Here's a classic problem I've been having:
I have wifi enabled at home, and it works great. I walk out to my car parked on the street, and from here my phone still sees my wifi network, but it has a very weak connection and basically can't transmit any data. I open Google Navigation to get directions to drive somewhere, and the phone just sits there trying to find directions, or connect to server, etc.
It would seem that whenever my phone can find a weak or public wifi (which requires a login-screen and does not actually "connect" to the internet), then I essentially get no data connection whatsoever. Isn't there supposed to be a function in the phone that will automatically switch over to 3G or whatever data network is available to fill in the gaps?
This is really annoying me, as Minneapolis has public wifi everywhere, which my phone thinks is "connected" when its really not, so basically its a coin flip as to whether my data connection will work when I'm driving.
Try turning off Wi-Fi?
Of course, I do turn off wifi and the problem is gone, but I seldom remember to do it on my first time. It's most apparent and annoying when I do a voice command or voice search while driving, and then it says "connection error" and I feel like chucking my phone out the window.
If I had true 4G and an unlimited data plan, I'd probably never even bother with toggling wifi on, but as it stands now, with a 200MB plan, I really need to keep wifi on whenever possible.
Is this a common occurrence with Captivate, or Android in general? I ask because this issue just came up yesterday, and I just got owned by an iPhone4 user. We both wondered if it was going to rain soon, so we both opened our browsers, and I was stuck looking at this stupid public wifi login screen, and was putzing around with wifi, when BAM, he just shows me his iPhone with fully loaded weather radar, etc. Hence I wanted to get this issue resolved now more than ever.
Not sure if the phone has this setting but windows 7 has an option to turn auto connect to open wifi spots off. So you gave to manually connect.

When I drive to work my phone at some point drops connection to tmobile network then goes to searching and stays there until I turn airplane mode on and off, then it will reconnect to network. It's annoying to have to do the airplane mode thing to get it to reconnect to the network. I have checked the network settings and its set to auto connect or auto register, so I am not sure what the problem is. Anyone have this issue? I am sorta new to root and I am pretty sure I didnt unistall anything necessary, just normal bloatware..
Nevermind, called customer service, eventually got someone techinically savy, I got a bad sim card that wont switch towers automatically. Going to the store to pick up new sim after work.
I have it enabled and it says it auto turns off WiFi and back on when near used wifi locations but it doesn't do that at all. Does it simplyeave WiFi on but low energy?

Yeah it works.
How do you know it doesn't do it? Cellular phones hand off betwixt cellular and wifi all the time.
When and how often it does is based on some under the hood shenanigans that we dont know about.

I drive away from my house. WiFi stays on but not connected. Screenshot says wifi will turn on when near known connections but it never turns off ?

I don't think it's supposed to turn off. What that phrase means is that it will connect to WiFi when it's near a saved access point and will use mobile data when none are nearby, but WiFi will still remain on.
What adaptive WiFi does is it will use mobile data even if it's connected to a WiFi access point if the WiFi signal is bad.
I'm not sure what adaptive wifi supposed to do, I have it off and it switches between wifi and cell as it should. Is it switching in the middle of data transfer or something? Because right now I probably drop connection if move outside wifi range and will be on cell tower on the next redial. But to tell truth I never tested it.
So basically it's a gimmick, because Wifi as it is, will auto-connect to previously connected networks as long as you had wifi on. If i'm interpreting the screenshot properly the feature "turns on" wifi, therefore, it must be able to turn it off? I've even manually turned it off to see if it will turn itself back on when i get back home and nothing either.
No documentation on Samsung's site as far as i can find

Basically if you're connected to WiFi but have crappy signal like .2 kbps, it will start using your mobile data even if you're still connected to that WiFi. With adaptive WiFi turned off, it will keep using the crappy WiFi connection until you manually turn WiFi off or manually disconnect from the crappy network. Pretty much the reverse of WiFi calling (use WiFi if phone signal is crappy). Note the exceptions sentence at the bottom, it will not use mobile data even if the WiFi has a crappy signal if the crappy WiFi is exempted.
The "turn on" statement is correct, it will automatically turn on and connect to WiFi when it's in range of "trusted" access points (similar to "trusted devices" and "trusted places") but there is no automatic "turn off", at least, it hasn't done that while I've been using it.
OK i see what you are saying
wifi does not PHYSICALLY TURN OFF. wifi is still connected--the phone will auto switch to the stronger of the two. it won't turn the on screen "switch" off if that is what you are looking for.
its not a gimmick. it works if you are in an area with robust wifi and/or cellular. its supposed to work "in the background" so you don't know its going on.
google fi kinda does this. since google fi uses tmobile and sprint, the phone auto switches between the two carriers depending on which is stronger at the time. i've seen this happen by monitoring an app.

