I had the same problem when I switched from a 16gb to a 32gb version.
I restored a backup but couldn't connect to wifi. A factory reset solved the problem for me but I see you've already tried that.

The password you entered is correct and the Fritzbox isn't using any MAC filter i assume?
Connect your phone to the computer and open adb shell
Kill any process named wpa_supplicant and type:
Code:
wpa_supplicant -dd -i wlan0 -f /sdcard/wifi.log -c /etc/wifi/wpa_supplicant.conf
Then attach the generated logfile after having tried connecting to a wifi network.
Alternatively you can run "wpa_cli" and show it's output.

No i tried everything now but still not working! So i explain my router is down stairs, i am on the second floor! He sees my network but can't connect saying authentication error! When i go near the router about 3-4meters it connects to my network and i can access the net without problems! Now i am at my friends home and my galaxy s3 connects near the router but when i go in an other room it remains connected to the wifi but no internet connection an after a while he disconnects automatically!
I suppose if it where an hardware problem it wouldn't find the network at all or am i wrong with that?

Well it sounds like Wifi power management fails.
But please, respond to my last post by executing:
su
wpa_cli
And then connect to the wifi network.
(Wifi must aleady be enabeld but not connected for it to work)
Then post the output
After finding that another location WiFi was also not working I wiped phone flashed stock rooted restored Nandroid . Result works but yet to test sleep and lose WiFi problem if its still there.

i have a problem with my mac adb-shell can't access my galaxy s3
now i'm trying to download the stock firmware and flash it with mobile odin!!!! hoping that this works
ok flashed stock firmware with full wipe and without root but no luck!
now i'm thinking it's an hardware problem!! but the strange thing is that it has happened after installed omega 9!!!
No one had solved this problem?

Are you able to try to connect? Mine will have a notification for open wifi networks found but when you click it only the networks restored show up - and only the networks restored are all I can connect to.
I don't know about you, but this is BY FAR the worst Android device I've ever owned, perhaps mine is defective. I was out of town 9 days and couldn't return it and they won't extend it 3 days to take it back. This is about 20th Android device and the first that I truly hate. It drops calls FAR more than my other phones (all Sprint, so not network, 5 lines).
i am very happy with my device!!! the unique problem is the wifi!! i think it's hardware!!!! here in luxembourg it takes more than 15 days when you give it to the warranty!!!! ;( that's driving me crazy

When i try to run
wpa_supplicant -dd -i wlan0 -f /sdcard/wifi.log -c /etc/wifi/wpa_supplicant.conf
it just lists the help without telling me what it does not like. I have tried lost of variants based on that help text as well. The interface is wlan0 and the conf file is named and located as detailed.
wpa_cli
does not exist.
I have been fighting with bad wifi for over a week. I have tried countless wipes , factory resets , format partitions , odin's to different ICS stock roms including bootloader and even wipe efs on occasion out of desperation. Power saving mode does not help, and I have tried about 15 different access points.
I think at this stage its hardware, but don't have a spare phone to use while it goes for repair. Got one lined up to borrow, but it wont be available for a few weeks. So in the mean time i would like to dig further. Currently on the latest Jelly Leak. But the issue is there on all roms. I'm happy to flash something else if it helps with getting some logs.
Any pointers or ideas would greatly appreciated.
Thanks

When wifi is connected some times internet does`t work, said conection problems, I turn off and again on and it`s working for some time, then again conection problems. Anyone have same problem???

Does your wireless internet connection have a password?
If so is the password entered correctly?

Maybe you could, let the phone forget the connection (delete it) and then try it again.

restart your wireless router or access point, see if that helps!
Maybe you have the wrong modem.

