[Q] Data only to browser application on 3G - Atrix 4G Q&A, Help & Troubleshooting

It wasn't easy for me, but I got CM7 on my Atrix. The goal was first to get around any throttling restrictions I've been experiencing, second to fix some bugs with the stock Moto rom regarding bluetooth and proximity sensor. On to my issue:
On wifi everything is perfect.
On 3G I can only use data on Browser or Opera and a select few other applications. I can't download apps via the market but I can find them. No speed on my speedtest app, but mobilespeedtest.com gives me 1.4Mbps download speed. This is coming from being throttled to about 150Kbps (little b) and I still have a week left on my plan cycle. So the throttle is fixed but different.
I also had the "mobile data limit exceeded" message that I was able to get rid of by changing the data/data/com.android.providers.settings/databases/settings.db as detailed in this post:
http://forum.xda-developers.com/showthread.php?t=1253963
Before I changed that I was limited to 300Kbps flat on apps (Speedtest, FCC Speed Test), with Browser getting good speeds again at about 1.5Mbps. The "mobile data limit exceeded" message is gone now. I seem to think this all has something to do with the settings in the db above but I know better than to blindly start changing values.
Also of note, I restored my apps + data with Titanium Backup after I wiped, rooted, unlocked and put in CM7. I thought that some data from before may have affected things now. But I had slow (throttled, but it moved) data many reboots after restoring my apps + data.
I also butchered my APN settings in an attempt to get around the throttle monster to the point I had to restore all the default AT&T APNs to get things working mostly right.
I feel I've made a mess of things layering attempt on attempt to increase speeds. Does this problem make sense?
Kernel Version: 2.6.32.57-MB860-CM7-gf1d2072
CyanogenMod-7.2.0-RC0-Olympus-KANG
Build GWK74

An update:
The default AT&T US APN was previously selected, and previously didn't let most apps get data.
Then I read this post: [redacted, google search "Cannot access Google Market application and Gmail on my new LG Optimus One P500 Mobile"]
This suggested it might be an APN issue. By switching to the AT&T HSDPA APN I get data back but at throttled speeds.
After testing speeds in Speedtest.net app and FCC Speed Test app I got 200-300Kbps as expected, but 600-1000Kbps in browser on mobilespeedtest.com. This was misleading. The mobile speed test was only 100KB. In switching to the 2MB full test the speed went right back to 230Kbps. These results plus looking at the graphs the Speedtest.net app gives you shows the traffic is running very fast at the beginning of the download (reminds me of Comcast's PowerBoost).
Back to square one here.

cant download unless im on wifi help?

Well my question is in regard to the atrix radio.
It started today...or at least I just noticed this morning.I run cm7ba2tf with 1.45 kernel.I also installed weekely 3 on top of that.
It has been running great for about for about a week and a half.suddenly my phone has been acting weird.
I had the. 30 radio
This morning internet was great like usual but I couldn't download from the market or internet.apps just wouldn't download.
Wifi did download apps from the market though.initially I thought something was wring with my radio.I flashed. 36 radio and reception was even better websites opened faster but still can't download from themarket or internet.I restored my back up still the poblem persists .I ran a speetest everything is good.my data plan isn't done yet so I don't know why I can download unless I'm on wifi can anyone help me?
Can u download using a web browser? If so its a market problem. You can go into market under yer applications and delete the cache for it ( the data) then reboot. If that doesn't work have u tried wiping cache and dalvik from within recovery?

i had a similar issue earlier today, the market would load but i couldn't download apps, webpages would come up, but applications that required a network connection to request data (e.g. Amazon price check) gave me a network error.
i checked my APNs and switched from 'AT&T US' to 'AT&T US HSDPA', and everyone was happy.
Can't download either through the browser or market.sideloading enabled. Device fully unlocked.flashed different radios to see if that's the issue and factory reset twice.cleared caches dalvik and permissions too.it seems its a network data issue sites liad fast just downloads don't work going to call att tomorrow if I can't figure out the issue

Constant data use after reinstall

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.

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...

[Q] Can't get internet to load?

~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?

Speedtest apps not working on ICS ROMs?

