Why does my wifi toggle itself off and on?!? (Video in thread) - Galaxy S 5 Q&A, Help & Troubleshooting

Many people have said to change routers but this happens in hotel rooms, on airplane wifi and at my own house. Its incredibly infuriating as well when you're using wifi calling as well. Does anyone else have this issue at all?
I'll have it connected. It'll work for 5 or so minutes then just keep continuously doing this!!!

No ideas?

T-Mobile sent out a new one. Having the same issue with the new phone too

I've had this phone now for 5 mos and this keeps happening. Am I seriously the only one with this issue?

Hi Atooraya,
your question/post was viewed a 179 times now, so I guess you have a unique problem there.
It might be related to a specific software you have installed (company VPN App., WIFI scanner etc.).
It might also be worth to check that "Smart Network Switch" option in the Wifi settings.
Good luck,
Matt

I get the same with Smart Network Switch turned on.
Switched it off and the problem goes away.

^^ This, WiFi settings > Disable Smart Switch, it's nothing but a PITA

WIFI issues

Hi Everyone,
I have a strange issue,
My wifi works, but today it won't recognize my work wifi even though it was connected to it on Friday.
I've tried everything I can think of to solve this issue, but the problem is only at work.
I just tried a free spot down the street and it connected to it no problem but it refuses to even acknowledge the fact that I have wifi at work...my laptop and and iphone are both connected, just the Nexus...
I've read os "similar" things happening to other people, but I would love to solve and know more about this if anyone has any info.
Thanks,
Lou
EDIT
I played around some more, and solved the problem.
I went to settings - wireless and networs - wifi settings - then the menu button, and went to advanced settings.
From here I went to regulatory domain and forced 14 channels and it seems to work now.
Hope this helps someone
L
Seems like they removed that option in the patch.
Cant find it anymore and my WiFi is not really working as it should any longer.. I get a connection speed of only 5mbps sitting very close to my AP. :-/
since update, my wifi is very fidgity. loses my house wifi all the time now. seems like every time the phone goes to sleep. my router is the schizz, so it shouldn't be because of lack of signal.

[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.

I do not have the issue, but maybe you can try this.
1. Open phone dialer (Phone App)
2. Dial *#0011#
3. The ServiceMode screen will be open. When it is open. Tap on menu button on top right.
4. Select "WiFi"
5. Find "WiFi Power Save Mode"
6. Press the "ON" button to turn the "WiFi Power Save Mode" off. (It will show as "OFF" if it is off)
7. Your WiFi will be off and on again.
8. Try to reconnect to the Wifi.

You haven't got smart network switch turned on? (under WiFI settings) it'll do that if it thinks you WiFI connection isn't stable.

Set Google public DNS in your router
Ok i just found out its only doing it at home, i tried wifi and my work and it works perfectly doesnt disconnect and connect, but at home it does, though it never did it before and i didnt change or do anything to my router or my phone which i find very strange.
thanks for the help guys i appreciate it a lot, does anyone know what i can do?
have you found a fix to this yet? I'm having the same issue and getting ready to just return the phone and buy something else. My home network is fine, the other tablets, phones, laptops are having 0 issues, Yet my GS5 is either dropping or something, it seems to run horrible slow and things just time out.

No, and the reason that we don't know is that you didn't provide any useful details about your situation.
If you think that someone can do more than make a random guess implies that you think that there are only one or two possible causes. But most issues, including this one, have hundreds of possible causes. So random guesses are not terribly useful. Nor are we psychic, so the only way to efficiently narrow it down is to look for anomolies in your configuration. Which you haven't described.
You should be providing as much technical detail as possible, e.g. what is your home router model & it's firmware version and configuration details, phone firmware version, any specific error messages, any observed pattern, a logcat if you can and anything else that seems relevant.

Have you tried changing the channel on your router?
Sent from my Nexus 7 using Tapatalk
Change the router channel
Change the router SSID
Default the router comfiguration
Change the router operating mode
Update the router firmware
Move the router to a different location
Use a different router
Unplug your neighbours new 50,000 watt pirate radio station
Update your phone firmware
Buy a different phone
Sacrifice a piece of triple chocolate gnocche cake to the pagan God of chocolate and wifi
All random guesses with roughly equivalent (and small) chances of success.
Or one could try troubleshooting the issue methodically.

Hey guys,
I had this problem before, This is an issue with your samsung device and your ISP. They aren't compatible with each other.
Solution:
You must just block clients3.google.com in your modem/router. You can use Block Web Sites section in your modem/router.
Every thing has a solution.
Enjoy your device WIFI.

I have teh same issue on my S5 Cricket. The WIFI does NOT disconnect. Its connected however I don't have internet connection. Turning the WIFI on and OFF fixes the issue, for a short while until it happens again in an hour. Sometimes I slick on a link and wait and wait just to find out the darn WIFI is not connected to the internet. (probably not even connected to my router properly eg, I cant see my laptop shared drives for example).
This has something to do with saving battery or somthing. WIFI internals shut down, even though the icon on top of the screen still shows I'm connected.

Your phone thinks that your WiFi is unstable and dumps the connection to go back to 4g. Why exactly, who knows, but it's easy to turn off the "smart" network switch. Simply hold down the WiFi icon for 2 seconds to get into the connections section. Right there at the top is the smart network switch section ... just uncheck the selection box. Easy.
Lastly, people like fffft need to get over themselves. The fix for the original poster's question was easy, but since fffft didn't know it, he decided to instead attack in order to make himself feel superior. How sad and pathetic does someone have to be to troll forums looking for opportunities to attack and belittle someone else?

The issue is resolved simply by going to the advanced settings in Wifi and disabling 'Always allow scanning'.
Hope this helps.

