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 And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me.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
I just got my SGS2 today and tested it with a friend. He had wireless and everything was working over there. When I came home, I couldn't connect to my wifi. I always get 'obtaining ip address'...
I've been searching whole night and I haven't been able to solve the problem.
I can connect to my wifi when I enable the dhcp server, but then I can't access the internet anymore.
Network setup:
Modem -> Switch -> Wireless Switch
I get my ip address directly from my provider (Telenet - Belgium). I've no router at home and it works with every device, except for the GS2S.
Someone experience with this? Is there another way then to buy a new router?
Thanks in advance

Hey guys,
Just updated my SGS2 to ICS (see screen shot for version details). While im still getting used to a few of the changes, i have noticed a reasonably annoying bug which is causing my wifi at home to drop out. The phone will not hold a stable connection.
I updated my phone while at work, then when i got home it did connect to my network with no hassle, but after a little while (maybe 30 mins) i noticed that i kept getting notifications that i have connected to my home network. so it seems that a connection to the home wifi network is made, then lost, then found and re-established, then lost again. I have observed the 're-connection' can be as frequent as every 30 seconds, but sometimes it will hold the signal for up to 10 minutes.
the wifi signal strength is strong, as i do sit quite close to the router.
does anyone have any similar issues to me? Anyone know of a solution?
Thanks heaps for any help.
ps: you will notice from the screen shot that i have installed Wifi Fixer from the market, this did not help stabilize my connection.
Thanks again.
hmmm
Have you tried manually setting your network values?
I was having this issue as well using my phone in DHCP mode, but when I assigned a static IP, it worked great.
On a side note, what router are you using?
Gday mate,
thanks a lot for the reply. I changed the IP setting to static, though i didnt have to assign one. does that sound right?
Anyway, it seems to have improved the stability - i havent noticed any more drop-outs. Ill keep and eye on it and let you know.
I'm pretty sure the router is a Netgear DGN-2000, but ill confirm that. We also use a WIFI booster.
Thanks again for your help mate.
Same problem I think
My phone got ICS recently. It worked no problem in my sister's flat but now in my aunt's place. Doesn't work, it will connect with the router. It will work for about a minute and that's it. No more internet but still connected. They use a booster as well and this problem of wifi connection issues is common it seems.
They only way I've found ti help the problem, forget network, clear internet cache in applications and restart the router
Hey guys,
Wasnt sure where to post this. Have a question regarding wifi conection settings. I was on omega v34 and everything was fine. My phone connected to all wifi networks I wanted it to. I updated to v35 of the rom and now I have a strange problem.
My phone still connects to my house wifi and work wifi, but refuses to connect to my parents wireless. Ive reset their router, changed the password and removed the settings for the network on my phone. When I refresh and attempt to connect to it all I get is "authenticating" and then it will give up. It is a BT home hub and the strange thing is that my phone will connect to the 'free wifi' BTwifi-with-FON and the BTwifi, but not the proper network zone BTHub3-T2G6. Its incredibly annoying.
Are there any hidden settings in my phone that may have the wrong settings for the network in it?
Any help would be appreciated
EDIT: Just turned the security off on the network and the phone connects fine. I dont understand why the security key would cause problems as it connected before the update and the settings havent changed.

Hi,
Has anyone had similar experience and (better yet) a solution to my issue with wifi connections since upgrading to 5.0?
After the update my Ultra Z GPE losses connection to my home wifi, and other wifi (public wifi,, friend's wifi). Once this happens the wifi app in settings does not see/list the wifi connection. I've tried turning wifi off/on, and refresh but my home wifi (and the public and friend's wifi) do not appear as available. The only solution I've found is to power off and back on again. But doing this several times a day is a pain.
TIA

Well my situation has changed, and perhaps a little less of a pain. Even though in Settings it shows my wifi is connected I am still frequently losing the connection. My apps (i.e., Google browser, Google Now, other apps, etc) do not load/refresh and indicate "No network connection. But now I can resolve the problem by toggling wifi off and on. Better than powering off and on but still a pain.

If your device is rooted try Wifi Connection Fixer ROOT by Zextr. The link is

Thank you for your response. But no my device is not rooted. However, I believe I found the cause of my wifi issue. Separate from my wifi issue I was having some issues with Google Now. So, I uninstalled the Google Now launcher. Guess what? My wifi issue is gone. I have not lost wifi connection since I uninstalled the Google Now launcher.
