suddenly internet access is not working - Galaxy S II Q&A, Help & Troubleshooting

my ROM is Jellybam, 5.1
since yesterday i havnt been able to connect to WIFI or to my mobile network.
for example the wifi, it says that it has connected to my router, but i still can't surf the internet.
same thing with the mobile network, it shows on the top of the screen that im on "H+" or "3g" but i still can't access the internet.
I've never had such a problem..what to do?
thanks.

U tried play store?

check the access point on your phone to see if is pointing to the apn for your provider. To check access point go to menu - settings - more settings - mobile networks - access point names.
On wifi check your router to see if it sees your phone. The router may need a static ip or the router version is out of date and doesn ot support the wifi of your phone.

already done it. my mobile network settings(APN) are fine.
and i even tried to connect to my friend's wifi and still nothing. it connects, but there is no signal and i cant use the internet.

try calling your provider, your account may need to be reset to get rid of the problem with the phone internet.
To check on wifi you may need to try another kernal as there mabe an issue with the wifi files in the kernal.

but how is it possible? i had this ROM for 3 weeks and never had a problem with my internet connection. and i havn't changed my kernel or my modem since i flashed the ROM.
and the internet access and the WIFI problem had started at the same time. so i assumed that there's just 1 problem that causes the wifi and the network problem.

internet and wifi are seperate problems it is a coincident that they both failed at the same time.
Wifi software issues are located in the kernal. Internet issues could also be kernal or firmware related. These issues could strike at any time without warning.
We know it is not a hardware issue as it connects, so it must be a software isuue.

[Q] strange wifi problem

I am on bionix 1.3.1 and have noticed that whenever I turn my wifi on it seems to not allow me data access. My web browser will not connect to a page, market won't load, and any downloads that were in progress will fail. it's as if turning on the wifi is overriding my data connection and blocking it. It says that it's connected in the menu though. Any advice?
Thanks
Edit: I just noticed when looking at my phone stats, that when I turn on my wifi my mobile network state says disconnected, and it connects again when wifi is turned off.
Also, I have an airport extreme and a mac, perhaps that is my problem. I've scoured the internet and found a bunch of info about this problem, but haven't found anything that works yet.

Im sure someone will correct me if Im wrong but if you switch from wifi to 3g while downloading the download usually will fail because you were using only wifi to download the content and when that turned off it doesn't just switch to using 3g you have to manually retry the download using 3g .... when wifi and 3g are on wifi doesn't speed up the 3g instead it does the internet related work and the 3g does the text and phone call related work
that makes sense, thanks. as for the connection problem, it is definitely mac related. my wifi seems to work on other networks. I just need to figure out how to make it work with the airport. It's just weird to me that it says it's connected and shows signal bars, but won't access the internet.

so is the new problem that the airport extreme won't give wifi to your phone or that its not working at all
According to my phone I am connected via wifi to my network from the airport, however, the phone cannot access any internet functions when connected. When I disable wifi, it works fine with 3g or edge. It seems to be something with the settings on my airport, not the phone itself.

[Q] S3 Wifi, Roaming and Time Issue. Please help

I am away form home now and facing some frustrating issues with my new S3.
1. I cant connect to any WIFI network though the WIFI connection has very good signal strength. I always get the msg 'Network disabled. Poor Connection'. There is nothing wrong with the WIFI as i can connect it with my laptop and my buddy could connect to it using his IPhone.
2. My roaming time is completely wrong. It does not follow the time of the country I am in. It is showing the same time as my home country network. Shouldnt it automatically detect the network and shows the correct time like Iphone?

1. Restart the router & try just using 2.4Ghz in settings > wifi > advanced
2. Ensure: menu > settings > date & time > check [auto date & time] and [auto time zone]

2.I have already check both auto date & time and auto time zone earlier. But the problem still persists.
Please help

Hi, this is my first post, as I created my account specially with the purpose to answer you.
After being faced with the problem all day and reading all possible materials on the topic in google and here, my dad walked in and asked me why he is not able to connect to our home wireless connection.
This was when I retrieved my hope that the problem is not in the phone. And it was not! My iPhone, my laptop were able to obtain a internet connection in contrast to my other laptop and my S3! I restarted the rooter and everything was ok! Everbody got their internet dose !
So, most probably it isn't you!
Also have wifi problem, except it tells me it's an authentication error. I cannot connect to the WiFi unless I stand right next to it. Can't connect to WiFi anywhere (if you think it's the router in my house), even though the device detects the router. Sent it back to Samsung.

Hey, I experienced the same problem. But in my case, I am able to connect to the AP, if I am using a static IP address in the SGS3 instead of DHCP. Same router, no settings changed there. Just configured a static IP.
Cheers,
Jaegermeister
Same problem
Tried everything still not working, took it back to samsung they said it's working fine any other device is connecting without a problem but the S3 wont (i have 15 S3 with this problem)
Thanks
Bring back the phones to Samsung!

I'm also frequently getting the "Network disabled. Poor Connection" message when at home. I have 2 wifi routers:
- Buffalo WHR G54S
- Draytek 2920n
If I turn wifi off/on on the S3 it sometimes resolves the issue, but not always. Sometimes after turning off/on it shows a status of "Connected"but there is no internet connectivity. If I then switch to the other router I can sometimes (but not always) connect successfully.
I'm running Checkrom v5.5, and have tried both the Perseus and Siyah kernels - both have this problem.

