Hi all,
Mobile data (2G) is not getting connected properly in my new Samsung galaxy S3 (ICS). I use Tata Docomo.
As soon as I restart my phone I am able to connect to mobile data for sometime and then if I disconnect it or if it automatically disconnects then I am not able to connect to mobile data after that. The "E" symbol does not appear on notification bar. Its like just one time using of mobile data per restart of the phone. So I need to restart the phone if i want to connect again
Even after selecting "Use Packet Data" in settings, the status of "Mobile network state" is "Disconnected" under the Settings -> About device -> Status. But WiFi works without any problem.
I have installed the internet setting which was sent through message by Tata Docomo.
Please help me what could be the problem here.
I am feeling so sad for not being able to use internet properly in my new phone :'(
Please find the screenshot below,

Wong thread dude. Q&A
If you have stock and your packet data is on without use 2g networks only, they may have given you some wrong settings..
Failing that do a factory reset to see if that works

You would never get an answer here coz thats a known issue with Tata Docomo and not your handset. Tata Docomo at regular intervals disable your Cellular Data which they says is to ensure your data pack does not get depleted due to your leaving ur data on by mistake. Silly huh? More interesting it does not get automatically connected to the network
However i have found fix for it. Just select Network Type as Automatic(2G+3G). Wheneve data gets disconnected, If your using 2G, select 3g Network of Docomo and then select 2G network of Docomo. And vice versa if your using 3G. It should start your data after 10-15 seconds of doing the above 2 steps.

Tablets powered with Android 4 supports a large number of 3G modems:
Huawei E156G
Huawei E173
Huawei E220
Huawei E1750
ZTE MF637U
These are modems that are tested. Other modems might work as well.
To setup your modem follow the instructions below:
Go to settings (press the status bar in the low right corner) and press <More...> and you will see the following:

}
Select <Mobile networks> and you will get this screen:
Select <Access Point Names>. when you come to the Access Point Page you click in the top right corner and select <New APN>.
This is the tricky part where you fill in the GSM operators settings. You can find settings for the most popular networks here. If your operator is not included you will have to ask the operator. The screenshot below shows the settings for Safaricom, Kenya:
When all settings are filled in press the arrow in the lower left corner and you are done.

Care to elaborate a bit? I tried and did not have much success, did you? If so can you please post some pictures of it working?

Sorry 2all
Sorry to all this will not work. I take that manual from other site. It say Andtoid 4 3G Setup (original link in #1 post). I test it my self. No success.
Than i unpakced firmware to find out files like (gprs, pppd-ril.options, usb_wwan.ko, etc), some of them presents in firmware, others dissmised.
So the only way getting 3G via dongle, is custom firmware.

Well if u have to use 3g/data connection outside wifi range just use your cellphone as a wifi hotspot. Most people carry a cell and most of todays phones can do this

thanks, i know how to go to web via phone by changing wpa_suplicant2 file. But i want to connect via dongle.
I dont know how real this is, I have rooted my TF201 and no where do I see the mobile network on a stock rom, I have it on my phone yet I dont have it here, and also there would have to be drivers for the USB modem to be entered, this isnt a simple task, the only one i have found is in the UMTS app from the market, and even then this doesnt work, I just want a USB modem installed, I dont want to use my phone as the WIFI defeats the purpose of having a USB modem, surely someone has done this on a stock rom
I did a reboot/factory restore on my wireless router couple of days ago and ever since that my phone barely connects to my home wireless network. It keeps saying Network out of range even though I'm right next to the router. Finally after 20+ minutes of waiting, it finds it.
I tried "forget network" and add it back but it's still happening. I got the 'Fix my WiFi" app and no luck. I also tried rebooting. Haven't tried factory reset but I may if this keeps happening.
Is there something wrong with my router settings maybe? My laptop connects fine though.
I think there might be something wrong in this settings for the router.

I had a problem where my WiFi didn't work and had to flash all the away back to 2 variations of stock via Odin. I'm not sure what went wrong, but it probably isn't a problem with your hardware.

Did you wipe Davlik (sp) cache in recovery to see if it fixes the problem?
did you try changing the wireless channel on the router?
Turn on broadcast ssid.

