How can I stop the WiFi radio from turning on by itself? - Galaxy S III Q&A, (US Carriers)

I just noticed when I woke up that the WiFi was turned on, even though I left it off when I went to sleep.
This is a major issue, because my phone downloads Play Music when connected to WiFi, and our home network has limited monthly usage...
Pretty screwed up that they'd release a phone that doesn't have an obvious option to disable this.
Any help?
To clarify, I'm trying to disable the feature that automatically turns on WiFi connectivity even though the phone is locked/sleeping/whatever.

data outage?

does anyone live in houston? I have not been able to get a data signal for about 4 to 5hours now and was wondering if it was my phone or an outage problem. I restarted my phone and pulled the battery but no data still. just asking to make sure it's not my phone.
running nero v3
Maybe you have it disable? Check under wireless and network, then mobile networks.

I went to check in the settings and the option 'use packet data' was not checked. I checked it and now I got my data back.

Any way to disable LTE 4G and 3G data?

I am always on wifi so I don't need LTE, 4G, HSPA or 3G.... is there any way I can force 2G or edge only on an AT&T locked Galaxy Note i717? I've looked all over the forums and people say go into the menu and select that option, but it doesn't work. Same with apps, don't work. I've read flashing a different modem will enable that option to work, but won't I need an unlocked phone to do so?

Why in the world would you want to do that. Why go to 2G? Why not just turn the data off

Well like I said I'm on wifi all day and don't need LTE killing my battery for no reason. And, so I can still send or receive pictures.
LTE/Data is automatically disabled when you connect to wifi. No need to do anything. It will turn itself on automatically to receive/send mms.

Im guess the op really meant to say how to turn it off when not using wifi?
otherwise, like you guys mentioned, it turns off automatcially when wifi connects
and 2G still exists?

So by forcing 2G I'm not going to see any battery improvement since it's automatically turned off since I'm always on wifi?

That is Apple's "innovation" for you right there. This is Android. Android turns off cellular data when on wifi and only turns it on when needed for MMS.
You notice how when on wifi you don't see a 4g icon? Send an mms and you will see it pop up long enough for the message to be sent and then disappear.
That is your phone automatically enabling/disabling cellular data when needed/not needed.
Ok, well to get this back on track I'd like to force 2G or even 3G no matter what. Any solution for me?
Dial *#*#4636#*#* and hit phone information. Scroll down and in the drop down list and choose GSM Only. Reboot.

Nope. Even on wifi, say If you're sending or receiving MMS it will use your data (4G or LTE). Also, unless you have it turned on while the phone is asleep, your phone will switch back to 4G for downloading or synchronize data. 2G takes longer to download information because of he slower speed which causes the phone to drain battery because the phone would still be downloading the data.

Looks like when you root and rom your phone you cant have that option. If your not in an lte area then choose lte/gsm auto. That should force u on 2G if no lte in area

I can't select anything except for LTE/GSM/CMDA auto. If I pick anything else it reverts back to that.

Problem: wifi on turns mobile data off

I am having a problem where any time I turn my wife on, my mobile data turns off (no 4G or 3g icon, also network signal info app shows no data). Is this a designed feature or is it a bug? Running stock Rogers firmware I747MVLLE8.

Well that's your problem bud. You're turning your wife on, not the wifi But on a serious note, this is an intended feature of android. When you turn on wifi it turns off mobile data to save your mobile data. If you dont mind me asking, why do you want your 4G to stay put if you are on wifi?

Avoid showering. Your wife won't get turned on as often. Problem solved.
Sorry. Couldn't resist the auto-correct fail... If you're on wifi, your 4g/3g automatically shuts off. That's normal.

It's definitely a "power saving feature" built into Android.

thats how it is on all android phones i blve at least all the ones ive had it wont send or rec pic msgs over wifi so it goes to the network then back to wifi
Alright thanks guys. Is there any way to turn this feature off? I want to keep mobile data on because I have really bad service at my house and I am trying to analyse it a bit.
You can just turn wifi off. You can't be connected to 2 data sources at the same time (that isn't an android thing). If wifi is off, you'll connect using 3g/4g instead.

Mobile Data Dropping

Okay I have been rooted for a day now and it seems that I am having some trouble staying connected to my mobile data. I did remove some bloat once I rooted but I don't think it has anything to do with that because when I am connected everything is fine. Is anyone else having this issue?

It's happened to me a few times but I think it's more of an LTE thing then an issue with the phone.

I'm on stock and see it happen at home as I get near the edge of Wi-fi range. The phone seems to continuously switch from mobile data to wi-fi, causing a lot of stutters when I'm streaming. I also had to switch to the 2.4 GHz channel from the router. The 5 GHz channel was worse and the phone seemed to be confused when I had it set up to connect to both channels. I'm not seeing LTE at our house, 3G at best.

Have you tried changing Settings->Power->Power Mode to High Performance?
That fixed it for me.
Well I had the issue a few times the night before and a couple times yesterday. Bit I think it might be the WiFi effect or what I'm calling it. The phone seems to want to auto connect to WiFi and it makes the mobile data stutter a bit.

I like having it enabled because it allows me to get on my network at home and work automatically. Which is helpful because I gave up my unlimited data. But if it does it again I may look into it.

unplug the cable modem and wireless router. plug in the cable modem first and then wait 2 minutes before you plug in the wireless router. while the wifi router is booting up reboot your phone.
if this help you please feel free to hit the thanks button.

some routers wont release the certificate so you have to go into router settings to release the dns lease for your phone

This looks to have been solved in the Sprint forums.
DLNA seems to get toggled on by default on some phones.
Go to settings->wifi->menu, advanced, uncheck DLNA
You can either toggle wifi or reboot at that point.
