WiFi randomly enabling itself

In the morning before I go to work I usually disable WiFi as I don't use it at work and would like to save a little battery. However, I've noticed that throughout the day, I'll check a notification and see that WiFi has turned on without me turning it on myself. I can't see any pattern or correlation that would match up with this. Does anyone know what would cause this? I factory reset last night (due to an unrelated issue) and it's still occurring. I only have a couple of extra apps installed, Falcon Pro and reddit sync.

i think power saving mode sometimes enables wifi when its available... not sure how often this happens or if thats even the issue you're having but check the power save mode settings... 3g and 4g use more power than wifi

I don't have the power saving settings enabled, and I don't see any setting that resembles that kind of behaviour.

So at some point while I was driving home from work WiFi enabled itself again (I didn't even touch the phone). I'm wondering if it may be S Beam causing it? I haven't actually used it but it's the only thing I can think of that would need to actually turn WiFi on. I may try turning it off tomorrow morning when I turn WiFi off and see if that stops WiFi from randomly enabling.

Galaxy S4 Wifi auto enable
Is there a resolution for this? I heard that on the S3 it would pay attention to what cell towers you are using and if it recognizes you are in an area where you have used wifi before it will enable and connect. This seems to be the symptom that I am seeing and it's bad for me. It keeps trying to connect to my work network because occationally I log on so I can access materials. but when I want to listen to Slacker Radio I can't because it's blocked. This is a cronic problem for my phone and I'm not able to find out how to disable it.

if you have got any battery saving apps delete them

WiFi hangs and drops

Hi
I'm currently having a problem with my S4 that is driving me mad.
Ever since I got the phone I've had a bit of a problem with the WiFi connection. I've flashed a few kernels and some seems to help the problem more than others but it's still there.
What happens is the phone connects to WiFi no problems. Then maybe after a few minutes of use the phone won't give me any data. If I search a Web page it just hangs and then says unable to display web page. I then have to knock the WiFi off and back and and it cures the problem temporarily.
Sometimes the WiFi connection can be fine and last a few hours without hanging. Other times it can last a few minutes. The WiFi icon always remains on the screen and the arrows act as if data is getting processed but nothing ever happens. The odd time it will also kick itself off the WiFi and reconnect.
It's driving me mad having to constantly knock it on and off. I'm missing WhatsApp messages for hours because of it also.
Is it a common problem? If not the phone
is still under warranty so I will have to send it back but then that's me phone less for god knows how long
Any help would be great.

if you are rooted, flash this http://www.adrive.com/public/8DJWtV/WifiFix.zip
its a fix that sorted out my wifi problems

I think you should revert back to the latest stock and reset your modem. There might be some fancy settings in your modem software that need to be turned off. I read that somewhere but can't remember which ones. Just search on here.:cyclops:

Hi guys, sorry I've just seen the replies and thank you for taking the time
I shall have a blast at both your solutions and report back.
Thank you again

Well I tried the WiFi fix but that hasn't cured my problem. Today I will flash to stock rom and then re-root and see if that makes a difference. If not its off for repair under warranty and the old Nokia 8210 will be coming out of retirement for a few days lol

May be a fix?
1) type *#0011#

Hi jehbrian.
I've never heard of this fix but I'm willing to give it a go (whats the worst that can happen lol).
Done the above and indeed you get to a point where Wifi power saving mode is on. I've knocked it off and will see how I get on in the next couple of days. It does make sense that the power saving mode could be killing the Wifi every now and again.
Thanks for the tip and have a pleasant day :fingers-crossed:

I had tried that one. It spends about 10% more battery.

Does it?
Surely there must be something else that can compensate for this loss if it means the Wifi actually works. GPS? Bluetooth? Screen brightness?
My phone is on my dock so can't verify the loss of battery.

I've never noticed the battery drain... besides, S4's battery life is bad anyway.

Internet connection unstable notification

Is anyone else seeing the Internet Connection Unstable notification frequently? I'm getting it at home and at work, on 802.11n and .11ac. At home the connection is not unstable, new RT-AC66U router (standing next to a PC getting full 1.3gb connection). Have a Note 2 that I never saw this notification once on. Also have never seen this notifcation on my work network with the Note 2, and have with the 3. It also seems to pop up that message even when I have 3 or 4 bars on the connection.
I saw another post about weak cell signal on someone's 3. Anyone else experiencing these notifications regularly, when they should have a strong connection? Should I try to get my phone replaced?
Thanks!

