[Q] Disable automatic WiFi connecting?

Is there a way to disable automatic WiFi connections when WiFi is on?
I was able to get around the automatic connection to my workplace's WiFi (they block sites and require a PC-generated pin to log in, thus I have no actual data if I forget to turn off WiFi) by checking that "Block Network Notification" box. I do have to connect to it at times which is the only reason I haven't forgotten the network.
But.. anytime I walk into a Starbucks, it'll connect to its WiFi network automatically. I went to AT&T Park this past weekend and it did the same thing (didn't realize until doing anything took forever). 4G/LTE is much faster than using these WiFi networks and I hate having to go in and turn off WiFi when I'm in public areas. I walk into range of these networks I don't know about and it automatically connects which is irritating.

Not sure about a built in setting to not connect to certain networks without forgetting them, but you could just put a WiFI toggle widget somewhere

I'm running the EQS from Android Revolution so I do have that option. Just hate when I forget to turn it back on when I get home.. lol

Well, you can always pull up the list of networks and long press each one. Then you can block it. Over time you will block all the places you generally go.

I figured I'd need to do that. Just wish it didn't automatically connect to WiFi networks I've never seen.

My TMO doesn't do that; it just alerts me that there are open networks available.

Auto Turn Off Mobile Data When Connected to WiFi

Does anyone know of an app that will automatically turn off mobile data when i'm successfully connected to a WiFi connection have have internet access through it.
The app should do something like this...
1. Check for WiFi connection
2. If WiFi = connected, then test WiFi connection
3. If connection = Good, then turn off Mobile Data, else leave Data connection ON
If you suggest Tasker, then you better follow it up with a full write-up on how to set it up on Tasker.

I believe (someone will correct me if I'm wrong) that Android is programmed to use wifi when it's available, even though your data connection looks as if it's on.
If you're not happy with that, Automate It should be able to do something for you. I have Automate It Pro set to turn off wifi & data at midnight, for example, to avoid the nuisance of emails pinging me in the middle of the night. And it switches wifi & sync on at 09:00 each day. Very useful tool, simpler than Tasker, so no tutorial from me...
There are a few Automate apps in the Play Store - it's this one:
https://play.google.com/store/apps/details?id=AutomateIt.mainPackage
This free version allows you 3 (as I recall) triggers - if you need more it's not too expensive to buy Pro.

I use RadioControl to handle that for me.
https://play.google.com/store/apps/details?id=com.nikhilparanjape.radiocontrol&hl=en
It requires root, and it's not perfect. But it works well enough for me.

Try smart radio xposed module.

Tasker does it pretty simply, but it needs root access..
Set up (2) tasks - I called mine Data Off & Data On. You will need to select "Net/Mobile Data" and then set "On" or "Off" respectively. Next set up your profile. Select "State/Net/Wifi Connected", and leave everything empty and save. This will trigger the profile when any wifi is connected. (Optionally, you could set it to your home or work wifi, etc). Your "task" will be "Data Off", then add an "exit task" for "Data On" (by long pressing the Data On and selecting "exit task").

^^^^ This. Android has done this for years. Some devices have the ability to keep mobile data on with wifi, but those usually default to OFF.
Note in the screenshot below that my Cellular network state (mobile data) is "Disconnected"

Do you have a ROM that has that option and it is enabled?

Running SIX ROM - Just checked, that option is disabled in the Dev Settings / connected to good wifi / and cellular is active...

¯\_(ツ)_/¯
Now it is a question for that rom dev.

Mobile Data Auto Off

Could not find an app where once Wifi is connected, Mobile Data is disable and enable when there is no Wifi connection.
Hope someone can help, thank you.

when the wifi is connected mobile data automatically turns off you dont need a app :/

Thanks are you referring to the Auto Network Switch under the Wifi setting?
When I set to Yes it gave a warning that it may auto switch to Mobile Data.
Suspect that if Wifi is not strong but still connected, it may switch to Mobile Data to get better connection which I do not want.

I'm in the complete opposite camp, how I wish there's an option for the phone to automatically switch to mobile data when the wifi becomes practically unusable.
There's a wifi deadspot in my house where I often use the phone, and contrary to what you suspect, my observations indicate that as long as there's a wifi connection, no matter how weak the signal, the phone will try its best to send and receive packets over wifi.
I usually have to manually switch off wifi.

Thanks for your feedback.
I will monitor whether the outcome is similar like yours.
I will turn ON both the Mobile Data and Wifi and using the Wifi preference setting.
If it works as you have stated, I will be very happy.
My priority is saving the cost from Mobile Data which is expensive to me.
I would like to control all downloads/updates of apps through Wifi.
Will use Mobile Data only when Wifi is not available/connected.

