[Q] Auto switch between 3G to wifi mode

This is a feature I was trying to use with WM6 in the past but it wouldn't work. My question has to do with Android in general and with either Desire or Desire HD.
Let's say that I use a 3G data contract and sometimes I have wifi available as well (but not always in reach). I want to save my 3G data because I pay per kb and prefer to use wifi when available. Is it possible for Android to automatically connect to WiFi when it is in reach and when I move out of its reach, to revert to 3G?
If not, what is the way to handle this? for example, do I manually enable/disable one of the 2 and try which works?

I just turn both data and WiFi on and leave them on. That way as soon as I am in a WiFi zone like at home, it will automatically connect to WiFi.

So, to make this even more clear: you have them both turned on (3G and WiFi) and WiFi will take priority? and revert to 3G only when WiFi is unavailble?
and we are talking about which model? or maybe it'a all Andreoid the same?

I think its the same with all Android phones. If both 3g and WiFi are on WiFi will take priority. I am at work and have both turned on...as soon as I go home, the phone will connect via WiFi automatically.
By the way I have a desire too.

Thanks a lot. That means that desire will do for me. I don't know if that has been resolved with WM though, maybe it will be with WP7 but I think that Android will e a better option for now.

Hi, you can also save battery/money with softwares that automaticly close 3g/wifi for night. I use "data on demand" and "settings profile lite" to close both for night and also close wifi when my location is not home.

nice. are most of those software free for Android or you have to buy them? similar to WM?

Hi, both are free, just install through Android Market.

Mobile data turns on when wifi turns off?

I've noticed that whenever I turn off my wifi connection, the mobile data connection automatically turns itself on. This is quite annoying as I usually have it turned off to conserve battery.
Is there any way to disable this?
Thanks in advance.

No as the Desire is a smart phone which always needs a connection to the Internet to update - it's working as designed

Well if the user specifically wants to turns off the APN connection and keep it off until manually turned on, I don't see why that's such a big ask. I only want to have control of my phone, not the other way around.

I use Honolulu Team's Extended Controls to switch both wi-fi and mobile data off when not required.

I also use this, but if I have wifi turned on for example (with mobile data turned off prior), when I turn off the wifi the mobile data immediately activates without my say so.
There must be some way to disable this automatic connecting.

Changing to WiFi only Data?

When I installed my ROM, and on first boot I was given an option for when to use data.
Wifi only, or WiFi and Mobile Networks.
Now, I am going on holiday in a week and wanted to switch it to WiFi only to avoid data roaming charges.
Can anyone help, I cannot find it in the settings.

Settings > wireless and networks > mobile network.

Obviously I looked there first. There doesn't seem to be a "WiFi Only" option.
If I just deselect Data Roaming, will that essentially do what I want?

Yes, just turn off mobile network and turn on WiFi.

In the widgets > settings widgets you can choose mobile network and wifi network (as well as gps and bluetooth) screen widgets so you can toggle them on and off.... when not wanting to use mobile data, its good to have those widgets on one of your screens (as the dashboard widgets are usually missing one or another of those 4 essentials)
saves time from going into the settings repeatedly just to turn something on or off.

If I turn of mobile network, wont I be unable to make calls or receive texts?

It is stated in the setting that it enable/disable data packet usage over mobile network. It has absolutely nothing to do with your phone call whatsoever. What makes you think that way?
Just kidding. In extreme cases, to prevent data on moblie network, one uses firewall to block access to any applications that try to access it.

All you need to do is deselect Mobile Network. Even the description says its used to connect to the internet.

a question really easy

[SOLVED] WiFi not working properly? 3G/4G stays on due "My Account" App

So when i am home i have my WiFi on, which means my 4g is off. Now when the WiFi is on, i can not receive or send pictures. Also cant use the web or do anything like that but just send and receive text/calls.. and reason to this? maybe i have certain settings on that i don't know about? If i remember right, my wifi worked properly a few days ago.. but i cant remember exaclty. Help please? Thanks

no one knows?

Power cycle your router?

I've been having a different wifi issue. at home I have only edge coverage but I have petty good cable internet so obviously I want to use my wifi but for some reason the phone connects to wifi yet still uses the mobile network unless I turn off mobile data. My wifi sleep policy is set to never btw. Any ideas?

Also if I turn off mobile data while connected to wifi then turn it on while still connected it stays on wifi fine. Its like the mobile radio is preventing the wifi connection from fully initializing or something

Same issue!

I am having the same issue. I have to go into airplane mode, then turn on wifi to actually be able to use it... otherwise seems to default to mobile radio...

I have the same issue..this is what i do to work around it though:
1. Go to Settings>Wireless and Networks>Mobile Networks
2. Uncheck packet data, and then check it again.
Once i do this, my wifi works again, let me know if it works for you.

yes, does seem to work, but agree it's frustrating.... Hope they fix this soon.

Got this from the battery thread. This actually fixes the wifi issue on my SG2
The program is called Llama and can be downloaded from the market. I deleted all the default events and just added these 2. Hope this helps for all of you with this issue.

-- Add condition: WiFi Connected (any network)
-- Add action: WiFi Sleep Policy (never sleep)
-- Add action: Toggle Mobile Data (off)
- Add another event called WiFi Disconnected
-- Add condition: WiFi Disconnected (any network)
-- Add action: WiFi Sleep Policy (sleeps when screen turns off)
-- Add action: Toggle Mobile Data (on)

Try freezing "my account". It toggles data even with WiFi is on. Try it and let me know.

Actually saw this tread and had Llama installed with these 2 profiles added and was till getting this issue... Going to try Freezing My Account to see if that helps... I know it helped with my wifi issues on my G2x.
Update: Nothing seems to work now. Can't have Wifi and cell radio on at the same time... can get calls but nothing else...

I've seen it occasionally as well. I haven't needed to reboot though. It usually recovers after I toggle WiFi on and off and mess with some other things.

I notice the same issue and I also toggle wifi on and off to get it to work back again.

Same here. I have to toggle wifi on/off and sometimes reconnect through wifi settings to get it back.

Yes, either return or warranty exchange for a new one, I have not noticed this issue with my device at all.

I've been having the same issue and it definitely causes excessive battery drain. Sometimes toggling wifi off then on works. Other times it requires toggling mobile data off then on.
I had it happen just now and tried freezing 'my account' in titanium backup as suggested and my 4g indicator immediately turned off. Sweet! It seems that 'my account' is the culprit!
Edit: I really wish this topic wasn't merged...I think there were a couple 'wifi problem' threads talking about different issues. To clarify, my problem was that while on wifi my 4G indicator would sometimes turn on and consume more battery and (sometimes) force all data to use 4G instead of wifi. Really annoying!

Try Wifi Toggle that works the best, as soon as you out of WIFI network i mean range it will turn off and when back in Range will turn on.

Automateit can do the job of turning on wifi when starting a specific app and turning it off when deactivating the app.
