Hello all,
I flashed cyanogenmod succesfully, did the wipe n all, and my wifi works for browsing the internet, but when i try an application like teamviewer, it only works trough 3G data connection. Same thing with Sygic mobile navigation for downloading maps, 3G works, but wifi doesnt.
So i can get a connection with my router and use the internet, but wifi works with limitations, anyone have a clue?
grtz
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...
The proxy works fine for using with the browser, facebook twitter etc but i dont seem to get any notifications whilst it is in use ie: connected to wifi all day at work but i get no email, fb, whatsapp msgs, as soon as i turn off wifi and am back on data connection everything comes through at once. I can use al these apps fine though through the wifi. E-mails occasionally come through on there own accord, but more often than not they dont.
Anyone else have this/got a fix?
Currently using Slimics 3.8 with fluxxi kernel
First of all I know that grey means not connected to google servers so the problem is this:
When the screen is off and idle(no data transfer activity) for 10-15mins it will lose connection to google servers without fail despite full 3g signal bars, resulting in push messages not being recieved until I wake the phone and the connection turns blue again.
And this only happens on 3G/H+, wifi has no such problems
Anyone faced the same problem and have a solution for this? Have tried different modems, kernels, 3G only etc.

Check under Slim settings to confirm data management when screen is off is not enabled (under power)
Swyped from my Galaxy SII
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.

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.
