This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.
I have the same problem. Need help too.

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.
Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.
I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.
I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.
Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.
OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,
Thanks

I had this issue with my S3, but never with the Note 2. What i did in that instance was reinstall the OS and that seemed to have fixed the issue. Hope this helps!

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.
Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.
Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???
I need your help everyone. My brother is using the Galaxy S II running ICS 4.0.1 that was bought along with my S III and it is acting up. GSII is running stock ICS, and still in stock configuration. Phone is not rooted or messed with in any manner. The phone connects and stays connected to the Home Network, but data transfer stops after few seconds. All the other devices at home (laptops, PC, other phones) stay connected and works fine. Home network is through Century link and wireless is through actiontec modem and wifi router - http://www.actiontec.com/products/product.php?pid=264#.UOyOPB3aI7s). He has been using this phone with no problems with the same wireless network for almost 4 months and this issue started almost a month ago. I have no idea why it went wrong all of a sudden and not had any luck in finding a solution from all my research.
Problem: When WiFi is activated, it will connect to the home wireless network and will work for few seconds. As soon as background activity that requires data stops, the WiFi stops working. If I am browsing or a video is playing on Youtube, it will stay connected, but as soon as I exit out of the application that is pulling data, it stops working. I have to turn it off and back on again for it to work, but this issue repeats. From looking at the signal bars for WiFi, its full (I was sitting next the router) upload arrow blinks once in a while but noting on the download. None of the apps are connected to the network. Browser will show loading for a while and then displays no network connection message. I tried google play, youtube, third parts apps etc. to ensure its not just the browser. When I turn off the WiFi, the phone seams to download a bunch of messages and updates that was not being pulled for a while. My GSIII connects fine with the network and it works fine even after being idle for hours. I have no idea what is going on and would really appreciate any help. I am close to calling Samsung and T-mobile, but thought I will try here first as we all know how easy it is to deal with those guys.
Things I have tried so far: I have tried all of the following based on suggestions I read from other forums I found through google search.
1. Factory Reset the system: FAIL. After the reset was complete, I waited for everything to finish loading and then I connected to WiFi by inputting all the necessary details. Same results, will work for few seconds and stops.
2. Restart the Modem and Router: FAIL. I do not think it is modem or router related issue as my S III seams to connect and work fine.
3. Turn off the security for wireless network: FAIL. Same result as above.
4. Try different encryption: FAIL. Same result as above.
5. Forget the Network and redo: FAIL. Same result as above.
6. Change the IP address to Static in advanced settings for the network: Worked for a while and then this stopped too.
7. Change WiFi sleep policy: FAIL. Changed it to " When device sleeps", "Never" and "Always", does not make any difference.
8. Third party apps suggested by everyone: FAIL.
This is where I am at right now. I have tried to include all the information possible. Please ask me if any other information is needed.
Last resort ... try a warranty replacement.
Is the phone experiencing the same issues with other wireless networks (coffee shops, McD's)?
[Fixed]
The issue was not with the phone, but with the router/modem. This was the century link modem with wifi and router from walmart that was bought for $99. Its an actiontech router with built in modem for century link. This does not work and dont bother purchasing it. I ended up buying the NETGEAR DGND3300 RangeMax Dual Band Wireless-N Router with Built-in DSL Modem from Amazon (http://www.amazon.com/gp/product/B001UHMB5O/ref=oh_details_o01_s00_i00) for a 30 dollars more, but it works. Only extra step was that i had to call century link for my username and password that needs to be entered during the setup procedure. The actiontech from walmart did this automatically (mainly because this was a century link branded product).
I got a n900t a few day ago, but the wifi has problem , disconnect ...ect
so can it be fix with n9005 rom ?
Or i have to wait for the 4.4 kitkat from t-mobile ?
Thank you
Is this happening on every network or one specific network?

I was having issues with my WIFI also. It wouldn't connect on 2.4 GHz but would on 5 GHz. The performance wasn't great and I would get the connection isn't stable message a lot. I tried a bunch of things on my router and finally just did a factory reset on the router. I can now connect of both 2.4 GHz and 5 GHz. My connection speed has also improved dramatically. I didn't think it was a router issue since the Note 3 WIFI issues are pretty well known to be a problem. In my case, doing a factory reset on the router helped my problem a lot. For reference it is an ASUS RT-AC66R
I used the app WIFI Analyzer from the play store to monitor the signal strengths. Since doing the factory reset on the router, I only see the connection is unstable message very rarely.

You can turn off the option in the wifi settings that lets the phone auto disconnect from wifi if it thinks the wifi signal is weak or unstable. I sit 10 feet from my wifi router and it used to go back to the cell signal randomly. I disabled the auto switch option and no issue since. My wifi at home is very strong so I think its a bugged setting or something.
"Your network connection is unstable, so we in our smart thoughts have decided to disable it. Kiss my Gritts ". Ho Hummmmm
click dont show this option again
Wifi
If you are sure your WiFi is good, then go to WiFi settings,
1) Switch OFF Auto network switch
2) Keep Wi-Fi on during sleep: Always

