any one and/or any way I get find out what is causing this.

I have the same problem.. And I'm a little bit tired!
I wrote on this thread with no answer: http://forum.xda-developers.com/showthread.php?t=529622
I have a flat data plane but I don't like that PDA face things on his own initiative!!

me neither, I'm in charge - not my new toy! Lets hope someone helps us out this time round.

I had the same problem. In my case the 2 apps connecting to the net were Google Maps and Funambol.

Well, I don't use funambol.. And anyway: there are no program in task manamager! So: something is going wrong with manila..

I had the same 'problem', but my brother suggested to turn it off and on again. It did work as far as I could see.
I think it may be google maps causing this, but I'm not sure (and don't really care, since this 'solution' worked).

Any number of added apps can be doing this (Worldmate live is a bad one for example) or any apps still running and not shut down.
Obvious things to check first are:
Do you have automatic email check set?
Have you disabled auto-update in weather and stock quotes?

This drives me crazy too, afaik I have turned off everything yet it keeps turning on... A fix would be highly appreciated!

its the activesync...
turn it off, i mean, delete the settings and you'll be fine. activesync triggers automatic data sync, hence turning on the data connection

I use ActiveSync and don't have this problem. If it was ActiveSync, why would it cause the problem for some and not others ?

Well.. I tested all day.. And I can say that I solved the problem!!!
I think that last time I closed gmaps.. I answered in a bad way to the question about updating Glatitude..
So: Gmaps seemed close but it was updating my position on the net!!!
When i opened gmaps i could see my avatar in the map.. So i understand that it was still online..
So.. I think I've solved!
Anyway we need a "netstat" on pocket pc...
Thank you for your advices.

Glad you worked it out.
I put this in the developers forum a while back. Maybe someone smarter than me will work out a solution to this sort of problem:
http://forum.xda-developers.com/showthread.php?t=530634

As with the poster here. You will have an application that you have inadvertently set to autoupdate. The only thorough solution is to go through every program on your phone and check each setting meticulously. Alternatively. Back up your personal data and hard reset. Then reinstall your apps one by one, testing for an hour after each one. Eventually, you will find the offending app and can work on finding the setting in it to stop it connecting to the net.

Hi all,
the thing is there are dozen possibilities: activesync, alle gps-stuff, all auto-updates. So instead off looking up all these settings, you could also use the nodata.cab - works fine (phone need to be unlocked!)
greetz to all
Kjoere

thanks for all the posts, haven't checked for a while. I have checked everything and noting is set to auto update so very strange and annoying. Will try the nodata.cab - if I can find it?

Thank you! That is very interesting.

It also can be the build-in Facebook app in Contacts in manila. It has feature to automaticly update in 2 hours. At least, I had mine turned on as default.

The only reliable and "ultimate" solution is really Modaco NoData as mentioned above.
On the other hand not taking third party apps in count, basic traffic of HTC device is nothing to be scared of. Updates for weather, stocks and A-GPS are just few bytes in size... Obviously, GMaps, mail autocheck, Messenger etc. are different story, but none of these are started on their own... BTW, ActiveSync has nothing to do with Internet with one exception - Exchange mail sync, if you have any.
What you have to understand, is behaviour of the active data indicator (small G, E or H next to signal strength). If it's there does not mean, that any data are transferred at the moment. It just indicates opened data slot with current brodcasting tower in the cell. It could stay opened for hours after trasfer even just of few bytes. It closes usually only for two reasons - your phone switches to another cell (and has no reason to open data slot again) or the tower is busy and closes inactive slots to gain more capacity.
Except few rare cases in some coutries you're charged only for data transferred, not for time of the connection and therefore it doesn't matter. In Europe from 1st of July (some new EU limit) one Mb shouldn't cost more than 50 cents and with these basic updates you will NEVER reach it in one month...
Obviously, roaming is another story, but in settings of the standard services you can limit updates just for your country.

[Q] Unable to download from Market using 3G?

Update with fix [Thanks jayclapp!]
For anyone with this issue, go into your APN settings and remove anything in the "Proxy" field, right below "APN". Fixed the problem immediately for me + jayclapp!
Original Post Below
----------------------------------------------------------------------------------------------------------------
Hi all,
Having an issue downloading anything from the android market on 3G. 3G works for everything else besides downloading from the market (browsing, email, sync, etc).
When I switch to wifi, I can download from the market perfectly fine.
I've tried a friends SIM with a different carrier, and it DOES work over 3G.
Logcat of the issue happening From what I can tell the error starts around line 50, but I included the full log in case it helps.
I'm not much of a developer so I'm just trying to determine why exactly it's happening, as Android simply spits out a pop-up with the useless message:
[App name here] could not be downloaded due to an error.
I have a friend on the same carrier with a Nexus S and she can download apps from the market fine. Haven't been able to test her SIM in my phone yet though.
I've found some others with a similar issue (although not restricted to only happening over 3G): http://www.google.com/support/forum/p/Android+Market/thread?tid=5a31588b6f655e89&hl=en
None of the solutions there helped though. I've cleared market data, wiped, factory reset, tried different roms, etc.
I'd really appreciate any help.

i'm having the same problem - using a galaxy nexus on tmobile. haven't had the change to try on wifi yet.

