App Blocking 3g Access

I currently have something on the phone not allowing 3g access. I can't seem to figure out what it is, but I believe I narrowed it down to an App. I did a wipe and clean rom install and 3g was working fine. I did a titanium backup restore of all apps with data and now 3g isn't working again. Anyone know of an easy way to pinpoint what is blocking my 3g? I tried ending all tasks in advanced task manager, but I'm guessing the phone would need a reboot to bring back 3g?

Have you check you settings-wireless & networks-mobile networks-use only 2g networks?

ya I tried using only 2g network, I even tried researching the network and it finds tmobile in the settings. I even went as far as getting a fresh sim card prior to wiping the phone. Somehow after an app/data restore from titanium back up, tmobile internet no longer works still. It's why I wiped in the first place.

1) Double check your APN settings in settings > networks > mobile networks
2) In dialer, dial *#*#4636#*#* > choose phone info > scroll down > verify that 'set preferred network type' reads WCDMA preferred.
3) Also in settings, make sure you didnt set 'use 2g only'. Same location as #2 above

Thanks for your help. I actually just did a nandrestore from an image I had that was a week old and internet came back, so it has to of been something I done within a weeks time. I just hope I don't end up hitting the app that stopped it, if I think it was one, because thats the only thing that makes sense to me.

I have your same problem could you be so kind as to attach the img you put so I try too? thanks

Then you will have his phone.

you mean....?

i Think i have a similar problem... I turn 3g on and after half an hour i cannot access the internet anymore... The sign in the notification area shows the "sent arrow" blinking but the receive arrow does nothing... I have apndroid to control my 3g usage... I unistalled it, did a reboot but again the problem persists... Do you have anything in mind???
I forgot to mention that the exact same thing happens with 2g network as well

When someone does a nandroid backup, it backs up all the data on the phone. All of it, if you restore it to your phone, you will be logged into google as him, you will have all his contacts, messages, settings etc. If one of you downloads something, it may download on both machines. The only way to fix it would be to wipe both of them.

i have the same problem. two days ago its working fine. i just turn on turn off the wifi and it just works again.

Can also try turning the airplane mode on/off. This problem occurs if you use APNdroid or similar, or toggle mobile connection on the Desire ROM.

tired of trying and try to wipe, reset, several rom, so I decided to send it to HTC in England ... and the problem is which has the bootloader unlock my ...

totally disable mobile Data

so im leaving the country in a few hours and taking my G1 with me, been looking at solutions to effectively disable ALL mobile data, without affecting Voice. basically i'll be using a PPD SIM and dont want random data charges munching my minutes.... all sense roms have this option built in, but heres a few problems, 1.5 has no nav in maps, and i plan on using it over WIFI, 2.1 sense is just too batt hungry and unstable to possibly wind up lost in a foreign country where i speak 0 words of the native language.
from what ive read APNdroid doesn't quite do it.... is there any way as root i could effectively "break" the data connection?
or alternatively does anyone know of SoftBank in Japan offers ultd Data for PPD SIMs? if so how much? and any ideas weather i'll be able to get 3G or only EDGE with my T-mo Radio

try dialing *#*#4636#*#*
then "Phone information"
menu button
"More"
"Disable data connection"
Do the same to turn it back on.

id read about this fix as well, however it appears it doesnt hold across reboots, ima be here for a couple weeks, i need a more permanent solution...
is there no way to physically remove the drivers that control the mobile network via ADB or maybe pull it out of an update.zip before flashing?

I think the option below it is "disable on boot". You could try that.

change the APN settings, or get a program called quick settings from the market. either way is a quick fix.

the set on boot option will reset its self after the WiFi is cycled... and of course without data i'll be using wifi as much as possible.... so far APN droid has served me pretty well, however i've still cought glimpses of that 3G icon, so if anyone has any ideas im all ears
i remember some early Haykuro ports that had improper Radio drivers and had no data connection, so if anyone knows what files those would be thats really the key im looking for

bump/update
the only time i see it trying to pull data when the APN is disabled, auto sync is off, and bkgrnd data is off, is in one of 2 cases, immeadeatly after i cycle off wifi, i see the 3g icon for a split second, and sometimes when im in Market uninstalling something
ive come to the conclusion its probably easier to just leave WiFi on and not touch the market unless ive got a WiFi signal, but now its almost a matter of i know that theres got to be a way to do it (seeing as with Root, i should be able to "break" just about anything) and its eluding me....
if anyone has any clue as to what files control the data "drivers" or whatever, im sure i can take it from there, just need a push in the right direction (or directory, lol)

Go to APN under Networks and just delete all the APNs.
Alternatively you can make a new one with bogus information and select it.

