WIFI and GPRS

Can anyone tell me how this works on the wings.
When using Fring you can actually tell it to conect via wifi etc. but what i want to know is does mesenger do it as well or does it go straight to the gprs. Also when you go online via IE. does it default to the GPRS. I dont see anything that says to use the WIFI conection first and it looks like messenger and IE use the GPRS instead even though i have wifi enabled or am i wrong here.
Thanks ahead

By default, all aplications (IE Mobile, Messaging...) use GPRS, 3G (or other cellular network). If WiFi is on and available, all aplications are using WiFi instead of GPRS. (Only Fring has a bit different connection handling)

What Moneytoo said, only sometimes when I enable WiFi on the phone it wont turn off the data connection so I usually do that manually in the connection manager.

When you are discussing the process of connecting to gprs, I will add one question. Is there a posibillity to initiate 3G/GPRS connection without any app? E.G.: When I want to initiate a connection, I have to use some app which initiates it itself. But there are some, which can't handle this - so I have to for example check my e-mail first (altough I don't need it at the moment) and then the connection stays on and I can use second app. The button in conn manager for data connection is disabled, so I can't use it.

ok
OK thats good to know as i always have the wifi on at home. Just wasnt sure if messenger and IE use it or not as to be honust i dont see any diff. in load speed etc. I would have thought it would work faster via wifi the say gprs.

Very true, but I notice (and speculate) that you only cannot select enable or disable the Data connection unless you change or add another connection, or the phone is using it. If I wake up in the morning my phone is using data since I have the HTC home screen with its weather application, hit comm mngr and data is grayed out, but once the phone wakes up or I select Wifi and it starts working again the option to disable data comes up.
For me I just load or refresh the weather page and my data is connected, its set to always be on and since my plan is unlimited I dont worry about it.

Depends on what you are loading honestly, a page that your mobile browser has to read, compress resize and modefy to display properly will take time to load while it does all of this regardless of how fast your connection is. Could also depend on what others are using your connection for and if your on the B or G standard. Overall I notice a fairly good increase from using Wifi but I am only on Edge here which caps at about 20kb/s where 3g can get into several Mbits/s

Wifi setup?

Whenever I turn WiFi on, the phone will go nuts looking for access points (and chew up the battery doing so and notify me repeatedly). Is there any way to configure WiFi so that it will only using WiFi when it sees a particular access point(s), e.g. my home or work, and ignore everything else on the street. And when those specific access points are unavailable, go back to Edge, GPRS, etc.?

You can still turn off notifications if you want, go to Settings > Wi-Fi > Menu > Advanced and untick "Turn on available network notification".

After I've done the initial setup, when I enable Wifi, my phone auto connects to my Home Wifi and doesn't notify me of any other networks when I'm in Range.

yes +1, but I was thiking that anyway WiFi turns off when you shut down the screen, so when you walk in the street your wifi should not be alive. As to do so, you would have anyway a poor battery life. It's cool to use wifi when you need, but let it scan for networks all the time is not the best way.

Toggle between WiFi and mobile data with tasker

Hello. Does anyone knows how to make a script for tasker which switch mobile data off if WiFi is connected and mobile data back on if there's no WiFi connection? For the last 3 or 4 hours I'm searching for this and can't find nothing.
Also, I want if there's no WiFi network, to switch WiFi off (so mobile data will be turned on).
I managed to do something, but it didn't worked. When I enabled the profiles with WiFi and mobile data both turned on, the mobile data turned off, then WiFi off, then mobile data on and so on, in a loop.

Wouldn't that be redundant? The os already does that.

Thanks for the response. I know that if WiFi is connected, I'm using the internet from it, but mobile data is still active, right? Even if there's no traffic from mobile data, that's still on. Wouldn't that be a source of battery drain?

I set my data to turn off if my phone is connected for 5 minutes to a wifi. Important: set collision handling to 'abort existing task'.
Here you got pictures.
Edit:
if you are further interested in battery savings, you can read my thread "[BATTERY LIFE] How to get up to 7+h of screen-on-time"

This is absolutely redundant and unnecesary, when the phone connects to a wifi, it disables 3g/LTE data connection by itself. When you connect to a wifi you can see how the 3g/H/H+ icon above radio signal dissapears. The radio chip inside this phones can be used in Wifi mode or 3g/4g mode for data connection, but not both at a time. It is technically not possible.

