3G when connected to WiFi

On most Android Devices, when you connect to WiFi, your 3G disappears. This doesn't occur on my 2.2 Defy. Is this normal?

Mine does that too, but not completely. After the upgrade WiFi always disconnects when the phone sleeps (in 2.2.1 US the setting to force WiFi had gone away), and it takes a while after a turn-on for WiFi to be re-established, after which the 3G icon goes away. BUT, this is not the case right after reboot when for the 3G icon to go away I need to first toggle WiFi off and on.

That's the crux; that setting is absent in 2.2.1 (as I mention in the text you quoted)

Do you still have ability to select preferences in wifi calling -- if so, does that help over-ride 3G with wifi?

The short answer; yes, and no, the long; had to rename the app first, and the Calling Preferences is there and it was set to WiFi preferred.
So, it seems that the WiFi behavior is one of those things that still needs fixing in the 34.4.9 release.

Yes mine does it too. It did it on 2.1, and now 2.2.1. After about a half hour the 3G icon goes away. Doesn't bother me.

Mine wasn't doing this on 2.1, and yes, it bothers me. I'm on a limited data plan, so I have to make sure that most of my big downloads happen through WiFi.

It still uses Wi-Fi even though both icons are showing. I track my use with NetCounter from the Market, and "Data" is always 0 (zero) when I have both icons.

[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?

Edit
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.

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 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.

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!

[Q] Ready to throw my GN against the wall. Wifi wont stay on!

Hi all, Im having a problem that is slowly driving me insane for the past 2 weeks. I surely cant be the only one. Anyway, I generally move between home and work daily, both have WIFI. When Im at home Im connected, all fine. I travel to work, WIFI isnt connected, again this is normal. I get into work and when I expect it be connected to WIFI it isnt, WIFI is off and I have to manually turn it back on to get it connected to WIFI again. Why do I have to do this? Why have all my other Android devices just worked normally and reconnect to known networks. Its soooo frustrating
Anyone have same problem or have a resolution?

What rom?What settings in phone wifi?

Both Stock rom, with and without the volume fix, and Modaco MCR4. Wifi settings are set as WIFI on even during sleep.
Is there some settings Im missing somewhere other than in Settings > Wireless & Netowrks > Wifi ??

Nope these are the settings.The strange thing for me is that your wifi turns off automatically

Try going to advanced WIFI settings and disable 'Avoid poor connections'

Yep. Try that. Only thing I can think of. My wifi was flaky with that setting on even 4 from my router. If that doesn't solve are you using any kind of task managing àpp?

I have posted this in other people's threads in regards to poor wifi reception. I recently purchased a 9250 through bell canada and have the same problem.
I have turned off the 'avoid poor connections' as well. It turns on and off on its own and can't get through a download of more then 5MB on wifi.
It will also reconnect on its own if I have left wifi turned on. I would say while WIFI is turned on I may actually be connected 30% of the time. This is 90% in 2 feet away from a router.

I'm having the same issue (wifi turning itself off) - noticed it the other day and just assume I'd caught the wi-fi button (I use extended controls). Happened again this morning and also just now as I got home.
I've not modded anything on my Nexus (4.0.1) - avoid poor connections has been disabled for a while.
I may test the theory, but betweek home and work is a wifi enabled bus journey, I never use it but it always tells me there's a wifi available. I might turn wifi notification off and see it if turns itself off before I get to work in the morning...

Left home with wifi on... Got to work and wifi was off? Wtf?
Could it be extended controls?

You are not the only one, it's happening to me in exactly the same scenario. Oddly enough it hasn't happened today.

i cant make out of your post thast the wifi on/off button turns of? or just the connection to the wifi adres?
i dont know about any sleep or auto turn of policy's as i didnt try it(i always turn off my wifi when travling)
but if its the last thing.
than the problem might not even be the GN.?
but the router it self.
even computer's and laptopt can have problems when the password is too long,or to different(hard characters like :';/.m,[email protected]#$%^&**(() ][ )
it might also be the MHZ setting,as the 20MHZ has wider range but can be disorted by machines like microwaves.
but the 40MHZ has lower range but wouldnt be disorted.
as there is also the channel option thats has been set wrong/or the pasword encryption. or any other router conflicting with the router you want to connect.
it might also be the router not liking your GN.(as my spica doesnt conect to my router at home,but all my other devices do.my router doesnt want to give a IP to my spica.)

It just happened to me again now, left the office whilst wifi was on and connected. Grabbed some lunch and returned (about 20 mins) and now my wifi button is set to off and I need to set it back to on.

Are there any policiys or settings for auto off?
you might also want to look into the power setting's,might be a power save feature.
And you are running stock? or??

Can't see any policy settings or any power save features. Running stock.

somehow I have fixed it. Problem is I don't know how.
Here is what I did in case anyone else needs help;
*From the 'My Vodafone' app, select wi-fi finder, in settings untick 'Enable BT Openzone'
*Settings, wi-fi, advanced, untick 'Network Notification', untick 'Avoid poor connections'
Not sure which of the above actually fixes it but my Wi-Fi has been on for about 1 1/2 days now.