Glad I'm not the only one...
By searching pastebin, I've found a few others that pasted their logcats with the same issue, but I can't find wherever they posted it to see if a solution ever happened.
One solution I found was to delete / rename the .android_secure folder on the "SD" card, but I see that folder on my phone. I know dotfiles are hidden by default but I'm showing hidden files and I don't even see .android_secure from adb shell.
I'm on Mobilicity in Canada, which also uses AWS bands, not sure if that has anything to do with it.

I don't like bumping, but I still have this issue and was hoping someone could help out.
Sucks only being able to download apps over wifi.

I saw Josh Topolsky from The Verge has been complaining about this issue on twitter the last couple days.
www.twitter.com/joshuatopolsky

I've tried everything to fix it, tried different roms, kernels, wiping, factory reset, different SIM cards, nothing will fix it.
The 403 error indicates that it's Google's servers that are forbidding the connection...but I see no reason why they would, and it's not like I can change the IP address of what my phone is being assigned by the 3G towers.

Everthing was fine on stock untill i flashed revolution hd 1.3.1... I had the same problem with market but for some reason i enabled wifi and started downloading stuff from the market...then i turned it off and magic it worked thru att 3g...
I hope this temp solution might help you guys out or maybe it just worked for me

Ditto
I'm facing the same issue with a Galaxy Nexus (bought from Virgin) on Mobilicity in Toronto: market works on wifi, but not on 3g.

I'm having this problem too. With Orange in Spain.
But is not a constant problem. Sometimes works fine, and another ones not. When the error comes out I try again several times untill it works. If doesn't I whait to have Wifi.
But as I said it isn't always. But some type of bug is.

I got the Galaxy Nexus yesterday from Virgin Mobile and using it with my Telus SIM and Android Market downloads dont work using the mobile network but switch to wifi I can download from Market. I've tried everything you mentioned as well and still no luck.

I have noticed some delays in downloading but I am pretty sure it is becasue of the "little" 10 Billion Apps promotion thats causing the issues.. the market must be seeing a lot more traffic than it can cope with.. servers must be over loaded!
Try market at off peak times (worked for me)!
This theory syncs quite well with the 10 Billion Apps promotion.. just a thought!

Unfortunately that isn't the reason. It's definitely something more serious / buggy than simply too much traffic. It's been going on for almost 2 weeks now, well before that promotion even started.
Anyone feel like pulling a logcat and seeing if it matches up with mine? I'd suspect it does (403 Forbidden errors).
It basically boils down to Google's servers rejecting the connection for one reason or another. 403 error = The server is connectable, but knowingly refused the connection. It's something on Google's end, but I don't understand why certain devices are being rejected while others aren't.

Went to apn settings and removed the proxy and now i can download from market over celluar

Just wanted to confirm your fix worked for me jayclapp!
Updating the OP with the fix, in case anyone stumbles across the same issue.

Bumping up the thread but i believe it's for a good reason.
I had the same problem with I9100 after upgrading to ICS from GB. Talked to Google play support, their solutions weren't helpful (erasing cache and stuff) and they said it's a carrier problem. I used another SIM from the same carrier and it still wasn't working....
So.... Stumbled on this thread, erased the proxy and now it's working!!!
So, i'm bumping this thread so it will perhaps show up in google in a higher search position and to say thanks to the OP (besides the thanks button)

Mobile Network Traffic despite WLAN connected

Hi,
when my HOX is lying near by PC Speakers, i can hear Internet Traffic over EDGE/UMTS excatly all 3 Minutes. (I hope u can understand what i mean)
I´m wondering about that bescause WIFI is active and connected, and i never had this with my DHD.
Due to optimizing Battery life, i disable mobile Network manually when i´m at home and have WIFI connected.
I use ARHD 9.1.0 with stock Kernel and EQS + APM + %Batterycircle + Autobrighness by jotha.
Baseband: 2.1204.135.20
Build; 2.17.401.2 CL89015
Any Ideas whats generating this traffic and why the HOX don´t use WIFI for that?

its normal gsm traffic. like if somebody sent you an sms, you would hear that sound. not sure why it didn't do it with dhd and now does with hox, but either way, shielded speakers are there to solve that problem. as for adapting your current speakers to shield them, not sure if its possible or not though.

