Hey there,
I've been experiencing data connection issues very commonly since receiving this phone. I've gone from 1.2.6 to 1.5.7 to 1.8.3 to 2.3.4 and after trying all builds, my data (after using WiFi) is very unstable.
The connection symbol will disappear completely after a while of WiFi and won't turn back on until I go to my access point names and "Edit" (just opening the edit page fixes it) the primary APN. Other symptoms include but probably aren't limited too; data turning to upload only.. the up arrow is lit up but never downloads anything and also constant drop outs while in use.
I know my mobile carrier isn't the most reputable in Australia, but this phone is running on their BRAND NEW (weeks old) 850MHz network, leading me to believe that it's a hardware issue (apparent on both Froyo and Gingerbread too) D:
Any help is greatly appreciated
Thanks in advance

i had the same issue, everytime i would start and app that required data i qould have to sit there and refresh over and over, and it would just time out saying data unavail, even though right before i would open the app, data worked fine, so i flashed the new radio and took out my sim card while doing it, reset apn list to default and made sure my phone was on hspa, now shes working perfectly
Hey guys i got a problem.
After flashing my phone normally with Odin like usual all of a sudden data connection aint working anymore. I works fine with wifi, but not without.
It shows 3G/H signal in the status bar, and i see the upload arrow is blinking so it is sending data, but not receiving anything.
I tried googling it, tried flashing various different roms that worked before and original firmware, but nothing helps so far.
I checked the provider info in the phone, and its all correct.
Kinda lost here, hope someone has an idea how to fix it
thx in advance
nobody? i tried everything so far and dont even know why its not working anymore
It's going to be difficult to get much help here because I don.t think most developers have had time yet to get into the innards of the A501. Have you tried flashing back to the original stock ROM? You did back it up before you flashed it with a custom one right?

No nandroid backup, only titanium backup since i never had problems before.
I tried flashing all kind of original firmware now, KH1-3, even older ones, the latest. tried all custom roms that worked fine before.
Tried different sim cards, readded the APN settings etc.
Found out now that 2G is working, but as soon as i switch to 3G etc it shows the signal for that, i see upload but no download, so it basicly stops working.

(Instead of quick reply, i hit thanks first!)
Dial *#301279#. If it doesn't work, dial *#*#301279#*#*
Select 2nd option (Change HSPA revision or whatever).
Then select 3rd option (Release 6).
Restart.
Also, check your APN settings.
Use an app called Tweakker which will configure your apn if u dont know exact settings.
thanks for the quick replies guys.
so i did play with the codes today already, the option you stated i tried but sadly it didnt change anything.
HOWEVER i did choose disable HDSPA completly now, so i am on 3G only and guess what, now it works!!
Speeds are not what they used to be at this location, but that might be due to my data limit so i have to check.
With other codes i found out that while being on H/H+ phone didnt download 1 byte, so i have to wonder why.
With 3G it is working now, but what could the cause be. Used to flash quite often and it always worked, so not sure if thats even related to my problem atm.
Any idea what might cause the H stuff not working at all? I read about the SII getting stuck on H+ etc. before, but all the tricks with rebooting or toggling flight mode etc. didnt work for me
so far, thanks a lot!
Try different modems. Depending on ur location and service provider, atleast one should work right. I'm using KI3 modem without problems.

modem depending on location and provider?
i tried several modems from the original firmware thread under development. they all used to work fine before, now they dont. KI3, KI8, KH3 etc. all nothing :/
Hmm strange. May be you should delete all apns, and configure a new one for your provider.
Also give KG5 and KG2 a try.
i am having a SGS2 with KI3 and sensation rom 1.7 with kernel siyah 2.0. after doing this i am also facing a problem with my data connection. it works but its on / off.
can you suggest come remedies like now please .............
~So I haven't really seen anyone else with this issue so I don't know how to fix it.
My phone likes to randomly not load things via internet. Mostly happens with ATT Data connections, but sometimes it happens with Wifi as well I believe (hasn't happened with wifi in a long time).
I can try and load a page and it will simply not load a thing for a good while (sometimes hours), then all of a sudden it will load like it's on a 10MB connection.
Happens with the internet browser, facebook, and any internet apps. Really gets annoying when I'm trying to browse the internet
I have tried different APNs to no avail, tried turning wifi on/off, changing all wifi settings, etc.
Anyone got any suggestions? (Maybe I'm just retarded and there's a well-known fix for this... at least I can hope right?)
Thanks
EDIT: It also used to never send MMS until I changed APN's if that makes any difference. Just not sure if its a software/setting issue, or if its hardware that needs to be replaced.
There are two APN settings, one of which is used by MMS. It sounds as if your APN settings might have been wrong at one point. What are your APN settings now?
Are you on a different ROM? Do you use a 3rd party app to disable and enable the data connection (to save power)? I know my app sometimes doesn't turn the data back on, so I have to go in and do it myself.
Is this your first phone with AT&T? If so, where did you transfer form? Did you have a data plan with your previous carrier? Did you buy your phone from Amazon?

My APN settings are the "phone" HSPA and "phone" MMS settings from the large thread in this forum.
The phone isn't even rooted. No different ROM, just a stock phone. No 3rd party apps that disable/enable data.

I've had ATT for a decade or so now. Phone bought and activated in an ATT store, and last phone I had was an iPhone, so whatever data plan that used was what I was previously using. I would assume they changed the plan to reflect the android device (if there is any difference), but I wouldn't really know because it is on our family account.
Anybody got any clue? This is really annoying the **** out of me. Also found out my brothers phone (on same family plan) is doing the same thing.

