Can you run Wifi and 3G/HSDPA connections simultaneously?

So the if the phone connects over wifi it drops the data connection that might've been present on your phone network connection. Is it possible to configure your phone to maintain both wifi and 3G/HSDPA connections at the same time?
I require this because my operator provided (H3G UK network) Skype application only runs on 3G and I have to keep turning off wifi for it to work.

Funny, I find this feature great!! With my WM phones I never knew if it was using wifi or my data connection....even if you can do this how do you make one app use one connection over the other?

Good q, i'd also like to know if it's possible...

You can try droid wall, and configure it to block wifi for skype, it may solve your issue.

Hmm, doesn't sound like that will work, because the phone has already dropped the phone network data connection as soon as I get back home onto my home wifi network (due to prioritisation?) I want the phone to maintain both so I can receive incoming Skype calls at home with fiddling with my phone. I understand why the phone does it and it is sensible for it to do so in most cases, but just not for my usage requirements!
Is it a software/hardware limitation that wifi and phone network data connections can't be open at the same time?

Install Nimbuzz. It supports Skype without that bulls**t restriction. It doesn't support group chats though.

if WiFi is on, and 3G is on
the phone automatically uses WiFi first

I lose the "H" or "3G" notifier when the phone connects to wifi, that's why it looks like it's purposesly dropping the data connection once it picks up my wifi, I can't see a way to maintain both simultaneously.
I'm using "Skype for 3" provided by my network, it has special integration on the 3 network which allows me unlimited Skype usage (inbound and outbound) without it eating into my data plan. So with this benefit I don't really want to use an alternative app.
I want to keep Skype running all the time so I can receive calls on it, but once I get home, the wifi kills the "H"/"3G" connection, which means my Skype can't receive calls.

the icon isn't there but i think the data (H / 3G) is still running in the background, incase your Wifi fails.
wifi is the... PREFERRED network?
have you tried getting your friend to call you via skype while you're on wifi?

Wifi Connection Drops

Hello all,
I use a campus-wide wifi network (MAC registered, since the WPA2 Enterprise network requires the phone to keep inputting my password for credentials) while I'm at school, and sometimes the wifi network will drop and not reconnect.
For example, after a random period of standby time, when I turn on the phone and look at it, the wifi will still be happily connected with a proper DHCP-requested IP address, but all efforts at using ping or the Internet browser and so on will time-out.
As far as I can tell, calling reassociate() on the connection is not very effective, as I've tried applications that monitor the connection and try to reassociate().
The problem most often occurs when I leave campus and then come back on.
If I cycle wifi on and off, then the wireless will work again. However, this is annoying since sometimes push Gmail will not get sent in on time. This is also problematic for Voice, since that requires data, and if the phone thinks wifi works, it will not bother connecting to 3G/data to get Voice messages.
Any thoughts? Log-looking suggestions? I'm open to anything! Does anyone have this problem too? (I think my personal wifi router drops similarly so.)
InfX and I looked at the sleep states of the wifi and CPU performance in thread http://forum.xda-developers.com/showthread.php?t=950655 , but that seemed inconclusive (although it is slimly possible I am not building the kernel correctly).
Thanks muchly,
Jeff
Edit: I am using rafpigna's kernel on a Sense (imilka's mytouch 4g) build.

will android switch to a better wifi if available?

Heyho, i currently have access to my wifi as well as to my neighbors network as my wifi gets weak while i am in the garden. I feel like android isnt awitching to my neighbors wifi automatically. Only when my wifi is completely gone, android will look for a new one.
I thought about making a task with tasker which looks for another wifi as soon as the current wifi strength goes below 25%.
Or is/should android do that aleady on its own?
Thanks

In wifi -> Advanced settings there's an option to avoid poor connection. I have no idea what it actually does, but give it a try.

I did the test with my router, which supports 2 frequencies.
Assuming both networks are saved in the phone, it connect automatically to the one with better signal or look for an alternative if signal is lost.

