[Q] Help My SGS II has a weird Wi-Fi Problem - Galaxy S II Q&A, Help & Troubleshooting

I have this problem over a month and I couldn't reach the solution yet I did everything I know but still
the problem kinda weird one , is that when I turn the WiFi on its works excellent for seconds then all of a sudden I can't browse anymore and only by turning off and on I can browse again for few seconds
I did a Factory reset but no benefit. And I tried to change the rom to Full 4 files (Pit,PDA,Phone,CSC) official rom and Still the same thing
I found the similar issue on the internet without any solution
What could it be?! I'm Afraid Its Hardware problem but why!
Any suggestion
Thanks in advance.

As wifi is more or less kernel related, you should post your kernel version.
Maybe flashing another ROM or kernel can help to solve this wifi issue.
Have a look at Intratech's Official Firmware thread here => http://forum.xda-developers.com/showthread.php?t=1075278
Download and flash the latest ROM for your country/region/carrier or just the latest Frankenstein ROM (XWLA4, I am using it right now).
Just wipe cache after flashing the ROM via recovery mode (shut down the phone, then press Volume UP + Home + Power button until recovery menu appears).
Good luck !

[Q] WiFi Error, not allowing connection after Litening Rom installation

Hi guys
I recently put Litening Rom 1.5 on my SGS 2.
Prior to this the WiFi was working fine and I believe shortly thereafter (can't be sure). Now though the phone defaults to 3G. Under Settings > Wireless and Network > Wi-Fi settings the Wi-Fi box is unchecked with the word "error" underneath "WiFi". Whenever you try checking it, it says "turning on" for about 10seconds before returning to "error".
Anyone else experienced this or any suggestions, all pointers very much appreciated?
Thank you
flash back your CF-Root and your wifi should be working again...
Will try that when I get back home.
Does this mean though that I can't have Litening 1.5? I've not heard of other people experiencing this. The file I oriinally downloaded had 4 parts. Three were pretty obvious in terms of where to sync with Odin i.e. had CSC in the title, TAR file and one called PIT. However, I presumed I should insert all 4 in the relevant boxes of Odin. Was this wrong?
Thaks for the advise so far.
no you can use litening....your step is correct...just try to flash back your cf-root if u using for rooting.....
btw couple of user have same problem in which after flashing modified rom sometimes the wifi not working....so when they flash back cf-root kernel, wifi works again

+1 for me. reflashing kernel worked fine
Hmmm!
Well the good news is that reflashing the CF Root worked and I got the WiFi back again. The bad news is, that when I put the phone down and picked it up again 20 mins later, it had gone back to it's old bad habits.
Tried reflashing CF Root again but this time no result.
Looking through the phone I'm wondering if it could be either a confliction between system operations or a dodgy app (less likely this one).
The reason I say this is because at present I have to ways of quickly turning Wi-Fi on and off. 1 is the swipe down action from the top of the home screen, which gives the Litening Blue toggling buttons and the other is residing on my 2nd home screen which are the green toggling buttons which were their before Litening. I could be wrong but both with the problem occurring are not illuminated. Attempting turn WiFi on only illuminates one of these temporarily. Therefore just wondering if on is cancelling out the other?
What would you suggest trying next, perhaps Villian Rom incase it's a Litening thing? If not, any other setting I should try adjusting both on the SGS2 or in Odin etc
i believe your issue is down to installing a corrupt rom...why i say corrupt coz you didnt clear the calvik cache, wipe data when flashing the room etc...well my advise is to start everything from fresh..root your phone with CF-Root and boot in CWM mode..follow the basic step
start clearing cache, wipe data etc and install back the custom rom. or you may try back with official rom see if u face similiar issue...
another option is to upgrade / downgrade your baseband modem....i'm using XXKF2 which is the best in my setup in my country, signal more stable and good connectivity compare to KE7...some user in different country prefer KE7.......coz they got issue with KF2
Thanks Gchildz for your continued assistance.
Ref stable baseband modem what would you suggest in my case: I live in the UK but spend much of my working time in Europe, Middle East and former Soviet Republics? I appreciate that residing in one country would be much easier to determine the baseband but as a frequent traveller, is there a baseband that is all things to most of the places mentioned? To be fair, most of the accommodation is in the middle to upper end of the spectrum and therefore they WiFi I'd be using would usually be setup by an independant company with a reasonable budget, rather than a flee pit hotel with a cheap and nasty router.
Follow-up
Further to last, it would seem that I'm really not having much luck with this.....
I reinstalled CF-Root, then flashed to Villain 1.4 and still the Wi-Fi is not working. I even put on top the optional Modem file and again nothing but this darn "Error".
If I could, I would change the original thread title to "Error msg when trying to turn on WiFi" as it would appear to not be peculiar only to Litening now.
BTW Regarding the corrupted ROM I did clear the cache, factory reset etc 100% this time around. I thought I had last time but could be 100% posititve. I'm using Odin v.183, that shouldn't make a difference should it?