The moment you don't have wifi anylonger, the phone starts a fullburst search for wifi and 3G/4G networks (even if I don't want wifi/data at the moment). and this drains a hell of a lot of battery. then (if you go out e.g.) it finds a 3g/4g-connection which it tries to keep up (drains a lot battery) and in the same time searches for wifi-networks (also drains battery)... very inefficient use of battery
So I deactivate data after 5 mins automatically via tasker and turn it on manually when I need it (could also automate that, but I'm lazy). This way I circumvent all these battery drains
Additionally:
Under normal circumstances I'd also set wifi to "turn off if not connected" (in settings) and "optimize wifi for battery life", but I use a custom stock kernel that has issues with these settings so I need to leave wifi on all day

Umm, ok... But this has nothing to do with what the OP asked, or what I said.

You may try e-robot from play store.
I have a command for that, after wifi disconnects, wait for 30 sec. If still wifi is not connected, automaticcaly disables wifi.
Same as for bluetooth. When i leave my phone in my desk and gone for a while, 60 sec later disable bt.
You can do what ever you want.

Cellular data being used instead of WIFI - ! shown with wifi icon

Can be connected to wifi, but for some reason the phone thinks the wifi connection is bad/poor, and then it will use cellular data (there will be an ! in the wifi)
This is VERY VERY VERY VERY VERY bad for me because I use a LIMITED CELLULAR DATA plan - and this phone decides on its own to not use what is really usable wifi. I have only had the phone 2 days and it is doing it repeatedly - did it at a hotel (which required username/password) but then every single time I leave the hotel and return, it connects to the wifi, but uses cellular data. If I turn off cellular data [I use Power Toggles app to make it easy], the wifi suddenly becomes acceptable to lollipop and the exclamation mark disappears from the wifi icon and I have internet access (no sign in required as the network remembers my mac id/authorized me for at least 24 hours) - and then I can toggle cellular data back on and it will stay on wifi - UNTIL I leave and return again when it starts all over again.
Similarly, at my home where I have strong wifi - sometimes it just decides not to use it. So, when I look at my phone and see the wifi with ! I have to do the same thing - disable cell data to get it to use the wifi.
This is ridiculous!
This switchover to cell data should at minimum be a user-configurable option. I do not want it doing this!

Already was disabled. (That was the option I chose when I set the phone up).

Auto Turn Off Mobile Data When Connected to WiFi

Does anyone know of an app that will automatically turn off mobile data when i'm successfully connected to a WiFi connection have have internet access through it.
The app should do something like this...
1. Check for WiFi connection
2. If WiFi = connected, then test WiFi connection
3. If connection = Good, then turn off Mobile Data, else leave Data connection ON
If you suggest Tasker, then you better follow it up with a full write-up on how to set it up on Tasker.

I believe (someone will correct me if I'm wrong) that Android is programmed to use wifi when it's available, even though your data connection looks as if it's on.
If you're not happy with that, Automate It should be able to do something for you. I have Automate It Pro set to turn off wifi & data at midnight, for example, to avoid the nuisance of emails pinging me in the middle of the night. And it switches wifi & sync on at 09:00 each day. Very useful tool, simpler than Tasker, so no tutorial from me...
There are a few Automate apps in the Play Store - it's this one:
https://play.google.com/store/apps/details?id=AutomateIt.mainPackage
This free version allows you 3 (as I recall) triggers - if you need more it's not too expensive to buy Pro.

I use RadioControl to handle that for me.
https://play.google.com/store/apps/details?id=com.nikhilparanjape.radiocontrol&hl=en
It requires root, and it's not perfect. But it works well enough for me.

Try smart radio xposed module.

Tasker does it pretty simply, but it needs root access..
Set up (2) tasks - I called mine Data Off & Data On. You will need to select "Net/Mobile Data" and then set "On" or "Off" respectively. Next set up your profile. Select "State/Net/Wifi Connected", and leave everything empty and save. This will trigger the profile when any wifi is connected. (Optionally, you could set it to your home or work wifi, etc). Your "task" will be "Data Off", then add an "exit task" for "Data On" (by long pressing the Data On and selecting "exit task").

^^^^ This. Android has done this for years. Some devices have the ability to keep mobile data on with wifi, but those usually default to OFF.
Note in the screenshot below that my Cellular network state (mobile data) is "Disconnected"

Interestingly, I bring up the same screen on my phone (when connected to wifi) and it shows cellular is still connected??

Do you have a ROM that has that option and it is enabled?

Running SIX ROM - Just checked, that option is disabled in the Dev Settings / connected to good wifi / and cellular is active...

¯\_(ツ)_/¯
Now it is a question for that rom dev.
