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 And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me.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
Hello,
I got problems with my 3G connectivity. I've read this topic also:
http://forum.xda-developers.com/showthread.php?t=1239777
And manually selected my provider (Telfort).
But, my WiFi connection is also bad too. Sometimes it stops giving internet too. So I have to reconnect to the WiFi access point.
Beside that, When is coming 2.3.4 update to The Netherlands ?
Thanks.
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
Hi all been having problems with WiFi on AOKP/cm10.1 ROMs for the last few weeks when I try to connect I get authenticating IP loop then avoided poor connection even though my WiFi connection shows full bars the solution was to go into the router settings and change the connection to n only instead of auto b/g/n also weird as it sounds my wife has a s3 running the same ROMs and she never had the problem anyway hope this help someone
Hello team,
My Samsung Galaxy S3 GT-I9300 (international version) started to have wifi problems after stock update to 4.1.2. After that, I´ve tried many software and hardware fixes, including changing the wifi antenna cable. The result was the same, so I decided to try custom ROMs and came straight to CM11.
The wifi signal is very weak, and I can only connect from a few meters from the router
Installed CM11, full wipe cache/data/dalvik and still the same problem, weak wifi, connection only from if close to the wireless router.
Reading all the forums on XDA and CyanogenMod, I found the wifi-fix patch, which writes "murata" on the /data/.cid.info. This fix brought me powerful wireless signal, and now I get full signal bar to my router and even see many neighbor APs... but I am not able to connect. When I try to connect, type de password and than it just goes back to "Saved, protected by WPA/WPA2". I´ve also disabled authentication on the wireless router, and the result is the same. It won't connect not even to open networks, although I see strong signal.
Deleted the wifi_fix patch (delete ¨91fixwifi¨ on init.d, delete ¨.cid.info¨ under /data and rebooting), and went back to old status: very weak wifi signal, but able to connect (associate) if I´m very close to the router.
Turned wifi on and off, airplane on and off, captured log on "Murata" and "Samsung" modes...
Strange is that my wlan mac address is 88:32:9b:xx:xx:xx, which seems to be Samsung, but the Murata brings me powerful signal (although I cannot connect).
Well, I´ve tried many solutions so far, but that´s how far I could go...
Can anyone provide me some clue to solve it? I would be very thankful to have wifi back to my phone.
Log files are in attachment
Murata log (strong wifi, not able to connect)
Samsung log (weak wifi, able to connect when very close to wireless router)
Thank you all!
I too have only a range of 3 metres, I have 7 routers in the house because of this, yet I have less than 15% coverage of the house with this device. To put that in perspective, an HTC One X and Atrix 2 has 90% coverage with 2 routers. I'm 1 metre from the router in my room and I've got 1 bar, sometimes 2 briefly.
[Edit]
Woah, I tried the fix from:
http://forum.xda-developers.com/galaxy-s3/help/cm9-i9300-advice-t1898004/post41394293
Seeing as it can easily be reverted, it displays very high signal. What I'd expect. But it doesn't let me connect either. I also tried CM10.1 like the people who it worked for, it didn't work.