I am on AT&T in the US - and ever since I switched to an ICS ROM (either CM9 or Samsung's official) I am unable to get my network speeds via any speedtest app. I have tried Speedtest.net, Xtremelabs Speedtest, and the FCC Test app.
I will get decent ping speeds, and then the download test hangs and i never get more than 60kbps as a result, but my upload speeds are always very high, higher than they normally are.
Anyone else experiencing the same problem?
I had a similar problem with ICS ROMs. Speeds were very, very low (compared to GB ROMs with KL1 and KI4 modems). The phone was very sluggish when using the browser, Play Store, and several news apps. But like you said, upload speeds would pop real high, to something like 4 Mbps, then drop to near zero. The "Restart Test" button wouldn't come up for about two minutes. I tried about 20 different APN configs to no avail.
Now that I am back on GB, the phone screams. I haven't yet figured out if it is a custom ROM or an ICS modem issue.

Well the phone seems fine in regards to speeds. It's when I run the speedtest that it records a ridiculous speed. I think it must be something with ICS ROMs and how the speedtest app runs tests

jerdog, when testing XWLPU, I had this same issue. Running a test within the Speedtest.net app the download test hangs, and reports a ridiculously low speed when it's finished, but ping and upload seem normal.
Speeds otherwise seem fine browsing and downloading stuff, and if I run a speed test on a web page (like from Speedtest.net the actual web page via the Flash plug-in, instead of the app), the download speeds are likewise fine. It seems it is only broken in the app.
Did you ever figure out what the deal was?
PS- apologies for the super bump.

Thx for the info. I'll try it again next version of ICS I test.
Edit: sorry... Proxy settings from where? The APN?
Edit 2: it was indeed the proxy settings in the APN. once I removed the proxy, the speed test work just fine. Thx jerdog.

Slow 4G Play Store Download Speeds Fixed (kinda)