... did you even read my post.... that was my first try, days ago...

Loose 3g data when Wifi is enabled with CM6.RC1

There have been a few discussions about this, but I have yet to find a solution that works for me...
I flashed CM6 today and now I'm finding that when I enable wifi, my 3g data connection is lost. Not sure this is really a CM problem, I just want to find a fix.
My setup:
Nexus One - CM6.RC1 - FRF91

what do you mean it's lost.. when you're turning Wifi on, that's the whole point (that you want to use your Wifi connection for data, and not your mobile 3G data.) Maybe I'm not understanding you?

Even with wifi on you still need 3g data to send and receive MMS. I can't replicate this problem, though, so I'm afraid I'm not much help. All I can suggest is trying a full wipe of everything but battery and rotate stats and try to flash it again. See if that helps.

It works fine for me. Are you sure you are confussing not having both icons in the notification bar with 3g being off?
I answered this question a few months ago too.

Your 3g is not lost, it just hides the icon. Go into settings and look what network you are still connected to for yourself, it will still say 3g. If you were to send or receive an mms the 3g icon would briefly pop up, send the message, then disappear. Your phone is working just fine

thanks for the help... @roger, you are correct, i didn't realize that the icon was hidden vs. actually turned off, nor did i think to go check the actual service rather than rely on the icon

[Q] download issues with the captivate

Hello,
I am relatively new to android phones in general so I apologize in advance if this is a common question (though a quick search didn't find anything). My question is this: Many times when I try to download something using the stock android browser (I have also tried dolphin browser with similar effect) the download fails, especially if it is a particularly large file (even more so when I try to do something else while its downloading). Is there any way to fix this or am I doing something wrong when it comes to downloading files? On top of that I have also noticed that sometimes when I try to download a file (lets say a .apk) it will say it downloaded the file but will have really only downloaded 10kbs of data or so, Obviously I get errors when trying to open them. In regard to the small file sizes, I know that the problem doesn't lie with the sites im trying to download from, because I have downloaded the exact same files with my computer with no issue.
Also one other quick question about how the Captivate (and android in general?) handles wifi and 3g. I've noticed that whenever I turn WiFi on and connect to a network the captivate refuses to send data through it's 3g connection. Normally this would be a good thing but there are certain apps that require a 3g connection. It also becomes a problem when I want my Captivate connected to my home network since the network isn't connected to the internet (stupid cisco NAC agent, if any of you have any Ideas on how to get that working through my router i'm all ears.). Simply put, I want my Captivate to be able to connect to the network to view files but to still be able to use the internet through it's 3g connection, is that possible?
Thank you in Advance,
Felipe Breyer Jesus

I dont have issues downloading files. But i dont leave the download screen until its done. Could be your issue. As far as wifi goes it shuts off 3g. Have you tried starting wifi. Once connected turn on airplane mode. Then shut off airplane mode? Might start 3g again?

Um.. some websites will not allow you to download using your phone due to some kind of crazy restriction that the web server has. I remember Design Gears had to tweak a web setting to allow people to download ROMs directly to their phones.
And.. I'm not an expert but.. by turning on wifi - 3g service will get stopped. You would probably have to do some serious hacking to get both to run at the same time... and that is IF you can even run both services at once.
You were saying you were having router issues as well... but do you have internet connectivity with your computer? If so you can always just download the files from your computer...?

Wi-Fi Not Working (Nookie Froyo)

My wifi keeps cycling between on and off on my Nook. Sometimes it will stay on, and appear like it wants to connect to my wifi, but all it does is get stuck at the "obtaining ip address" portion of the process.
What do I need to do to remedy this?

I found the same problem, I can say that the Froya rom is almost perfect for me, except the problem that the WIFI lost and cyclical on and off. I tried many ways recomeended but no luck.
If someone can help to solve this please !!!

I had this problem before, and it was because of an improper flash. I skipped a step of wiping data and cache before applying the flash.

Settings -> Date & Time -> UNCHECK Automatic
that solved most of the problem for me.. its still unreliable, but atleast it doesnt get stuck in a loop anymore.

Maybe you should delete all networks registered on your phone. in case you have chosen to remember some WiFi networks in the past.
Then turn off/on your wifi network
