Wifi to Mobile Behavior - Sprint Samsung Galaxy Note II

Is this phone supposed to seamlessly switch between wifi and mobile data connections (and vice-versa)?
Mine doesn't seem to do this. For example, if I am loading a web page using mobile (3G or LTE), then I turn on wifi, the loading ceases, and the browser gives me a connection error.
I'm not sure if this is normal or not. I would think the phone / OS would know enough to wait for and use the new connection. But it doesn't seem to do this.

Opera wont use Wifi

I mainly use 3g to browse the internet with opera, but if i connect to my wireless network and open opera it continues to use 3g. Is their any way i can make it use wireless? I thought it should automatically but it doesn't.
Thanks for any help.
be connected just to wifi
Is that the only way? I use push email that uses 3g and would sooner not disconnect that when i want to use opera over wifi.
I've just checked Internet explorer and that's fine using wifi, but opera still refuses to use it and sticks with 3g. Does anyone elses Touch HD do this?
I'll have a look at mine in a minute, but need to ask a daft question, how can i tell which data source the HD is using for its internet information at any one time?

You can go onto google and search for 'whats my ip' and use one of them sites to see if its your ip address or one used by your operator. Thanks very much.
Sorry, that took a bit longer than a minute.
Opera is using wifi here. However, when I first boot up my phone in my house (i.e. in wifi range) data connection is turned off and wifi is turned on by default. However, even if i switch on the data connection and fire up opera, it still uses wifi rather that 02 mobileweb.
I may talk a wlk down the street later and i'll see if the data connection will come on at bootup if a wifi isn't available
Have you tried going to settings->connections tab->connections->advanced tab->select networks and changing the default connection to "My Isp" or "My work network".
This may help although I have had very similar problems with opera using 3g instead of wifi. I reported the problem HTC and after an absolute age they wrote back saying "That shouldn't happen" without any real advice on what to do next. Since then I have always turned 3g off when turning wifi on. I used to use push email but of course turning off 3g buggers that up so I have settled for syncing every 15 minutes and as a side benefit that seems to have improved battery life.

I've tried what you have suggested and opera did use the wifi, however when i turn wifi off it won't use 3g until i go back into those settings and set it to do so.
I've noticed that if i turn my phone on and don't use the 3g connection opera will use wifi fine, but once i turn wifi off or go out of range and use 3g then return to wifi opera refuses to use it and sticks with 3g. I just don't understand why it's fine using wifi so long as it hasn't used 3g.

Tip: Market app (wireless access)

As I mentioned in my earlier thread I recently bought a Motorola Defy. Like many other users that I read about before purchasing my first android smartphone I was not able to open Google Market app after a factory reset.
My hint is based on my own experience and I hope it serves someone else well with similar issue.
As I write this message I have no data plan on my contract and I intend to use wireless connection for emailing, internet browsing, and the Market app. Once I completed the initial setup I put my handset's network mode to 2G only. I was worried to be charged for accessing data on 3G.
I had no problem using the Market app initially over the wireless connection until I did a refactory reset to re-setup my handset properly second time round. It was then the Market app stopped working and not even a master reset resolves the problem and then I was considering to root the handset to remove certain folders as a solution to the problem.
Everytime I laucnhed the Market app it stuck at Terms and Services page. It then occurred to me to change the network mode to Automatic and switch off the wireless connection to see what would happen. Next time I laucnhed the Market app it took me straight to the market's home page. It took me two days to figure this out : (
Once I was in the market I switched the network mode back to 2G only and turned on the wireless again. Everything is working just fine now. For the porpose of this thread I powered off the handset and turned it on again to see if my last settings i.e. 2G only still launches the Market app successfully or not. I can confirm that the Market app works just fine over the wireless connection just fine with 2G only network mode.
BTW, the batter life of this handset is so impressive. I used it one and half day very extensively (over 20 times of restarting the handset alone) and I was very surprised lasted that long. On moderate use and proper battery management (no widgets, no 24 wireless connection), and putting it on air plane mode at nights I would get over 2.5 days before charging is required.
I can't wait for Android 2.2 release to make this handset even more productive for me : )

I think you may have a misconception of 2G versus 3G. They are different technologies. When your phone is in 2G mode, it uses one type of network for both voice and data. In 3G mode it uses another type which provides better voice quality and faster data speeds.
Either way your phone will still try to access data unless you turn off mobile data. If it's in 2G mode and you see the little "E" icon up in the notification area, it's still accessing mobile data - just at a slower rate.

Thank you for your inputs. I'm very new in the world of smartphones but learning fast.
I searched around to find out how to disable Mobile data and chosen this method *#*#4636#*#* and changed my network type to GSM for best coverage and battery life now. I can confirm the Masrket app still works with wireless connection.
Changing to GSM only does not disable mobile data.

I disabled the Mobile Data option by pressing the Settings button then More>Disable Mobile Data. It was then I noticed the options for changing my network type beyond just 2G and 3G.

Did that work then? You no longer connect with mobile date, I'm asking because I have now ordered my Defy but like you don't have a network plan so need a workaround.

Right ok, thanks for clarifying
In Froyo there is a mobile data toggle in the regular menus, and on all Sense phones too. Is there one on Blur phones? I guess not.
Another way to block data is to go to your APN list and fudge the entry (e.g. change epc.tmobile.com to epc.tmobile.com.nodata).