Okay, so there have been a few of us who've been experiencing really terrible 4G download speeds, most notably so in the Play Store. I'm talking Kilobytes per second here, people. I could transcribe the code and compile it faster than this stuff is downloading.
Anyway, I believe I may have fixed the issue. I've rebooted a couple of times and my changes have persisted through, so I'm hopeful. My download speed went from being measured in KB to MB which made me feel like my phone wasn't trying to operate on dial-up with some free hours left over from one of the thousands of AOL free trials discs found laying about in the early 90's.
So, here's what I tried BEFORE my fix:
-- Various 3G/4G Speed/Network/Signal Optimizer/Fix/Strengthen/Repair apps on the Play Store. Two of those apps actually helped my download speeds for the first app I downloaded from the store; after that the speeds went right back to being dismal and embarrassing. Nothing else helped at all.
-- *#*#4636#*#* to Phone Information and toggled various network preferences. Nothing affected my download speeds.
-- Tried various Mobile Network options in the Settings menu. Nothing helped.
-- Toggled variations of Roaming modes, network types, etc.
-- Flashed back to stock.
-- Flashed to Slim Bean (what I was running before)
-- Tried dirty flashing over the roms after getting everything set up
-- Cleared Dalvik, Cache, Fixed Permissions
-- Completely wiped my entire phone and started from fresh
-- Tried custom kernels
-- Went to the Verizon store and got a brand new sim card
-- In Build.prop I changed ril.subscription.types from NV,RUIM to RUIM,NV. Some google search led me to a forum where someone suggested that. It didn't do anything for me.
-- In Build.prop I saw ro.product.locale.region was set to GB. Changed that to US and rebooted. No change.
Nothing I was doing was working. I was still getting the worst download speeds I've ever seen in my entire life. I swear to god I was getting better download speeds when I was like, 10 years old browsing the internet on a 14.4 modem on a 386 processor with Windows 3.11. I wanted to punch the internet in its e-face with my digital fist.
So, that's when I had a revelation. I just came from having a Razr Maxx that I'd flashed god knows how many different roms and kernels on over the course of the year that I'd owned it. I never had download issues with that, and it too was running on 4G LTE with a micro sim card in it. If that worked fine, then why doesn't this? With that question in mind, I remembered some of the settings I'd seen in the build.props over the past months and one of them stuck out as I was browsing the build.prop for my new SGS4:
ro.telephony.default_network
On this phone, it was set to 8, however I was 100% certain my Razr Maxx has that value as 14. I figured "screw it, let's give this a shot," and changed that value to 14 instead of 8.
When I rebooted my phone stuck at the Samsung boot logo. I had to pull the battery. I booted into recovery and decided to try something different than my usual "Welp this didn't work time to format everything and try again," approach. I wiped Cache, Dalvik, and Fixed Permissions then rebooted. The phone booted up like normal. I ran Speedtest to see if my speeds were still garbage or not. That test wasn't amazing by any stretch of the word. It was something like 6 mbps down, 6 mbps up. I was getting similar speeds before, so I wasn't hopeful. Then, I went to the Play Store "just to see," and downloaded a past purchase.
It started at 50kb and my heart immediately sank. Then, it went to 2 megs. 3.5. 6.2. 9. Download complete. I was hesitant to accept any actual change, so I downloaded another app. Same increased speed. I was happy, but reluctant. I rebooted, completely certain that my old speeds would return and I'd go back to contemplating a full factory wipe and attempt to return the device for another claiming it was defective. After the phone rebooted and obtained its data connection I went back to the store and downloaded another app. FAST SPEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEED!
I don't know what the heck changing that 8 to 14 did or what that value actually represents, but my speeds have remained "fixed". Granted, they're slower than they probably could be, but my Play Store downloads have gone back to acceptable rates so I figured sharing that information with you guys here might help at least one other person who can't understand for the life of them why their new phone refuses to go as fast as it should.
TL;DR: Went to Build.prop and changed ro.telephony.default_network to 14 instead of 8 and my Play Store download speeds went from kbps back to mbps.
My issue has been very similar to yours. Except the only slow downloads I get are when they originate from Google. Running the speedtest app and viewing webpages all show my device is capable of downloading at serveral megs a second. But if I tried to watch videos on Youtube or listen to music I would get constant buffering and some downloads from the market (the more popular one like Angry Birds or Gmail) would only download at about 40k. Then all of a sudden everything started downloading at high speed again. I was overjoyed.
Today I decided to try another ROM and unfortunately after flashing some downloads are incredibly slow again.
I suspect that changing the default_network in the build.prop did not actually fix the issue you were having. Especially since the information I have found about the field suggests it sets your phone default network type to something like CDMA or LTE only after a factory reset of your phone. In any case I have set this same field to 14, cleared dalvik and cache, then fixed permissions and my download speeds remain just as slow.
Well, I'm actually pretty confident it did because I was looking through apns-conf.xml and noticed that every instance of an LTE segment regardless of network (sprint, tmo, vzw) had this value
Code:
bearer="14"/>
. So, because of that, I'm pretty certain that the network type being set to 14 promotes LTE connectivity over whatever the 8 was, which is a value I can't find any reference for in this APN file.
You can try this, which is the actual steps taken for fixing my problem:
Settings -> More -> Mobile Networks
Data enabled [X]
Data roaming [ ]
National data roaming [ ]
Network Mode: LTE / CDMA / EvDo
System select: Home only
CDMA subscription: RUIM/SIM
Press Back, toggle Airplane Mode on then off
ROM Toolbox -> build.prop editor
ril.subscription.types RUIM,NV
ro.com.android.dataroaming false
ro.product.locale.language en
ro.product.locale.region US
ro.telephony.default_network 14
Reboot to recovery
Wipe Cache
Wipe Dalvik
Fix Permissions
Reboot
What ROM are you currently running? At the moment I'm running stock and don't have the options for System Select and CDMA Subscription. I also dont have a ro.telephony.default_network entry in the build.prop.

I'm using Slim Bean.
If you're on Stock, you should be able to do this in Mobile Networks:
Mobile Data [X]
Global Data Roaming Access: Deny data roaming access
Network mode: LTE/CDMA
In ROM Toolbox Pro's build.prop editor I also saw that the region was set to GB. That should go back to US if you're in the US.
Edit: Actually, if you're on the stock rom you can go to Settings -> More -> About Phone - Status or whatever the option is. If you look for network type or connection type, you should see something like Verizon LTE 14 or something similar. That's the 14 I was talking about. If that says 14, you should be good.
