try and add the network manually (as if the SSID wasn't being broadcast) see if that works, i had a similar problem and did this and it kicked the wifi in the seat of the pants and it started working again.

Tried that, still not finding it. Would the security level / type of security have any thing to do with it?

Try going into settings /wireless settings then hit wifi settings from there hit menu then hit advance and change the channel to 14 I think its 11 by default hope it helps good luck

same thing happened to me. what I did was...I made my phone "forget" my home network then refreshed it and it found my home network and I reconnected. haven't had a problem since.

Wifi disconnecting problems..

Is anyone getting the wifi problems that the other versions of the Note 3 are getting? Preferably when it says the network was disconnected for being too slow or something like that? I know it happens on the T-Mobile, Verizon, and International versions.

Mine doesn't disconnect but it says wifi signal is unstable, then I looked in settings when this happens and it says wifi signal strength VERY STRONG, I'm sitting 10' from my router and I know damn well the the signal is strong as it says 72mbps. Lots of issues with wifi signals are popping up in the N3 sections, not good.

Yep, same as Quickvic30

Go to wifi advanced settings and uncheck Auto Network Switch. It appears the phone will "test" the speed of the wifi network to your 4g and picks which is faster.

thats not always the cure. but in the international section of the forums. looks like there was 2 OTAS and one has fixed the wifi issue. so it will come eventually

Thanks for the replies.

Hey all,
I realized that the wireless issues were all where there are at least access points broadcasting the same network. The signal indicator flickers back and forth between solid and weak, and I think the wireless manager is jumping back and forth instead of sticking with the stronger one. I installed one"WiFi Manager" from Play store and the connection is more solid. I haven't rooted my device yet, so this may be the best answer until a patch shows up.
Let me know if it works,

Hello I was having this problem I had to remove my ad stop program and everything starting working normal again adblockplus to be exact but that fixed issues with mms messages and the wifi.

Yes- nothing but problems with wifi dropping and reporting as slow/unstable. Rooted on AT&T MI1. Various AP's, not specific to any one location. Basically renders wifi useless.

I've been noticing WiFi drops also

Yall- this issue has been bugging the hell out of me. Finally tried something I found buried in a few other forums that immediately fixed the spotty connect/disconnect and wifi data stalling errors.
Enter into the service configuration mode by dialing *#0011# and hit the menu key- touch "wifi" and turn off "wifi power saving". Reboot. After having tried everything else I was skeptical but I can confirm (in my case) it worked like a charm!
Hope it helps someone else.

Great info! I just did it and rebooted so I will report back with the results. Thanks!!!

Another possible fix for you guys.. go into wifi in settings..hit menu then click advanced. Inside advanced make sure to uncheck auto network switch. Reboot and voila.

I've been using that method for most of the day, and I've noticed some good results with WiFi. Unsure how it's going to affect battery life yet though lol

auto-network switch
I didn't have to reboot, but disabling the auto network switch did help. I kept getting the 'unstable messages', and I finally had to click the "don't show this again" button and hit 'cancel' so that the OS would stop trying to help my be re-enabling the auto network switch. So, the question is, is this just #LTE2fastprobs, or are there real wireless n/ac issues that make this phone less than desirable?

(Q) Browser Bar Off?

I accidently turned off my browser bar when a pop-up intruded an email I was typing. I have no idea what the browser bar setting is but I cannot connect to any wifi network now. So I open up settings and clicked on the browser bar tab and it fc's settings every time. I tried a reboot, and clearing cache in recovery but it still won't let me turn the browser bar on. Any ideas here?
Not that I was at all impressed with the wifi capabilities on this device. My connectivity has been nothing short of pathetic and I've followed every rumored fix to no avail. I think I'm ready to try a factory data reset before my 14 days are up.
Again, any help is appreciated.

Exact same issue here.

This phone has the best WiFi I have had with any phone. There is a dead spot at my work wifi that all phones I have had would lose connection. So far, I have yet to lose connection with my 3 there.

It's very strange that the browser bar would have any effect on wifi connectivity to begin with. I've had it disabled for a while and haven't had any wifi problems.
Samsung has a bunch of performance/bug issues they seriously need to iron out. It's almost like they don't beta test these devices before they churn them out.