I have seen it while walking around outside, close to the end of Wi-Fi range.... I am not sure the Note 2 had this notification at all, which could be why you haven't seen it before.

I get it. Its annoying. Hopefully some mod will get rid of it soon

Hm. Well that's promising that it's not my particular phone - and that it may not have existed in android 4.1.x on the Note 2.

I contacted Samsung and they had me perform a cache reset that seems to have cleared up the intermittent unstable internet connection issues;
-Power the device off (remove and re-insert the battery).
-Press and hold the Volume Up key and the Home key, then press and hold the Power key.
-When the device vibrates; release only the Power key while still holding the other two keys.
-When the Android system recovery menu displays; release the Volume Up and the Home key.
-Navigate with the Volume keys to the "wipe cache partition" option and press the Power key to select.
-Wait for the cache is cleared. While reboot system now is highlighted, press the Power key and reboot the device.
Hopefully this works for you as well.

I had the same problems last couple days with this same issue. Today I used HTC one and left note 3 on desk off all day and back on note and Wi-Fi tonight and no issues at all flawless. Don't know if having it off all day helped or something but hope it doesn't come back lol

I've also been getting this. It's definitely the handset and NOT the WiFi as it happens at my home as well as my parent's home (both of which NEVER had any signal/droppage).

The notification was driving me crazy! The only way I was able to temporarily get rid of it is by disabling mobile data while connected to WiFi. For obvious reasons, that could hardly be considered a solution. Accessing the service menu (*#0011#), turning off WiFi power save mode, and rebooting didn't help, so I was planning to return this amazing device.
However, tpaquette, after trying your solution, everything seems to be resolved! Wiping the cache partition did the trick!
Just wanted to report that and say thanks.

The cache clear was a very temporary fix for us. Worked for part of the day. We have been a 5 iphone family for 6 years now and were all switching to the note 3. We already upgraded 2 but these are going back and we will have iphones again. Maybe next year with the Note 3.

I'm on the other side of this coin... for the past 2 years I've had several devices here at home and they all have worked OK with my home wifi... but with this Note3 I get the unstable notification several times a day... After doing some serious monitoring of my Internet connection I've found out my Internet actually IS unstable and the Note3 is advanced enough to let me know about it... what seems to be happening is my upload speed drops down to, or almost to, zero now and then and that's when the notification pops up... and i appreciate that because it's let me know I have a problem and helped me track it down.
so... that being said... Thank you Note3 for showing me my problem ... BUT ... would be nice to have the option to turn off the notification now that I know what is happening while I decide on what to do for a fix or maybe decide to just ride with it for awhile until I switch to another provider.
Note: it's not your device glitching in that causes this... it's your internet... and your other devices don't have the feature that let's you know you lost your up/down link for a few seconds... seems kinda sensitive though because under most circumstances, small glitches like this that go unnoticed aren't a problem anyway... that's why we have buffering.

No that is not the case when all of my other wireless devices like our remaining iPhones, laptops, DVR, Smart TV stream online content without issue. I can stream on any of these devices from across the house without receiving the first buffer message, yet the Note 3 will give unstable network messages and buffer multiple times while standing in the same room as the router. If this is a case of advanced features on the Note 3, its the Note 3 detecting its own poor WiFi performance.

Here's my Internet speed on my N3 and get that message also. Mostly while I'm recording a HD move or downloading a on demand movie for my direct tv. Also when streaming Netflix to my ps3.

I haven't had this issue but I cant help but wonder if there is some commonality between the router settings.
I'd first do two things, change thd channel of my router and give my device a static dsn and see where that gets me.
Then I'd play with my a/b/g/n output and ghz settinngs to see what it likes best.
If you are getting strong download speeds with an unstable connection it would seem to point to chatter or interference on the ghz spectrum. In example a motherboard or cordless phone placed too closly to the router will cause some interference. And ofcourse our samsungs which use newer 802.11ac can be pretty picky/confused with the input.
Heres a bit of reading. http://www.anadigics.com/news/press...owered_anadigics_wifi_and_cellular_solutionsI

It seems the Note 3 more thoroughly monitors your Wifi connectivity such as latency. I know when I peg out my internet connection downloading something on another device and the latency increases as a result the Note 3 will pop up that notification. No big deal since it's just informational and can be ignored.

