(If this is the wrong forum, please let me know, but I think the i9100g forum is just supposed to be for devs?)
I have a SGS2 i9100g that I just inherited from my wife. The stock firmware is crap but with CM10 it runs amazingly well (especially coming from a Captivate running an ICS ROM). I love this setup, but about half the time I go from WiFi to 3G, the data connection doesn't pick up -- I have 5 bars, but they're grey, and there's no letter (H, 3G, etc) there. Sometimes, I'll have 3G for a while, then I'll check the phone to find that it's gone. There doesn't seem to be a particular pattern to when this happens. A reboot usually fixes, eventually. Sometimes I need more than one.
The curious thing: when this happens, I can go to the APN settings and the list is totally empty -- they all vanish, and even if I try to add an APN and save it doesn't show up. A reboot generally brings them back, but not always. I've tried an APN Manager from the market, but it says "not compatible with your SIM" -- I'm on Blau in Germany, if that matters.
Do I flash a new kernel? Radio? I'd like to avoid flashing back to stock or CM9, since I'm so spoiled by Project Butter now

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
Hi, I have a quick question.
I live in Canada and am currently on the Bell Network with the SGS2. Recently I flashed over Lite'ning ROM v. 6.0 and have noticed kind of an odd feature. I have also noted this feature in the the stock XXKG5 rom I'd also flashed in an attempt to correct the issue. (Failed).
Anyway, I noticed that when I lock the phone, or am just simply playing around on it with no data required, the phone stops using the H+ signal and switches to standard 3G. I realize this is to conserve battery, however, the crossover causes a very annoying delay. For example, when I load the browser the phone stalls for a moment to switch to H+, then if I idle for a moment on the webpage (Reading a paragraph, etc) the phone switches back to 3G so I have to go through the 60 second delay again if I wish to go to another webpage. This is very problematic if I am filling out a forum, or posting on boards, etc. I have already disabled fast dormancy, and have done numerous searches so I don't know if I am wording myself wrong or what, but is there a way to turn this nice, but annoying feature off?
Don't disable FD.
Try this, (in keypad)

Hey, thanks for the reply. I ended up finding my UGKG2 stock modem and flashed it over...no more problems...awesome data speeds.
Alright, I rooted my phone and installed CM7 about 3 months ago, and had no problems ever until recently. My phone started force closing the messaging system and my media system. Then, I restarted my phone and it got stuck on the Vibrant screen, before the skateboarding CM7 android. I ended up flashing my phone back to the Samsung Vibrant T-959 stock using ODIN, but since I have Cincinnati Bell, I had to use T-Mobile's stock. My phone works perfectly fine except one thing... I DON'T HAVE DATA! I can't get online or access the market... It says I have no internet connection. Can anyone help me?
If there is something out there that I can use thats better than this T-Mobile stock software, please let me know... I'm open to anything at this point. I just want something stable and clean.
This sounds like the problem I have everytime I flash a Froyo ROM of any sort: I lose my APN.
You can check to see if that happened to you by going to Wireless, Mobile Networks, and checking to see if any APN is needed. If it says something along the lines of "Enter New APN?" or some such (I'm on MIUI at the moment so can't be exact), then your APN got wiped. Cincinnati Bell lists the correct APNs for the Vibrant on their website.

Go there, and enter both the WAP and MMS APNs, selecting the WAP one. Also, to curb another common problem, don't enter a Proxy for the WAP. It causes major browser slowdown and you data works just fine if not better without it.
did u try....
Taking the sim card out? Had the same problem, I took the sim out and put back... problem solved.try that
Hey, I'm having the same problem. Mine shows that I am connected and have full bars with 3G or H access. However, when I try to use the browser, gmail, market or any other app requiring data, it says that it fails to connect. I've been struggling with this for a couple of days now. I've already tried removing the sim card and resetting everything. Any help would be awesome, thanks!
Hey guys
I just installed the leaked AT&T ICS (the CWM version that's been posted), and so far everything's generally great.
However, ever since I upgraded to ICS, my phone has been downloading data like crazy over WiFi. Oddly enough, this has happened on my phone before as well when I was using GB, and I believe it also occurred then right after a reinstall.
It's incredibly annoying because whatever the phone's downloading, it seems like it's using a lot of bandwidth because any other internet-related activities I try and do take *forever*. I've rebooted the phone several times, tried stopping every service that I can, and turned off all auto account sync stuff. It's been several hours since I installed ICS, and it's still going.
I'm going to let it sit overnight and see what it's doing in the morning, but even if this is only a temporary problem it's REALLY annoying. Especially since if it's not done doing whatever it's doing by morning, I won't be able to use cellular data on it because I only have the 200 MB plan and don't feel like losing my entire volume for the month because I can't stop my phone from downloading.
Any ideas as to what's causing this? Like I said I'm pretty sure this isn't an ICS-specific problem because it happened under 2.3.4 also, I just want to be able to shut down whatever's doing this excessive downloading. And I'd love to know *what* exactly is being downloaded that's it's taking so long and using so much bandwidth.
Thanks for any help you guys can lend
If you do switch to data to let it pull it down, you can use the data usage in the settings to see what app is doing it. My Data Manager (free in the Play Store) can also monitor data, on cell data and wifi. That would also tell you what app is doing it.
I would guess you either have a ton of data in your Google account, such as contacts, calendar, Gmail, or you have an app that is trying to sync data down. I'm guessing you are restoring apps, then notice the data draw. Think about any apps you have that may sync data back and forth. If you sign into your Google account at initial set up, it should (depending on settings) automatically download and install your apps. But, that should be apparent, you should see the downloads as it does them app by app.
All that is based on guesses of what I would consider "normal" behavior after installing a new ROM.
Good luck tracking it down. :thumbup:

Check what is using it, and listing what APKs you added might help.