Have you or when did you upgrade to 4.0.2? As the changelog mentions a wifi fixed. Only upgraded this morning so won't see if it has worked until I get home...

So I am still having this problem since day one. I have travelled through 3 countries and multiple cities and tried to use WIFI in at least 20+ different instances and the problem is the same.
It connects right away (really quickly actually) will stay connected for a bit then eventually loses connection.
I can't download any of the big packages for the games and so I can't play them. I won't use my data connection for anything over 100mb.
I got a message for an update yesterday. Updated the phone but I see no difference in the Android version number.
Anything happening with this?
I thought the update i was downloading was 4.0.2 but i guess it wasn't.
I am familar with updating and flashing from the galaxy s. But I want to use the phone completely stock for while.

I have just returned my nexus for a replacement. Lets see how it goes.
So far I have had the power shut off once while toggling the wifi widget (never happened on my other phone). And the wifi has disconnected twice. I have just done the update (not 4.0.2) and it seems to work a little better.

Called samsung yesterday after getting the replacement phone when it had the same issue (just as a reminder I have tried it on numerous routers/ap's) and they said they hadn't heard of the issue.
I said I was just calling to provide some feedback. They told me to return the phone yet again. I obviously believe I don't have a problem with the hardware at all. I figured if store let me return it, then why not.
Anyway onto my 3rd one today and the exact same problem.
I think that even though I am turning off "Avoid Poor Connections" it isn't actually turning that 'feature' off. Every so often and only if your watching the wifi settings it will say that it disconnected the wifi connection due to low signal.
Mind you all of this is 1' from my router while sitting at my computer. My galaxy S is sitting beside me and has maintained a wireless link to the router the entire time.

Wifi issue

Does anyone know how to stop the WiFi from turning on automatically ? I have all of the options for the WiFi off and I'll turn the WiFi of but my WiFi will still turn on and say there is a hotspot available.

You mean the options under Advanced in Wi-Fi settings you have off right? If so I am not sure I have not noticed my Wi-Fi coming on without me hitting the toggle.

Yes all the settings in advanced are unchecked,I will turn off my WiFi and next thing ya know I'm getting a notification that there is a hotspot available and sure enough my WiFi is on again! Its starting to get annoying that I get the hotspot notification all the time

That is odd, one of the options under advanced is to make it so it does not try to connect to hot spots in general, also the other says to make it not scan while Wi-Fi is off. If both those are unchecked and it is still happening then there is some sort of issue I would guess. Hopefully someone else with the issue pops in here after a bit.

Me too
Yes, this is happening to my Note 4 as well. All settings in WiFi>Advanced are "off" and when I go walking through the neighborhood and turn on the phone I get a screen showing a list of wi-fi networks.

Im gonna guess everyone has saw this already but thought i would post it anyway. In the advanced menu in wifi,there is a section called Always Allow Scanning. Description says "Let google location service and other applications scan for wifi networks, even when wifi is off". Sounds as if that could be the issue but if everything is already unchecked in the advanced settings menu, then im at a loss as well. Im gonna test this on my Note 4 and see if i am getting the same issue you guys are getting.

Nope no issues here i don't get that i turned it off, and i would know this cause if i walk in Walmart i use to get that on the the Wifi Hotspot not no more since i've turned it off, use to tell me the same for kmart or the AT&T Store where i live no more since i've turned it off!

Try disabling AT&T Smart Wifi. Could be the cause, especially if its alerting you to "hotspots".

I have the T Mobile version and it does the same. The white menu pops up telling that there is Wi Fi available, listing hotspots.
On my previous Note 3, it did not present itself as a page over my screen even if I had Wi Fi turned on. I simply had notifications of available wi fi's turned off. But it seems with the Note 4 one has to turn off wi fi completely for this to not show up?

Check in Location Services... Specifically the google stuff. One of them allows the use of your WiFi & GPS data even if they are turned off... Meaning if you choose the high accuracy mode (instead of GPS only) the location services will periodically turn those things on to better pinpoint your location (and send that data back to google)

[Q] Is there a fix for the Wifi Issues on Lollipop?

Recently purchased a 2013 Wifi only N7. Upgraded to Lollipop and continue to have intermittent WiFi issues, where WiFi will show connected in the notification area with an exclamation mark. This usually occurs after I docked the device and been away from it overnight or for several hours. The only way to get back on the network is by toggling WiFi off/on. There is another WiFi network in my home, but it is set to a different channel and we are far away from the neighbors. The AP is nearby with clear line of site, and other devices (e.g. HTC One, iPad) have no issues.
I have read that this is a general problem with Android 5.

I would check your Wi-Fi settings in settings, Wi-Fi, three dots, advanced.

There's not much to change in there. Since the nearest network is only 2.4ghz, I changed from automatic to 2.4ghz only. Not sure that's going to fix this.

What about your settings for WiFi being on or off during sleep? Is it set to always on?