I had the same issue. I just tried the suggestion, turning of smart network switch in the wifi-advanced menu. Seems to be working so far!
Thanks!
Well I know that Smart Network is turning off wifi.. problem is that i have a fiber at home!! So what kind of problem smart network finds on my broadband?? ?
solution to wifi disconnect problem
I was looking for an answer to a different wi-fi question when I saw this.
I'm on AT&T with my S5.
Under the Wi-Fi settings I have an option for "Smart Network Switch" which says it Automatically switches between Wi-Fi and mobile networks to maintain a stable internet connection. Anytime a computer says it automatically does something for me; I typically say no thanks. I don't typically like my devices making assumptions of what I like, don't like or want to do. So I have that option unchecked. I never have an issue with the network stability once I've connected to a specific wi-fi connection.
Not sure if that will help you all or not. But thought I'd share.
so under Settings --> Quick Settings --> Wi-Fi you will find a check box option named "Smart network switch", untick it, this should take care of the problem.

Same problem
Hi, I have the same problem. Here some info:
- Device: Samsung Galaxy S5 (SM-G900F), Stock, not rooted
- Android version: 5.0
- Kernel version: 3.4.0-5640614 (2015-09-01)
- 'Smart network switch' is turned off
- 'Always allow scanning' is disabled
The problem started 2-3 days ago. When I turn on WiFi/WLAN the phone constantly turns it back off and on again. Didn't happen before, didn't change anything on the router (I have no access to it ) and didn't install a new app (as far as I can remember). I don't know if it only happens on this access point.
I made a log file (adb logcat) but am not sure if it contains sensitive information, is it save to share online?
The logcat doesn't contain any sensitive passwords.

I'm have the exact same problem.
Samsung Galaxy S5 (SM-G900T)
CyanogenMod (13.0-20151203)
Android 6.0 (Marshmallow)
Baseband (G900TUVU1ANE6)
Smart network switch: disabled
Always allow scanning: disabled
What's happening is as soon as my Wi-Fi finishes authenticating and connects, it is immediately disconnected and tries again. No other devices in my house are having any issues, so that eliminates the router. When I factory reset my phone the Wi-Fi begins to work again, so that eliminates my phones hardware. The confusing part is that I installed a bunch of apps such as AdGuard that could possibly cause an issue but everything worked and this started out of nowhere. Also, I factory reset my phone AGAIN and AGAIN, everything worked and out of nowhere while I was looking at my screen while idling, I watched as the Wi-Fi connection dropped and began the disconnect/reconnect loop...
I'm assuming it has to be a software issue because it only started when I updated to a newer Cyanogen. I'm about to test if other Wi-Fi networks have this problem and I'm also going to look through and post a log.
If anyone has any questions or suggestions that may lead to a fix, PLEASE help!
Thanks
Well I factory reset again, this time wiping the internal storage and everything is now fine. I did look at my logcat and there were Wi-Fi errors but I forgot to post them...

Wi-fi and Bluetooth turn on and off randomly

Hey
I am guessing this is a software/app/os issue, but it is noticeable on the LG V20 thanks to the second screen.
Recently I have noticed that wifi and bt turn on while the main screen is off. When I turn the screen on, they both turn off like naughty school kids caught smoking. This is obviously when I am not using wifi or bt.
I have scoured the settings looking for something that can stop this from happening, but nothing so far. Wifi has a setting where it says, "keep wifi on while in standby", with three options, I have tried all three of them, and nothing is preventing this from happening.
I enjoy controlling these functions, and get anxious when it happens automatically. Anyone with advice?
I think I have found the solution. I had the app Firechat installed which uses Bluetooth and WiFi to transmit data to other devices. I have uninstalled it now and it seems that WiFi and bt have stopped turning on automatically.

Anyone else? My wifi will shut off after about 30 seconds and I have those same settings set to keep on. I even tried after a factory reset and still having this issue.
I have the same problem,if the Bluetooth is on I have high latency wifi and conectivity loss, this only fix if I power off the bluetooth

I am also running into this issue. The only way I can get my wifi to connect to my home router is by restarting my phone. Otherwise the rest of the time, I see a message stating that my wifi is disconnected, when it clearly was not, it was even showing me nearby routers that I could connect to, but not my own router, even when i tried to add my router manually, it could not connect. I am having the same issue with Bluetooth connections. My laptop can sometimes see my phones Bluetooth, but my car can't find it at all. I'm on AT&T H910, running on DESOLATION 7.1.2

No Wifi after 10 mins

I have seen lots of issues concerning wifi but I haven't seen a thread with the same issues I have been experiencing.
When I turn on the phone I see all the local wifi networks and I can successfully connect to them. After a period of time (appears to be random) I lose connection. When I go to the wifi settings I don't see any of the local networks. In fact I can stand next to the router and it won't show up in the list of networks.
I have tried turning the wifi on/off but that doesn't have any affect. The only solution is to restart my phone i.e. rinse and repeat.
I have factory-reset my phone and didn't install from backup but that hasn't made any difference.
Has anyone seen this behaviour and do they have a solution?
Brother wish I knew why the wifi was such a mess but I can't get any answers either.
Same here, after endless search no wifi is found. Connection comes after restart only for minutes, but not always.

Have you experienced this when connected to other access points/routers?
Try turning off "turn on wifi automatically" (just suggestion)
select another channel on your router
Is the network you are having trouble with "hidden"?
"find somebody that you think is undeserving of your compassion and give it to them" - Christian Picciolini
Thanks for the responses. I was having issues accessing public wifis and my own private one (not hidden). I changed channel on the router with no success.
I reached out to Essential and they were very helpful and have subsequently replaced the phone.
Mine is a bit curious, sometimes after reboot it shows no sim-card and switches after seconds wifi off.
Could it be a faulty antenna or something? At the moment it works normal.
