Wifi keep turning off and on ( Samsung S8 Europe; Android 7.0) - Samsung Galaxy S8 Questions and Answers

I can't be connected on wifi for more than 5 secs. It's just turning off and on. Tried turning off smart switch, bluetooth,etc and other solutions but it doesn't work for me. **** this bull****. Anyone?

Having an issue with my wifi aswell. Not the same as yours. My connection speed to my router seems to jump around randomly. Going from 400Mbps all the way down to 1Mbps and many speeds in between. Has been causing issues with browsing and downloading apps. Need to turn wifi off and on again and it'll work for a while. Never had these issues with my s7 edge.

I started experiencing the same thing after 15 days with wifi disconnecting and reconnecting on it's own.
I fixed it by going to settings>connections>more connections>reset networking. I then rebooted the phone and the wifi is now stable again.

I have the same issue..
Wifi keeps toggling on its own.
I tried resetting the network setting, Factory reset still the issue is same.
Not sure what to do.

[Q] T-Mo G2 Rooted/Stock OTA 2.3.4 Wont stay connected to wifi

I tried searching and I've not found this issue addressed, but I may just be doing it wrong. But, here it goes anyways...
This house has 3 T-Mobile G2s, all with the same OTA. Only mine is rooted. However, none of them will stay connected to wifi. The wifi icon is showing up and it says that I am connected to the access point, but in status it says that mobile network status is disconnected. I can't do anything data related after it times out. If I disable and re-enable wifi it stays connected for a bit before it goes dead again. The handset doesn't go into sleep/screen doesn't turn off. Before I updated I did a Factory Data Reset, then re-entered all my information then let it update. Is there anything I can do, or try?

Being that all 3 phones cannot stay connected I'd be inclined to say look at your router... I'm assuming you've done all the obvious things like reboots, battery pulls, "forgetting" your network and then re adding it? Are other devices in the home able to maintain a wifi connection... your computer, for example? You've tried resetting your router?
If the screen isn't timing out, have you checked your Display settings? What makes you think the screen timeout is related to the wifi problem?
Well in the past on my myTouch 3g... wifi at times would get wonky after the screen timed out/it went to sleep. So was just adding that information here. Yeah, there are at least 8-9 other wifi devices here that can connect to the router just fine and send/receive data. I've tried "forgetting" the access point and then re-adding it, resetting the router, battery pull... and the same thing happens. And the router doesn't have MAC address filtering either. Can't ping google.com or 72.14.204.105 from the phone, but my pc can just fine. If I disable wifi it works as it should. Its just I only have realllly slow EDGE service in the house.

Hmm... by default wifi should turn off when the screen times out. Unless you've changed the wifi sleep policy. I had mysterious wifi trouble before on a different device (endless "obtaining ip address" loops) and the only thing that worked for me was restoring an older nandroid. Obviously, you're no longer rooted and that's not an option... but it's super unusual that 3 G2 phones are experiencing the same problem. And they're all running the Gingerbread update, so maybe that's the common denominator. I'm sorry I couldn't be more helpful. I'd definitely pay T-Mobile a visit.
I've not messed with the wifi policy, but my last phone would just drop wifi completely and I had to forget/re-enter everything to get it back. If it was the update then I would think the problem would be more widespread. Going to try fiddling with the router some more since that would most likely be where the issue lies. All else fails will just rollback to an earlier nandroid, like you had to do, and seeing if I can't get at least mine consistent. Thanks for your help and letting me bounce ideas off of.

[Q] UK note 3 users. wifi problem with virgin media router

I sent my note 3 (sim free n9005) to repair one month ago because a sensor didn't work (another story). Now the sensor problem has been fixed. But there is another issue. The wifi keeps dropping. I mean wifi is completely turned off on my phone, then it tries to turn on, and off again... I have googled a while,it's not the wifi is slow, it's the wifi is completely turned off then it tries to turn it on, and keeps turning on and off. At first it happens occasionally and it can be turned on. Until several days ago, wifi could not be turned on at all. If I go into setting - connection - wifi, I will see it says 'turning on' but nothing happens. Reboot helps sometimes but the issue soon reappear. I did factory reset but no use. I would think it's the phone's problem. But When I go outside and test in public wifi (university wifi, MacDonald etc), it got no problem at all. So I began to think maybe there is something with the router. So I turned off my router, the wifi is turned on immediately and I can see all the wifi connections from my neighbours.
My router is virgin media netgear vmdg485 (100M fiber optical). I googled it, it seems specially made for Virgin media. It's a modem/router all-in-one device. Just wondering has anyone else got similar experience? B.T.W all other devices in my home connect to the wifi no problem at all. I think they may have upgraded my android software on the repair. I never had this problem before the repair. But android is the latest version (checked in settings). So I don't know what option I have on software side. Probably I need to try a new router?
And also I have tried everything I found on Internet (turn off switch network etc in advanced setting in wifi. turn off power saving for wifi, disable wifi direct/share, etc).