Not a gimmick at all. I work at a hospital that has wireless routers throughout that all piggy back the same access point. I see Adaptive wifi in action all day. Keeps me from losing my connectivity from my work portal.
don't think I want to have this on: I have limit on my cell data, let's say I start downloading something large, let's say 5- 10 GB movie from Amazon on wifi, then I go to my upstairs bedroom, wifi gets weaker, so it switches itself to stronger cell tower and eats my whole month data allotment in one evening, before I even notice? And all I had to do is keep the phone downstairs, next to the router to avoid it. Or am I missing something?

Exactly what happens to me when I leave home. My phone (old Note 7) will stay connected to my home network but won't be able to pull down any data from the net. It has to be manually turned off.

thanks for the education!!
Any 3rd party apps you can recommend that would do what i am looking for?
so an update. It work exactly how it says it would. I had to drive 7 miles out, but wifi automatically turned off, even with scanning off, once i got home it turned back on.
I like it. It works great for me.

Ah, that's the thing. I noticed my WiFi would automatically turn off sometimes and sometimes not, and I couldn't reproduce it reliably. It's most likely either distance or time you have to be away from the "trusted" access point.
Congrats, now you can forget about toggling WiFi forever!
I think this setting has been screwing with my wifi related Tasker profiles. Suspect it really does turn wifi off.
I used to switch my wifi off manually when leaving the house.
All this #[email protected]\%! public wifi, blocking my internet because asking to log in....
Any shop or restaurant where you walk in does it.
And you do not know it, till you search the web and see that there is no internet at all till you switch your wifi off or log in to the shops fishing routers.
Adaptive wifi is a must have and a great improvement.
E.g. walk in a MacDonald's with adaptive switched on or off, you will see it is mother's little helper.
You need to have enough data from your provider of course.

Now that is some sweet use of the English language!
Hello,
I've used my Mi A2 around 2 weeks now and I'm really satisfied with the phone. However, I got some annoying issue about wifi. When the signal strength of wifi is not so strong (below -70 dbm), it tends to disconnect for around 10-20 sec and then reconnected again. This happened to me like 10 times since I got the phone. And wifi works perfectly without disconnections when the signal strength is strong enough.
Does anyone experience this issue? Or I got a defected device?
Thank you
Same here, sometimes it just disconnects ...

It is a normal stock android behavior, because android detects that signal of wi-fi is to low, and tries to switch automatically to GSM mobile data, or to another wi-fi if it is available in the area.
I don't have this happen but wifi signal is strong and also; gsm data is turned off.
That *may* help to turn that off possibly, as it obviously can't (now) switch to it?

Even if mobile network is off? Is there a way to change such behavior? I tried to find in the setting but what I just found is Aggressive WiFi to mobile handover, which was already turned off.

It happened both when mobile network was on or off.

I think that it is called smart wifi, or wifi+ option in other types of android OS, and here it is just a automatic option in stock android i guess.
I don't mind it, because it will change my wifi router AP if it get stuck, and need an reboot, so it will automatically switch to another closest one that works.
You better think of some way to get a better signal then to turn off this function.
Try with aps like this on the link.

The thing is that wifi also disconnected when there's no other nearby networks to switch to. I did something to get better signal in my room but this still happened sometimes.
Hi. I have made a location based profile that uses my location to to switch on do not disturb on my OnePlus 3t but want to switch it to cell near as it is supposedly uses less battery. The profile works but it seems like the cell tower it uses isn't strong enough. Is there a way of adding a second cell if the scanning shows one or do I need to scan for longer moving about so more is picked up?
From the Tasker User guide - location without tears:
Create a*state context, select*Phone*then*Cell Near. Click Update and walk around a bit to scan for cell towers nearby.
About
Uses information about the cell towers the phone uses for telephony to record and match a location.
When the display is off, frequency of checks is controlled by*Prefs / Monitor / Display Off All Checks.
If your profile keeps deactivating, go back to the Cell Near state and click the magnifying glass icon to check for cells you may have missed in your scan.

That is what I have done but the profile switches off all the time. It seems like the tower my phone detect isn't the right one. Tried two different scans with the same result. (The scans identifies different signals but neither seems to be able to run the profile)

Did you do the second part, involving the magnifying glass? If you're bouncing off different towers while moving throughout your home, all of the towers will need to be selected.

Sorry I missed that. I'll try that and see what happens.
The profile also seems to deactivate when the screen goes off but not 100% about that
It seems to have sorted it!
Every time it stops working in have to add a new cell tower but that's fine as it works!!!
Have about ten now for this work based profile.