i think this is a kernel issue coz of the rom installed!
try reconfiguring ur router but after forgeting the network on ur phone and c how this works out!
My phone has had this problem since new. It stayed through stock firmwares KE1, KE2, KE7 and KF1, and has also occured through all Lite'ning Rom versions. I notice it's happening to users of a number of other roms, but isn't a widespread problem.
I have tried reconfiguring routers and forgetting the connection, but the problem persists. Very annoying, but not enough for me to send the phone back to the UK for repair (I'm in New Zealand!).
The problem is not resolved under the leaked 2.3.4 either, I've already heard of someone with the same problem on the 2.3.4 version of DarkyRom2.
Edit: Wifi is set to never sleep. Even cycling through this setting does not help.
those who have problem with WIFI try to reflash back your root application like CF-Root...then your WIFI should be working again...
My model is YP-G70 , firmware 2.3.5 on original updated stock rom.
My wifi working very well when I used with my others device (HTC Desire, Nook Color and PC) but with my awesome Samsung Player...
Every some minute the player drop the wifi line and after 1/2 second reconnect.
And i loose my download
Incredible.
I turn off Juicedefender, I 've setup the wifi property "Wifi sleep policy" with NEVER, I turn on KeepWifi Service (app) but.. NOTHING.
Do you have some advice?
Help...
I had the same issue when I bought my US model. But I only had the issue with my home wifi and not anywhere else. Can you connect at another location and see if you have the same issue? I ended up just replacing my old Belkin router and haven't had an issue since.
Sent from my YP-G70 using XDA
Try installing KeepWifi, see if that works. Otherwise it could be your router configuration, like the kind of encryption you use for your wifi password. Try to reset your router but don't use any password for a little while, if that works, use another encryption method.

Solution
I've changed the "Client Lease Time" in my dhcp server (ddrwrt) from 0 to 99999 minutes.
It's working end I don't know why
I read this solution in an old XDA item of this forum. Thanks!!!
Hi
I have the same problem with my G70. For to have the max signal in the device i need to go beside my router. I have try with other router but the problem is the same.
maybe is only the display animation in the screen? I say that because i check the quality of my signal at it tell me GOOD.
im also having this problem on my I9003.
the wifi sleep policy has a bug.
some say that your Security/password should be WPA or WPA 2, they said this happens on WPA-secured routers, i haven't confirmed it though.
the only temporary solution for this is to disconnect or turn off the wifi in your phone settings and turning it on again, then you can connect again.
Due to the ROM,i think.Because wifi on 2.2.1(mine is YP-G1) functions great
Dose G70 have a ROM of 2.2.1?If so,you can try it yourself if you like
well i found a fix for this bug, just download the latest version of WiFi fixer from the Play Store.
that's the easiest way to fix this wifi sleep bug.
Hello, I am having the same problem, but I suspect my situation is worse. I've even tried the wifi fixer app, but my 5.0 drops wifi and breaks large downloads and games that require constant connection.
Do I have a defective unit? Any advice and help would be much appreciated.
Solution! (for me at least) go into your router settings on ur PC and change the lease time to either Forever or 30 minutes ( I can't remember which one). It worked for me... good luck

I had this wifi problem with 2.3.5 it was really annoying . Even if i was a meter from the router the signal sometimes dropped to 1 line. Samsung fixed this problem with the 2.3.6 update, and now the signal is ok.

Not the best solution, but....
I have the same problem that happens with my SGP 5, my friend's IPAD, and the Actiontec Router that Verizon supplies with their FIOS service.
I've tried every other remedy that I can find with no success.
The only solution that works for me is to assign a static IP address to the devices. It results in a very solid and stable connection in both cases.
Hope this helps someone else !!
Thank you all for the advice, but nothing seems to work, and I have no idea how to force it to upgrade the os from 2.3.5.
I don't know what to do now short of sending it to Samsung for service.

Download from samfirmware (or anywhere else) the XXKPL firmware.If you are 5.0 international, simply flash it with Odin. US users must make a new tar with just the "factoryfs.rfs" in it and flash it with Odin. That will upgrade you to 2.3.6. However, if you do that, I strongly recommend installing one of the custom kernels, so it won't be impossible to root.

wifi direct
Im having another problem with wifi but its with resurrection rom 2.3. Donno how to configure wifi direct or what explorer to use to send via wifi. All i can find is a tick box that says wifi direct.
I'd flash a stock ROM. Then you'll see if its a problem with your current rom or not.

Yeah, I've had same kind of problems with a stock ROM. Now the WiFi has been working just fine but sometimes I had the same problem as you do. No idea why it does it.
I have a not rooted galaxy, and I have the same prob. It mostly happens when you turn on/off wifi directly from settings instead of going to settings --> connections --> wifi etc. (ics feature)
I solve the problem with rebooting my phone...
Only takes 30 seconds.

