3g data transfer issue CM9 - Galaxy S II Q&A, Help & Troubleshooting

I have problem with getting data transfer working on my SGS2. Im using CM9 latest nightly, CM9 kernel and XXLPS radio (already tried few other). I cant get data transfer, my phone is connecting to network provider (which is Orange Poland) i have "H" symbol for few seconds and then it turns into 3G but the icon always stays grey. I tried multiple APN settings so i dont think APN is the issue here. I have tried stock rom and everything works fine there (same APN as on CM9).

[Q] WiFi on, connected, full strength and not sending anything.

So I have my Fascinate running CM7 with the Glitch Kernel, no OC, just for the stock UV, the problem I have is that I can connect to WiFi, everything seems fine and then a few minutes later everything stops loading, as if there was no connection. turning off WiFi and turning it back on helps about 80% of the time but still an issue, the reason this is so big is that at my house we have no reception at all, Verizon sent us a Network Extender but it simply does not work on any phone and I know for a fact that my Network is fine. (We have twin N600s one routing one access point) Additionally the issue is at the local college as well. Any help? Is there an issue with CM7 or the Glitch kernel?
I am having the exact same problem. For example, market will stick at "Loading..." while on wifi but when I turn wifi off, my 3g connection will load market fine. It's so weird because I have full wifi signal and it is definitely not my router. It didn't start until I flashed the glitch kernel. Has to be something there. Maybe there is a workaround?
Im running glitch v13 and wifi works great. sometimes after a reboot ill have to toggle it off/on...

I had that Market problem and it disappeared when I got a new router. A full reset/wipe of router may have fixed it also. Happened on 2 CM7 phones (Droid2 and Fascinate), but not a stock 2.3 Droid2.
On my CM7 Fascinate, I usually also have to toggle wifi after reboot.

[Q] -Device- WiFi problems after changing roms

Hello,
Not long ago i decided to wipe everything from my device and install new rom and kernel just to fresh it up a bit, i want to highlight this: Before i did it, everything was Alright, at least everything related to internet and WiFi.
Anyway, Since i did it I'm experiencing problems with my WiFi connection (at least when I'm connected to my home WiFi router)
Everything Seems to be OK, i have the WiFi icon on the status bar, with at least 1 or 2 lines of WiFi reception (Same like i had Before i changed ROM and everything was alright)
The problem is that some of the time the WiFi is alright, i Can surf the web and use internet apps like Facebook and YouTube, but Most of the time.... Well i just can't... I do have the WiFi icon but the internet doesn't respond...
Another thing, I'm using laptop and connected to the same WiFi network my phone is connected to and everything is just fine... so the problem is with my Galaxy S2 Device and not my WiFi network..
I found a way to solve it and about 60% of the times i disable and enable WiFi my internet works again for some minutes...
Does anyone got a clue what my problem could be?
Thanks!
Try a different modem ..
Try a different rom .
Put your old rom back on .
jje
i Have tried several other modems and nothing changes,
About the ROM i really want to stick with my new ROM and i haven't heard of anyone using it experiencing same problems...

[Q]No data connection.

Im having troubles with my data connection. Basically, there isn't any data connection at all. Im sure that i have the correct APN. I can see the "E" (yes, its supposed to be E, its EDGE) next to the signal bars, but the upload/download arrows won't turn on. Its like its not even trying to connect. I can use WiFi fine.
I live outside US, in the Dominican Republic to be exact. Im using WetDream 1.4.4. Any solutions? Thanks!
Update: I tried with another SIM card with data enabled from another carrier, and the Atrix was able to connect to the data service fine, and i could access to the internet, but still no luck with my SIM. :\
BUMP =D
Try flashing a different kernel. I had the same problem and flashed faux's 1.3GHz unified kernel and now everything is working as it should
Sent from my MB860 using XDA App
I called in for the exact same problem
The problem that was I did not have data on, and I had Data roaming on. So go to Settings > Battery and Data, and turn data on

[Q] MODE/Radio issues - No data/No internet connection SamsungGS2

I have a Samsung Galaxy S2 with Android 4.0.3 XXLPQ.
It's rooted and now has CM9 installed.
Unfortunately for some bizarre reason I have no internet connection.
I've installed a different modem and it hasn't fixed the issue.
APN settings are correct (I've spoken to my network).
Sometimes it works absolutely fine then after a few moments it just won't load anything and I get a 'No internet connection' warning.
Apps won't work either due to no connection.
However I do have a 'H' and sometimes '3G' next to the signal bars.
WiFi is working fine.
Have full signal..
Running out of ideas/options.
I've started from scratch and wiped everything several times and re-flashed xxLPQ but still nothing.
Help!
Same issue

Intermittent Internet Access when not on WiFi

I've recently flashed to Paranoid Android (CM11 base) and when not on Wi-Fi I only get intermittent internet access. (Phone calls and sms still work correctly).
I live in a 4G area, so sometimes the connection strength icon will show DC, H+ or nothing at all and just bars. Cycling the radio on and off works sometimes, and when it does connect it connects fairly steadily.
Phone model is D6503, and country is Australia. I created a backup of the stock ROM using TWRP that came with the phone, is there a way I can take the config files from there and flash them? Would that help with my issue or is this a known CM11 issue with the X2?
Thanks kindly!
I have the very same -or at least a VERY similar - problem, with stock firmware.
I'm running 17.1.1.A.0.402 (Germany/Telekom) and every once in a while, my internet just doesn't turn itself on, when leaving a WLAN, or when entering a "no internet" zone. It just won't start any data connection while phone/SMS services run fine. I have to manually turn it off and back on. Then it'll work fine, right away!
I already checked, there's no new system updates for me to install (even though Sony website says 17.1.2.A.0.314 is the newest, it's not available for my device. Neither OTA, nor Sony PC companion can find any update).
