hi, my mobile internet stopped working a few days ago, it wasnt after an update or anything, the only thing i can think of is i enabled installing to sd card and put it back to normal.
my phone was and is unrooted desire stock latest firmware. im on O2 postpay.
ive attempted to fix it by checking all the apn settings, restarting my phone, turning my phone off for ten minutes, factory reset, but still it seems i have no internet even with the right settings..
i turn wifi off, mobile internet is switched on, i do not get any mobile internet icon up top, and of course nothing.
any help would be much appreciated. thanks in advance.

I have faced similar issue as you describe here. I had internet until I installed an application on my HTC Desire (Froyo 2.2). It was some application which would let me access my HTC files through a web interface from my LAN PC. After I uninstalled the app I did not have access to the internet though it was connecting to WiFi.
Issue was solved when I did a factory reset of the phone, I lost all my apps and contacts, but after this internet was working again on my phone. Now I'm thinking that I better had to check what was the VPN parameters set as I believe that program could set some values there without reverting back after uninstalling it.
Hope this helps.
hi thanks for the reply but as i said, i have done a factory reset and its still not working..
Im on O2 uk and my data stopped working today, my apn name had the word void at the end???? i reset to defaults and its been ok since.
i guess O2 had some problems
Mine never said void but ive reset it to default many times, no change

I dont know how to, i did blow on it and rub it a bit.

Just a though
Do you have any VPN declared in the settings?
(Settings/Wireless & networks/VPN Settings)
No.
But its sorted now. I got the new sim but it didnt work so i went back and they said when they switched the sim they accidentally removed the free internet bolt on.
I think they may have bullshitted me somewhere but it works now anyway.

OK, I have been dealing with this since I bought my GSII and cannot find any information about it.
Firstly I want to say that I am completely stock and unrooted.
My phone does not like to keep a stable data connection. About 50% of the time, when I try to do anything that requires a data connection (facebook, browser, gmail, etc.) the 2 arrows under the 2g/3g/4g icon will stick being grey and my phone just sits there "loading". I tried a factory reset, didn't install any apps, and also got a new sim card and the issue remains. It happens everywhere so it is not just a bad network connection.
I decided to post the question here because yesterday I was playing with my brother's GSII, and his did the same thing.. So it made me think that maybe it wasn't just me. Has anyone else experienced this? Or does anyone know what might be the cause?
Edit: I set my phone to use 2g only, and the problem vanished.. So it doesn't like to connect to 3g/4g.

Try going to your mobile network connection settings, choose access point names, hit your menu button and click "restore defaults".. It may fix it, I had data issues and it did the job. Hope it works for you!

Do what the gut above me said. Also call Tmobile and tell them, they will refresh your data connection on their end. That will clear up three problems your having.
But if it's also happening to your brothers phone, it's a network error. Call Tmobile.

I restored the apn settings and had Tmobile refresh my data connection, and it still happens. I noticed today that it's not just data, I'm also unable to call or text when it happens.. Tmobile just said everything tested normal so there is nothing they can do.. And I really don't think it's the phone so I don't want to exchange for a refurbished unless I have to.

Its happened to me before. For about a week, the data connection just dropped. It would come back for a bit and later vanish. I called t-mobile and they guided me through routine steps (i.e. taking the battery out, rebooting, resetting) but nothing seemed to work. They really couldn't figure it out and later told me to replace the SIM. I can't remember if they shipped me one or had to go to the store but either way that relieved the problem. This was on an HTC HD2.
That might not be the case with you though. At one point in time all the phones under my name lost data connectivity just as you explain. This really had no solution but to wait it out.

you mentioned your brother's is doing the same thing, its probably not the phone, but rather the cell tower your connected to is fuggin up. Try going 5 miles from where you currently are and see if its still happening.

Just in case it's not a cell tower or network problem . . . My SGS2, purchased in October, had the same symptoms as the OP. After trying everything the OP did, and more, I came to the conclusion that the firmware on the phone was corrupt. I used Odin to flash the factory stock ROM & Kernel images (2.3.5 at the time). There was a definite improvement in the faltering/hesitant/fail connectivity problem at that point, but it was still very subpar. So I then also flashed, again using Odin, the baseband ("modem") image - I did it twice for good measure. The problem was finally immediately solved at that point and I had very prompt loading of webpages, etc. Still working fine months later (and even better with a custom ROM). See the thread entitled "[Q]Is there a "true" factory restore for T-Mobile Galaxy S II?" for help about the seemingly same symptoms/problem you (and your brother) are experiencing. If your underlying problem is in fact the same as mine (and the poster of the thread I cited) then it's apparently either a bad factory flash or a post-factory corruption occurrence that is causing your problem . . . the coincidence of your brother also having the same problem aside. Good luck!

