Hi, is anyone has the same problem? When I'm connected at home to my Tenda router (WIFI b/g/n) after cca 30 min. my phone WIFI stops sending and recieving data, Skype is offline, etc... but WIFI in phone is stil switched on. After I switch WIFI off and back on (on my Samsung, not on my router), everything works good for a while and after cca 30 min. is situation the same. Is there in Samsung any WIFI sleep mode or something like that? Or some settings, which is not visible? Any other suggestions? Sorry for my poor English. Thanx in advance.
I'm having the same problem. But I did a factory reset and it works fine afterward.
And just few hours ago, I encountered this problem again. What did to get this error was, I pressed "on samsungapps" and it failed to update and thus results wifi connection stopping. What about you? Also my Kies air is not working.
are you guys sure you have wifi sleep policy set correctly? just to be sure, settings, wireless, wifi, menu button, advanced, wifi sleep policy to NEVER.
Yes. And also even if i manually disconnect and reconnect the wifi back. The data still doesn't come in. It is stated there as connected but no data at all.
Somehow Wifi keeps searching every few seconds, even thought it's connected.
This is bound to cost in battery life too.
I have reseted router to default settings, disabled n mode, disabled security (only mac filtering is on), disabled all unnecessary features and PROBLEM IS SOLVED !!! Thanx God Tomorrow I will experiment with router settings to know, what was causing this error ;-)
Well at least u're connected, I'm facing the same problem as the thread starter. No data flow at all. Browser showing me offline msg. I had the same problem on the 1st day with the phone after I woke up. previously playing with most of the default aps. So i'm not sure what went wrong, did a factory reset and it works fine.
Until, few hours ago, I tried my kies air which didn't work. Browser couldnt load the address given. And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me. At that point the wifi is still working, i leave my phone for about 30 mins, and when i came back. The same problem which happened on the 1st day came back. I was hoping to find an answer here so I didnt do the factory reset it. On another note, the phone wifi works after restart, but wouldn't last.
Edit: The wifi works after i resetted my modem to default. oh well. at least that solved it.

Hi,
Did you find out what setting was causing the connection issue? I also have this problem with my Tenda router. I thought it might be the wireless N, but disabling that doesn't fix it. I have a wireless distribution system set up with other tenda routers so didn't want to disable all the settings to troubleshoot if i can help it!
Thanks

I have the same problem, my router is N and the conection between SGS2 and my router is bad. Any idea?
Same problem here, I'm running WZR-AGL300NH in access point connected to my Ubuntu Server. Everything else works in the house just fine but SG2 stops transmitting data after a while.
I recently upgraded to KF1 firmware (and unknowingly wiped out whole phone, being on the bleeding edge and that didn't seem to help.
I would very much appreciate all tips because this problem is very annoying!
Additional Info:
- Buffalo is running latest firmware
- Authentication WPA2-PSK
- Encryption AES

Same symptoms here. Cisco DDR2200. WPA2 PSK. Haven't tried fiddling with the router yet.
This seems to be a common problem. Anyone knows of a definitive fix?
Bump...I have the same problem and the issue persists even after i reset the phone

Glad I found this, thought it was the ROM I had flashed to the phone (which is VillainROM)
I keep losing connection from my phone via wifi like everyone else in this thread
edit: I've just assigned my phone an IP address via my routers settings and I can connect to the net again
Also when it wasn't working, I couldn't ping the phone. When I assigned the IP just now I still couldn't ping it.
When I did a tracert to it, I could get to it when the IP was assigned and when it wasn't.
I have no removed the assigned IP for the phone from the router. Wifi connection is still working after disconnecting/reconnecting wifi on the phone.
I can also now ping the phone, where as before it was getting timeouts.
Also when it wasn't working the first time when I did a tracert it was showing up as HPsomething (didn't make note of the numbers)
this time when it is working it's just showing up as the IP address when doing a tracert.
Another update:
Just checked my printer, it has an IP address manually set on it, which at one stage when the phone wasn't working for internet it had the same IP as the printer, hence when tracert'ing it I was going to the printer instead of the phone and getting the HP etc back.
When it wasn't working at that time and looking at my routers DHCP list, it had the MAC Address of the phone against the IP that the printer has....
So I've got some issues with how my own network is setup ^_^ which looks like is causing me grief.
So the issue is with DHCP? Setting a static IP fixes it? I'll have to try, but I doubt this is a problem with the network, as all my other devices use DHCP without this problem.
I have the exact same problem!!
It's really annoying.
i was having problems with wifi too.. it keeps scanning and checking, etc, signal dropping for no reason..
fixed mine..well for me it worked
backup ur phone ( i dont take responsibility if ur phone catches fire or dies or chases u around )
u need to be rooted
download FXR WiFi fix and rescue from market
and just run the app.
now my wifi signal stays constant speed and i get good speeds
alternatively try
WiFi Fixer
both of them will cause high battery usage..i think since it keeps the signal at maximum.. so only enable wireless when i need it or use juice defender or green power.
greenpower seems great. using this at the moment
I've tried searching and haven't found anyone with the same issue as I.
Jellybean broke my wifi, I had no connection issues before whatsoever.
Now, it still shows it's connected to the network with full strength but when I go to use the internet or any apps, it says there is no network connection, webpage unavailable, no autosync, etc. Things are fine when I go back to 3G and nothing has changed on my phone but the JB update. I've turned Sprint Optimizer off and on, deleted and manually readded all the wifi networks, and am not sure what else to do besides hard reset. Any ideas? Also, I am not rooted.

