910F MM: WLAN doesn't automatically connect anymore - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi all,
I noticed a weird problem after I installed the latest Marshmallow update on my N910F. The WiFi will not connect as soon as I'm in range anymore, but it will connect immediately when I switch on the display.
I noticed the behavior because I configured a Tasker task that will wake up my PC as soon as I connect to my home WiFi. The last two days I noticed my PC was off when I came home so I switched on my phone and saw that the WiFi was not connected, I was home for 10-15 Minutes. A view seconds later after I switched on the display WiFi started to connect (and my PC also woke up because of my Tasker task).
Once the WiFi connection is established it will stay stable - I checked my router logs, so turning off the display will not disconnect the WiFi. Of course I set my WiFi to stay connected in standby.
Has anyone experienced a similar problem?

I was having issue not this kind but whenever i diconnect to my wifi and then again teconnect it again it takes time to surfing the internet about 2 minutes.when i open browser and any site it first shows connection time out then i have to wait 1-2 minutes then it loads the site.i dont know i have noticed new settings under development setting there is network setting in there there are lots of option.one option is connect to lollipop dhcp .i tried to check and uncheck that also but didnt work out.

Today it did not switch on my display when I came home but waited to see how long it would take my Note 4 to connect to my WiFi. After 25 Minutes it connected. I wonder if this is some "doze" feature.

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 not connecting but all looks correct.

This is a first time for this issue for me; my Wifi is scanning, but not connecting.
The settings look fine, I re-inputted the network passkey just to make sure, but it just doesn't connect...it just says scanning, though my home network is in the list.
My laptop can connect just fine as you can tell, I'm posting from it.
Can someone help?
Tried rebooting your modem/router?
I have this a lot of times waking up after sleep (I have the WiFi set to turn-off when the screen goes off)
Turn off then on the WiFi (wait a few seconds in between) resolves it.
(there are apps in the market where you can do this with a simple button press)
Well...I did reboot the router but had to go to work before I checked but it has to be the router...
I can connect just fine at work...
thanks for the suggestions...I'm glad it's working.

[Q] Change in wifi behavior since update

I have noticed this only since the latest update to the Note 3. Before when I left range of my home wifi the phone would go to LTE and upon returning home, automatically reconnect to my home wifi. Now it goes to 4g when I leave, but does not reconnect when I return home. Last night for example, I had been home for a couple of hours and wifi was still turned off and the phone was using 4g. When I manually turned on wifi, it connected immediately. I have played around with settings but can not seem to get it to reconnect automatically as it used to. Below are my advanced wifi settings. Thanks!
Notify: Off
Passpoint: Off
Sort by: Alpha
Keep on during sleep: Always
Always allow scanning: Unchecked
Auto network switch: Checked
I would swap the last 2 checks you have listed. The first check, even though it will scan intermittently, will not affect battery life enough to worry that much about. This also assists in location discovery. The second check will cause your phone to disconnect from your current wifi and force you to manually reconnect if there is ever an unstable connection with your WiFi that the phone detects.
Just my suggestion.
♢NoteIII♢
I did change those but may not have had that combo. The last one, auto network switch, I may have just toggled that off, then back on to try and get it to stick. Intuitively, to me at least, that seems to be exactly what was happening before and what I want now. It was automatically switching from wifi to 4g when I left, and automatically switching back on when I returned to my home network. It seems that turning that off would be the opposite of what I had before, but I will try. My home wifi network seems very stable. Five phones and six computers and none of us ever have trouble with it that we notice.
Thanks! I'll try those options and test it out.
Well I tried that for several days now and it did not work. Tonight, for example, I had been home for 3 hours and then noticed the phone was still using 4g. I switched on the wifi and it immediately connected. I think it is turning off when I am away for wifi for an extended period. I do not remember for sure, but I think before, wifi did not actually turn off. I think it just went out of range and then started using it again when I returned home. I don't really recall the specifics except that before I never had to do anything to get it to start using our home wifi network. lt would just automatically reconnect when I got home. Now unless I remember to turn wifi on manually, I could be home all weekend and still be on 4g.
Any other suggestions anyone might have would be appreciated. Thanks.

Several weird issues

Hi there,
I have my S8 Exynox version for more than one week and I am facing some strange issues that I cannot explain and I have never experienced them with my previous phones.
I have WiFi router (2.4GHz/5GHz) running OpenWRT and S8 is disconnecting or keeping connected but losing internet access. Many times when I unlock the phone I can see that it is not connected to WiFi and just connecting or there is a message "Connected to XXXX" indicated that the connection was somehow re-initiated. It seems to be more stable if I remove 5GHz network connection but still not reliable.
This is even more strange. When I enable WiFi on S8 and let it connect I am facing network connection dropouts on my LAN not only on WiFi but even on cable. I am listening network radio and the sound disappears randomly and the issue is gone if I disable WiFi on S8. Sometimes I even have to restart the router.
Settings changes randomly. I was navigating with Waze and there was no speed indication. I stopped and found out that it was disabled in settings although it was enabled my previous drive. And another time LTE was suddenly disabled. There was 3G/2G selected in Connection -> Mobile network -> Mode.
I am using Dropsync to synchronize several Dropbox folders with my phone. One of them is synchronized to Share folder in local storage. Yesterday I found out that there is some sync problem in Dropsync and it turned out that Share folder is not existing. Some process has obviously deleted that folder. Could it be that I run optimization in device maintenance?
I am using Nova launcher with Morena icon theme. I have selected some icon for Samsung calendar to have is consistent with the icon theme but it randomly changes to stock icon during the night.
It forgot BT pairing with my Garmin Forerunner. I had to pair them again.
I have enabled volume sync when I connected my JayBird earbuds for the first time but it was disabled again few days ago.
Does anybody else have issues like this?
Experienced the WiFi issues in the beginning too, it doesn't kill my ping any more at least not majorly and it seems to have stopped not being able to connect to my router properly. Can't say anything about the rest.
And how did you solve the WiFi issue?

I didn't, it resolved with time, it did seem to stop after rebooting my router one last time but I doubt that's it as I already did that once and the issue happened again.

Wifi keeps switching on an off

Dear all,
I'm experiencing a somewhat weird issue with my Xiaomi Mi A1 (Oreo) which started a couple of months ago.
My WiFi keeps switching on an off.
* When I turn off WiFi, 4G comes up. After a few seconds (I can leave the phone unlocked at the desk, it almost happens instantaneously) Wifi turns on by itself and connects (just as if I switched it on manually).
* When I activate the mobile Hotspot, it switches off after a few seconds, disconnecting all devices connected, only to switch on the regular Wifi after a few seconds and trying to connect to the next network.
* In random cases, Wifi just switches off despite being connected to a working network and while I'm using it.
This is somewhat annoying, and I didn't find any solutions online. Any ideas? Any more information you need (sorry, I'm new here)?
EDIT: This is not the "Turn on Wifi automatically" setting, and it is also not related to location services.
Flash stock rom, sounds like a software bug. Otherwise, return it while you still can.
Thanks.
