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 And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me.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
Sent from my GT-I9100 using XDA App
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
Hi guys, I got a problem with my T10. Whenever I'm doing something that uses WiFi, I keep getting D/C'd. Its not my router, because I have other tabs in the house which are fine. WiFi sleep policy is set to Always Keep On, and I've tried apps like WiFi Keeper and WiFi Static which don't work. PLEASE HELP!
Please, anyone?
Noone?
I have the same problem with my alcatel one touch t10. If it goes to sleep, it disconnects from my WIFI connection. Settings are already set to keep wifi on at all times. Any assistance will be very much appreciated.
Hey guys,
OK Ive got a strange problem with one of my Galaxy S3's!
It will not connect to some WIFI connections! It will say 'Obtaining IP address' then 'Failed to obtain IP address' and then loops itself doing the same thing over and over...?
I have two S3's and my other rooted device is fine. The one that has the problem is running a standard O2 4.3 rom (Un-rooted)
My rooted phone is also running 4.3.
Anyone experienced a similar problem? I have had this problem with 4 or 5 WIFI connections now, including my home one which is rather annoying! I have tried the obvious and rebooted my router, which hasn't helped!
Any advice welcomed!

I've had issues with the quality of my internet connection being checked, and then the connection being killed due to "slow internet connection", even on strong Wifi networks. Solution turned out to be to uncheck the automatic network switch in the advanced Wifi settings.

How so, when I have an identical phone sat right next to it with the same version of Android and that phone connects perfectly?
The only difference is one phone is rooted, the other is not (Both running 4.3, just different kernal number and build number)
Well wifi is a function of the kernel .
Hi everyone
Does anyone came across wifi problem like my Alcatel, I'm on android 4.4.2. I get wifi signal when I close to the router 1 meter, I can connected to wifi no problem. But if I move farther away I lost wifi connection, I don't know if the software issues or it there fix? If anyone have the lollipop for this Alcatel pop icon,I would like to flash it to see the wifi can be fix.
So yesterday I tried connecting to eduroam (a 802.1x EAP-TTLS network) with a Gretel A7 (cheapo chinese phone, MTK 6571 chipset and MTK 6580 CPU).
Also this is Android 6.0
Since the network wasn't showing up (which was weird, on my laptop was working fine) I tried to add it up manually.
After setting up everything, and hitting connect, my wifi would find ANY networks anymore.
I tried deleting the network from the wpa_supplicant.conf, but it wasn't enough. So I had to do a factory reset (wifi got to work BUT: was extremely slow, disconnected many times from the network, gave limited connectivity many times as well, and wouldn't find as many networks as before).
When I got home I flashed the stock rom, but my phone's wifi was still having the same issue.
I believe this phone is not ready to connect to a EAP connection, maybe? What can i do to fix this phone up?
I've been messing with the /data/misc/wifi/ folder trying to figure something out but still made no progress.
PS: PLEASE, ANY HELP IS MUCH APPRECIATED.
PPS: Also, if anyone could lead me to a more proper forum, I'd gladly close this topic