Maybe download Tweakker from the market; it automatically rewrites APN settings for your phone and carrier. CM7 uses wap.cingular, and I used Tweakker to change it from that. Worked, no probs, loved me long time, yada yada.
Thanks, just downloaded it. We'll see if it makes any difference.
Worked great until just now. Lost internet again. Thanks though.
Any other ideas?
i am on AOKP, not sure if you have the options to do the following in stock but try.
1.do you have the option of deleting APN? delete all...
2. force the phone to look for wireless carriers (takes like 4 minutes).
3. click on At&t to registet on it.
4. reboot and the original apn should be there.
I reset it back to the original APN but I dont expect it to help... I had the problem even before I started messing with the APN. We'll see how it goes though.
Any other suggestions are still welcome.
I have a similar, if not the same problem. I have concluded that it's either a modem/hardware issue or network issue. Every one and a while, I'll have to wait ~20 seconds for the internet. This always happens on AT&T data. Once the connection is made, the green and orange data indicators light up and the page loads just fine. Changing the APN's increases my internet speed by a lot, but does not fix the latency issue.
Someday I'll get around to calling AT&T.

Sounds like the same issue to me.
I keep thinking I should go to the ATT store but I really dont feel like having them do a reset of my phone then send me home without actually fixing anything.
Have you noticed what kind of connection you have? I don't use stock, so I haven't thoroughly tested this there, but I believe I experience the same issue. I'm running CyanogenMod 7, and what I see is that whenever the phone drops to 3G, I don't get data. I can force 2G (Edge), which works, and if I pick up HSPA+, I get data. If I'm in fairly sketchy signal areas (bad parts of buildings, fairly far from towers, etc.), I'll notice it flip-flopping back and forth between 3G and H+, with no data. I've never had an issue with wifi not properly loading anything.
I did try switching back to stock for a couple of hours, and it appeared my issues were more along the lines of what you describe, without actually displaying a flip to 3G when I can't get data...but like I said, I don't use stock on a regular basis.
NINJA EDIT: I'm on my second phone with this issue, after getting a refurb due to a USB port going bad. I've tried flashing multiple modems, and have been able to increase my speed, but have not been able to fix the issue when I drop to 3G.

Im in an area where I constantly get 4G or LTE... I haven't really noticed a correlation between the drops and whether or not its on 4G/LTE. I haven't experienced it on Wifi in a very long time though.
Also, the stock APN seems to magnify the problems greatly. Switched back to the Tweakker APN and it runs much better (although it still happens occasionally)
Had the same issue as you, try my guide here: http://forum.xda-developers.com/showthread.php?t=1576199 it seems to have helped many!
Sent from my AT&T Galaxy S II (I777) Killin' it with Task650's awesome AOKP ROM port!
Thanks but the Tweakker APN seems to have solved the internet issues. Only problem now is that MMS doesn't work with the Tweakker APN. Anyone got any suggestions on that?
Hi, posting here to broaden the net a little. I have carbon ROM that i am fairly sure allowed simultaneous voice and data. I.e when making a call on Bluetooth in the car, data for Google maps stayed active. Now that doesn't work but I am sure this worked since the froyo days. I'm trying to pinpoint the cause.
I have sgs2 and tried three different radios with and without ril, nelp3, nelp4, and nels1, but no change to behaviour . But My wife's sgs3 is on vodafone uk and also drops data connection when making phone calls. (Seen by H/3g logo disappearing and being unable to use data when making calls).
We think it's recent but unsure if it's the ROM or something else.
Would appreciate if someone on another rom on a Samsung phone or two can check for me before I restore a backup to check myself.
Also any ideas how to debug?
Thank you
Chris
P.s already tried different and included kernels on both phones.

I am hoping to find the answer to this is Carbon related (CM10.1 vs 10.2 branches maybe?) and not specific to devices. Could you post this thread on the Dev page for that ROM? That way the Devs for the ROM know about it... and may be able to find the solution. Fingers crossed!
So during the last few days I've been unable to make any phone calls, and I don't understand what's actually wrong. There's nothing wrong with either the microphone nor the speakers, as they work in other apps. The problem is that I don't hear other people and they don't hear me I don't appear to have connection problems either since other apps work as usual, with or without wifi. I'm running the Concept 4.0 rom.
It's possible that it might be some sort of water damage because I dropped it in snow the other day but that seems unlikely.
So far I've tried:
-wiping and re-installing the rom
-wiping and installing the Poison rom
-formatting and re-installing
-tried installing without fast dormancy
-restoring back to old backups, where there was no problem, using TWRP
-I tried my SIM-card on an older smartphone and there was no problem.
So does it seem like some sort of hardware failure or some software bug?
Edit: As of now, the phone works however, I've yet to discover why it didn't work in the first place. If you know anything I'm still interested.
Edit 2: So it's been nearly a month since I posted and I'm writing this because I want other people who might have the same problem to be able to fix it. The problem with alot of the roms for the F5121 is that they lack options for controlling exactly which networks to operate on. The fix for this is to enter the "hidden" menus by entering *#*#4636#*#* in the dialer, from there you can fine tune alot of the settings.
On Mobile network settings > Prefered network type.
If you force LTE only and go to a location with no LTE, you won't be able to call also people won't be able to call you.