Got a Note 3 right after they came out.
Had an issue with the first one, not the least of which was the pervasive WiFi disconnect issue many of us have been seeing; in my case also had extreme battery drop all of a sudden - like 45% in an hour - not abnormal use.. So, swapped it about 20 days ago for another one.
Seeing the same WiFi connectivity issue I saw with the first one and then all of a sudden got a pop up :
"Prevention Information"
An application has been forced to stop for an unauthorized attempt to access system in your device. It may be safe to delete an application obtained from an unauthorized route. Check Now? (with a Do not show for 30 days check box; Cancel or Ok buttons)
If you click cancel pop up comes back after about 10 mins more or less; if you click Ok you get brought to a list of what you have downloaded to weed through whatever you've installed.
Full disclosure: This device is out of the box, not rooted; stock Rom. Only none play store apps installed were Adobe Flash and Amazon App store. I use WiFi extensively for WiFi calling at my office, since there isn't a carrier on the planet can get me a decent signal. I live and die behind WiFi calling it's why I went T-Mobile to start with.
* So I proceed to scan hell out of this, using Lookout, Sophos and MalwareBytes can't find anything..
* Ok so I uninstall everything I've been experimenting with thinking maybe the mix is a problem. Doesn't solve it
* So then I do a software Backup and restore - and go to put back the one app I need the most for my Hosted Exchange connectivity to work the best for my needs adding them back one at a time to see what's causing this . Of course I turn WiFi back on to connect to my network and signing into my Google Account Google Play takes off to restore all my stuff and do all updates for anything stock on the phone. (Phone Vendors WAKE UP; Stop making the default Google Play behavior Up Date Automatically when on WiFi, let the user decide before taking off to do what you think is best) And - The pop up is back just as I get the 1 app I need on the phone. (email support for the app saying it's them - MANY APOLOGIES to Nitro Desk, it's not them.
* Very long story and many soft and hard resets, to try control the behavior, later; including running 2 miles up the road to control Google Play auto update on WiFi, but, only be on the T-Mobile network for the initial startup....
With nothing but a minimal start-up and No Apps installed other than what Google Play demanded to be able to work at all out of the box when signing in; once I got the phone back to the office and started WiFi for my network - Blammo ! the pop up is back.
This "error" or warning message is from the base Android/Samsung/T-Mobile deployment configuration for a Note 3 when starting WiFi at all.
So, I happen to be near the T-Mobile store I bought this at and go in to tell them about this and the guys there running a Note 3 say they all get the same issue.
My conclusion is that this is a miss-configuration of software and/or permissions at the core OS level when starting WiFi; likely contributing or the primary cause of WiFi connectivity issues on this device; as reported in this and other forums.
I have screenies of this condition and would love to pass this to T-Mobile and Samsung engineering, but, unlikely I can get at them to do so; hopefully they are already aware of this and working on a fix.
The other interesting thing I noticed is that when doing a hard reset: during the start of recovery mode I get an "error" then no command message under the little droid as it settles down to the menu.
Also at the end of the recovery mode process for wipe data/factory reset I get an "error" message in red as well.
Again, seems to me there's a serious flaw in their Core programming setting up proper permissions for the base WiFi stack to start without triggering a security violation.
It doesn't matter if you connect to an AP or not. Just starting WiFi the pop up will come up in 60 - 90 seconds.
This is consistently reproducible.
T-Mobile is sending me another phone; but, I believe it will behave the same way - hope not, we'll see.

You really need to SEARCH before posting. There are many threads about Prevention Information and it has nothing to do with WiFi.