have you done a complete network reboot (cable modem and wifi router) when having the crappy sprint connection optimizer off?
if this helps you feel free to hit the thanks button
Thanks for the help! I found the answer in another thread... Seems JB automatically turns on "DLNA auto-ip" for some people. The fix that worked for me was Settings>Wifi>Menu>Advanced and uncheck "DLNA auto-ip" at the bottom.
Rooted stock ROM Verizon I605 running 4.1.2.
I was in Korea for the past 6 months and just got back the other day. Before I left, I never had any problems, but since returning, my wifi and data are on at the same time, and it's causing me problems. Here's what's going on:
If I just have mobile data on, everything works as it should. If I turn on Wifi, it will connect, but the data connection will also remain, and my internet speeds will become spotty. If I turn on mobile data and just try to use wifi, the Wifi icon appears (with the orange/green arrows indicating activity), but apps don't connect. Facebook automatically tells me "No Internet connection," Opera won't load pages, Google Talk can't sign in, etc. If I turn mobile data back on, things work again, albeit slowly.
The strange thing is if I turn on Airplane Mode and then turn it off, leaving data off, my wifi will work 100% normally. If I try to turn on mobile data again, I get the same issue.
While I was away, I replaced the SIM card so I could use my phone over there. I messed with some APN stuff thinking I would be able to get data on my phone in Korea, but that didn't work out so I returned my APN settings to default. I have a feeling that's the source of my problems, but I have no idea how to fix it. I tried restoring my APN settings to default through the settings, but that didn't fix it either.
Any help at all would be appreciated!
If it helps I have been seeing the same thing. I'm on CleanRom 3.5 (Verizon Rom base) and PB&J kernel. It seems to be hunting between them even when in strong wifi signal.
Interestingly enough it's not doing it right now.
I'll keep a closer eye on it now.

In my case, it's a constant problem (unless I manually go into airplane mode, like explained). It doesn't work sometimes and not work other times.
I'm trying to use wifi at home, so signal strength isn't an issue either.
Ever since I received my OPX I had little problems with my data, independently of using Wi-Fi or mobile internet (2g/3g).
It started with the fact that in the installation of the phone it couldn't connect to verify it's connection, although wifi was connected correctly.
I started it without the connection it wanted and factory resetted it and then I got the same problem, but after a few minutes it worked correctly and I could install my phone without any problems.
Now when I work with my phone (Whatsapp, 9gag, webrowsing, video streaming) it sometimes stops with loading, like it has lost its connection, but both Wi-Fi and mobile internet are connected.
This is very frustrating when watching video, since it just won't buffer anymore and I have to wait for like 1 minute before it continues and reloading the page helps most of the times, because I then force to get data.
Sometimes when WhatsApp isn't loading/ keeping it's connection I just start a SpeedTest to ensure it has an open connection. This works most of the times.
Also WhatsApp Web keeps losing its connection while the screen is on.
I hope you guys have some ideas on this subject.
I have a similar issue. In my case the device seems to have problems with certain WiFi-Networks (at university to be precise). The connection with the WiFi is still there, but there's no actual connection to the internet sometimes. That's why your mobile data doesn't activate - there are no connection issues on mobile data for me.
The cause for this is probably the lack of a 5GHz WiFi antenna. I don't know why, but my OPX cannot handle the 2.4GHz WiFi at university (at home it works fine!).
So to test this out, you should try different WiFi-Networks. If the network is 2.4GHz only, it should be working.
The WiFi thing while setting up the phone is a known OxygenOS bug and can be worked around.
I have tried different Wi-Fi connections but it sill once in a while tells me that specific app can't work on Wi-Fi, only with mobile data. The issue with that is that I don't have good signal reception at home. Would appreciate any suggestions to solve the issue. I have tried several solutions found online such as: uninstalling and installing back again with a backup, deleting cache and data, resetting Network settings. I have never had an issue like this before with anyother phone.
You can keep the Wi-fi connection at the center of the house which will cover eventually every place, or keep it closer to your room so it won't get disconnected! As for the apps, you can go to the app settings and change the network usage from mobile data to wi-fi. Which apps are not connecting to Wi-fi?

It only happens with the WhatsApp app. I think I found a workaround. This problem may happen if you have multiple access points in your house. Even though is not a proper solution (the issue never happened with my old phone), you just have to turn off and on Wi-Fi and dismiss the notification. WhatsApp will probably work fine after that.
