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, 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 went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

I have same problem. I have SE xperia mini with CM9. WiFi worked fine until yesterday. Now phone can't connect to AP (full signal - try connect -> signal drops down), but sharing 3G internet over WiFi works fine. I cleared dalvik cache, but that didn't help.
is anyone having a problem with the wifi after updating to jellybean for s3?
inital connection to WIFI works but after a certain period of time, the wifi stopped working and i need to restart the wifi again for internet to load. IT happens all the time now after leaving my phone with WIFI on.
Constant restarting WIFI to get connection does not happen in ICS..

No such problem for me with JB LJ5 stock or custom!!!
Might be your modem-router....
This happens to me too. It's fine for me at work, but when I'm at home the wifi fails to connect after some time. Are you using dd-wrt at home? I am and I'm wondering if that's the issue.

I find that having my wifi set to always on in advanced I get better wifi and slow drain, having it on wifi off while asleep makes your wifi keep disconnecting and reconnecting. Best way is to switch wifi off when you don't need it.
Also some battery saving apps I've found to stop wifi and need to keep reconnecting, this has to be changed in the settings
wi fi dropped

Hi, Mine is Galaxy Note 2 i317 with Jelly Bean 4.1.1. I did have similar issue. I took two smart phones to Target, one is ICS 4.0.3 and the Note 2 is 4.1.1.
The 4.0.3 never has any issues with wi fi connection. But the Note 2 keeps on dropping the connection. I ran an application wifi analyzer to check the available networks. It turns out that Target has so many routers that are using the same ssid, i.e. "Target Guest Wi-Fi". There are channel 1, 6, 11, etc, as well as many 5Gs. I did an alias for every available connection. Then I pick one of the stronger signal strength 5G and connected to it.
After that no connection was dropped.
The point is that you should try to connect to the strongest signal SSID so that the Note 2 won't keep on dropping the weak connection.
I have no idea why the ICS 4.0.3 can handle better than the 4.1.1 Jelly Bean as far as wifi is concerned.

Same problem!

I'm experiencing the same problem since updating to Jelly Bean 4.1.1 on my HTC ONE X. So it seems to be an Android issue, not specific to Samsung or HTC.
I connect to my home network over WIFI, everything works fine until after a little while my apps seem unable to connect to any data/internet. They just time out or come up with error messages about connection problems.
Sure enough, if I disconnect and reconnect to WIFI, everything starts working again... for a little while.
It's like the WIFI goes to sleep, but forgets to wake-up again.
And there is no indication on the phone, ie. it still shows as connected.

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
So far I'm loving this tablet (even without root) but have noticed that I lose internet access if I'm browsing for a long time. I still have full Wi-Fi signal (I'm only a couple of feet from my router) but no internet access until I disable and re-enable Wi-Fi. This has happened several times since getting the tablet last Friday. I have 3 other Android devices including an Xperia Z1 and none of those have a problem. It has happened on two different Wi-Fi networks so it is definitely not a router issue. I have tried disabling and enabling the options under Advanced Wi-Fi such as 'Scanning always available' and 'Wi-Fi optimisation' but none help.
There is a Wi-Fi Check app preloaded on the Z3TC and it shows it is failing on test 4 - Gateway/DNS. All of my other devices remain connected.
Anyone else noticed a similar problem? I know it is early days but would like to know if I should return it before I get too attached to it!

Just the 16GB Wi-Fi only version. I did some tests on my work Wi-Fi (streaming music and browsing) and the connection was stable. I'll try static IP and a few other things and test again at home.
Cheers
Yep, I have the same problem.
Wifi connection is not stable. Sometimes I have to wait for few seconds for it to reconnect.
Mine is 16 gb Wifi version only.
Is this a software issue.? Wondering if I should return it.
Anyone found a solution?

Actually, I haven't the problem again since the first week. I'm thinking it may have been a router issue after all (I'm using a Virgin Media SuperHub 2). I've not had any disconnections issues since.
Have you tried the Wi-Fi Test app?