Problem with cm9 and wifi

Hi i went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

[Q] Problems connecting home wifi

Hi, I have a Galaxy SII from AT&T and I have problems trying to connect the wifi at home, When I tried the mobile is connected just for a few seconds and then suddenly it is disconnected, but the wifi network still displayed. If I go to youtube, fb, twitter or any other application the icon shows the green arrow saying data is sending, but the orange arrow is not flashing. I tried to connect to other wifi (public places or friends) and it is working fine without disconnecting. One thing I notice is if I try to connect at home and start tune in, I will be connected always meanwhile tune in is running. My ISP is Century Link and my laptop and ipod don´t have problems, just the galaxy. I called the ISP and they said everything is fine with my signal and my modem. No I have the app wifi fixer running just to reconnect each time the mobile doesn't have wifi signal.
My galaxy is unrooted, running Android 4.0.4 Baseband I9100XXLQ6 Kernel 3.0.15-1114882 build number imm76d.xwlpy
I hope somebody can help me.
tried erasing your home wifi settings and re configure it?
might be a conflict.
Thank you, but i did it also i removed all the wifi network and still the same problem

This will be hard to debug without further information.
You should try to take a look at the log files of your phone and your AP. On your phone use CatLog to record what is going on when you try to establish a Wifi connection. On the AP side the manual will tell you if and how you can access log file information of the AP.
i'm still smelling ip conflict....this might not be a phone problem but a router problem.
might wanna look into that.
FYI, though your question is general enough that an answer provided here may be relevant to you, this forum is for a device that is different from yours.

My Galaxy is SII I9100 unlocked, that's why I posted here my question. I don't have problems whit the carrier, it is with my home wifi only. I removed all the other saved wifi connections, made a factory restore, but still having problems. My modem is brand new, I have 2 weeks with it. all other devices connect correctly and don't loose the connection, even my Ipod, also I set a static IP to the sgsII without results. I only have internet for at max 40 secs then the wifi icon is showing just the green arrow (sending data) but no orange arrow (receive data). My only "solution" at the moment is us wifi fixer, I installed the cat log as one of the user responses but I don't know which word I have to track there are many WIFI.
try setting your router to dynamic assignation. I'm pretty sure that is an IP conflict.
Problems started - with the phone only - around the time you got the router?

Hi my router is in DHCP mode, I only have 3 devices connected, my laptop, Ipod and galaxy sII, the problem is present only with the phone, I followed this video and changed the wireless channel and the internet holds for a while but after 5 mins I don't have any response from the router. just the green arrow. Modem model Actiontec C1000A attached are some images of my router configuration as well the log, it shows the elapsed time between connection and disconnection it is because wifi fixer checks the connection and
tries to repair it if it not possible then turns off and on the wifi
I have the very same Problem! Internet works for a few seconds or minutes. Suddenly all downloads etc. stop and only one arrow in the wifi symbol is flashing. Tried a lot of things now. Have no problem with other networks.
What i tried:
g -> n (but one of my devices don't supports n =( )
20 to 40 MHZ -> No connection @ all
Fixed or dynamic ip -> same result
All other devices work great with my thompson router. Disable and Enable of the WIFI give's me a few more minutes with connection. Programmed now in tasker that wifi is disabled with display of...
Greatz

You said it was "from AT&T", so I assumed you had an SGH-I777, which is the model AT&T sells. I stopped reading, so I missed where you said it was an i9100.
Anywho, try changing the channel on your wifi router.
Look at this guy & his S iii; doesn't ring a bell?

So did you try all the other ones?
I tried with all the channels, still same problem, also with static IP and the problem still there, my only workaround is connect to wifi, start immediately tune in, and the mobile is able to receive emails, whatsapp, etc. but if I tried youtube, then tune in is disabled and the video starts the streaming but suddenly the mobile is not getting more data from the router, I'm able to watch just 1 video 2 min long

What should bother you is that you can connect to any wifi network, but your home's.
Burn that router down!
....or try another one.
yes, I will call to my ISP and ask for a new one. Sometimes I want just to watch some youtube videos without turn on the laptop or simply use my wifi to save some Mb from by dataplan

You should go to someone you know who's got the same ISP than you first, try it there. If it works it's your router, If it doesn't it's you ISP config that's creating a IP conflict with your device.

[Q] Losing internet but still connected with wifi.

My internet problem.
My internet drops between a couple of minutes till 1-2 hours after I connect with my wifi. When I reconnect it works again for a certain time.
I'm still connected when my internet has been lost, but I can still acces my lan.
When I connect to the wifi of my modem there is no problem at all, only when I connect with one of the 4 routers that are connected to the modem.
This problem is only with the use of my phone, other phones/laptops don't have this problem.
The phone is a Kingzone K1 Turbo (chinese brand)
Options I tried:
On the phone:
- I had the same problem on the Zopo zp998 (uses same motherboard)
- Tried with manual dhcp and dns server on the phone.
- Tried google dns server.
- Other devices don't have this problem.
- Used wifi fixer
- Reception and speed are higher dan average.
On the router(s)
- Changed the wifi channels and tried both 2,4 as 5ghz.
- Tried on 4 different routers I'm using.
- Turned of routing function and dhcp release on routers, and tried it with it turned on (different ip combinations)
- Used different security settings including no security
- All firewall settings are turned off.
None of these options have helped untill so far. Who has the same problem and who can help out.
For now I use onlt the modem to connect, but the wifi doesn't reach other parts of the house.
fixed..
Called my internet provider to change the modem and the problem was solved.

I had a thomson modem before. then i got back to a samsung horizon box, after it there was no problem. Recently I change back to another modem again an ubee. I don't have the problem again, so it was something strange in this thomson.
So when I connected straigt to it, it was all fine, when using a router to connect it got this problem.