There is an option in developer settings to keep mobile data active even when Wi-Fi is connected. That may help with your Wi-Fi dead zone.

I think this option works for one device only.
I would rather recommend deploying a repeater for the Wifi signal, which will serves all devices at the dead spot.
A simple repeater should cost about USD10/

Thanks Pakman123 and mhaha, for sharing your experience.
So far testing as recommended works according to your views.
For mhaha, I believe a wifi signal repeater set up will resolve your concern.

You can look at which apps are thirsty data eaters in settings under mobile data usage. Then click on the hungry app, untick background data.
Turning off background data will keep the apps restricted to WiFi slurping.

Thanks for looking up.
Appreciate your good suggestion.

Question Data connection is active even when on WiFi

Hi all,
I'm noticing that the data connection seems to be active even when on WiFi. Is there any option that I need to disable so that the phone runs entirely on WiFi. I looked in the developer options and keep data alive option is unchecked. Am I missing something?

Hi, just go into Wi-Fi Settings / Advanced and switch off tab (Switch to mobile data)
That's all.

Hi. Thanks for this but this option was never enabled in the first place. Anyways, it's self corrected now...aah..the wonders of the tech world

It's enabled by default just to keep your internet connection stable when wi-fi has an issues.

It will re-appear occasionally. Even if you turn off the "Switch to Mobile Data" setting, the mobile data icons and wifi icons will appear concurrently on the status bar. This happens even when the wifi connection is solid. Usually the mobile data icon disappears after a few seconds or minutes on its own. I'm not sure if its by design (for MMS or RCS or something else) or if it's a bug. But you're not the only one seeing this. My colleague has an S21U too and he shared a similar experience.

I'm suffering from the opposite problem!
I *WANT* to keep mobile data enabled while connected to Wi-Fi, but the setting on my phone has no effect! When I turn on the setting, my phone will still ignore mobile data.
I verify this by connecting to my dashcam via Wi-Fi. The dashcam does not provide any internet via Wi-Fi, but merely allows my phone to view the dashcam output and stored files. But once I connect my phone to the dashcam, then my phone has no connection to the internet. I can't force it to use the mobile data at that point. The phone is not behaving as it should. My older phone, LG G6, is able to successfully connect to the dashcam and still access the data through the cell signal.
The S21 Ultra simply cannot achieve this. I have the T-mobile variant, in the US.
I believe this is a bug. Can you get this setting to actually work? Like maybe test it by connecting your phone to your Wi-Fi router but disconnect the modem from the Wi-Fi router?
I'll post a separate thread for this, because I think it's a bug and maybe others are suffering from it without realizing.

Question Wifi calls

Can anyone tell me if the radio has to be on in order to make wifi calls. When I'm in airplane mode and connected to a wireless network I get a message to turn airplane mode off. I have really bad cell service where I am and making calls is hit and miss.

I keep my radio off all the time (unless I leave my house) wifi on, airplane mode off and make and receive calls just fine.

If you have airplane mode off how are you turning the radio off? That's what I'm using to turn it on or off.

Mobile data always active in developer options set to off and I toggle mobile data off in Internet options. Unless I'm misunderstanding that should accomplish what your trying to do. For me this gives me wifi calling and receiving while I'm home (cause like you I have terrible reception) but when I leave my home and can pick up a signal I will still get calls etc

I must be missing something. I've turned off mobile data always active off in developer options and mobile data off in internet options. Right now I have no cell service, because it's so crappy here, am connected to my network but I still can't make calls. When I try I get a "mobile network is not available" error.

Check out under Network & internet, then internet. Your mobile network should be listed on top. ( I use google fi and it is listed) click the setting and make sure wifi calls is turned on. If it isn't there for you I would look around or check with your provider and make sure they allow wifi calling?
Or maybe someone else that uses the same provider as you can chime in here.

Thanks for helping me on this. Wifi calling is turned on. My carrier is Verizon. Could you look on your phone and tell me what it says below wifi calling, the smaller text, under Network & Internet, internet. Mine says "Call over mobile network" when wifi calling is enabled and "Off" when it's disabled. The call over mobile network seems to imply to be that wifi calling isn't active.

Yeah seems so. Mine says mobile data won't auto connect.
I'm unsure if it will help you however can't hurt to check or try. Under my provider (google fi) I click on the gear and my settings are mobile data, roaming, w+ connections and allow 2g are toggled off. My preferred network type is fixed on LTE and off course wi-fi calling under calling.
I checked under verizon and it should allow the wifi calling however it isn't very clear if it only allows it as a fall back option.
