A few days ago I started experiencing this issue my phone. No more edge connection for some reason. I can connect to HSPA fine... but when is time to connect to any EDGE connection it does switch initially and I see that it tries to send data over EDGE but it does not receive anything. After a while it disconnects and when I go to phone properties I only see gprs mode. No active connection and no ip address. I tried flashing anther Rom and the same result. Can't find any information on the web specific to my issue. I think it could be either a bad 2g antenna or maybe the sim ....any of you experienced this problem?

Good day everyone. I have been using my samsung vibrant for weeks now with no problem. i noticed today that i couldnt connect to the internet through my stock browser. so also apps like the xda app and facebook book app will not connect to the internet, while my internet indicator is showing connected (both 2g and 3g).It keeps displaying ""nodes for the connection is not available" on the browser. However, at the same time i have able to connecting and use other apps like ebuddy, yahoomail e.t.c. My vibrant is unlocked and purchased from the US but presently using it in nigeria. My APN settings is still the same way since i started using it and my service provider, MTN, says all is well with my connection. This has occurred three times today... each time i had to switch off and back on, or turn on and off the flight mode for it to work sometimes.
Please, any help on how to resolve this?
Apparently our phones lose data connection when they switch from 2g to 3g or vice versa. To prevent it from happening at all go to settings -> wireless and network -> mobile network -> network mode -> and set it to gsm only to lock it on 2g OR wcdma only to lock it on 3g.
Thanks reform. I have tried choosing only 2g and even tried choosing only 3g...but the problem still persist. I had to turn my phone off and On severally for me to have my internet network back now. Is there any other way I can resolve this?

Hello everyone. Please can someone help me with this problem? I have tried everything possible but the phone kept cutting off my internet connection, but only for my browser, Facebook and xda app. Each time it displays 'node not available for this request' it actually deducted from my data plan but not connecting me. Any help please?

I had absolutely *no* issues with the cellular network whatsoever until yesterday noon, that's when the problems started, all of a sudden.
I started experiencing disconnections from the 3G network intermittently, like every 5-10 seconds it would disconnect and reconnect, extremely unstable. I then put the phone in 2G mode, but I lost my EDGE data connection despite the APN's configured properly. I even called up the provider and had them deliver the APN settings to the phone, but to no avail. My data connection just didn't work, i.e. no 'E' symbol, nada,
Thinking it might be something to do with the ROM, I restored my 2.1 backup via xRecovery, but experienced the exact same issues. Extremely unstable 3G with it's intermittent disconnects etc and NO data connection when it 2G mode. In the 'About Phone' status, it just shows 'Unknown' as the mobile connection type and 'disconnected' in the connection state.
I even went ahead clean flashed the 2.1 .435 ftf via flashtool, but the same issues persist!
What do you think the problem could be? I triple checked with my operator and they say the data services are active on my number, no problem from their end.
Could it be a hardware issue? I unfortunately don't have another SIM I can test with - that said I greatly doubt it could be a hardware issue.
What do you think?
I'm on Wolfbreak's CM 6.1.3 v4.4
Could be a network issue. Do you have this problem at a different place. May be in a different cell. There's always issues initially after deployment of new 3g deployment.
There is rarely a problem with only the data part. As all the protocol stack are not changed or fiddled in these new rom.
So less chance of the rom.

Yeah probably a network issue due to the super important india-pakistan semi final.

Hello everyone!
Just like everyone else I have been waiting infront of the screen for 3 days now to get this god forsaken update and when I finally get it everything works fine exceopt for the WiFi.
on 2.1 I used to get an Internet connection when on my WiFI, Now im connected to the router with full connection strength but I have absolutely NO internet connection, only an evil triangle telling me that I have limited network access.
This has happened to 3 of my phones (All of which are Identical)
And the only even closest similar issue here on XDA has been with the HTCD which dropped the WiFi connection if the signal was too weak, but mine is at full strength.
In short: My phone can do Everything but going on the internet...
What I have tried:
Putting the phone in DMZ
Disabling Firewall in the router
manually enter Static IP settings
anyone else experiencing the same issues and/or know how to silve it?
bump
[BUMP] just bumping this thread because without WiFi my use of the phone is limited to say the least...
Hi i get this too but ojly since the update, i have it working now but its still a problem it sorts itself out if i leave it on for a bit?

I have the another problem around since 2.3.3.
Wifi works fine,
But when not near a Wifi spot cannot access internet /send mms recieve mms , or download internet&mms settings. And this is the only similar problem i found <.<
But on your problem ofcourse might seem silly but im guessing your already tried rebooting/resetting the router? ^.
I beleive you have to be coolnnected to wifi to get settings for internet and mms.
And yes i have tried rebooting the modem but it didnt work so i just connect to the btopenzone signal my modem also gives off

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
Beginnin to regret my decision to get a S3. So complicating!
If you happen to have a case on, remove it and try again.

Turn off wifi, reboot, and turn on?

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.
Hi,
I've searched a lot over the past couple of months but haven't find an answer to my problem.
When I connect to public open wifi networks that have a landing page, phone would automatically disconnect and display a notification saying "Sign-in is required. Network disconnected". This only happens if I turn the wifi on and let it scan and connect automatically. If I manually connect to any such network it'll automatically bring up the landing page instead.
I have disabled network quality check in the settings, but that doesn't solve this problem. I also installed the new firmware with a full wipe and cleared wifi hotspots a couple of times (TB).
Anyone else has had this issue and knows how to solve it?
Thanks a lot!
