Can no longer turn on Wi-Fi - Galaxy S III Q&A, Help & Troubleshooting

I can no longer turn on Wi-Fi on my SGS 3. The icon either just stays grey or sometimes goes a dark shade of green for a while before turning grey again, but it still doesn't connect.
This began after using this app to restore my passwords:
https://play.google.com/store/apps/details?id=com.ryanamaral.wifi.passwords&hl=en
I've deleted the app, done a factory reset, cleared cache, tried WiFi manager apps, but nothing works.
I haven't changed the firmware, I'm on EE with the following 4.3 firmware:
Baseband: I9300BVUGNB2
Build: JSS15J.I930XXUGNB5
I hope somebody can help, phone is nearly useless to me without WiFi.

Wifi is kernel related flash one of the many stock kernels in the forum or flash another stock rom .

Thanks. I'll try a custom Kit Kat ROM. Is there one you can recommend?

[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] In a huge pickle

I accidentally factory restored my phone this morning. But that is not the pickle. At the end of the initial account setup, the phone force closes the setup. And after that I don't see anything on the screen except for the notification bar. I can work with the notification bar that is switch on/off GPS, data, etc. But rest of the screen is black. Since the screen is black, Cant access any setting and toggle USB debugging to use KDZ. Can get calls and use the settings that come up there. But I guess that's about it. I think this is happening cause the option to setup Google account don't come up during initial setup. What can I do? Any ideas other than going to the service center?
did you had a custom rom installed

i has the same problem and make a reinstall with odin, and every thing is working nice although a did some test with a firm of argentina (I9100AROLP4) and this one are perfect.:good:
Just root your device and change your kernel can save your problem.I hope so.
Known problem; http://code.google.com/p/android/issues/detail?id=28036. Rooting, installing Fardjad's WiFix, setting a country code (GB in my case) and increasing /proc/sys/vm/min_free_kbytes from 3606 to 16384 fixed it for me. None of that should be necessary on the stock firmware of a consumer appliance, though.
EDIT: Actually, if WiFi connects, it might not be this issue after all. It is a problem in many (all?) official ICS 4.0.3, though. If by "internet is still not working" you mean the stock browser force closes before you can do anything with it, you'll need to go into settings->applications->all->[browser name] and clear cache and data. You'll lose your bookmarks, history and cache, so back those up first if you want to keep them.
Hi , I updated to this same build version today (form the first post), and I did notice that the wifi is working, however the download arrow of the wifi icon on the notification bar keeps blinking all the time. Is this normal?

Are you on about the up and down arrows on the Wifi icon? This is normal this just shows the up arrow as uploading and the down arrow as downloading data. All part of the ICS UI.
Piece of advice root your phone install custom kernel and Rom. You will not go back to stock ever again!!!
Thx for the reply. Yes those are the arrows I'm refereing to, but the thing that seems odd is that whenever the wifi is connected the down arrow keeps blinking regardless if I'm using anything (apps or browsing) on the internet or not.
As for the custom roms/root, I will get to those yet.. First I'll try rooting and then I might move to a custom rom. I actually got very used to the stock rom, but I know once I start changing it will be a one way road.. lol
regards
I had a similar problem when I updated to ICS 4.0.3. I did a factory reset on my router which sorted it out.
Sent from my GT-I9100 using xda app-developers app
In my case it doesn't seem to be draining more battery, its just the blinking that I found curious...
Not sure the router has anything to do with it but I will keep this in mind for possible fixes...
thx

Your Wifi always looks for the router hence the down arrow downloading data which is very minimal. Your router gives you an IP address which lets you have internet. Your wifi checks for internet even if you are not using it. This is why its best to turn wifi off if you are not using it as it does drain your battery. Custom kernels have sorted this out when your phone "sleeps" it doesnt wake up even if your wifi is on.
Root first, Backup backup backup second, then install a custom kernel (this is the most important part of the phone) and then a custom rom. Seriously stock hasn't nothing on Mod. Think about it.....

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!

[Q] Samsung Galaxy SIII (GT-I9300) International Crashing And Rebooting

Hi, I'm having a curious problem with my S3 and I've been unable to solve it. I watched the "noob" video and tried searching these forums as well as a google search with various combinations of the wording for my problem. Nothing matching my issue turned up, I hope I didn't miss anything.
I recently bought a S3 second hand (yes, i know, i should have known better). It was rooted and running some kind of custom ROM when I first turned it on, but I was willing to deal with it until I double checked the procedure for getting it back to stock and starting again myself (nothing against the original rooting and flashing, just like to know exactly what I'm running).
When I purchased the phone I obviously checked that all of the main things worked - calling, texts, mobile data, wi-fi etc. I get home and connect to my home wi-fi and start checking things out and setting stuff up. The phone randomly rebooted. I carry on after the reboot and about 10 mins later, another restart.
To cut a long story short, there is something wrong with the wi-fi. If I turn off wi-fi in the settings menu and reboot, everything works great. No crashes, no reboots. If however I enable the wi-fi about 50% of the time it will crash while wi-fi is activating. The other 50% of the time, it will crash as it goes into the screen lock (either via timeout or pressing the button).
I've re-flashed to it's stock version of Android (using the 'Samsung GS3 Toolkit and Odin), same problem. Anyone got any ideas?
Thanks in advance
You can try updating the modem and RIL to the right version for your country, search in general forum. If it still reboots then try with another wifi source - I've seen some routers cause problems on client machines.
If you do a factory reset when you flash the modem, plus you have the latest stock ROM on board, then any remaining problems are probably hardware.
Test it fully after the factory reset, before you add any apps etc.

After much experimentation and flashing of various files to my phone I have further narrowed the problem. I've still not solved it, but getting closer I feel.
After a clean ROM flash it works like a charm regardless of how much i use the wifi etc. It's only after the first reboot that the trouble starts. It will begin randomly restarting. If I perform a factory reset from recovery mode, it works again, but starts resetting again after a reboot.
Any ideas?
