General :: Mobile Data Connection Doesn't Work After Using WiFi?
Jul 15, 2012
I am using ICS Evervolv a5 on my N1. The mobile data connection works only if I don't connect to a WiFi network. If I do, the only way I have found to make it work again is to reboot the phone.
This means that while I am at home, everything works through WiFi, however, if I leave home, I have to reboot my phone once I am sure the phone is far enough from my WiFi access point to be able to connect. Then, it starts working with the cellular data plan
The only thing I can relate to this is that I have the "application protection" app installed, protecting the settings menu do with a code so my kids don't mess up with that. However, is still hard to believe that's the culprit.

I recently bought a Telstra HTC Wildfire and unlocked it by code to use my 3 SIM card on it. However, after unlocking my mobile, when I choose the option "use phone for data connection when wi-fi is unavailable" it doesn't work. When i go to mobile network and network operators, I select to search for networks and the phone is automatically connected to "3Telstra(3G)". They also show 3(3G) and 3 networks, but when I try to select any of them, it says that the SIM card does not allow the connection to this network. I don't know if one thing is connected to the other, but I always used my old phone for data connection with the same SIM card.

This is something I have wondered about Android OS/Hero/Sprint since day one of my purchase, but I have never brought it up here. When mobile network is off and WiFi is enabled, I cannot retrieve my Yahoo Mail. It has never really bothered me, because when mobile network is connected and WiFi is off, my mail app (which is connected to Yahoo - I don't use Gmail) worked perfectly fine. Does anybody else use Yahoo as their email server and has the same issue? Is it just Google sticking it to their customers and to Yahoo by saying "ok, if you wan't to use our (#1 competitor's) email service, then we will make it so it will only work on Mobile Networks.

I've recently updated my Samsung Galaxy S4 to android 4.4.2 kitkat. Since then I've been unable to connect to the internet through mobile data. It can be activated/deactivated, but when activated I cannot connect to any websites.

You can use the 3G network for surfing the Internet and at the same time the wifi network to move files only?

Facebook app will not work over mobile data on my GS3. It works fine over WiFi, but on mobile data its slow. I flashed the 4.1.2 leak i wonder if that has anything to do with it.

I do know that downloading on Wi-Fi is faster than using data (or so I've read). My question is if I start a download using data connection then turn Wi-Fi on will the download see the Wi-Fi and jump on that to speed up our do I have to start on Wi-Fi for it to use Wi-Fi?

I run into rather strange problem. My phone, china Android 2.3.4, is working quite weel instead of this:
If I use WIFI, then turn it off and try to use mobile data connection, it is not possible.
Icon showing that mobile connection should be active is on, but no data comming through.
I tried switchiing to airplane mode, changing access point names and so on, but nothing worked. Only solution was to restart the phone, after that all works normally - until connecting to wifi.
After rooting my phone I tried to figure out more with Teminal emulator. It seems that after releasing wifi connection and turning interface down, mobile interface comes up with same IP as before - it should ask network for new one. But, more important, route table is empty (or containing one entery and no default gateway at all) I tried bringing mobile interface up and down several times, tried forcing it to use dhcp (timeout), without success.
Is there a way to "reset" whole networking system from shell? Something like partial restart, which would be probably quicker than full restart.

Will be going on a trip soon and roaming is expensive so data will be off most of the time. I'm thinking of using location history to keep a record of the trip route.
Does location history works without internet access? Will it store the location and sync when theres internet access or flat out don't work at all?

The facebook messenger app for my Samsung Galaxy Fame only receives notifications of messages when connected to a mobile data network, not when connected to wifi. If I swap to solely using mobile data after a conversation, I receive a string of notifications of all the messages I've just been sent in the conversation which is very frustrating.

when both wifi and mobile data are available, android (from version 4 and onwards) is smart enough to always* use the wifi, right?
*: by always i mean with some exceptions like sending an mms.