Thats what I mean, it will connect to the other WiFi if the connection is lost. But if the connection is crippled (bad) enough to not handle a music stream, but still "availabe" it will not switch to the other WiFi eventhough that other WiFi has 100% signal strength ?
I activated the "use wlan only if good strength available".. lets see how this works

I have multiple APs in my house and the only way I've ever got it to switch is by toggling wifi off and on (or loosing the first signal completely). This is an Android issue IINM, my GS2 and my N4 both have this issue.

I tried the "do not use weak WiFi".. didnt work.

It has never worked for me either. Didn't work on my GSM GNex or with the N4.

I think it's how most WiFi clients work, otherwise if you were in the middle of 2 equal signals, it would spend more time disconnecting and reconnecting creating a DOS attack on the 2 AP's and leaving you with no data.
As for 2 home wireless routers, use the same SSID and authentication settings for both, and put one on channel 1 and the other on channel 11.
Make one a AP only (no router, no firewall, no dhcp server) and connect it to a client wired port on the first one. You can roam between them like people in large offices do.

or I try to make a tasker profile
if wifi strenght below 20% and another wifi is available with more than 30%, connect to that one.. then wait 5 minutes ?

Wifi not reconnecting

What happened:
I am using a new Nexus 4 in various buildings on a campus (specifically, the University of Washington). For simplicity, let's assume that there are just two buildings, Building A and Building B.
There is a strong WiFi signal within both buildings, and I can connect to the WiFi network in either one. When I walk between buildings, the signal drops outside, and the phone switches to 3G networking (as expected).
Once I'm inside the other building, however, the WiFi does not always automatically reconnect. Instead, the phone will often remain on 3G mode, despite being in the presence of a strong WiFi signal.
If I restart the phone, the phone will then reconnect to the WiFi signal. Unless I do this, however, the phone will remain in 3G mode indefinitely. This drains the battery and results in high data usage with my phone plan.
Steps to reproduce the problem:
1. Connect to campus-wide WiFi.
2. Walk outside. WiFi connection will drop, and phone will switch to 3G.
3. Walk inside another building. Phone will remain in 3G mode, rather than switching back to WiFi, despite being in the presence of a strong WiFi signal.
4. Restart the phone. After rebooting, the phone will now connect to the WiFi network.
What you think the correct behavior should be:
The phone should automatically switch back to WiFi when in the presence of a suitable WiFi signal. A manual restart or manual reconnecting to the network should not be necessary.

What kernel are you using?

Did this issue occur before you were on PA rom 3.5?
If it didn't then I think it could be the rom if it's not then it's the school's wifi. It happens to me when I'm on campus too and I found out it the school's WiFi network was getting hammered and the signal was disrupted. No clue how that any of that happened.

Hi, I have the same problem. Did anyone manage to solve it? I have my Nexus 4 since yestereday and it's not reconnecting to my home wifi. Previous phone HTC Incredible S didn't have this issue and since that phone my wifi settings wasn't changed. I have AirLink AP, no name router and wifi is encoded with WPA. But i don't have to restart the phone to reconnect. It's enough to turn wifi on the phone off and on in settings. But it's really annoying. Thanks for hints.
And please excuse wrong expressions, I'm from Czech republic
Edit: I have stock rom, JB 4.2.2

Wifi problems on certain networds (CM11 Android 4.4)

I got a wifi problem on my defy with CM11 Android 4.4.
At home I can connect to my routers wifi perfect.
But in school I can't connect to any network. The school has two available networks, one with a password and one without password that authorizes you through the browser.
I'm unable to connect to either of these. They have full wifi signal, but when I click connect they immediately drop to 1 "bar" and disconnect. After the disconnect I got full wifi signal again, but when I connect to drops to zero immediately.
Any idea on how to fix this? Maybe some of the network drivers having problems with networks with a lot of users?