Man, wish I had known about this... My Nexus 5 and 7 (and office iPhone 5S) all have excellent Wifi connection at my home.
I bought Note 3 to use the Wi-Fi calling feature and this caused me to missed multiple phone calls. Apparently, when the Note 3 is on Wi-Fi calling, it sorts of "disable" or reduce the cellular radio signal - zero bar shown on my Note 3 - all calls and SMS go through Wi-Fi. When the Wi-fi drop, it takes sometimes for the Note to establish cellular connection and that's when I missed the call.
Not to mention I am browsing happily or streaming Netflix and BAM.. wi-fi dropped and everything stopped.
If the Kit Kat upgrade fixes this issue AND not bring anymore problem (as evident from numerous threads), I would have upgraded to Kit Kat already.
Dammit, over the course of browsing for an hour, the wi-fi disconnect over 5 times.
What the hell!?
Has anyone experienced issues with Wireless?
I will be connected to a wireless network, can disconnect and reconnect just fine, everything seems to be working, but if I open an app that is trying to load data, it does nothing, as thought I have no connection. I have tried turning it off and on, forgetting the network(s) and reconnecting and the only thing that ever fixes the issue is a restart of the phone. Once I restart it will work just fine until the next "blip" in the radio.
Thanks in advance,
Zach
Yep, I have this issue but only when connected to my WiFi extender. Connecting to the main router works fine.
Just to add info, I connect to a Samsung Verizon Extender every day since owning the Note 4 and have no issues.
I also have never had any issues like the OP mentioned. I would start looking at apps you have installed.
Remove and test and so on. I did a quick search and did not find this to be any known issue.

I found this, maybe it will work, sorry you are having troubles.
Problem: Wi-Fi connection
Every time a new smartphone is released there are a lot of reports about problems with connecting to Wi-Fi networks or maintaining good Wi-Fi speeds. Here’s what to try if it happens to you:
Potential solutions:
Try turning your Note 4 and your router off for a couple of minutes. Now turn them on again and retry the connection.
Take a look in Settings > Power saving and make sure that low battery life isn’t restricting your Wi-Fi.
Try forgetting the connection, choose your router in Settings > Wi-Fi and Forget. Enter the details again.
Try the free Wi-Fi Analyzer app and see if the channel you’re using is crowded. Change to another channel if it is.
Take a look at the settings on your router. Make sure that MAC filtering isn’t on, or add your Note 4’s MAC address, which you’ll find in Wi-Fi > Settings > Advanced.
Make sure that your router firmware is fully up to date.

Thanks. Funny you should post this, I read it right after I posted here and was planning to check out the MAC filtering when I get home. Weird thing is this: My phone connects to the main router fine, with zero issues of any kind. We have a WiFi-extender by NetGear. My phone will connect to it, but will not exchange any data. My computers, HTC One, and my wife's old S5 all connected to the extender fine. Now, neither of our N4's will properly connect to it. It certainly doesn't seem like an issue with the extender, but that's not to say it isn't possible, and I sure hope that it is and not an inherent problem with the phone. Will try some troubleshooting tonight and report back.
I've run into an issue with the wifi since getting my Note 4 last Friday. The problem I am having is it will connect to my wifi network without any issues, but after a while (it could be 2~8 hours) my note4 will lose it's connection to the wifi router and not be able re-connect until I reboot the phone. I have a dual band ASUS router with the latest firmware, when the note4 craps on itself with the wifi, the wirelessG connection will keep asking for the password and come up with "authentication error" and the wirelessN connection will come up with "unable to obtain ip address"
When the note 4 has this issue, my router log shows "Dec 9 16:54:28 kernel: eth1: received packet with own address as source address", checking further into the logs on the router, this didn't start popping up until I got the note 4. I am hoping it is a software issue, Verizon did however confirm that there is an update coming out the the next few days to address a wifi performance issue...
I have other wireless devices that use both wireless G & N and don't have any issues, i've rebooted the router a few times even though that is not the problem. I even hooked up a different router to see if that would help, but the same problem is still there.
After playing around with different settings, I have yet to find a solution to this problem. Verizon support has me running the phone in safe mode to see if it's an app causing the problem.....
Are you by any chance using 5 GHz on your router? I am having issues with 5 GHz connections and no issues with 2.5.

No luck trying this.
Tried turning IPV6 on - in router settings. No difference. Turned it back off.
System web Viewer had an update. Updated. No difference. Disabled it. No difference.
Those two apps still wildly underperforming on wifi.

Hope you sort it out sir, I normally don't get unlocked on ATT due to losing WiFi calling but I get a better signal now and you can just call to get visual voicemail fixed if yours doesn't work right away so I'm loving it....
I'm sure you'll love it too once you get it sorted...
Bringing back zombie thread.
Was a fix found?
My 20+ is having problems with wifi slowing to a crawl after just a few minutes.
Just bought a new router TP-Link AX11000 and it started so I thought it was the router but everything else on wifi in the house gets expected speeds my two 20+'s not so. I think it has to do with WIFI 6. If I stay within 10ft of the router everything is fine after that... I go in my bedroom 30ft away and have -63dbm signal strength and I can run a speed test and get 500mbps down try again and it will start at 500 and slow to around 45 try a 3rd time and and I barely get 4mbps 4th time and it's 0 with signal strength still at -63 on all of the test in the bedroom my upload will be 45mbps.
after a lot of testing with battery settings and things on the phone found out that my slow wifi was due to 2 settings on the router.
first in your router disable WMM, this made my s20+ use like 30mbps max in my case. now list my wifi 5ghz as +800mbps
seconds, disable ipv6 on the router. this made my phone ultra slow to everything. like play store hang on app updates, google drive take forever to load every single photo, like is taking forever to get the first reply from the server.
with that changed now the phone works at full speed on wifi. play store updates are shocking fast.
so lame that a flagship that cost nearly 1 thousand dollars have to disable things externally to work properly. no other phone or device works bad with the previous config of WMM or IPv6. I have a Linksys WRT1900ACS.
Hope they fix it with a software upgrade.