Current version of Android (4.2.2).
Want to: run apps that demand to have WiFi on+connected, even when I'm on 3G/4G. (Specifically, I'd be happy if I could get Xfinity TV Player to run on my rooted stock Nexus 4 over HSPA, but again, hoping this thread will attract info about tricking apps in the general case.)
Tried:
A) qaWifiOnlyMode.txt,
B) running WiFi Tether For Root Users and quickly turning wifi on after launching. Neither worked.

I've had an HTC Desire on Orange in the UK for about 6 weeks and it is having persistent problem. Firstly despite having a strong 4-bar out of 4 signal, online services and the internet do not work at all when a 3G signal is being received (e.g. news, weather, all widgets, internet, email etc).Calls and texts do work however with a 3G signal.But when a 3g+ signal (HSDPA) is being received, all internet services as above work fine.However, when a 3+ signal is being received, the phone does not make or receive calls or text messages, and often fails to send texts. Calls I make immediately shut down (bleep + �call ended�), and incoming calls from other people go straight to answerphone. Also often when turning the data connection on/off, it freezes and has to be rebooted, and turning airplane setting on and off does not fix the problem.
I have also tried the different network settings (GSM, WCDMA, auto, etc). �GSM� sends and receives calls and texts but doesn�t work (or is incredibly slow) with internet, and �auto� and �WCDMA only� show the problems as above.I don't think this is a network/coverage issues as, as I have seen many people reporting these same issues on other networks and in other parts of the UK, and I have read that other people are having to manually turn off HSDPA to be able to make calls (using an app?). Even if I can stop HSDPA from connecting to make sure the phone works, I still can�t use the internet at all on 3g � even GSM works better!
Finally, when I connect to a bluetooth device (e.g. car and headphones) the phone will connect briefly, and then randomly disconnect. I have also seen this issue reported elsewhere.I very much like the phone and don't want to get rid of it, but these problems are making the phone unuseable.Also I don't know if I should be contacting HTC or Orange about this. Will the upcoming Android 2.2 fix these problems?Anyone know how to fix this or if I need a new handset? Are there any apps that can help? Also does the Nexus One have these problems and are they fixed by Froyo?

How can I set my Galaxy Nexus to prefer WiFi for data over the Mobile Network? I have to go to settings, turn off "enable data access over mobile network," then cycle WiFi on-off several times before the phone will connect to my home router. Router has two channels, both a WPA2 encrypted one, and a "home guest" (open) one. Both show up as disabled until I cycle the WiFi off and on several times. There must be a setting to tell the phone to prefer WiFi -- no?

I recently bought a Huawei G700. It's a fairly new and uncommon device. It runs Android 4.2.1 in combination with Huawei's own Emotion UI
When I have WiFi enabled and for some reason my Wifi disconnects (for example I go out of reach), my phone keeps asking me, each and every time, if it's allowed to use Mobile Data. if I don't answer, my mobile data does not connect thus I can't recieve any mails etc which is highly annoying.
This is the exact error/popup message that I get:
Data connection change. WLAN is unavailable, try to connect to mobile network?
I've googled this exact phrase, but I get 0 results. How can I prevent my phone from asking if it's allowed to use mobile data?

Droid Incredible running 2.2 OTA. When watching live streaming content using NFL Mobile app over my wifi connection(which is Cox Cable), the feed loses its connection after exactly five minutes of streaming. At the five minute mark, the feed will freeze and the V-Cast loading icon will appear spinning, then an error message will appear saying that NFL Mobile could not establish a connection. Back out at any point during this and hit the button to play live content, live content will work again flawlessly for exactly five minutes. Then the feed will freeze, etc...There are no problems with live streaming content when I am using 3G. I have tried using several different routers at different settings and the problem occurs the same with all of them, and I have no problems with streaming content over wifi other than NFL Mobile. This problem also never occurred with the versions of NFL Mobile prior to the current 2.0 version. Anyone have any ideas on how to fix this? The app streams much better over wifi, but that's not worth having to restart it every five minutes. A big reason of mine for being with Verizon is the NFL Mobile app so if anyone knows anything please let me know.

