Defaulting to 3g connection even with wifi connected - Galaxy S II Q&A, Help & Troubleshooting

I was wondering if anyone might know how to fix this. The problem seems to be that when I am connected to the carrier's network (AT&T) and have wifi on at the same time it still just uses the cell connection. I have an app that I have set to only download data via wifi (dogcatcher) and if I have both connected it won't download anything because it doesn't see itself connected to the wifi, but if I go into airplane mode and turn wifi on it works just fine.

[Q] strange wifi problem

I am on bionix 1.3.1 and have noticed that whenever I turn my wifi on it seems to not allow me data access. My web browser will not connect to a page, market won't load, and any downloads that were in progress will fail. it's as if turning on the wifi is overriding my data connection and blocking it. It says that it's connected in the menu though. Any advice?
Thanks
Edit: I just noticed when looking at my phone stats, that when I turn on my wifi my mobile network state says disconnected, and it connects again when wifi is turned off.
Also, I have an airport extreme and a mac, perhaps that is my problem. I've scoured the internet and found a bunch of info about this problem, but haven't found anything that works yet.

Im sure someone will correct me if Im wrong but if you switch from wifi to 3g while downloading the download usually will fail because you were using only wifi to download the content and when that turned off it doesn't just switch to using 3g you have to manually retry the download using 3g .... when wifi and 3g are on wifi doesn't speed up the 3g instead it does the internet related work and the 3g does the text and phone call related work
that makes sense, thanks. as for the connection problem, it is definitely mac related. my wifi seems to work on other networks. I just need to figure out how to make it work with the airport. It's just weird to me that it says it's connected and shows signal bars, but won't access the internet.

so is the new problem that the airport extreme won't give wifi to your phone or that its not working at all
According to my phone I am connected via wifi to my network from the airport, however, the phone cannot access any internet functions when connected. When I disable wifi, it works fine with 3g or edge. It seems to be something with the settings on my airport, not the phone itself.

That's surprising maybe this means apple products are biased

loooool! I dont think there is a set up as much mate. You set up ur wifi and ur mobile network settings. When ur by wifi like home it connect then when u leave and go out it connects to the mobile internet. Thats how mine works.
looks like an iphone but powered by android baby!!!!
just connect it mate, then automatically the phone will turn the 3g network off (when connected with wifi)

What it means?
Thanks to all for the answers, so I have to do nothing because I have configured my 3g and wifi, so my phone should change the connection depends of the situation.
Thanks!

[Q] WiFi Connection Problems

Anyone with the Amaze 4G for T-Mobile USA notice that it often doesn't connect to remembered WiFi networks even though they are in range and it will only connect if you go to view WiFi settings/networks under settings then it connects?
Also, anyone have any issues connecting to WiFi networks where the SSID is not being broadcast? I can get it to connect initially but it will never reconnect to a hidden SSID network that it "remembers"?
Using stock gingerbread ROM.
I notice this happens every now and then... I will have to open my WiFi networks, then before I can click on the network, it refreshes. It happens only rarely for me, but I have noticed it at times

Re: Wifi and 3G Problems

Re: Wifi and 3G Problems
This issue is about to drive me up a freaking wall.
When I'm connected to Wifi at my house and I leave and get out of wifi range my phone doesn't connect to mobile network. I have to reboot it every single time to connect to 3g.
I've called Sprint several times about this and they just walk me through the process check.
Is anybody else having this problem? If so do you know of a fix? Thanks

Mome connects after a minute at the most. Try putting into airplane mode and back. Also just for fun try updating prl

I'm having the same problem. Leave the house and phone still shows I'm connected to the WiFi. I turn WiFi off and get the 3G symbol, but apps are report that there is no data connection. Need to reboot to get 3G to work. Toggling Airplane mode doesn't fix connection.

AllShare Cast Dongle Wi-Fi issues

Searched but can't seem to find a solution so hopefully someone can help me out.
Had no problems using the dongle up until I updated to Jelly Bean. Now I can only connect if I have a Wi-Fi connection or no internet connection whereas before it was fine with just mobile data and this is what I prefer. When I connect with just mobile data it turns my Wi-Fi on and switches automatically, I tried 'forgetting' my Wi-Fi connection but then it shuts down as soon as it connects! This is driving me mad!
