Data Connection Problem - Galaxy S II Q&A, Help & Troubleshooting

Hi
I am having problem with my internet (data) connection on my phone.
What's happening is that i start using the internet connection with no problems then at one point i lose data connection - all other serviced work well - sms / calls.
In order to get my data connection back i either have to restart phone or else go to flight mode and off flight mode again.
Is anyone experiencing a similar problem?
Ken

Hi Anyone else having the same issue or not having such an issue?
Since i am still not sure whether this is a phone problem or a service provider issue?

[Q] 3G-2G switch data problem

I experienced this problem with two X10, when you are on WCDMA only mode and data connection is active, try switching to GSM mode only. Your data connection will not restore until you enable then disable Airplane mode.
Anyone having this same problem? Both X10 have different manufacturing date and tried it also with different provider but same results
Mine doesn't do that. I do this all the time when I don't want to get over my limit in one day which is 1GB of data...
Mine does the same thing. I have no problem switching from 2g to 3g. But when I go back from to 3g to 2g I have to turn on airplane mode to enable data again. I am running GB 2.3.3 JVB. But the same thing happened on 2.2.1. Being searching like crazy and havent found any solution. Anybody know how to fix this? Maybe its a network problem not a phone problem.
Hi there.
I have the same problem. Do you have any news?

[Q] WCDMA only mode = no wifi connection

Hello,
In my area I find that I keep jumping from HSDPA to Edge and back constantly, which breaks my data connection briefly. It's very annoying.
I found that changing the setting to WCDMA only fixed this, and did not result in loss of data connection - it just kept me where I needed to be.
Only problem is at my house, suddenly I could not connect to my wireless internet no matter what I tried. I could connect to the neighbors slower open internet connection, but not my own. Tried everything. When I set it back to Auto mode, I could connect again with ease.
Any suggestions for a way to be WCDMA only and still connect to my wireless? I don't understand networking well enough to help myself.

3G not connecting?

Hey guys,
Just curious if anyone else in the Boston area is experiencing a 3G connectivity issue. It was working earlier today I think, but in the last hour, I can't connect to data...at home, now on Wifi...
EDIT: Nevermind..for some reason data was disabled...
No problems with data connectivity in Quincy. I havent had a hiccup at all today with the phone.
Yeah, it seemed like my data was disabled for some reason...went into settings battery and data and the data enabled on mobile network was off...turning it on fixed it...it was kinda weird.

[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……

About data connection after WiFi off

Hi all, I have encounter this problem since 2 month ago.
There's a way to reproduce it:
Turn WiFi on and you have to connect to any router, then you can keep data connection on.
After 30 min to 1 hour, turn off WiFi. Now data connection should working, but in my case, I can't.
Thought the data connection is enabled, it just unable to connect to the server...
I have to enter "test mode" to turn off Wireless connection and turn it on again to fix it.
Or to turn on/off airplane mode to fix this issue.
However, I've seen no one complain it here.
Is there anyone have this issue and how to solve it?
P.S I've tried all the ROM and Modem from v24p37 to v24p50