Miz Z2 MTK6589 Quad core 1.2Ghz CPU Android Phone 5.0 inch Screen(1280*720 HD IPS) 1GB RAM 8GB ROM 12MP Camera
Since I bought this new MIZ Z2, I am not able to connecto any wifi signal
I have to say phone is great except the wifi problem it is causing me too much trouble.
WIFI shows connected, wifi bars signal remains 'gray color'. not 'blue bars'. so I can not connect to internet through my wifi, although it shows it is connected. but i am not able to.
I have tried resetting the phone, restarting the phone and router, but no use. tried on four different wifi spots(my college, my friend's house), at no place it ever connected to WIFI. Infact it shows "IPv4 address: unavailable". it is running Android 4.2.2, there is no option for ''Static IP address" or IPv6 address. some time it shows message : "navbar err x 01" and then I found somewhere about the replacing WiFI and CUSTOM WIFI files in data/navram folder. I restarted the phone after replacing files, but still no luck
I have tried searching the internet, and tried various tricks mentioned there, but none of them worked.
I have done the following.
1) Turning ON OFF phone and router-- no good
2) resetting the phone to factory settings --no good
3) clearing the cache in apps >> google service framework >> clear cache >> stop >> and restarting the phone --- no good
4)changing the broadcasting channel at my router, disabling wpa keys and tried to connect to open wifi networks-----no good
5) replacing WIFI and CUSTOM WIFI files
So far, I have found no solution. can anyone out there guide me in right direction..
Many thanks in advance

turn on your data connection, set your APN and restart!
I got it working finally.
Below is what worked for me, it may or may not work for others having same issue:
1) Settings >> Sim Management >>> Data Connection ::: select your favorite sim having activated data plan.
2) no go back to Settings menu again and tap on 'More'>> Mobile Networks...Make sure Data Connection is ON. select 3G service on with your favorite sim.
3) Go to Access Point Names. Select your sim with data plan, Tap on it and it ll open new screen and now tap on the left side of menu button on your phone and click "New APN" .
4) here pls enter the details such APN name(anything), APN, username and password (if you dnt know these three i.e. APN, username and password, you may have to ask you mobile network provider)
5)press the square buttons again and tap "save" and exit the setting menu
now go back all the way and try to connect WIFI again. It still did not work for me so, At this point I restarted my phone and when my phone was turned back on WIFI bars were blue and I was able to log into playstore.
[optional]: I turned off my data connection after wifi was fixed and since then wifi did not drop a connection nor shown anymore "gray signal bars"
So internet is working fine now
PS: please do note that I did replace my WIFI and CUSTOM WIFI files earlier, but it did not make any difference at that time. So not sure, this made any difference or not. but try above at your own risk!
Question is as exactly as it is in the title; how does Android come to the conclusion that it has complete internet connectivity (or connection to google services), and consequently will turn the signal bars blue (on stock android devices).
I am trying to fix a problem at work where if I put my phone on the company wifi, my phone never seems to think it has internet connectivity, even though I do. The consequence is most apps don't attempt to pull new data, and therefor never notify me of new messages. This includes gmail, google voice, and hangouts.
I don't have direct control of the network infrastructure at the moment, so right now it is easier to know what address or IP it tries to get to, and how (ping?), so it can be unblocked by the firewall or web filter.

Does really no one know? Perhaps a point in the right direction?

check your settings>wireless & Networks> WIFI>check Network notification this will inform you when there are other open wifi networks present > you need to connect to that network with password or scroll down to add WIFI network (you can add any network when you know its SSID and security used.
if you unchecked network notifications, you will " NOT" know or use of any new networks other than what you have used before.

I'm not having any issues finding or connecting to wifi, the problem is at my buisness when on wifi, android does not detect an internet connection; so it thinks I just have local network access, so most apps do not auto refresh in the background.
Hello Everybody,
today I tried to use scrcpy to remote control my Pixel 6 (Android 12, Build Number SP2A.220405.004) via USB.
USB Debugging has been activated.
However, as soon as I establish a connection from scrcpy to my phone, the cellular data symbol switches to this

As soon as I disconnect the usb cable it will have a data connection again.
Does anybody have an idea where this could come from?
Did I miss some settings?
Thanks in advance

Im not familiar with the phone, but there are some settings that could be causing the issue. Here are a few:
In 'developer options', the switch 'Verify Apps over USB' could prevent the program from running...switch that to 'off'. Check Google Play Protect, turn off to test. Those may not be allowing the 'scrcpy' to function.
Also, the phone may think its in a wifi network, so it kills the data connection. In 'dev options' there should be a switch called 'Mobile data always active', when wifi is active, turn that on.
In Settings, under 'Hotspot & Tethering', there is a switch 'USB Tethering' ->share phone's internet connection via USB ->set to on.
In 'Wi-Fi Preferences', the switch 'Auto switch to mobile data', set to on.
Test also the 'Tethering hardware acceleration' option in 'dev options', it may be interfering with the program.
It could just be a tethering issue.
On a final note, if you have root or command line access, you can set the local routing tables to function with wifi & data like this:
1. "ip rule" //shows routing tables
2. "ip rule add from all lookup main pref 1" //adds table as 2nd in line.
The latter rule allows data & wifi to function in same routing network. May or may not be necessary to resolve your issue.
Wow - I didn't expect a reply that fast
I'll check the settings later when I'm back at a PC and post my results. Thanks a lot @Xpltr
Simply disabling wifi solves the problem.
Thank you for all the tips, maybe I'll find some time in the future to check the other points and find the root cause.