[Q] Wifi Problem !

Hey guys !
To begin with, I have searched and searched and have not been able to get help.
Phone stats :
Model GT - I9100
Android - 2.3.5
Baseband:
XXKI4
The problem is, I turn on wifi, it scans, then turns off. I have tried adding a wifi and it comes up "unable to save the network".
I got this phone 2 days ago from a friend.
Mac address and IP address are listed as "Unavailable" in advances settings.
PLEASE HELP!
Tried a hard reset?
Thanks for a quick reply !
I have tried:
Power button and home button (holding)
Factory reset. (Home + Power + Volume up)
Are either of them classified as a "hard reset"
I'm sorry, I am very new to android and have just moved over from apple. Not looking to go back just hoping to clear up this issue !
Yeah, that's one way to do one.
You should try updating your device. Your firmware is pretty outdated.
Either with KIES (crap software, but simple - you know, just like iOS ;-) ) or Odin/Heimdall (little harder, but works for sure).
Tell me if you need help.
Hey, updated to ICS using odin after researching all about roms and kernals and what not.
It did fix the issue of the phone constantly in a loop of turning itself off (HOORAY). Wifi is still not working
Then try a Rom that isn't based on Samsung's. Flash the resurrection edition of CM9 via Odin and after that the latest nightly via cwm. It's worth a shot, as CM comes with its own kernel and such.
If it's working under CM it was some sort of software fault and we can try to figure it out (unless you want to stick with CM).
If it doesn't, it looks like a hardware fault and I cannot help you.

[Q] wifi problems after rom flashing

Yesterday,after I flashed stock ICS rom through odin, I noticed that i can't connect to any kind of wifi connection, even wifi sharing from other devices! it says just "obtaining ip address" and nothing. stuck like that forever. What?

My problem was unable to turn on wifi, wifi stuck at the stage of turning on.... and forever like that cant off and on.
Most probably is hardware problem coz i have tried many ways to solve including flash back to stock rom,change modem,change kernel and etc.
good luck for you,hope you are not the same problem with me.

Wifi is kernel-related.
So, try to flash another kernel to test.
Or if you don't want to flash another kernel, check in menu Settings > wifi > (menu button) Advanced > Use static ip.
Try to enabled and connect.
Then disable and try to connect.
If that does not help, try to wipe cache (and Dalvik cache) in recovery mode.
Press Volume UP + Home + Power buttons as long as the recovery menu appears, then select wipe cache and reboot the phone.
P.S.: Check the configuration of your wifi router / WLAN access point, that is allows your phone to connect.
ok so i did everything again just to be sure and... my mistake! the problem starts not after the rom flashing but after cf root! have i done something wrong maybe?
I would say look for a custom rom that is already pre-rooted so then it should have all bugs to do with wifi removed.
I used to have a problem with the wifi myself which caused problems when turning it into a wireless hot spot and then wouldn't turn back off again.
But now im on the Custom Rom I am having no problems with wifi at all.
Hope this helps.

Actually, I would say try a different kernel. CF-root is a kernel. Wifi drivers are in the kernel. Ergo... ?
Wifi is kernel related issue
try changing your kernel
you mite wanna chk dis

may have something to do with the root. my phone had this issues once. just flash your phone with the correct rom and do NOT root it again as it may have something to do with the root itself. or just something got messed up during the rooting process

