Hi all.
A per my post in this thread. http://forum.xda-developers.com/showthread.php?t=1117077
Code:
Hi all. I also have weak signal problem as well as fon router issue. The signal strength isn't as bad as being mentioned above, but still could be better.
But with my fon I can connect and connection is as showing connected, but I can't browse or have any connection to Internet whatsoever. When connecting to fon both lights on the router start flickering like normal and once connected when browsing or going to market for apps just one light blinks, when both should under normal activity.
Also I get this error message " a network error has occurred. retry or cancel and return to previous screen." when I try going to market.
I've tried setting security to none and wpa and still same no net.:confused:
Now some personal thoughts with experience with Linux and wifi. I think the problem is with driver or the firmware of wifi card on GS2. I had netgear card even thought it was claimed to work with Linux it kept on overheating and dropping connections with weak signal and every time I had to patch it to make it work properly, Many have reported same issues with other devices with Linux when it was claimed that devices should be working but were not.
My question is there anything I can do other than I haven't so far to check the problem why am not getting Internet through my fon router? Or any other checks I can do other than wifi tools I downloaded?
Thanks

Thats the router not the phone .
Set router to no security or passwords .
DELETE ROUTER WIFI FROM PHONE REBOOT AND RESET UP WIFI .

Hi, I've tried that still the same problem.
And it's not the router since every other device connects to it and many laptops and computers, without any problem.
Like I said I've tried it with wpa wep and no security just open, and still no Internet, even though it's showing as connected with signal bars at the top of the phone.
I've tried the phone with friends routers and it works on those. But not with mine which is Fonera.
Does anyone know what chip is used for wifi in these phones?
In case anyone else is wondering it's Samsung's own brand.
manufacturer=Samsung Electronics
device_type=1-0050F204-1
OK so I have T mobile version Galaxy S 3 phone is rooted (stock ROM)
WiFi was working properly except that sometimes when I had few devices connected to my router it didn't want to connect , but I have always experienced that problem with android on my HTC Evo and My touch 4g, it seems that when you connect to a router and disconnect and another device connects the phone tries to connect using the old IP which is now used by the other device.
its annoying but biggest problem now with the S 3 is that 2 days ago the phone will connect to the router at least it shows the WiFi icon on the status bar and on the wireless and network info ( connected ) but once I try to open a web page or app like Facebook it will show no connection, Kies air doesn't even recognize that there is a WiFi connection.
I have tried looking around on this forum and on google and have seen other people with same problem but no solution at all.
any ideas anyone?
I have tried forgetting the connection, restarting phone router, modem.
and other devices including my old phones work.
If your getting the same problem with different phones then the problem must be with your router. It seem that it only allows a certain number of devices to connect to it.
No, other devices and phones are working properly, problem is only on the SG3 100% sure not router problem at all , I am thinking something about the WiFi info on the phone got corrupted or something I guess I will try factory reset and wipe everything.
Well for future references, I had to do a full wipe ( data, dalvik, cache) and its working now as intended.
anyone experiencing this problem with galaxy s3 wifi connection after I reset my device it started working again but now after a few days the issue is back, have Wifi ICon on status bar but no connection to the internet at all, this is only happening with the S3 , evo 4g , mytouch 4g, laptop and desktop work without any problems.
Ok finally found the solution without the need of resetting the device. had to use static ip on my phone...
long click network connection , modify network config, show advance options, "ip settings = static" assign an ip and if u need help finding other info as gateway, dns servers etc..
on windows run "cmd" and ipconfig /all
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?

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.
Hello all,
I have a really annoying problem, I had no problems with my phone on 5.1.1. but after updating to 6.0.2. opening webpages or sending images in IM's (Whatsapp , FB messenger) is too slow, more then 30seconds to upload a photo. It works perfectly on mobile network, only having problems with WiFi. Tried different WiFi hotspots, tried deleting WiFi network and connecting again, even did complete phone wipe.
Any suggestions or ideas how to fix this?
You might have had wifi and mobile sharing data(if wifi is slow or no Internet connection, mobile data would take on some of the stuff you're trying to load.) on previous android and that's what's given you the boost previously. Check your ISP has throttled your connection (over usage data). Make sure it's just your device using the Internet for the time being, cross check IP with phone and also check your DNS on your router. Your ISP could be experiencing technical difficulties also. Also cross check any other variable that may make your connection slow (I.E bad weather, steam downloads and anything related to your modem before we get to your phone
Mobile data sharing is off. Boost is also off. I said I tried multiple WiFi hotspots and it is still the same, and this started happened immediately after the update so I am 100% sure it is not my router or ISP (I have no problems with connection speed on my PC). Also I did ruled out everything before posting, so this is definitely something that update broke.
