Anyone else seen this issue.. every few minutes wifi stops working.. if i disable and reenable wifi it works fine.. signal strength is fine.. doesnt happen on older sgs phone.. and didnt happen on my last firmware g1... anyone else seen this.. i am trying to flash an older modem now..
more info .. it was actually some kind of problem with dhcp lease.. every 10 minutes when lease was lost it would loose wifi.. Strange no other devices in the house using dhcp had an issue include the 2 sgs's we have..
anyway rebooting router has fixed it for now..
thanks
Have you checked WiFi sleep policy under Advanced settings?
wifi sleep policy doesnt affect this.. either way when unsleeping it is supposd to resume wifi.. and does on other devices. an works either way now that i have rebooted router.

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
So I have my Fascinate running CM7 with the Glitch Kernel, no OC, just for the stock UV, the problem I have is that I can connect to WiFi, everything seems fine and then a few minutes later everything stops loading, as if there was no connection. turning off WiFi and turning it back on helps about 80% of the time but still an issue, the reason this is so big is that at my house we have no reception at all, Verizon sent us a Network Extender but it simply does not work on any phone and I know for a fact that my Network is fine. (We have twin N600s one routing one access point) Additionally the issue is at the local college as well. Any help? Is there an issue with CM7 or the Glitch kernel?
I am having the exact same problem. For example, market will stick at "Loading..." while on wifi but when I turn wifi off, my 3g connection will load market fine. It's so weird because I have full wifi signal and it is definitely not my router. It didn't start until I flashed the glitch kernel. Has to be something there. Maybe there is a workaround?
Im running glitch v13 and wifi works great. sometimes after a reboot ill have to toggle it off/on...

I had that Market problem and it disappeared when I got a new router. A full reset/wipe of router may have fixed it also. Happened on 2 CM7 phones (Droid2 and Fascinate), but not a stock 2.3 Droid2.
On my CM7 Fascinate, I usually also have to toggle wifi after reboot.
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 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.
Anyone else noticed Wifi problems with the new ROM?
It was OK for a while then noticed the next day or so it wasn't connected. I tried manually selecting the SSID but it would not connect. I tried forgetting the SSID and re-entering the password but it wouldn't connect. A reboot finally cured the problem and it was fine for another day. I haven't worked out the patern yet I'm guessing once I leave the WiFi signal area it never regains connection?

With the latest update my wifi won't even switch on.
People suggested that I should flash stock firmware, which I haven't tried yet.
I will let you know if it solved my problem once I do flash the stock firmware.
I have the wifi problem today when i update my mega, just do a factory reset and then update your mega again.