Or avoid all that and use the native ICS data monitor.
The weird thing is that I hadn't really done anything to the phone when it started using all the data. My Google account doesn't really have much in it (don't have a ton of contacts, don't use it to back up apps/etc.), and I think the only things I'd done app-wise were updating a couple preinstalled apps (Facebook and Maps, I think), but I hadn't installed anything new yet.
I installed My Data Manager, but it looks like it's already done whatever it was doing. Though, even now the download arrow is constantly lit up on WiFi, but I think whatever it's doing now has something to do with the network I'm on (dorm room) as I've noticed almost constant non-zero download bandwidth being used on my desktop as well when it's on the network. If I turn WiFi off now it isn't constantly using cellular data any more, so thankfully it looks like it's finished with whatever it was doing and the constant WiFi downloading is a network, not phone, issue.
On an unrelated note, I was going to reinstall a tethering app, but figured I'd give a try to the built-in tethering first (don't have a plan). On GB it wouldn't even let me start up the tethering without a plan IIRC, but under ICS the tethering not only starts up, I can even connect my laptop to it. Unfortunately I couldn't get internet access on my laptop though, so I'm guessing there's still a restriction on it. Just found it interesting that you can actually enable the tethering without a plan now.
But there's a more serious problem, however. Is ATT clamping down on third-party tethering? I used to use Barnacle WiFi Tether, so I went to install that from the market. Well, Play tells me the app isn't able to be installed on my device because of carrier restrictions (lame). No problem, I figure, I go to their website and download the apk from there and manually install.
Well, when I try and start tethering using Barnacle, it says "WiFi: Could not set ad-hoc mode of wlan0: Operation not supported on transport endpoint"
Does this mean I'm screwed? Will any third-party tethering apps work? To be honest I'm not really into trying out 5 million different ROMs on my phone and don't really mind TW at all, so I'd prefer to keep it stock. But I use my phone overseas and need to be able to use tethering, and if ATT is really clamping down on third-party apps then I'll be installing a completely stock kernel once one's easily available.
Thoughts? Anyone else experimented with tethering on UCLC2 yet?
Well, never mind regarding the tethering stuff - I'd still be interested anyway to know if ATT is trying to actively prevent you from using it in ICS, but I just flashed the SHOstock2 ROM and I gotta say I'm blown away. Even after using it for a half hour I'm pretty sure I'll never go back to stock again (I'm sure most of you would say DUH to that), has everything I'd want in a ROM and nothing I don't. Default tethering works right out of the box too, so I don't even have to worry about installing another app.
Only kinda weird thing is the data indicator keeps switching between H+ and 3G (I'd post on the actual ROM thread but I don't have 10 posts yet...). I'm only on the 200 MB data plan so I switched it to the wap.cingular APN, but even after doing that it still switches. Data seems fast - and I'm not one to be super-concerned with data speeds since I'm mostly just checking e-mail - so it's not a huge deal, but figured I'd mention it anyway.

The data switching is normal. The device idles on 3g to save battery and kicks up to 4g when it needs the speed. Stock roms hide this behavior by showing the 4g icon even on 3g

I never thought to press the menu key in there, there is no indication there are more options. By default it doesn't show wifi data, but on my TouchPad running CM9, that's all it shows. Guess I shouldn't have assumed the ICS wouldn't be without menu use fragmentation like every other android version.
Yeah, the data switching on a custom ROM is normal. Just showing you what the phone actually does. It can save power by reverting back to the 3G vs H when you are idle. The first thing most custom ROMs add is tethering on the built in method. If the leak let you start it up, I'm guessing its incomplete. I would bet att does the same in ICS as GB and has an app to check your account before letting you turn on tethering. Att can detect tethering on the back end too, so if you are caught they warn you first, but you can end up being put on the tethering plan if you keep tethering.
Sent from my Galaxy S II (i777)
Ahh, thanks for the info on the data switching, never knew about that!
I don't use tethering in the US, but I do overseas, which is why I was concerned about ATT blocking tethering apps. However, I realized it's probably not an issue anyway because I'm guessing that tethering wouldn't be blocked with a non-ATT SIM card. Anyway, SHOstock rocks, so it's all good
Also good to know that ICS can monitor WiFi traffic by default - didn't think to hit the settings button on that screen. I gotta admit, that's one huge interface design flaw of Android. There should be some kind of indicator on the screen when there's a menu available, really poor interface design choice to have to hit the menu button randomly to see if any menus are there.

With new ICS developed devices, most don't include touch buttons... The Nexus for example (using on screen buttons) only shows a menu button when a menu is available...
Cheers.
ALSO- I also noticed what appears to be constant "spurts" of Wifi data usage as well (at least according to my Wifi status bar indicator)... It doesn't seem to affect my Mobile Data, and every data monitoring App (including stock ICS data monitoring) doesn't show the culprit, which leads me to believe that we may be dealing with a system app that is accessing data in the background almost constantly... But only on Wifi. Maybe a location service, or something to do with Syncing? I say system because not even stock Data Monitoring is recognizing an app using data...
Another reason I say this is because I pointlessly wiped my device and started over due to this... "bug"... Only to find that running stock CM9 (with no installed apps) my Wifi indicator still led me to believe my device as downloading spurts of data constantly.
I haven't been able to narrow it down, and am hoping that the issue is fixed in a future software update. - But it is more than likely not an app, just an ICS/CM9 bug.
UPDATE- Just checked a Samsung Epic 4G running CM9 and the bug isn't there... So, it's something specifically within our device and ICS... Again, maybe a System app or Kernel bug...
~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!

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?