Hi, Thanks for your reply.
Can I ask what you mean by a stock ROM - do you mean one that is not insecure rather the original?
I fix it by turning airplane mode on and off. But it doesn't occur after I changed to a custom rom

Hello everyone i faced the same problem and solved it by an app called wifi fix which is made by amid M Geha :good:
sup everybody.
firstly, i am a wireless expert (11+ years experience) so im not a nuubie to Wireless networks.
but i am new to Android and have just recently gotten an S3, so im hoping some body can help me.
i have an 802.11n wireless hop that connects my upstairs network to my downstairs network (internet router is downstairs)
upstairs i have an 802.11b/g access point for the older devices to connect to, this access point is connected to my 802.11n bridge
my laptop connects to the 802.11b/g network fine, and has internet connectivity (no issues)
when i first got the S3 last night, it was connecting fine as well, but since this morning, no matter what i do, the S3 connects to the access point, gets DHCP, i can ping the IP address, but it doesnt have net access, but if i connect to the 802.11n network it gets net access.
so for the life of me i cant figure out why.
so in a nutshell net access works from the laptop, but not the S3, same access point, and yes ive checked the WPA2 passkey, and the device is getting DHCP.
any suggestions.
like how to reset the IP address on the S3

Sounds like the default gateway route is not correctly received or activated. Do you have any computer/laptop with a promiscuous-capable Wifi card around that you might use with Wireshark? It should tell what exactly goes wrong.
Since you claim to be a Wifi expert I guess you won't need much help interpreting the result.

Try shutting off ur router.... Wait for a min or so then turn it bak on nd see what happens. I have an intellinet router which when the current goes off nd then on im able to connect to everythng except all google services (gmail, search, reader, syn, etc.) until i do the above. All my other devices connect fine in the meantime! Must be smthng with android....
- check the ip address.
- from device, ping its default gateway
- from device, ping external ip address that is known to response to ping
if all those works but you can't ping www.yahoo.com, it is resolver issue.
if all those including pinging yahoo works, and you still have no access, then the apps has issue or there is firewall.
2 S3 in a 3 days (Internet Isues)
Well, a seven days ago itake a Galaxy S3 from my carrier: Ancel (Uruguay).
IN the First day all fine,but in the night it can´t connect with 3g. In the other day the Wifi STOPs. TheS3 conect with the rooter but can´t navigate.
I change the rooter, resetthe phone (factory Reset) but the thinks not change.
I comeback to my carrierand Ancel take my old phone and give me a new S3 (1 day old).
For 2 days, it go well, butin the final of the second day, No wireless or 3g connect, the same again.
It´s a |Firmware problem, ahardware damage, what suppose I have to do ???
My computer is normal, myold N97 is fine, It has 3G signal and navigate on Wifi and 2G/3G, but my galaxyS3 no …

This technique works for me but only like a temporary solution. Restarting the home router also works for me but again is temporary. This issue I think is with most galaxy s3 devices. I own a galaxy tab 10.1 and it's there in it as well. huge pain to check each time, critical notifications are always missed. Have switched to bluetooth internet sharing from my laptop to avoid disruptions as I just can't trust the wireless.

None of both have commented on my suggestion to use Wireshark on another computer to see what's actually going on.
It's hard to guess the reason since by crystall ball is broken and it's nearly impossible to get magical artifacts in pristine conditions on ebay...
No Way.
But after reset the configurations, today in 3G mode al is fine.
In wifi it shows Conected in calennetwork, after this it show internet not avaliable via selected wlan ap. It can´t navigate.
In my router page , the received packets always change, for more data and the sent packets never change.
In the avanced configuration what is the Network prefix lenght ? In my XT860 and N97 i always select the channel of the router, but in the galaxy a don´t have this option.
But the strange, is that in the 2 galaxy s3 in the first day work im my router, and then after some hours it´s crash and not navigate...
Very bad Samsung.
I´m thincking in change my S3 for a S2 or Lumia.
I´m disapointed for it, because if i change the Firmware version i lost the warranty and i have bad feeling about this isues... Is a hardware fault or a software bug ???