Thanks for your Answer, but i don´t hear that Traffic if mobile Network is disabled, so i thinkt it can´t be "normal GSM Traffic".

oh i see what you mean..
might be network location services?
settings>location>google's location service.
i know the location services use wifi as well, but it might use mobile network in conjuction even if connected to wifi.. try disable that and see if it continues.

try download osmonitor, might be other apps more specific that can help, but osmonitor should do the trick i hope.
set your screen not to turn off, just for ease..
goto the connections tab, process tab will also be useful and watch it until the noise happens. you're looking for either a process, that jumps to the top of the list when the sound happens (spike in cpu usage), and then does it every time the sound happens, or a connection, that ISN'T your local or external wifi ip address, but also has similar behaviour, ie the connection is created when the sound occurs, and is then gone a minute later.. (the connection should show an app name)
if you find an app that looks like it could be causing it, then try to uninstall it temporarily to see if it fixes the issue. if it does fix the problem, the next step would be to contact the developer of that app to request a fix for it. it could however be a system process causing the problem.
failing the above, you could try the same sort of diagnostics, but with logcat instead. i don't actually know how to initiate logcat, i'm sure a google will tell you how though.

Thanks again! (i´ll hit the Button )
Okay, got that app installed.
Unfortunately the Sound DOES NOT appear all 3 Minutes when the Display is on.
When it starts and i unlock my screen i cant see any new entries in the Connectionstab.
Processes the same, but "Android System" shortly came on Top. (maybe the Display Unlock is the Reason for that?)
BTW: Why i got 2 permanent open Connections?
1. Google Bookmark-Sync (Whois -> Google)
2. Downloadmanager (Whois -> "The New York Internet Company")
Not idea what that could be.

you should be able to set the display to never turn off in settings>display and gestures
i don't think it'll be very easy if even possible to find it if the screens off (the spike would only be there for a second or 2, by the time it's unlocked etc it will have disappeared)
the other connections, first one is probably the google account sync, and not sure about download manager, maybe something got stuck, you could try clearing data for the download app, but to be honest i doubt that they're any problem anyway so probably nothing to worry about
edit: the download manager bit judging by the whois could be an app relating to that? do you have anything similarly named installed?

This is crazy - when the screen is on, the sound isnt audible. It only happens when the screen is off.
In the Connections Tab is only one Connection without my WiFi-IP, and whois shows me its a DNS Server from my Carrier (vodafone).
In the Process Tab i can see that "System" comes up on Top for ca 2 seconds, further no action.
The 2 Connections which stays established:
Clearing the Donwloadmanager Data was a Success... Thanx again.
The Connection to Google from "Google Bookmark-Sync" is still there. Gmail Sync is deactivated in accounts.
I think i´ll give it up and live with it

[Q] "Sign in to network" notification

Hello,
A few days ago I started receiving a notification saying "Sign in to network" and below that the name of my carrier (see the screenshot). When I click on the notification, the browser opens up but does not load any page and just stays blank. At that time the notification disappears but then appears again after a while.
Has anyone seen this and do you know why it may be appearing? I am fully stock on 4.2 and unrooted.
Thanks!

Does nobody know?

Hi,
Same problem here (with Mtel network operator),
After updating to 4.2.1 the problem still persists. After I click on the notification it asks me to open in a browser and then opens this address for a second 173.194.70.101/generate_204 , and turns into blank page.
I think that when I walk away from one network cell to a another it asks me to sign into the new cell, but I am not really sure..
I`ll keep posting if I find the solution..

Not sure if there is any difference for GSM variants of Gnex, but have you tried updating your PRL & Profile?
(Settings>About Phone>MTel? system updates)
Sometimes after a flash/upgrade until I update my Sprint profile, service seems spottier. Only other thing I can think is that your phone somehow is no longer provisioned with your carrier, shouldn't be the case (I think) when dealing with GSM carriers since your SIM what provisions the phone, but maybe poke around settings to see if there is some sort of self-provisioning option, or call M-tel.

Check your APNs. You might need new/corrected APN settings or something. That usually shows up when you're on a network (usually WiFi) that needs a user/password or accept a disclaimer to get through to the internet.
However on a mobile network the APN should serve as the connection settings and the SIM serves as authentication to the network. Normally you wouldn't be able to connect to mobile internet. Does MMS work?

