3G connection on 10.1 - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

Hi..
I just bought a tab 10.1
Somehow the 3G connection is not stable.. it will suddenly be turned off even though mobile data is on..
I checked the apn settings and it is blank.. typed in my own and after awhile it disappears too..
Is this a known issue?
Anyone facing similar issues?

For some reason my 3G data is not pulling through the tablet either. This is from my Galaxy Prevail

Are we the only two with this issue..
Wonder what is the cause:
Sim card?
Hardware?
Software?
At a lost now..

I have a similar problem. On my unit the H+ is displayed only when there is network activity and when there is no activity it turns to 3G. Problem is that this causes about a second of lag on every click on the link before it turns to H+ and then starts to download the page.
Another problem is that the signal strength display in ASU is suck at 4.

Airtel Mumbai users, is the network acting up?

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.

[Q] Problem with running apps when leaving WIFI zone

I'm having an issue that has been bothering me. I run Etrade Pro with streaming data and charts, and when I leave my home, it does not automatically cut the wifi and switch to LTE or 4g. My app stops and says there is no data. This has happened a lot and I wonder if there are some settings that need to assure that mt cell signal automatically kicks in when Wifi cuts out.
ANother problem is that if I approach an area where there is wifi, the phone connects, and i usually get a data issue again.
I also got the same problem when i stream a video while on wifi and then leave the wifi zone, so I know it is not an Etrade app specific problem,
Any advice would be appreciated. What I am having to do is manually shut off wifi and then restart the app when the 4g kicks in, and I know the phone is designed to handle this for me.

I'm not sure this is something we have control over, I was reading over a white paper qualcomm wrote on the matter: http://www.qualcomm.com/media/documents/files/3g-wifi-seamless-offload.pdf
Our phone is 3GPP R8 however, I'm not sure at&t's network supports dual stack mobile IP, so therefor the handoff between wifi and 3g would have to interrupt data.
WHat bothers me is that I just came from an Iphone4 and the iPhone switched from wifi to cell, and my Etrade App kept running. There may have been a momentary lag, but i didn't have to close the app and start it again.
Let me look into it more when I get home. At work youtube is blocked on the company network so I can't test if a video continues between handover here.
WHen I leave my home and know that I am out of wifi range, I still see the wifi symbol on the home screen but it looks like there are no bars of strength. It's like the thing is still trying to draw data through wifi that is well out of range.
Frustrating.

So if the wifi symbol is on the status bar that means the phone is still connected to the wifi (or at least thinks it is).
I was not able to reproduce your problem with youtube when I was home. I started a video on wifi in my home, and then walked out the front door and down the hall until it lost the connection, the wifi symbol disappeared and it just had to re-buffer a little bit after it switched to LTE then the video continued.

Problem with EDGE connection

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?

Hello anuj,
Are you using BSNL broadband? If yes, then many changes that the problem you are facing is because of poor internet signal.
YOU can try these tips to insure it :-
First of all in wifi's advanced settings, uncheck "avoid poor connections"
Second tip is try using wifi with another phone's as wifi hotspot.
If in both or in second tip your wifi is working fine then there is no any problem with your phone, if happening because of poor broadband service.
If you are getting same problem in both cases then it is possible that your phone have some problem.

[Q] Network or software problem?

Whenever I tried to on my mobile data in 2G mode in certain areas it never opens or took too long to start but it's fine again in 3G mode. Is this network related issue or Software problem? Your help will be highly appreciated.
Should be a network problem…… never heard that 2g module can be broken when 3g is still working……