You only lose warranty if you bring it to a store without original Rom. Just use the normal procedure (TriangleAway, Odin, Factoryreset) to get it back to stock and you're good to go. If your device has issues preventing it from booting (so you cannot re-flash original) they can't check the binary counter either :angel:
THancks for the help.
I will going to look for triangleway & Odin in the forum.
With my Motorola XT860 i made a lot of stuff: CWM, Custom Roms... but i dont´t know nothing about the S3.
Just some days reading here in XDA and a will going to know all that kind os Staff.
Sorry for the BAd English...
I'm having this issue. I think it has to be a firmware issue as I don't think I get it if I use CyanogenMod9 or 10 (but I could be wrong)
It really is very annoying and somewhat disappointing.
Hello Again!
I tested my S3 in others routers, and all the router that working without sharedkey (open network) my S3 can conect and acess the internet.
Test your phone with one and post for us here.
OBS: In my TP link TL-WR642G it can´t conect (with and without Shared key) but in the first day yes, i don´t understand it.
I will going to 3 school who has open Internet for all the childrens and this 3 schools my s3 conect and navigate in the Internet.

Anyone with this issue, please try the following:
- Take a Nandroid backup of your phone (on the internal SDcard, restoring from external seems to be broken)
- Flash CM9
- Try Wifi
If it works, please report. if it doesn't, restore the Nandroid backup and report =)
Since CM9 is not based on Samsung-software, that should answer the question about it being an issue in the newer Rom once and for all.
Hello all, I have a Samsung Galaxy S3 GT-I9300 with Stock 4.1.2 unrooted and baseband version I9300DXEMB1. The problem I have is when I try to connect with my home WiFi from my room, it says Authentication Error Occurred. I have to be directly infront of the router then it'll connect and allow me to load webpages.
If I stand in front of the router and connect, It will get connected without any problems but as soon as I return back to my room or any other place that is more than 3 feet away from the router, it wouldnt load any webpages or anything that requires an Internet connection. Then when I toggle WiFi off and on again, the authentication error occurred problem will be back. It's like my phone can only connect and load webpages when it is 1cm in front of the router. Does anyone here have any suggestion on how to help me? I'm pretty sure that it is not my router's problem because my computer and Galaxy S4 in my room can connect just fine and load webpages just fine. I've tried searching the Internet for solutions but have not found anyone with the exact same problem with range/signal strength hence I started this thread.

Suggest wipe phone install stock rom and test .
If it connects to other routers/ wifi its your router a problem .
I had these kinds of problems with two stock ROMs, do not remember the exact versions, but when I upgraded the problems were gone. That was while using the exact same Yank kernel, so it doesn't seem kernel related. It is a very annoying bug though! But upgrading ROM will fix it, I know for a fact that GNA5 doesn't have this bug.
Have you tried using wifi on other places on the same phone?

Rooted the phone and installed Siyah kernel. Problem still persist. Any other possible fixes? Continued my search and found this thread http://forum.xda-developers.com/galaxy-s3/help/galaxy-s3-wont-connect-to-wifi-t1779535 Same problem with what OP is experiencing. (Post #10)

Since I saw that lots of people have the same problem. I like many other, I have done everything said here, and all over the web.
Here is what I did to fix my problem...
1 - Check if you have any special char on the wi-fi SSID like "!,@,',ã,á,~,ç,ã" etc...
and Remove it.
2 - On your router check if you have ip adress ranged configured like: 192.168.1.100 to 192.168.1.150, and change it to the wide range: 192.168.1.1 to 192.168.1.254
This two steps solved my problem after I have tried everything stated here and over the web
I just registered to share this and hope to help someone.
Sorry for my bad english...

The thread also highlighted using static IP to solve the issue.
Plus, you can try to change the router transmission channel to a lower number and see if it works.

Thanks for the reply, hard resetted the phone back to everything stock and tried 2 different stock firmwares but still no luck. I also went to format /data and cache in stock recovery just to make sure but still same problem.

I had these kinds of problems with two stock ROMs, do not remember the exact versions, but when I upgraded the problems were gone. That was while using the exact same Yank kernel, so it doesn't seem kernel related. It is a very annoying bug though! But upgrading ROM will fix it, I know for a fact that GNA5 doesn't have this bug.

Yeah, I'm suffering from OCD and just to make sure the bug doesn't carry over to the next ROM i flash, I formatted my phone through recovery before flashing the .tar firmware in ODIN. And I tried 2 different firmwares and still same thing. Now on MF6 stock 4.1.2 and trying to avoid stock 4.3 because of Knox bootloader.

Have you tried using wifi on other places on the same phone?