I get that almost every time I walk from my barn to my house. In that fringe area where it's detecting the wifi signal and locks in it doesn't seem to like the signal fluctuations. I disregard the alert and everything is fine. I think Samsung needs to increase the time before it complains about poor signal lock, or just not ***** at all!

If you turn off your mobile data, the WiFi notifications stop. So it can't be anything to do with the WiFi signal. I think that there are apps that try to use the mobile data, and when they can't, throw out those notifications.

That's unfortunate. I'm surprised that solution only helped your situation temporarily as it has completely fixed the problem for many others, myself included. Anyone else tried it, only to have the notification come back?
Also, I cringe at the thought of you going back iPhones. I wouldn't wish that dreadful experience on my worst enemy.
Just thinking about it makes me nauseous...

Going to have to keep an eye on it because I'm pretty sure I had a few devices including the Note 3 on WIFI to download large 1GB+ apps and also when broadband drops out. Notifications seems to be accurate so far.

Note 2 wifi problem: Please Help.

My wifi was working very well. One day suddenly it went off. Initially I thought it was a connection problem, but eventually I discovered that the wifi toggle switch refused to start. It was stuck.
I did not upgrade or change anything (Currently running stock android 4.3.) In a bid to correct it I even did a factory reset. But wifi issue remained.
Did everything mentioned in various YouTube videos. But in vain.
The only way I can turn it on is by switching off the phone, removing the battery 4 a minute and restart. Wifi worked but to 5 to 10 min only.
Removing battery every time 2 start wifi is nuisance.
Pl advice.

I would advice you to do the following
=>Disable all power saver settings
=>Remove any battery saving App
If it doesn't work try
=>Installing the newest Official Firmware from Samsung(4.4),Download it from the sam mobile site
If that doesn't work well then i cant help you anymore
Hope that helps and hit the thanks if i helped

Dear Sammy,
I did exactly the same. Installed the 4.4.2 but a new problem has emerged. Wifi shows connected. I can also see the white wifi icon on status bar. But in fact is not connected. Can't open anything. Not even router configuration ip address.
To make sure it was not a modem/ router issue, I checked d connection on another phone. It was working perfectly.
Here too I tried switching off for couple of minutes but on start it just shows connected when it is actually not. (Confirmed several times on other phone)
Plz help.

Wi-Fi won't turn on after phone sleeps, sometimes

Hi!
My n9005 works perfectly fine, but SOMETIMES in standby when I wake the phone up, I notice Wi-Fi is turned off, while it previous it was on.
When I try to move the knob thing to turn on Wi-Fi it just does the animation and stays like it's trying to turn it on, but doesn't.
I have to restart the phone every time to make Wi-Fi work again.
This doesn't happen a lot of the time, but it's annoying.
Is this a common thing? What could I do to fix it?
Thank you for your time.

Open wifi menu and go to option.
then go to advanced, there is and option "keep wifi on during sleep". Make sure it says "always on"

The problem isn't that.
That's how it is by default.
I would be able to turn wifi on after it turned off if that was the problem.
In my case I need to restart the phone to be able to.

I did a factory reset and Odin flash of the same exact ROM that I had by downloading from Sammobile.
The problem is so random and seems to only happen when the phone sleeps or is charging. Sometimes it works for a few days, sometimes it will happen, no WiFi until a restart.
EDIT:
Maybe I should download another ROM from sammobile and try that?
Does that trip Knox?
I have a [Austria (T-Mobile) MAX] ROM (PDA:N9005XXUGBOK6
CSC:N9005MAXGBOK1) atm, I bought the Note 3 used and it had that. But I live in Serbia, maybe I should try the Serbian one in example for my carrier?
The WiFi problem is just annoying at most, it doesn't happen often, but I shouldn't have to restart the phone to have WiFi.

If I dont have to do that, please reply.

For anyone interested, I solved my problem on my own.

I didn't experience the same issue ever again.
