WiFi won't connect to know Networks when screen is off - Samsung Galaxy S7 Edge Questions and Answers

As the title suggests, my phone will not connect to known WiFi networks if I do not wake the phone myself.
Image being away from home, having both mobile data and WiFi enabled. The screen is off throughout the whole time and when I reach home it is supposed to connect to my WiFi. Instead, it connects to my WiFi only if I wake the phone. If I leave the phone sleeping (standby) it will stay on mobile data, unless I wake the phone myself.
Is this regular behaviour?
PS. The phone has not problem retaining connection to WiFi networks when sleeping. It just won't make a new connection even to know networks.

There is a setting in wifi settings under advanced where you can change how and when the wifi must be on/off.

If you mean "Keep WiFi on during sleep", I have it enabled already!

Have you played around with power saving settings?

Auto switch from wifi to data connection

This seems like I've got something setup wrong. When I am in my office, my phone works great and it connects using the WiFi here. The problem comes what I leave the office and go someplace that doesn't have WiFi. If I want to connect to the internet for example, I have to go to settings->connections->connections->advanced->select networks-> and then change from "My work Network" to verizon wireless. Of course, when I get back to work (or anywhere with a wifi connection) I have to remember to change the phone back to "My work Network".
Is there a way to automate this?
As a second question, some apps seem to always use the data connection even if the phone is on a wifi connection already. Is there a way to change this behaviour as well?
Anybody? Seems like something everyone could use.
I am not sure how you have your device set up or which rom you are using, but my device does not behave in this manner.
My device is almost exactly opposite. It is always connected to data network unless I force it to use wifi. I have not messed with any settings besides setting up my wifi connection. Interesting.

I'm using DCD's ROM. And your issue sounds exactly like mine. It stays on data until I force it onto WiFi and then it will stay on WiFi until I force it on data. Kind of a pain if you ask me.
1st Question - Go to Start -> Settings -> Connections -> WiFi -> Menu -> Advanced and select your "Turn Off WiFi opition if not connected in __"
2nd Question - Idk, but I want that too, so that when I turn on my WiFi, my data connection turns off, and when I turn my WiFi off, my data turns back on, but I haven't found anything for that yet.

Turn off wifi when unlocking phone

Yes I have searched for this but I just get threads that tell you how to put a quicklink on to turn them off. Basically everytime I unlock the phone it automatically connects to 3G, how can I turn this off?
TIA
Still got this problem, it seems to happen when I get texts or calls as well. The display will
light up and connects the 3G, even happens overnight and uses a lot of the battery. I've turned all the auto stuff off but it still does it! Any ideas???
to stop 3g altogether you can try.... settings menu all settings connections advanced networks and disable hsdpa.

Connect to WiFi network timeout?

Hello. I'm sure that this must have been discussed but I cannot find the answer using search. As is surely normal, I use WiFi within the home and GPRS when there is no WiFi available. If WiFi is connected and I go out for a short while, then when I get back in a WiFi area, the WiFi is still connected. However, if I go away for a long time, and GPRS is used for perhaps a regular weather update, then the WiFi disconnects and has to be manually reconnected upon return to home. This leads to GPRS being used in a WiFi area unnecessarily if you forget to re-connect WiFi. Is there a WiFi connection timeout value or any other setting that can be changed? My old TyTN II did not have this problem. Thanks.
Try this CAB
It disable disconnecting WiFi when phone is in sleep mode and with this phone automaticly connects to WiFi when Leo will be in range.
Thanks Franq_23_pl. I think that the CAB just stops WiFi disconnecting when the device is in sleep mode. That will just drain the battery, surely? My old TyTN used to disable WiFi when in sleep mode, but as soon as you switched it on again, WiFi would be enabled and it would connect if in range. The problem with my HD2/Leo is that if I am away from my WiFi for some considerable time (ie, most of the day), then when I get back home and switch the device on, WiFi is disabled, and I have to manually toggle in on. So my question is..... What are the circumstances that cause WiFi to disable itself, and Is there some way of stopping it happening?
OIC now. I think you having some battery saving app and this app turning off WiFi when iz not used. What apps or registry mods you have installed on Leo?
You have the same behavior after hard reset?
My Leo don't disable WiFi. When i go outside (for ex to work) and back after few hours my Leo connecting to my home wireless network automaticly.
I remember, that i had the same problem like you and it was caused by app, which had duty to save battery.

[Q] Wifi goes off on stand-by

Hello to all I have the following problem: When the phone goes in standby i noticed that after a few minutes the phone disconnects from the internet then resume immediately as soon as I touch the phone and the screen turn on.
I have this problem with both Wifi and with the data connection.
I tried to solve the problem with the wifi option enabled in (Settings -> WiFi -> Advanced -> Wifi sleep policy) setting it to Never. But I notice that practically when i wake up the phone from standby , he is not using the wifi connection , but the data connection, and after a few second he will re-connect to wifi.when I'm not using more wifi, but the data connection.
From what I understand after X minutes in Stand by Android will disable the wifi and uses the data connection, and when i "wake up" the phone by turning the phone screen after a few seconds reconnects with wifi.
It 'really frustrating to have internet to that goes "on and off" especially when i am at work and the signal for the data connection is not present, in this case i can't even receive email or whatapp message when the phone in in stand by
Is there a way to force the phone to always use wifi even when it is in standby mode without the "support" of the data connection?
Hi!
up please
well actually if wifi policy is set to never, it should NEVER turn wifi off when the phone is in stand-by (at least it doesnt turn off on my phone), thats just how it works.. have u tried turning ur data connection off ? does it still disconnect ?

If i disable the data connection, the wifi connection just turn off after x minutes when the phone is in the stand by (even if i set to "Never" the wifi sleep policy) and will turn on after few second when i turn on the display. So what can be the problem?
N.B. I have DISABLED all "power save" option and there IS NOT such app like "battery safe" etc...,i have also tried to reset my phone. But the problem is always the same.

Well, actualiy, the policy says: "Keep Wi-Fi ON durung sleep", so you should set it to "Always".
So, did you fix the problem?

Turn on WIFI automatically not working

The wifi setting "turn on wifi automatically" in the advance settings use to work like a champ but for some reason it won't turn off when i'm outiside of my wifi signal range. I can turn off wifi manually and when i get within a saved wifi signal it will turn wifi on.
Has anyone experienced this?
Any advice will be appreciated!
My WiFi never turned off automatically on its own. I had to create Bixby Routines to turn WiFi off after leaving my apartment and turn it back on when I got home.
My phone would constantly be connecting to any available XFINITY Hotspots which is probably why that setting never worked for me the same way it worked for you.
Could your phone be doing something similar and connecting to Hotspots or open WiFi networks without you realizing it?
Mine has never turned off automatically either, it does turn on automatically when im in range, but i have also setup Bixby routines so im not sure if it turns off automatically now or not.
My hot spot is disabled but before this last update my wifi would turn on and off automatically. Oh Well luckily we have bixby routines lol
Thanks guys!