Hey, guys, thanks for your input. Actually, since yesterday I stopped receiving this notification all of a sudden. I have not done anything in the mean time, so I guess it was something on the carrier's end that got resolved or something.

I'm also facing the same problem. I'm on Vodafone Portugal and occasionally I'm with full network signal but I don't have internet. When I check the notification bar I have that same message and if I click it, it opens the same "empty" web page.

Hi there. Since this issue disappeared for me without any action on my end, I am assuming that it is related to something on the carrier's end. It may be worth contacting your carrier's support?

im facing into the same issue too.. but still not solved till now..
its not apn related problems for me..

Have the same problem Here
Hey guys, i just have the same problem here.
It has been 10days till now
currently using galaxy s4, android 4.2.2, from Indonesia (carrier's : XL Axiata)
Does anyone know how to fix this problem ??
It will very helpful to me, cause i'm very annoyed of this notification
this notification (Sign into Network) pop up nearly 10 times a day.
I have several times contacted the carrier (XL) and the samsung centre too, but both didn't know what is the problem.
Thank you.

Hi there. By trial and error i found out that this icon starts appearing when the carrier throttles your internet speed. For example, I have unlimited internet traffic but when I reach 512 MB of traffic, the internet speed is lowered to 128 kbps. This is when the icon starts appearing for me. I also found out that if you dismiss it, it will appear again if you change connections (e.g. go from wifi to mobile). I find this behaviour annoying but I found no way to prevent it, as it seems to be something on the carrier's side.

I have the same problem only on my android phone (4.2.2) Samsung Galaxy S3 when I am at my home WIFI..
Could it be a virus. only diffference is the IP.. my browser tries to load this: 173.194.35.99/generate_204
i've blocked this IP. I can't even access play store now! rest all things work

i dnt think its caused by virus. Try check ur apn setting. Or reformat ur phone.

When you connect a mobile device with Google Play via WiFi, I have found that I must allow ssl traffic via port 5228. This connection I think is an authorization service deployed by Google. If you trust it or not, when you block outbound port 5228 (or if you block Googles' ip's) you will see the "sign into network" This is because Google Play assumes (poorly) you are connected to a WiFi network which requires a captive portal login (ie Hotel WiFi sign-in page). I am no dev but I believe the "generate_204" thing just forces the mobile browser to open a new tab so the login page will appear. It's not spooky just annoying.
Why did Google choose to deploy ssl over port 5228 and not the standard 443? Not sure, but it might lead to your Firewall's security policy blocking it as it did for mine.

I started getting the same notification on my nexus 5 recently. I had reached my data fair usage allowance and so it started appearing. I noticed that in the data usage setting the warning bar was set to my fair usage limit so I just raised the bar and hey presto no more warnings. Based on this I reckon when your data usage cycle resets each month you'll see the warning disappear until you hit your limit again.
Just done a quick test by dropping the data usage bar back to where it originally was, turned off WiFi and started browsing the web. The warning appeared again.

I have had this issue ever since I got this current phone (not a Samsung, but hear me out). From what I can tell, it is because it can not contact someone (probably Google) via cellular network. I also get this when on a WiFi connection with no internet (or very, very slow), further supporting this.
I am in an interesting situation. My carrier only has 1 APN for both MMS and data combined. However, I only get MMS with my plan, not full data. Therefore, I need to keep data enabled in Android to use MMS. Because of this I get this notification ALL THE TIME.
I'm going to try to get a logcat when it happens and see if I can find the exact service and maybe kill it. I'll update if I figure it out.

I have the same problem.It make notification at the time u linked to mobile data too, and i can't suffer it any more.So i have searched all internet and have no progress.But i found the way to block its notifications rather than voiding generation.
It's a notification generated from "Android System" and seems like a network-check function. So the problem have the mobile carrier's part(I'm in china, you know). And u can't block all notifications of "Android System" using tools like LBE or Gravitybox or anyothers cause it is useful all the time.
This Xposed Mod can help us: NotifyClean, it is the only tool to block several notifications u want of one app.
Use it in ur rooted system with xposed framework,and open it from xposed. It can log all notifications and u can tick the "Sign in to network"s in "Android System".