For some reason I cannot connect to my WiFi, I have the correct password but it's not working.

Try to remove the settings.
Go to WiFi. tap the wifi your trying to connect to, select Forget.
Then try to re-enter the password.
If that fails try to restart router.
If that fails we will need more info.

Nothing is working, my sister has an iPhone and it works but for me it is stuck at authenticating then says disconnected because of poor connection but my router is right next to me.

I had this issue last week and was caused by the app Tasker. Are you using Tasker for any profile involving wifi?

I am using tasker but I don't think for any WiFi applications I will check and get back to you.
Sent from my HTC One using xda app-developers app

Do you by any chance have fast boot enabled?
If so disable that, power cycle the phone. Remove the current WiFI info by selecting Forget (from my original post) and then try it..
You can find the fastboot option under Settings > Power

Were there any changes to the wifi with KitKat?
I'm unable to connect to my home network. I get the "wifi is unavailable" notification and in the list the networks is "out of range" although the signal is excellent.
I've tried everything.
Changing channels, resetting the router, factory reset to my phone, changing various wifi parameters, trying to set a static IP.
I'm frustrated as I cannot connect to my own wifi, whereas I didn't have any problems prior to the update.

might worth a try disabling tasker and rebooting. Tasker seems to have issue with the M7 for some users. Every times I use tasker, I'm having this exact same issue with my wifi.

Fast boot isn't on and my tasker doesn't have any WiFi tasks.I'll try forgetting network again but I've done it a dozen times.

[Q] WiFi issue.

Alright, here's the problem. I can connect to my WiFi at work. I get full bars. But it won't pull any data. Nothing loads in any app or browser. It's only here that it happens and I'm the only one with any problems. I've read everything I can find and tried many things (WiFi "fixer" apps (both root and non-root), switching IPs, forgetting the network and setting it up from scratch) to no avail. I've spoken with our network administrator to ask him if he'd blocked any IPs or anything and he assured me that he had not (he doesn't even have the administrative passwords and can't reset the router as it is stuck to the ceiling 50 feet in the air).
So wtf? Anybody have any suggestions outside of a factory reset? I'm all ears. Thanks in advance (I'll also spank your Thanks Button )
Edit: Also, I've been on this network for years. This happened out of nowhere last week and I'm getting frustrated.

AT&T Smart Wi-Fi connection manager is a free app that finds and auto-connects to available hotspots, maximizes battery life by only turning Wi-Fi on & off when needed, logs missed hotspot opportunities for your review and action for subsequent use, and displays your real-time cellular and Wi-Fi data usage.

I can't find the thread where this tip came from at the moment but this is what I remembered. It shouldn't be hard to search thru the forums. It may or may not fix your issue but give it a try anymore. It won't break anything. GL
1. at your dial pad enter *#0011#, this will take you to the SERVICE MODE
2. press the "menu" - the soft key on the left side of home button
3. select "WiFi"
3. toggle the ON/OFF switch to turn off the wifi power save mode.
4. press home button to exit

I've seen android devices fail to resolve domain names on corporate networks. Check if you can ping outside IP addresses and such - if so, there's probably a way to force it to use google public DNS, though of course this won't resolve intranet names...
(Also, before you exert too much effort on this, make sure your corporate wifi is worth connecting to. Some wifi networks in offices are crap...).

Maybe I'm just spoiled by living in a place with excellent 4G LTE coverage, but I don't see any appeal in connecting to random hotspots - I've never connected to a hotspot that performed better than the 4G, and I don't come close to the data limits of my plan (This month I'll hit 1GB for the first time, I think, because our connection at home was out yesterday, and I had to tether for me and roommate who work from home). Plus good deal of the hotspots I tried (before I realized this was silly) didn't even have internet behind them. The majority of the attwifi ones around here (in red cambridge, ma) don't work - on default settings, I'd just be walking along, and bam - no connectivity, what happened? Oh, it autoconnected to an attwifi hotspot that didn't have any internet connectivity.

I turned the WiFi power saving mode off. I'll report back once I get back to work and check the results.
