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 connecting... saved... obtaining ip address... saved

I'm wondering if anyone running either cm 10 or Pac roms is having issues after a few weeks, of wifi attempting to connect then saying saved and doing that over and over again and not connecting. I know other people not necessarily using this phone have had this issue before but, I can't seem to find any solutions to the problem. I am currently running Pac all in one Rom and it was working great until today but, I have had these issues on cm 10 before and the only thing that seems to fix is to flash a new Rom and I like this one and don't want to re-flash.

Mine was doing that but a dirty flash fixed it and I still have all my settings.

I always get this issue on custom ROMs
Sent from my MB886 using xda premium

I've been having this issue as well, again and again.. I've had about a 50/50 success rate with dirty flashing. Anyway, I believe the problem has something to do with the dhcp assigned ip addresses from the router. It's something on the phone side of it because changing dhcp settings,lease times etc., on the router have no effect. When you lose WiFi and it goes into that loop and won't connect, go into WiFi settings, and forget your network. Then select your network again and enable the advanced settings. Change from dhcp to static and then assign yourself a local IP. I have a Linksys router so I entered 192.168.1.8 . so I believe a netgear router would be 192.168.2.?? , the ?? or 8 being whatever is unused on your network. If you haven't already, enter your password and connect. I connected immediately after that. I understand this isn't really a "fix" because won't help you when trying to connect to networks that you can't assign your own IP, like say Starbucks or somewhere.. But hopefully this may point someone who knows more about this stuff in the right direction to actually fix whatever is off in the phone. Drivers maybe? Hope this helps!

Thank you for the explanation I tried a dirty flash and that solves it for about 12 hours. I am getting faster at flashing and restoring everything and am now flashing a new Rom every couple of days so it's not that big of a deal I'll just take it as a sign I should try a new Rom I'm now running the unofficial aokp Rom and I'm liking it next time it happens I'll just try another. Thanks for all the help glad to know the issue isn't because I've done something wrong.

Is there anyway to fix this issue yet?

@TTLayland said exactly what I'd say...static IP. I'll add the the Devs are working on updated WiFi drivers for the kernel. When that's ready hopefully that'll work for ya'll. I haven't had any WiFi issues for the past few weeks. Connected to my House, McD's, and the hospital.
Post the actual make & model of your router and I/we'll see what can be found for it.
Also, try setting the phone to 2.4 Ghz only...my old router was 2.4ghz and the auto setting would randomly kick me. New router broadcasts in both 5ghz and 2.4ghz, I connect to the 5ghz one and use auto without issue.

a lot of the times I have to log into my router and turn the security completely off and then log on with my phone get a connection and then log back into my router turn the security back on and then I'm good to go.
Kinda like the flashing back to ICS to get a GPS lock to work on custom jb ROM's

Ok, I didn't realize Devs were working on it. I have statics set for my home, but being a Network Admin I travel to many different networks and because of the way our network transverses settinig an ip is not an option as the same SSID is used for about 95 different sites. So DHCP is a must.
I just thought it was strange that the Carbon rom I am using was working for about 2 weeks correctly then stopped connecting, sometimes a reboot will get it to connect.
Thanks.

I wish it would work I just gave up on wifi on ahd if using custom rom

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.

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?

Mine does the same thing, but I use wifi when at home so I have not noticed. Maybe it is a network issue on their end. When i turn off wifi I get my 4G/LTE symbol on the top bar so it is working. I still get the same issue as you have pictured. I don't believe that is actually used by AT&T now. In either case even though it says failed mine still works so your issue lies elsewhere if it is not working.

Try a network reset from this thread. Can't hurt, may fix it, easy.

How do I do the network reset?
Sent from my SAMSUNG-SM-N900A using Tapatalk

Have you checked your APN settings? I would also try power cycling and if all else fails try contacting ATT. If you dont have any apns, search around and you should find them.

Tried all that. How do I reset network settings?

Well I guess lets go through the basics first...Are you sure that WiFi is on? Have you restarted your phone? Have you performed a factory reset?

Are the ssid's your searching for "hidden" ssid's?
If I set my home Wi-Fi router to broadcast ssid, I see it. If I set it to hidden, I can't see it.

This is a known problem. I have it; I thought it was my fault for deleting too many apk's. Then a girl came along with unrooted stock phone and said she had it.
use app from play store to temporarily fix problem

My Note 3 drops WiFi at my home saying the signal its not strong, but my computer and the other phones can connect. I have to turn off cellular data to get it to connect.