Returned home from short trip, Wifi connects but does not function

As the title says, I didn't change anything about the phone's configuration when I was out, didn't download any new apps or change any settings that would interfere like this. No one else has changed my home network in my absence.
Nevertheless, most of my apps, such as Instagram, the Play Store, Twitter, Wikipedia, Chrome; almost all their requests time out. There seem to be short windows where data will load, and Instagram appears to load comments and post metadata, but no images. It's basically unusable. Occasionally an exclamation mark will pop up over my Wifi symbol in the notification center. Strangely, I can still reach my Steam and Battle.net authenticators, but the moment I try loading the Steam app, nothing comes up. It's like the device can only handle plaintext over Wifi.
All of the apps work fine over cellular data.
Also, there is a toast that appears whenever I restart my phone that says "Power On" that I've never noticed before. I was rooted using Xposed, the only modules I used were Snapprefs, Xinsta, Physical Button Music Control, and Greenify Experimental Features, all of which I uninstalled. The toast still appears with the latter two disabled. Only other rooted apps I had besides Xposed were Nova Launcher, Greenify, Busybox, and Root Checker Basic, all of which have been removed but Nova.
I am running 6.0.1 with the latest update.
Any ideas? I am still within 15 day warranty so I could theoretically return the phone (which I was contemplating doing anyhow since 10gb of functional storage is a bit too small for me), but would rather not have my hand forced, and eat into my cell data plan.
So far I have tried forgetting the network, wiping cache/dalvik with TWRP, removing the Google VPN, resetting all network settings, and a couple things I can't remember offhand now. Any suggestions will be appreciated.

First, if you want to return your device because the 16gb model doesn't have enough space, go ahead.
If it is mostly because of this WiFi issue, I wouldn't return the device, it is almost certainly the case this is some configuration issue (possibly in concert with some Android bug) which can be resolved.
Is it possible when you came home the device connected to a neighbor's AP and thus you couldn't use data, but it wasn't immediately obvious, so you ended up forgetting your own network and reentering the config, but the key was off by a little, and from that point on, it was just assumed the wifi config was correct?
When you say Google VPN, are you using WiFi Assistant and Project Fi? Have you tried disabling auto-connect fir the WiFi Assistant?
Have you tried using the old Lollipop DHCP client (perhaps your IP address got used by another device and the new Android client doesn't handle that well?) Just grasping at straws.
Have you tried turning on Bluetooth while WiFi is on? Perhaps there is a bug with them working independently of each other in certain situations.

I am 100% positive I am on my own home network and that I used the correct key. I'm not sure what you mean with regards to the rest of the 'config', I have always used the standard wifi configuration, just typed in my key and had it work.

When you say Google VPN, are you using WiFi Assistant and Project Fi? Have you tried disabling auto-connect fir the WiFi Assistant?

I actually forget what it was called, it was under Settings>Wireless&Networks>More>VPN. There was one entry there with an icon. I forget the name of it, but the icon looked like a stock Google icon and I think it had google in the name. I am on Project Fi, not using any wifi assistant (at least not in Advanced Wi-Fi Settings), but when I tried to toggle that option on just now, something called "VpnDialogs" crashed, so I assume that VPN entry was that. But again, the assistant wasn't on.

Have you tried using the old Lollipop DHCP client (perhaps your IP address got used by another device and the new Android client doesn't handle that well?) Just grasping at straws.

I did, when I first googled this was one of the things I found, sadly it did not help.

Have you tried turning on Bluetooth while WiFi is on? Perhaps there is a bug with them working independently of each other in certain situations.

I don't use Bluetooth, and trying to toggle it off/on from the control center just gives me a repeated "unfortunately, Bluetooth Share has stopped" error message.
I have decided to get the 32GB 5X since I do want more storage, but since I would like to be able to root my phone again and use Xposed, I would still like to hear any other ideas you have for troubleshooting this problem in case it reoccurs.
I reflashed the latest update to see if that would fix it, no dice. When I send the 16GB model back I have to factory reset it anyway, so I suppose I'll know if that does it.
What puzzles me is why I can load text from instagram posts that have been posted while I've been having this problem, but not images. Makes me think that maybe my connection is being super throttled somehow rather than non-functional, but my PC's speeds are normal. Perhaps some internal part is damaged? I do have a case and it hasn't taken any serious tumbles, but it has had one or two small falls from maybe 2 feet high.

It is easy to test if you have some network connection vs none.
In terminal or adb shell
ifconfig wlan0
ping www.google.com
1st command will tell you (among other things) if your wlan picked up an IP address.
2nd command will test whether you can send ping packets over your connection.
I'm sure there are millions of ways of doing the above, I just gave you one example.

Strangely, the solution seems to have come from factory resetting my router. I ruled this out initially because my other old phones were working fine on wifi, my phone is now getting WiFi again.
Now to figure out what the hell this "Power On" toast is about...

I've encountered something similar where the router runs out of NVRAM space because it has recorded too many DHCP clients, it won't hand out new IP addresses, but if you are existing or already have one, it is fine.