The only way I can assure you I have successfully disabled Mobile Data by looking at the reception icon in notification bar that no longer displays G, H, E, and 3G at anytime.

[Q] Delay in connection changeover?

Currently trialing CM9/Franco;
Anyhow, whilst streaming data (SIP/streaming radio/etc) connected to wifi after leaving range of the AP, there's a drop (audio) while the mobile data connection is reestablished (?). SetDNS has a notification pop of the changeover to the dns servers used by the hsdpa ap, so I'm guessing that it's resolving a new address every time that wifi is detached?
Is this normal behavior for ICS/android as a whole? Is there any method to keep active on the mobile data side, wifi on and preferred, so when one leaves the wifi area the changeover is relatively nonexistent rather than the 5-10 seconds at hand? That's enough to kill a phone call
I'd imagine that in some sense something is retained for the sms push, but I'm guessing that's...well, separate.
Of course there will be a break in streaming switching from WiFi to Mobile data, unless the app uses a large buffer and you're on a delay.
When you're on WiFi, Mobile data is turned off. Keeping both on would defeat (or worse) the battery savings offered by staying on WiFi. Both running at once wouldn't help anything.
You're not going to be able to hold a SIP call between WiFi and Mobile data, you won't be able to consistently get a quick enough handoff to do that. Keep in mind that for things like WiFi calling on T-Mobile devices, they needed a completely separate chip in the phone and specialized software to handle a phone call switch from WiFi to Mobile network seamlessly. That just gives you an example of the extra hurdles it takes to do something like that.

Smart Network Switch option Missing?

I have a Verizon G4 and have one major gripe.
At my workplace, the wifi is somewhat spotty and it's a guest network that requires authenticating (clicking an "i agree" button)
So my phone will, throughout the day, as it detects the "weak" signal, automatically turn off that network due to "unreliable internet connection".
Even as I'm back in an area with a strong signal, now my phone is ignoring that and stuck trying to use mobile network. I have to go into my network list and manually tell it to reconnect.
During all of this, wifi is enabled the entire time.
I see where others have had the same problem on other phones and have turned off "Smart Network Switch" and I even read where someone had done this on a LG G4 (not verizon).
So I'm thinking this is something Verizon removed. Anyone have any ideas?
Smart Network Switch is just a feature that checks for a "data" connection over wifi and switches to use Mobile Data if WiFi loses internet access.
I am not sure the G4 has this. When I am connected to WiFi with a bad signal, it will just send me a popup telling me the WiFi has no internet access and whether to use Mobile Data or not. The feature you are looking for is "Avoid bad WiFi Connections", which is the same thing with a different name. Just make sure that is OFF. That will force WiFi to use WiFi as the only connection.
And it sounds like your wireless network sucks and needs to be upgraded to a corporate solution.
Just FYI, in my WiFi > Advanced WiFi settings, I have everything unchecked + "Keep WiFi on when screen is off" = Yes.
Well "avoid bad Wi-Fi connections" is off. Read on another forum that the mobile version I think it was had the smart network option.
I have the same options as you except I also allow Wi-Fi scanning.
I have tried with that one both on and off and see the same behavior.
I never get a popup, it just ignores that wifi connection and used mobile data. When I look at my Wi-Fi list, it'll say something about unreliable internet connection in small text,on the Wi-Fi network that it disconnected from. Surely I'm not the only one seeing this.. :/
Beats me. Sounds like the Access point you are connecting to has a bad internet connection. What is happening is you are connected to the WiFi and it notices that the WiFi AP is either dropping internet connection (Google pings google servers to test connections) or bouncing.
In order to keep from losing a data connection, it seems to be switching to your cellular network.
I see this often because we install APs (I am a network engineer). I think your phone is trying to protect you and that is normal behavior. Here is another scenerio: In a hotel, wifi is always set to OPEN. If your phone automatically connects to the hotels network, you will lose a data connection because Hotels require you to "sign-in", just like most free wifi places do. The phone sees that your phones WiFi connection is not accessing the internet and making sure you are good.
I am not sure how often it "checks" the wifi for a good connection or if it ever does once it switches.

Issues with Mobile Data

I have an Unlocked HTC 10 that I bought directly from HTC. Sometime, when I try to send a text and I'm on Wifi, whether I have a connection to my mobile data or not, the attempt is an automatic failure, even if I try to resend. If I turn off wifi, it won't enable my data connection, even if I turn it off then back on. It forces me to toggle airplane mode on then off If I want to send a text or browse the web. Also, to make things worse, the issue is completely random. I have no idea that it has happened until I try to send a text. TBH, I'm not even sure if wifi is part of the problem, like maybe it is disconnecting from Mobile Data regardless. If it matters, my carrier is T-Mobile.
Keep in mind, I have wifi calling disabled because it was more trouble than it was worth. But for some reason, the phone won't switch to data without my intervention. If I go out of range of the wifi, it will switch, but not all of the time.
Like right now, under my connection settings, Mobile Data says "Disconnected" even though it is turned on. When I just toggled Airplane Mode like I stated above, the connection was established immediately.
Why is the phone not connecting to the Mobile Network automatically? It seems like common sense when it comes to smart phones nowadays and is really annoying when I send a text, only to find out 30 minutes later, it didn't even try.
From other threads it seems to be an issue with the most recent update from HTC. Only fix right now is to flash a ROM that isn't running the latest update.