Mobile phone. I bought it year and a half ago, and have changed operating systems few times (custom roms). Now I have Pristine JB Slim custom ROM, i have installed it 1-2 months ago (cant remember exactly), and everything was okay for first half period, but then it started to crush after mobile data/wifi was turned on.
When I turn on MD/WIFi, its usually okay till 76% of battery, but then screen starts to blink for few seconds and turns off immediately after. When I turn it on again, it turns off again after 1-2 minutes, and sometimes even warns me that i have to charge it cause battery has only few % left (most of time just 1). And I have to charge it again to work normally (well, until it starts to go crazy again )
Before i start to install other roms again. So. Is it faulty battery, bad ROM or something else?

I have been using raptor with a2sd set up, the newest kernel and turbo 4. I decided to install nfl mobile so I can watch the thursday night game tonight and it doesn't work.... thought it was an a2sd issue so I reformatted my sd card and flashed a fresh raptor. It worked. So I updated the kernel and it still worked. Then I isntalled the turbo4 and it no longer works... bummer. I'm figuring that the JIT is worth more to me than the nfl mobile app so I am going to leave it alone. I did find during this process that my phone seems quite a bit faster without a2sd. I have the original sd card which I'm sure makes a difference, but I think I would have to stockpile apps before a2sd would be faster than internal memory even with a faster card.

I never had a problem until today and now my evo is having trouble connecting in places it used to work great in. And when it does connect, it (a) either doesn't work at all (browser, speed test, nothing registers an internet connection) or (b) works for a minute, then (a) happens. I have an allegedly "good" 4g signal too. Tried soft reset and battery pulling, hoping that the problem will go away before resorting to a factory reset...

Currently using launcherpro as default but having a little problem with my data connection. Do you guys leave mobile internet on then use a data connection toggle like on switch pro to enable disable as and when you like? Or do you use a toggle like curvefish apn to rename and automatically connect to the network? Or do you turn it on and off via settings or the power button as and when you need it? Bit lost on the subject to be honest. Also when I go and turn mobile internet on in the settings under it it says something like connect to mobile internet when WiFi is unavailable. Is this the default setting or can it be changed to only connect when I want it to?

I purchased an Incredible, which I was not too happy with, so I decided to send it back and reactivate my Eris. My Eris was at 2.1v2 at the time. I called Verizon and had them do the switch through their customer service number.
Immediately I began to notice that I had a lack of 3G. My Turn Mobile On setting would be stuck on "Turning On". I could force it by switching airplane on and off and then using the power button to choose Mobile settings. Once I'd get it on, 3G would be spotty and drop in and out, and when I do have it it is ridiculously slow. Speed test shows downloads of 302 kbps and uploads of 1023 so it appears I have upload 3G but not download. Many times throughout the day I get data connection failures on apps requiring internet.
So, I called Verizon, we went through all their steps including escalation to tech support and they decide it is my Eris (which worked perfectly previously). They are sending me a replacement. In the interim, I went back to the Incredible. And immediately had the exact same problem on the Incredible. I called Verizon, and went through all their steps, and now they want to send me a new Incredible. I went back to the Eris, and upgraded to 2.1v3, still the same problem. I am 100% confident that when I get the replacement Eris it will solve nothing. APNs are at correct default.

While I was out today with "Mobile network" selected and an HSDPA connection I was able to update weather, view a Google Map, browse web pages and read GMail messages. However, when I replied to messages in the GMail app my replies were not sent. They sat in the GMail app with the word "Sending" shown in red in the Inbox. I tried toggling the mobile data connection off and on a couple of times, but still no joy. As soon as I returned home and reconnected through WiFi the messages were sent within a minute or so.Has anyone any suggestions as to what I might do differently next time?
