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 And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me.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
Got an s3 today from radioshack. I had an S2 before. I went home and tried to connect to wifi like I normally do. I use WPA2 Personal TKIP+AES encryption with MAC filtering enabled so only devices I know about can connect on my WiFi (friends were jerks and I needed a way to control who gets on.) Anyway, I added the Mac address to the list of trusted devices and tried to connect after putting in the WiFi password. I was unable to connect and the error message it gives is "authentication error occurred" "incorrect password". A bit of trouble shooting later, because i knew the password was right. I decided to disable the MAC filtering for a moment to see if I could connect. I was able to connect, but as soon as i enabled the MAC filtering it disconnected with the same error.
My Question is, is there a way to fix this problem? Without rooting and without disabling MAC filter permanently
Things I have tried:
changing the frequency of the router tried channel 1-11 (phone only works on channel 6 with filter disabled)
changing the authentication type
removing re adding the mac address
rebooting the router
rebooting the phone
standing in-front of the router with the phone pass-phrase input
dialing *#0011# and turning off power saving on the WiFi
I assume you've double checked the mac address is correct? Ensured lower case for a-f chars? Oddly it does seem as if its an incorrect mac address.
Does your router show macs of connected devices if you turn filtering off? If so, copy / paste from there?

just wanted to update and let you guys know whats going on. I found out what the problem was, and I am currently taking steps to fix it. So the mac filtering is the problem for sure. I did not input anything wrong. I found out that because the S2 and the S3 are similar the mac address of both phones cant be added at the same time or neither device can connect to the network. I decided to root the S2 and change the Mac address so that both devices should be able to connect.
Better than rooting the S3 since i dont have insurance on it.
anyway hope this update helps someone else who has the same problem.
my phone was working well for few days ago then stopped connecting to my home network.
I've tried to reset the router and changed wpa to wpa2 no effect, restarted the phone few times still no change. :crying:
it keeps give me incorrect password ( my password is only in numbers).
after that i reset the phone and made my network open and still nothing cannot connect to wifi network
any solution suggested.
Hello,
Every known wifi network I walk into, I get an wifi connection failure and my phone does not get connected. After going to the wifi network settings and manually choose connect, there is no problem...
Also overnight, my connection get lost and when I wake up I have the same error. I have to do the same thing (manually connect to my known wifi network(s).) before I can use it...
Deleting the network and adding it again will not solve the issue. I have attached the logcat. I also have enabled extended wifi logging for the logcat.
At 16.21 I enabled wifi and it does not connect
At 16.50 I manually connect to the network
Does anybody know what's going on?
Thnx!
Another logcat during night. Somewhere I lose my wifi and my device won't reconnect.... I gave to manually choose reconnect on the known wifi.
I already deleted the data in data/misc/dhcp and data/misc/wifi and removed all the known networks and start adding them.
Already did a full wipe (factory) reset with no results..
The wifi randomly disconnects and with the error: Authentication Problem. The phone wont reconnect to another wifi hotspot until I manually make it do it. This happenns on the 5GHz band (I haven't tested it on 2.4). This problem doesn't happen with any other device connected to the same wifi router. Does anyone know what could cause this problem?
I had a similar problem where my G5 took ages to connect to WiFi and then it would randomly disconnect.
Try deleting every saved WiFi network you have, except for the ones you use. Just long press each one and hit "forget".
See if that fixes your problem.
I have only 2 saved networks (the 2 bands: 2.4 and 5). The wifi worked without any issue for the last two weeks until yesterday when the phone disconnected with the Authentication Problem error. I have to mention that the phone connects immediately to the wifi if I manually select the network and when I turn on the wifi.
I would then suggest the problem is with the network.
Either reset your network (unplug router, wait, replug) or try with a different WiFi.
I had an outage a week ago and that problem persisted until my provider fixed their problem. These "authentication" issues can be from anything network related.
I will try with another router. The annoying part is that I cannot reproduce the error manually, it's way too random.