I've tried other Unsecured networks around my area. Same problem. Very sure it is not my router problem as my other phone and computer can connect just fine and even getting at least 20mbps speed. This S3 can only connect when I'm physically beside the router.

Thanks for suggestions, I've also tried Static IP and checked my router settings and that it doesnt have those punctuations in the SSID and also the start and end IP is pretty wide from 192.168.1.1 to 192.168.1.253 (I don't think that 1 difference from .254 could make a difference could it?) I'm really starting to believe that It's a hardware issue. I'm probably going to contact a person to diagnose the phone tomorrow. Maybe it could be a malfunction of the WiFi chips in the phone.

If there is authentication error then that means that the phone can detect the wireless network so the hardware seems ok. Did you try to change the router channel? And even try changing the transmission from a/b/g/n to "G only" or "N only".

That's exactly what I thought too. Why can't it connect if it can detect the network? And I've since tried changing channels only for it to return to the same result, authentication error. And my router settings do not have an option to change the radio type. I can't remember exactly where but it might be Android forums or something (read too many different forums over the past few days) and this guy said that maybe it was some power management failure thing. I'm not an expert with hardware and can't provide any explanation or theory. Maybe there's some other component that manages the power to use that'll enable the phone to receive data from the router and that thing malfunctions while the main wifi chip still works that explains why I can still detect wifi networks?
[Edit]I'm also thinking that maybe because this Imaginary power management component inside the phone is malfunctioning/not receiving enough power, that's why when im in a room different from where the router is, i cannot connect because the phone isn't receiving enough power to validate the data from the radio waves and also because when Im standing beside the router then can load webpages just fine because the Signal strength is high and probably the radio waves from the router is emitting high energy so the power management component doesn't require as much energy to receive data compared to when Im in my room. Something like the router shouting and your phone needs a certain amount of energy to hear the voice from the room otherwise you cant but if you're standing beside it you can hear it no matter what. (This is just my theory and what Im thinking the problem is. It is not an explanation but just my opinion. This information could be totally wrong for all I know.)

@Hazerm, can you try WPS setup if your router supports it?
On your phone: Settings > WiFi > Menu > WPS
Rebooting the router is also recommended. Maybe you can also try changing the security on the router to WPA/WPA2

Yep, WPS is supported and enabled on my router. Use it cause I was too lazy to retype my password everytime i flashed a firmware on the phone haha. And same thing. when I try to connect using WPS, the phone (in my room or any location 10cm or more away from router) doesnt react even after pushing the button on the router. But if I were to stand beside the router, WPS works without any problems.

Ok try using airplane mode when you are standing at a distance and check if the wireless connection continues.

No improvement, unfortunately The progress bar just crawls to the end and the phone just says WPS failed. This was approximately 1 meter away from the router, I have to be less than 1 metre from the router to get a connection. Btw, router was rebooted several times and Security has always been WPA/WPA2-PSK, not very interested in changing the security to other types like WEP. Just not very trustable

I can understand that this is very frustrating for you. Believe me, I've had issues with phones and wifi
Ok, so I found 2 short threads that you could read:
Link 1
Link 2
Summary:
- try the steps in Link 1
- Change phone frequency from 2.4ghz to 5GHz (had this option in Omega ROM 4.3-based)
- 2 users report that the issue is fixed in CM9 (or even other CM roms)
- Might be a mainboard issue after all.
PS: Surprisingly, some of the people reporting the issue have used Omega rom in the past and faced the issues since then. (I didn't have any issues though so I cant blame the rom)

Unfortunately I'm not the original owner of this S3 so I can't be sure if the previous owner flashed any custom ROMs.

Don't worry about Knox, it is not present in 4.3, so you can just flash GNA5 and be done with it! I do recommend Nova or Apex launcher though, way smoother!
For all the other people here, this is a known bug with certain routers that are not 100% compliant with the WiFi standard and therefor do not confirm the handshake. I have had these problems with certain ROMs as well (cannot exactly remember which ones) and after flashing another ROM (at the moment I am on GNA5) Samsung fixed it, while it is not even their issue, the issue/bug lies within the routers that pose problems.

Really? Because with the Galaxy S4, late 4.2.2 firmwares and all 4.3 and above firmwares had new Knox bootloaders which means no turning back to old 4.2.2 ROMs and also the Knox 0x1 flag which to my knowledge is not resettable at the time of this writing.
