Hi guys.
first my wifi became unreliable, it disconnected, didn´t reconnect sometimes etc...
now, it´s not working anymore at all.
when i go to wi-fi settings it says turning on, then the red arrow appears, then immediately it says turning off. down there comes a message "unable to scan for networks"
i searched the whole forum, but didn´t find a simlar problem.
i reseted it to factory, didn´t help.
it can´t be a router problem, ´cause all the other devices on the wifi work, even my friends myt4G.
any tricks or ideas anyone?
i got this form a friend in the states, bought last december, he ment, in the US they have mostly only 90 days warranty, in germany we got 2 years.. is this true..?
stock rom. 2.3
Try chaning the channel on your Wifi Router. Most of the new routers you can go to routerlogin.net from a computer that is connected to the router and change the settings. I had the same problem and it appeared all of my neighbors were using the same channels i was. I move to a different one and haven't had a problem since. It will not affect the SSID or the password So all of your login it stuff will stay the same. Any WAN connected device just might lose signal for a second or two while the router changes channels.
thx. channel was on auto. changed it to 11 out of 13. didn´t help. also, i have only 3 wifis in my neighbourhood, i can get with my pc. on the htc, it shows only mine + the direct neighbour..
it seems that wasn´t he prob here...
could it be a hardwareprob? anyone any knowhow on american warranty?
the wi-fi button is almost not responding anymore.. when i turn it off, it turns itself on again, when i go into wifi settings, ist keeps truning on and off again in an endless loop....
edit: tethering does also not work anymore. when i click on portable wif hotspot, it says error...
hardwarefailure?
i found these guys who have the same problems.

seems to be a gingerbreadissue... perhaps i´ll try downgrading first.
so i downgraded to 2.2.1 and it worked. got to bed, woke up, not working anymore "unable to scan for networks" again
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.

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.

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.

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.

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...
Hi all, as noted in subject, occasionally I am connected to WiFi but I get no active connection (nothing comes in or goes out). The only way I remedy this is disabling/enabling WiFi and as this is a small annoyance, any reason this happens? I have an RT-66U router as well, if it matters.
Thanks and happy holidays.
Nobody?
Hi
could you solve it already?
if not, switch location settings to GPS ONLY.
good luck

Yeah I'm having the same problem except even when disabling/enabling wifi, I can't get a reliable active connection. It's only when I turn on airplane mode and off and reconnect. Then will I get a reliable internet connection. I'm not sure what's going on. The strangest thing is this problem occurred over time. First month, no problem. 2nd months, occasionally. now, into the 3rd, it's on a daily basis. My previous Verizon Note 2 also had this issue but then seemingly disappeared, only to rear it's ugly head a few months down the road.
Here's a post on reddit with others having the same issue: http://www.reddit.com/r/galaxynote4/comments/2ks0ap/note_4_wifi_issue/
Not sure if a custom rom would solve it. For now I'm just using my 4G connection as I have the unlimited plan.
turn smart switch off and see if it helps. does it get an ip address ?
Have you rebooted the router? Unplug it, wait a few seconds, then plug it in again. My router does this every now and then.
Also try rebooting your phone.
If neither one of those work, then you can try factory resetting your phone as a last resort. After that, if it's still not working then either your phone or router is busted.
Ever since I connected my galaxy s8 to the router my WiFi is having problems. First every time I try to download something from the play store it takes ages ( not to talk about the system update I downloaded) it gets stuck at 128 kbs then up to 5mbs then stuck again while it works everywhere else in the house. Second, I've been getting an exclamation mark next to the WiFi sign on my galaxy s8,every time that happens I don't have WiFi on my phone AND everywhere else for like 5 minutes or more it's usually happening when I try to download something. I don't know why it's happening but it's really frustrating honestly. I once came back home and decided to leave WiFi off on the phone and everything worked just fine untill I turned it on again in the evening... It's really weird. I thought its because of my router so I decided to switch to another router which is coming tomorrow. I hope it won't happen on the new router but could you guys help me to figure why this happening to me and maybe fix it? Thank you.

