Can't find WIFI - Galaxy S III Q&A, Help & Troubleshooting

Hi guys
My phone was running great until i bumped into this problem. It seems like my phone can't detect any wifi anymore, the list is empy when im in the wifi settings. i've tried to factory/hard reset my phone but the problem is still there, i've also tried mega wipe but that did not make any difference.
There is nothing wrong with my router beacause i have other phones connected to it. I tried to connect to wifi at my friends home but still, no wifi :/

maybe try a different kernel and see if flashing it fixes that. Or could it be that you switched the Wifi settings somehow to only detect wifi networks in a certain m/ghz range 2.x vs. 5?

Well i've tried to flash a different rom and that includes a different kernel,right? Well alot of my little cousins have played around with my phone so that could be possible but how do you change the settings to its standard? as mentioned i wiped my phone back to stock, shouldn't that have reset all my settings back to normal?

well yeah it should have reset it to stock settings. You can check it in the Advanced WiFi settings though.
What kernel do you use and what rom btw?

I would through recovery format cache system data and sd card .
Then flash your original rom .
Fails its hardware .

[Q] Samsung Epic 4g wifi won't stay enabled

First of all, I am new to all things Android. I just got my Android phone about a week or so ago. I also don't know if this thread is in the right spot...
I just rooted my Epic 4G and the wifi won't work. I have no recollection if it worked before I rooted it since I never used it. All I know is that when I try to enable it, it says it's searching for a hotspot, then after about 10 seconds, it disables itself. I tried a third party app from the store, and still no luck. I think the chip might be fried...
I am running Android version 2.3.6.
I rooted my phone using this method:
http://forum.xda-developers.com/showthread.php?t=1265429
I followed the steps exactly.
You could try flashing a new rom.

Flash this kernel then: http://forum.xda-developers.com/showthread.php?t=1269437.
What will this do?
Also if I want to go back to the default kernel, how would I do that?

random reboots !

Hello everyone !
my atrix start gets crazy... when i turn it on, after 5 seconds its got reboot.
and the battary precentege is going from 100 % to 40 % after the reboots..
what i should do ?
thank u :good:
Did you try to change the kernel? Sometimes that helps, in my case for the GB based roms i solved it that way
Hi
you don't say if you have changed anything recently (eg installed a new rom).
What i would recommend is you go into recovery and wipe your cache, reboot and see how that is.
If you have your current rom on your sd card then reinstall it (no need to wipe data)
If you have installed a new rom, try to go back to a more stable one that works for your phone.
good luck
i try waht you said and its not helping..

Stock ROM, or custom ROM? If it's ICS leak based, that's your problem.

Well it can bee battery or WIFI/BT chip. You can check does your wifi an bluetooth work if they doesn't work or provide error mesages then your chip has burned out and you need to delete WIFI/BT driver or check does whit other battery your phone work.
But maybe it can be solved whit just factory reset and wipe caches in recovery. Hope that this will help you.
P.S.
If you can't check your phone whit other battery you can use factory cable, and then battery isn't necessary.

You can tray this rom: http://forum.xda-developers.com/showthread.php?t=1656760 where wifi/bt driver alredy is deleted but you can use other rom and delete dhd.ko file. It can bee stored in different locations and whit different name for different rom:
/system/lib/modules
/system/lib/
or for example in ICS leak rom /system/lib/modules/bcm4329.ko
But if you can't do it just upload rom somewhere in internet share link and I will modify it for you.

maybe you need to flash a new modem. ask someone in the 242 who has a i9100 what modem they are on *#1234# to check and flash that modem.

I have tried different builds higher than 6 and same thing happens. Installs fine and have service for 2-3mins then off again. This is frustrating because after that then i have to reinstall the same old ROM and reinstall all over again. I've tried 4.3.build.1-OFFICIAL-909 thinking that maybe if i change from 4.2.2 this would solve my issue but still the same thing.

There's no 4.3 official. Try stock ROM and see how that works out for you and let me know.

did you try to run any battery stats app? (e.g. Better Battery Stats if this still works with 4.3) That way you could identify what keeps the phone awake.

did you try another custom kernel like googy etc?
to be honest I am not sure what to suggest more, maybe a full clean wipe, or maybe have a look in the boeffela thread?

[Q] WiFi connected but not working

Hi all,
I have a strange problem that i can't seem to find elsewhere, another wifi one. I am connected to wifi and it shows that i'm connected and shows send/receive arrows. When i try to do something that requires wireless it is like i am not connected even though i am. I have had this problem before and a factory reset or 2 (or 3) normally fixes it. this time i can't fix by factory resetting. btw, i am rooted using cyanogen mod version 11.0

You could try flashing a different modem on your phone or update or change the rom. Since it works after a few flashes, we can rule out that this isn't an issue with your router.

i only rooted last week with cyanogen mod. Isn't that changing the rom? it has had problems before and after this. I have a feeling it's hardware.
Just did some more research on i9100s and wifi... seems to be many problems. Could it be the leaky battery on the main board? i would have thought that would have completely disabled wifi but maybe not

I doubt it is a battery problem. What I meant was to update to a newer (snapshot) of CM11 or try a previous version of android (4.4.2 or 4.1.2).

If I were in you I'll try to flash CM11 again and then checking if the problem depended really due to CM11. I did not ever have wifi problems on that rom.
Sometimes could be your modem/router not connected to the net but your S2 do to it...

Defiantely not router as other devices were connected and working. Flashed CM11 the other day. I did sone further research and it appears that whatever controlls the wifi gets corrupted and reflashing the rom fixes this. All good, have a backup now so fixing this problem is now a 10 minute event rather than mindless resetting for an hour.
