data network drops.. - G2 and Desire Z General

I have a strange problem on G2. Somehow sporadically data network gets disabled, phone radio stays on. The only way to get data back is toggle data enabled in settings.
What could be wrong with the device?
Thanks!

Are you rooted? If so, what ROM/Radio?
If not, have you selected to make sure your APN settings are correct? Does this happen on 3G only, or does it happen on EDGE too? Could be any number of issues.

I had this several times last week. The data connection was dropping and where it normally would have just reconnected it wasn't. I had to re-enable it in the settings. Voice and text were fine. Didn't try it over a reboot.
I put it down to the network issues, the service status page was showing data issues in my area. I guess when it tries to start a data session it gets a deny back so stops trying and disables data. Underneath I think its a PPP session a bit like dial up internet.

Not rooted.
It happens only with 3G. Never seen data dropping on 2G/Edge.

Data Connection Always Connected

I am not sure if this is even a problem, but before today my data connection to t-mobile would only connect when needed. For instance, if I was home then I would be connected to wifi and my data connection would turn off by itself, but would still connect if needed by a program, or whatever, that can't use wifi but needed the data connection instead. Like when I sent a MMS message for example. Then after the message was sent or whenever the program was done with the data connection then it would automatically disconnect where I would continue to use the wifi connection. Also, if I left the house then I would automatically be switched to the data connection as the wifi signal went out of range.
This is the way I liked it. Today it had changed the way it behaves. Now, the data connection stays on no matter what and I have to manually turn it off in the comm manager. Also, everytime the screen turns off and the device goes into sleep mode, or whatever you call it, the data connection automatically turns backs on while it is sleeping. For example, when I go to sleep I press the red hang up button to put it in sleep mode then I go to sleep. When I wake up in the morning the data connection is on and when I go to turn it off it shows it has been connected for however long I was asleep for.
Like I said I am not sure if this is a big deal or not, I just don't want to be charged for going over the data cap for some reason. And I am not sure if maybe there is a program in the background that might not be showing up in the task manager and is downloading data that will eventually cost me when it goes over the cap.
Now I know that certain things automatically connect to download data like mail, weather, stocks, twitter, etc., but I always thought that they could use a wifi connection if available. And if not then I know for sure that it used to at least disconnect the data connection after it was done.
I am basically asking if this is normal because it used to not be like this on my phone and if it is something I need to.be worried about? Also, if anyone knows how to change it back to the way it used to be? I would greatly appreciate it if you let me know how to do it.
Thanks,
Michael
Anyone?
All I want to know is if it is normal to always have the data connection on. So does anyone else experience this? The data connection seems to reconnect by itself everytime the phone goes in standby and stays connected until I manually disconnect it.
Thanks,
Michael
Hey I just happen to have similar problem with the data connection turning on by itself when I check email on my wifi.
If you goto comm manager - menu - connections - advanced
Under "select which networks are automatically" - select networks
Change the connection type under "programs that automatically connect to the internet..." to your wifi connection from "t-mobile data."
Seems to work for me at the moment anyways. It's not connecting automatically to data connection when I check my emails.
Hi Michael.
It's actually the default behavior for the data connection to stay on once it's activated, until it's switched off manually. You won't pass significantly more data that way than if you just turned it off right after whatever app(s) are doing using it...the only downside to leaving it on is the speed at which it drains the battery.
There are some users who choose to leave it on, just to avoid the delay when they want to use it, and there's probably tons more who don't even have any idea you might want to turn it off when not in use.
Now I could swear there's a cab floating around here somewhere that will shut off the data connection once it sits idle for 60 seconds, but I didn't turn it up in a casual search the other day, so I can't point you to it right now
As for the apps using wifi when it's available instead of calling up a data connection, every one you mentioned should do that, and those all behave that way for me...so maybe there's something else you haven't thought of yet that ignores wifi when it connects to update or whatever. I would start by turning off auto updating for any and all of those services you listed, and see if the issue persists. If so, you'll need to dig deeper to find the culprit. Do you have microsoft myphone connecting to backup maybe? That seems to ignore wifi on my phone, I'm sure there's other apps that do as well.
Today it actually quit doing it for some reason. So I have no idea why it did that for awhile. Now I read that some people were having the opposite problem, which was that they couldn't get their connection to stay on. Now, this is actually the way I want it. Oh well, I hope it stays this way now.
Thanks for your help,
Michael

Losing data connection

I'm on T mobile with a dhd and my phone keeps losing the data connection.
I have to reboot to initialise it again. If I switch to wifi thats fine, but 3G data keeps dropping out. It can't be the network as the reboot seems to sort it. Sim works fine in other phones. Have you got this problem too?
I'm also getting the reboot problem and the dialer crashes too everyday preventing me from making a call. Otherwise a really good phone!
yep, I am having the same problem on my sim, wierd, I had never had this problem. It started today when i turned my data connection (mobile internet connection) on and did not turn it off, usually I turn mobile network (for internet ) on and then off after some use.
I will try to do same for 2-3 days, lets see what happens. Anybody else having same problem. any solutions ?

losing connection

Ive experienced that my nexus 4 sometimes loses data connection in certain areas, which my old iphone never did there. I can still call but data connection is lost. This doesnt happen with wifi. I then have to go to the APN settings, push on my provider's APN again, even though its already selected, and then it usually starts working again.
Has anyone else experienced this? Im not sure now if i should RMA this device or if its just an android bug.

[Q] Keep losing WiFi connectivity

I have an SGH-I337 that is running Cyanogenmod 11-20151112-SNAPSHOT-M12-jflte with baseband I337UCUAMDB, and I am experiencing some odd WiFi behavior.
The WiFi will be connected, showing in both the notification bar and the WiFi settings, the notification bar with show traffic (blinking up and down arrows), and yet apps won't be able to access the network. I can restart the WiFi via settings and this will usually restore app connectivity, though not permanently; eventually apps will lose connectivity again. Rinse; repeat.
At times I'll get annoyed at having the WiFi problems and turn WiFi off and use LTE. However, the WiFi eventually turns itself back on, often times exhibiting the connectivity issue that drove me to switch to LTE.
Another issue is that the WiFi will forget the settings for a given network. The WiFi app will simply show the network, not indicating that settings are saved, and I'll have to enter them again.
I haven't been able to establish a pattern to these issues, and it's driving me mad! Has anyone seen anything like this? Have any suggestions, besides taking a handgun to the phone?

Wifi and 4G stuck together - how to fix this?

I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?
