Hello,
Not long ago i decided to wipe everything from my device and install new rom and kernel just to fresh it up a bit, i want to highlight this: Before i did it, everything was Alright, at least everything related to internet and WiFi.
Anyway, Since i did it I'm experiencing problems with my WiFi connection (at least when I'm connected to my home WiFi router)
Everything Seems to be OK, i have the WiFi icon on the status bar, with at least 1 or 2 lines of WiFi reception (Same like i had Before i changed ROM and everything was alright)
The problem is that some of the time the WiFi is alright, i Can surf the web and use internet apps like Facebook and YouTube, but Most of the time.... Well i just can't... I do have the WiFi icon but the internet doesn't respond...
Another thing, I'm using laptop and connected to the same WiFi network my phone is connected to and everything is just fine... so the problem is with my Galaxy S2 Device and not my WiFi network..
I found a way to solve it and about 60% of the times i disable and enable WiFi my internet works again for some minutes...
Does anyone got a clue what my problem could be?
Thanks!
Try a different modem ..
Try a different rom .
Put your old rom back on .
jje
i Have tried several other modems and nothing changes,
About the ROM i really want to stick with my new ROM and i haven't heard of anyone using it experiencing same problems...
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.
Im currently running latest paranoidandroid ROM and it seems that several times a day my signal and data goes color grey, while im in this status, i cannot receive any whatsapp or any connection whatsoever, i can receive calls tho.
Any idea how can i fix this ?
PD: same thing happened with latest rootbox ROM
I've noticed the same on multiple ROMs. It will be grey for a second or two then turn blue. I assumed it just meant it was in the process of connecting (e.g. wifi authorizing etc).
If for example I am connecting to a hotspot at Starbucks, I can connect to the wifi and the wifi bars will be grey. Then once I "login" to the Starbucks wifi where you agree to the terms and conditions, it gives you full internet access. That's when my bars turn blue.
It might be similar to the "limited connectivity" you get in Windows, connected to the network but with no internet access.
Though I might be completely wrong

Well yeah, actually, in my case, this does not only happen when connecting to wifi, it does happen at random times of the day. This is kind of annoying cause i lose data conectivity for a while and am unable to receive any kind of internet-related notification. :S
Anyone ?
My signal and Wi-Fi bars turn blue only when they're full. If i lose one bar they will turn grey. I lost Wi-Fi connectivity when I put to sleep my phone and fixed it by changing the keep connected while suspended in the advanced settings.
I've tried searching and haven't found anyone with the same issue as I.
Jellybean broke my wifi, I had no connection issues before whatsoever.
Now, it still shows it's connected to the network with full strength but when I go to use the internet or any apps, it says there is no network connection, webpage unavailable, no autosync, etc. Things are fine when I go back to 3G and nothing has changed on my phone but the JB update. I've turned Sprint Optimizer off and on, deleted and manually readded all the wifi networks, and am not sure what else to do besides hard reset. Any ideas? Also, I am not rooted.

have you done a complete network reboot (cable modem and wifi router) when having the crappy sprint connection optimizer off?
if this helps you feel free to hit the thanks button
Thanks for the help! I found the answer in another thread... Seems JB automatically turns on "DLNA auto-ip" for some people. The fix that worked for me was Settings>Wifi>Menu>Advanced and uncheck "DLNA auto-ip" at the bottom.
Hi, I have a Galaxy SII from AT&T and I have problems trying to connect the wifi at home, When I tried the mobile is connected just for a few seconds and then suddenly it is disconnected, but the wifi network still displayed. If I go to youtube, fb, twitter or any other application the icon shows the green arrow saying data is sending, but the orange arrow is not flashing. I tried to connect to other wifi (public places or friends) and it is working fine without disconnecting. One thing I notice is if I try to connect at home and start tune in, I will be connected always meanwhile tune in is running. My ISP is Century Link and my laptop and ipod don´t have problems, just the galaxy. I called the ISP and they said everything is fine with my signal and my modem. No I have the app wifi fixer running just to reconnect each time the mobile doesn't have wifi signal.
My galaxy is unrooted, running Android 4.0.4 Baseband I9100XXLQ6 Kernel 3.0.15-1114882 build number imm76d.xwlpy
I hope somebody can help me.
tried erasing your home wifi settings and re configure it?
might be a conflict.
Thank you, but i did it also i removed all the wifi network and still the same problem

This will be hard to debug without further information.
You should try to take a look at the log files of your phone and your AP. On your phone use CatLog to record what is going on when you try to establish a Wifi connection. On the AP side the manual will tell you if and how you can access log file information of the AP.
i'm still smelling ip conflict....this might not be a phone problem but a router problem.
might wanna look into that.
FYI, though your question is general enough that an answer provided here may be relevant to you, this forum is for a device that is different from yours.
The AT&T Galaxy SII has its own forum: http://forum.xda-developers.com/forumdisplay.php?f=1301

My Galaxy is SII I9100 unlocked, that's why I posted here my question. I don't have problems whit the carrier, it is with my home wifi only. I removed all the other saved wifi connections, made a factory restore, but still having problems. My modem is brand new, I have 2 weeks with it. all other devices connect correctly and don't loose the connection, even my Ipod, also I set a static IP to the sgsII without results. I only have internet for at max 40 secs then the wifi icon is showing just the green arrow (sending data) but no orange arrow (receive data). My only "solution" at the moment is us wifi fixer, I installed the cat log as one of the user responses but I don't know which word I have to track there are many WIFI.
try setting your router to dynamic assignation. I'm pretty sure that is an IP conflict.
Problems started - with the phone only - around the time you got the router?

Hi my router is in DHCP mode, I only have 3 devices connected, my laptop, Ipod and galaxy sII, the problem is present only with the phone, I followed this video and changed the wireless channel and the internet holds for a while but after 5 mins I don't have any response from the router. just the green arrow. Modem model Actiontec C1000A attached are some images of my router configuration as well the log, it shows the elapsed time between connection and disconnection it is because wifi fixer checks the connection and
tries to repair it if it not possible then turns off and on the wifi
I have the very same Problem! Internet works for a few seconds or minutes. Suddenly all downloads etc. stop and only one arrow in the wifi symbol is flashing. Tried a lot of things now. Have no problem with other networks.
What i tried:
g -> n (but one of my devices don't supports n =( )
20 to 40 MHZ -> No connection @ all
Fixed or dynamic ip -> same result
All other devices work great with my thompson router. Disable and Enable of the WIFI give's me a few more minutes with connection. Programmed now in tasker that wifi is disabled with display of...
Greatz

You said it was "from AT&T", so I assumed you had an SGH-I777, which is the model AT&T sells. I stopped reading, so I missed where you said it was an i9100.
Anywho, try changing the channel on your wifi router.
Look at this guy & his S iii; doesn't ring a bell?

I have changed the channel and it improves, but still disconnecting after 5 minutes

So did you try all the other ones?
I tried with all the channels, still same problem, also with static IP and the problem still there, my only workaround is connect to wifi, start immediately tune in, and the mobile is able to receive emails, whatsapp, etc. but if I tried youtube, then tune in is disabled and the video starts the streaming but suddenly the mobile is not getting more data from the router, I'm able to watch just 1 video 2 min long

What should bother you is that you can connect to any wifi network, but your home's.
Burn that router down!
....or try another one.
yes, I will call to my ISP and ask for a new one. Sometimes I want just to watch some youtube videos without turn on the laptop or simply use my wifi to save some Mb from by dataplan

You should go to someone you know who's got the same ISP than you first, try it there. If it works it's your router, If it doesn't it's you ISP config that's creating a IP conflict with your device.