That may be, but, in this case it is 100% reproducible under these conditions and happens if WiFi is turned on at all before any updates and before any additional apps are installed, other than the ones the Play store insists on bringing in to work properly once initially signing in, happens to me in this very limited and controlled startup of the device and only when starting WiFi and no other time in that controlled condition; before any updates or Play Store apps are installed.
It also happens after they are; so it seemed,to me at least, to have value because of the controlled diagnostic startup; since the condition is 100% reproducible using these steps and under these limited initial startup conditions, at least on the device I have in my hands at the moment.
A replacement should be here sometime today and will attempt to reproduce it on the replacement; T-Mobile tech support seems to think it will behave the same way as well; FWIW to anyone.
Thanks so much for the input and advice; duly noted.
Best regards,

Knock yourself out....
You might try doing a simple Google Search for samsung "Prevention Information" and see just how many threads there are about this issue. It is not just the Note 3 but a number of other Samsung devices as well.
Actually it has everything to do with wifi. Knox is thinking wifi is trying to collect information from your device as if it is a type of virus. Samsung is fully aware of the issue & there is an update coming based around that specific issue.

+1 Thank you slpn...
I'm glad to hear there's some fix in the works. Do you have a link handy for that? It's clear that the shipped Knox/SEAndroid configuration shipped on this device (and perhaps other Samsung models) really wasn't tuned very well before release.
OP, if you want to know more about this read some of the other threads here about Knox - the Everything Knox thread in this forum is pretty good IIRC, and the Samsung Knox whitepaper is an interesting read too (here). Basically, Samsung rolled their own solution for bring-your-own-device enterprise users, which is based in part on the SELinux extensions to Android (SEAndroid) along with some lower-level supervisory logic that's probably somewhere in the boot loader / modem / etc. [speculation] and some degree of hardware support such as the "knox warranty void" flag.
Unfortunately they developed this alongside/outside the reference implementation of SEAndroid, wrote their own APIs for interaction, etc. and don't seem to have done it terribly well. I'm tempted to ask that Samsung provide some way to actually control it, or provide a signed development FW that won't trip the hardware flag, as it really is an intrusion for non-enterprise customers. >.<

Actually I've gotten the notification without wifi although it usually happens when I do turn it on.
Totally agree though that a simple search would have saved a HELLS of a lot of trouble. Smh
Yes it's a bug but it's not really that big of an issue. I can almost guarantee it will be fixed soon with some kind of minor update.
Well I have two other issues besides the "prevention information" for some reason my note 3 keeps giving me a unstable wifi connection when the connection to the wifi is good for example on my note 2 is perfect mo issues no lags on the note 3 however I get that unstable wifi connection, and for my second issue I get a damn google+ app crash every time im on the phone or any app . This note 3 has become a nightmare with bugs . I was wondering if anyone else has the same issues besides the prevention information ???

I think I had the unstable connection problem a long time ago. I may have made my phone "forget" my wifi network and obviously have connected to it since and have not have that problem. So it's possible simply "forgetting" the network, scanning, and then connecting to it again could fix it?
How often do you use Google+? Is it possible that if you hardly use it you could just sign out of the app and then it won't search for your location so much? I see the new G+ update says something about refreshing friends location more often or something, could be tied in to that?
I dont use google+ at all. It updated on its own and it started crashing since. I just turnt off all my auto updates and I uninstalled the last google+ update lets see if that does the trick .

You can take it how you'd like cause i know how some are when they hear about an update, not saying your one of these people who flame on the other person who try to provide helpful info about an update, but that is also being included in the update i spoke of a few posts above.
What is going on is your phone is scanning your signal & even if you have a full WiFi signal, instead of just leaving you on WiFi like you'd like, it boots you off of WiFi saying internet is unstable if it considers the data connection as being a stronger signal. its a real ignorant move and overlook they made when adding this function. if on WiFi they should let you choose if you want to change connections,or better yet not even bother you to choose between the 2 cause it will interfere with what your doing at that time while you have to choose which connection you want to use. But this is involved with the update we are getting. Verizon already got an update that had to do with WiFi issues with this being one of the issues it fixed.
If you haven't been told yet though, go in to WiFi advanced settings in your WiFi connections menu, and turn off auto connect & always scanning, then dial *#0011#, click your bottom left button on the white part of the phone you'd usually use to bring up the settings menu option, choose WiFi, turn off WiFi power save mode, WiFi power save mode being tuned off cause your battery to drain about 25% faster but this is proven to work. But after a day or 2 always leave WiFi auto connect off & always scanning off, but you can then dial *#0011# & turn WiFi power save mode back on & it's almost as if those functions done together trains your phone to not boot you off WiFi anymore. This seriously works and definitely helps many i have offered the information to. Me and about 3 others figured out how to do this in a thread about 2wks after the phone was released because the wifi booting us off was killing us. People had told us to just turn off auto connect but that would just stop the pop up, but you'd still be getting booted off from WiFi but just wouldn't be told by the pop up yet you'd know because the page you'd be loading on the browser would just stop loading, or say something your using like Facebook would lose signal & tell you an error occurred. Hope this large posts helps you if you read it or anyone else who stumbles upon it.