GS3 Freezes after disconnecting from WiFi

I recently flashed CWM onto my uncles GS3 and rooted his current rom. I made a backup and then tried out a new AOSP rom, which we decided not to keep because my uncle did not like it. But now, returning to the old rooted stock rom, every time the phone disconnects from wifi, it completely freezes up on the lock screen. Pressing the lock button does not shut off the screen and instead just locks it. You are unable to unlock it as the phone completely freezes up. The only way to get into the phone is to double tap home to get into the voice commands, and then go to home from there.
But even after that the phone continues to freeze. I tried another ROM on his phone today, but the problem still persisted a while later. It all happens when the phone is connected to wifi, and you walk out of range. After which the phone starts to freeze up.
I'm totally unsure whats going on. I just flashed the rom again, and we are trying a clean slate with no restoring of any data. It may have started to happen after we installed root browser (just as a guess), but we could be completely wrong.
If this continues again on this rom as well (which is Revolution HD) Im going to go back to completely stock (rom & recovery), and hope it still doesn't persist there. If not then I am out of options, and I have no clue what to do.
Any help would be GREATLY appreciated. We spent so many hours today trying to resolve this.
Thanks!
Usualy WiFi problems are kernel related. Have you tried Siyah or another custom kernel?
If this will not help than returning to stock with all wipes is the best idea, this should resolve your problem. If not, than you can try to reset router or set static IP for s3. Also try to remove WiFi setting for your home network in the phone and set it again manualy or via WPS mode.

Thanks for the reply. This issue has been occurring between two different roms, so can the kernal still be an issue? Its happened with the absolute stock rom (w/ root) and Android HD Revolution.
My uncle said he would play around with the phone and let me know if it freezes again by tomorrow. If it does im going to wipe and stock.
Can anyone show me where to get the stock roms for the i9300?
I've downloaded and tried 3 different ones, but the phone never manages to boot up!

Same problem on Galaxy Note N7000, did your problem resolve by reverting back to stock because I've tried every possible option, to no avail?

Go into recovery and wipe the cache, I believe that was my problem.

After 9 mo, starts freezing and rebooting itself...

I have i9300 w/stock 4.1.2 rooted. The last few weeks, it started freezing and sometimes rebooting itself. Sometimes it will freeze and not respond with lock screen on. Sometimes it will not respond to pushing a button to wake it up when screen is off. In the beginning, it was once a week. Now it is once or twice a day.
Has anyone else experienced this? Any suggestions?
Thanks!!!!

I can link you a quote about the freezing

The phone freezes when writing data to an affected eMMC block.
An eMMC block is affected, when it's internal block pararameters (as f.e. write count for that block) are in such a state, that these parameters trigger a corrupted block without SD-fix (4.1.1) or trigger a freeze with SD-fix (4.1.2).
When a phone is hitting an affected block with a writiing operation is completely unpredictable.
So these freezes can occur on almost each situation on the smartphone when it writes data.
But you have indeed a higher chance to trigger a freeze when writing much data.

Here is a link to that tread click here
If you don't like the freezing i would suggest to flash a stock rom like MB5 or something newer many people reported that they newer had freezing with those roms including myself i used MB1 , MB5 and MC2.
Instruction on how to flash a rom (THIS IS ONLY FOR GT-i9300 International S3 model)
Instructions For Flashing Firmware:
1. Download the firmware (download I9300XXEMC2 here provided by Faryaab)
2. Extract the firmware only once when you get a .tar file don't extract it any further you should also have another file there a small one named something like SS_DL.dll
3. Open the included Odin (click here to download uploaded by Faryaab)
4. Turn off your device
5. Put your device into Download MODE (Home + Volume Down + Power)
6. Connect your device to the PC
7. Click PDA and select *.tar.md5
8. Then finally click START!
When its done your device should boot normally but its recommend that you wipe data and cache for best performance (this will reset your device)
9. Put your device into recovery mode (Home + Volume Up + Power)
10. Chose wipe data then wipe cache and then chose reboot .
Here is the original tread were i got the firmwares and the guide click here
What is strange about my experience is that I never had it at all before a couple of weeks ago. And now ... Nothing changed except perhaps a couple of new apps.
Hummm....
Try a factory reset first.

I linked you a tread about the issue , the bug is in eMMC and the phone dies after about 9 monts but as you have an early 4.1.2 rom with a bug fix that prevents it from dying it starts freezing but the rom i suggested should have a newer fix that doesn't involve freezing . I installed the newer roms because i feared my device was going to die and i don't have warranty , also factory reset should help you but it would only last a few days if you have the SDS issue then it would start freezing again. If you have warranty on the device then stay on that rom and hope your phone will die so you can get it to samsung to fix it for you or you can flash the newer official samsung stock roms and hopefully get rid of the freezing .
Sorry for my english i learned it by playing mmorpgs