That is really weird. I only get the exclamation when I am connected to wifi but need to supply a login for it like a public wifi that makes you go to a webpage and sign in. I have a G6, but figured I'd chime with my experience in the hope it helps you out.

Yeah I know what you mean xD I'd have that too in public WiFi but in home when I have that exclamation mark it says " Internet connection may not be accessible" or something like that under my WiFi name in Internet settings.

That is strange. Honestly, it sounds like an issue with your ISP or modem/router.
I would get the exclamation when the signal got too weak, especially on 5ghz wifi which my unit had terrible reception for. Also I noticed that holding the phone by the top (my left hand in landscape orientation) would really kill the 5ghz reception and cause the exclamation to pop up and wifi lost.
I would start with login into router and make sure it's updated to latest FW and is set to auto update. Then I would check other settings, for example you may be over the limit for maximum connected devices.
Just to chime in, I have the same problem on my S8. I'll be connected to wifi and after 10-15 minutes I'll notice I'm getting no notifications and will see that the wifi icon has the "!" next to it. The wifi also disconnects when the screen is off, which appears to be a very common bug. I'll notice about 15 seconds after I turn the screen on that I get the message "Your phone is connected to xxxx wifi" or whatever it says. I use a sonos speaker as my alarm clock in the morning, so I have to sit there and wait to connect to wifi before I can turn off the music. It is terribly annoying.
I was having this same issue. I have the VZW S8+. After upgrading to new system update AQDF, I have not had the wifi "!" issue anymore. I cleaned system cache after the upgrade.
S8+ here. I get the exclamation point and disconnectivity randomly at home. Disabling and reenabling wifi works, but it's really annoying...
I was experiencing this maybe 3-4 weeks ago but my wifi has never been the best so I assumed that was the issue. I cleared the cache, reset router, forgot & reconnected to wifi, none of which helped but in time it's disappeared. Wish I could be of more help.

On the s8, this is what the ! Is intended for. When your signal is too low, it will stop it until it is good enough quality. Deemed by whatever dbm Samsung has set. It only disconnects when smart network switch is turned on. When it is turned off, you will still get the ! Which is just saying that the connection is not favorable and will be slow, so you should move closer to the router
Sent from my Samsung SM-G950U using XDA Labs
Only time I get the ! is when my home broadband drops out which thanks to Virgin is quiet often lately. Sometimes however, it still works even with the ! showing.
Unlocked S8 owner and i have the exact same problem. Getting the exclamation mark next to wifi symbol and internet connection get lost or brcome extreme slow. It is not the issue of the distance from the router...
Where can I clean the system cache ? without loose my settings or program?

I have the same problem with my office router. The signal quality is excellent but the exclamation mark ( ! ) does appear sometimes. It does not happen daily as some days the luck appears to be good but sometimes its really frustating as the mark keeps showing on Wifi and it does not work. As stated by other member above all other devices works perfectly fine. I am using TP Link 54M Wireless Router, Model No.: TL-WR340G/TL-WR340GD. Please advise.

I have the same issue from time to time. in my home I have a mesh wifi system and I notice that in 1 room in particular where the signal drops from 702 mgps to 234 mgps I get the exclamation point and can't use wifi at all. have to turn it off and use lte instead. this also happens from time to time on the strong signal. At work the wifi is at 52 mgps and I never have issues with the exclamation point and wifi not available message. the other people in my home do not have the same issue with their phones so this is definitely a Samsung issue. I have a feeling will either need to get a different phone or return it for a different manufacturer. Any ideas on a fix for this without either of those solutions?
For my s8+ Solved
I was having wifi exclamation mark on my s8+
I solved this issue with changing the wireless security settings on my router
Change :
Version : WPA2-PSK
Encryption : AES
#And also wipe cache partition of your phone#
It's working on my s8+ and now internet work perfectly without exclamation mark or disconnecting
Go to your settings, connections, mobile networks, access point names. Click the three dots upper right and select reset to default. Restart your phone. The exclamation will not return when on wifi.