You have to actually go into the Google+ app to see if you are signed in, unfortunately it will automatically sign you in if you are not already. So even if you accidentally open G+ or some other program or app causes it to open, you still need to actually sign out of it. Hopefully uninstalling the updates does the trick.

i had a wifi problem with my Note 2 before and now it is better with my Note 3.
Hello everyone,
I have a sgh t999 that receive but not send over WiFi,to explain if using a tethering app the connected device work over 4g but when connecting to a WiFi it seems that its not doing the handshake it said connecting but immediately stop and it gives an error like if the password is incorrect but it ain't,cleared the router,left it open, flashed several times, did every wipe imaginable and modem as well but still doesn't work.
Any help or ideas?
Use the phone by itself without any kind of tethering. See if you can use a browser on the phone. If that works then you will have to diagnose Tether by itself.
I'd Start with setting Wi-fi encryption to open.
Already did, backtrace it to the hardware somehow it got fuzed to the back casing it seems that it overheated and got welded..weird but thanks anyways. I guess my WiFi is done for.

Good evening all.
Has anyone with a G4 on VZW noticed issues with apps on wifi since the latest firmware update? I've called Verizon and been on the phone with them for HOURS to no avail.
The only time wifi works normally is in safe mode. When I'm on wifi, most apps just aren't functional at all. We thought it was some app in particular so we reset the phone and the issue persists. The only thing tech support suggests is giving me another refurbished G4 which will get us nowhere as the new G4 will just be running the same firmware.
This is problematic for me as I work in and out of different buildings on any given day. These buildings don't always provide the best reception. I clamored with Verizon for a different, comparable phone. I spoke with LG and their solution is me sending the phone in with the turnaround time being 5-7 business day which is also problematic as I don't have another phone to use. Verizon refuses to acknowledge it's an "issue" because it's not "wide spread". A quick search revealed that this problem is not limited to just me.
I've exhausted my options. I do not want to spend hours on the phone with Verizon again. I do not want to speak with LG for the same phone again. I simply want a working phone. This is the 3rd G4 that I've had that does not work. The 3rd G4 in almost as many months. What are my options here?
tl;dr This is my 3rd LG G4 that doesn't work and the latest firmware update broke the wifi functionality. Verizon refuses to acknowledge the issue and will only give me the same phone, not a comparable phone. What are my options?"
Yup. Since the update. Wifi on my phone is lagging horrendously.

I spoke with them again today. Their only option is to send the same phone again which isn't going to fix anything unfortunately.
Same problem here (and also with friends who have both VZW and the G4). This exact issue popped up on the LG G3, also after an update. Infuriating that they broke another otherwise good phone. The workaround is to install an app called DNSet. It sets the DNS to Google's, which fixes it.

I am having the same issues. doesn't matter which Wi-Fi network I'm on, it is terrible. Otherwise I love the phone, but this is getting really frustrating
Yeah I'm having the same issue. It's maddening!! Nothing comes through unless I manually sync or have to open the app to get it to sync. How is this an acceptable software update for verizon - who usually requires a high level of quality control on software updates??
The Update broke Notifications over WiFi. It has something to do with IPv6. Verizon PULLED the update because this is a major problem.
Either call Verizon and have them replace the phone (you will get the older firmware 11A back on it)
OR
The fix is to download DDNS or something (It is a VPN service) that routes ALL internet traffic over IPv4 connections. I forget the specific name, but it is being heavily discussed in the "VERIZON UPDATE" forum in the General section.
http://forum.xda-developers.com/verizon-g4/general/update-verizon-t3221673
Read the thread, I think toward the end more.
Almighty1 said:
Give this solution a shot, and what router (make/model) do you have exactly?
You can fix this issue without root by using the app DNSet from the Google Play store. You hit 1 button (the one and only button), and it turns off IPv6, and problem solved.