Hi,
I had a similar problem with my note and was advised to go into the wifi settings and deactivate "Scanning always available" and "Auto network switch".
I had this problem with a Virgin media router and where android was under the impression the connection was unstable it was deactivating the wifi to go back to the cellular.
This may be completely wrong but it solved it for me.
Hope this helps!
I had this issue and the only thing that solved it was a factory reset.
I had a similar problem with my Note 3 (SM-N9005) and Virgin Superhub 1
I hadn't previously noticed problems with wi fi at home when using different phones in the same location.
After much reading on support forum I concluded that many Superhub users believe the device is not very effective when operating as both a cable modem + wi fi router.
I opted for an expensive solution of buying a new wi fi router.
My Superhub now operates just as a cable modem and is connected via ethernet cable to the adjacent Asus RT-AC66U which does have the advantage of 802.11 ac.
Speed test result from Note 3 via wi fi setup described above.

Thanks paul, mine is super hub as well. I want to get a router to test, but worring if it doesn't solve the issue.
wow, that router is a lot of money, really hope it's not the router issue.

[Q] Wifi continuously scanning while phone has good wifi connection.

This started Feb 3rd or 4th. The phone will connect to the wifi network, with a good signal. It will then re-scan every 5 seconds or so. This is causing all sorts of data transfer issues from downloads freezing to apps losing connectivity while running.
I am running on Verizon.
Specs below: (Sorry can't direct link yet...need 10 posts)

imgur.com/TnK9wNr
I am now running Android 5.0 but had NOT updated to 5.0 when this problem started.
I scoured google a bit and found an ATT forum that is essentially reporting what I am.
forums.att.com/t5/Samsung-Discussion-Support/Samsung-Galaxy-S5-Wi-Fi-Connectivity-Problems-After-4-4-4-Update/td-p/4190704
All other devices on the network are operating without issue - phones and computers - as was mine until now.
I have power cycled everything.
I have checked the routers settings.
The phone has been power cycled several times.
The phone has had every wifi setting that would be causing this scanning, that I know, disabled.
The following are off in Wifi > Advanced:
Wifi notifications
Passpoint
Always allow scanning
Smart network switch
I then, after the above, updated to Android 5.0. The issue still persists. Help me please.
My device does this, too. Cant say I have ever really noticed, I dont know if it has always done this or not.
I am not experiencing any issues like you describe.
Now that I think about it, I think it will always scan at a set interval when you enter the Wifi settings. It assumes you are looking for a network to connect to. I doubt its scanning when you are not in that setting.
I had this problem the other day. I went to wifi settings and had it forget the network and then rebooted and reconnected to my wifi network and it seems to have resolved the issue. others have just switched airplane mode on and off and this fixed it. good luck

Wifi not working randomly

Hi,
I have a problem that my WiFi network disconnects and disappear from the list. Even if I search for network it will not show up.
It looks like a lot of the other WiFi networks around me is also missing when this is happening.
It will suddenly come back again and work as it should for several hours.
I have i locked to 2,4GHz, WiFi always on, scanning is on.
Had the same problem when I used Auto 2,4GHz/5GHz.
All other devices is working as they should. Have also reset the wireless router. (Netgear X4 R7500)
I have the same problem. When I turn the wifi off, and the back on again it discovers my router and connects.
Does anybody have a fix for this?
Same problem here. My 2,4ghz network sometimes just vanishes and shows up after a couple of minutes. And it just won't connect at all with my 5ghz network. My router is a D-link dir 868l. I'm on the latest firmware. My other devices all connect just fine, except for my 6p.
Updated to 6.0.1 and I have still problems. When I come back home, I need to turn off and on WiFi to reconnect. Wifi have not dropped since i updated to 6.0.1 yesterday.
Just curious
Who is your service provider? My girls 5x is connected to Sprint and she has no problems on my network. I have Tmobile on my 6p and it keeps dropping the wifi. Maybe its a Tmobile thing?
reset network config
I had the same problem and try to go to airplane mode on and off then even forget network and add back on. Work for a second and disconnected. So far this way work. Try this.
Got to Setting > Backup & reset > Network Settings reset
Hopefully this will work for you guys too.
Good luck! :good:
My brother has a Nexus 6p and the WiFi doesn't switch on at all after he updated to 6.0.1. I reflashed factory image of 6.0.1 again and it didn't work. I then flashed 6.0 but it still doesn't switch on. Any help?

Anyone have a solution to this problem? I still have this big active, and have been using mobile data since.

Wifi and 4G stuck together - how to fix this?

I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?
