WIFI connection gets weak when S3 trys to connect - Galaxy S III Q&A, Help & Troubleshooting

Hi
I have a very weird problem with Galaxy S3.
The problem is that suddenly out of the blue, the phone no longer connected to my home wifi, which it had no problems connecting to it.
the signal is extremely weak, and only connects to it when you sit next to the router.
When you forget the connection, the bars go up and connection looks very strong. as soon as you start connecting to it, it drops to the way it was, and not getting connected.
All other stuff I have (laptop and other phones) work perfectly, so not a router thing
I have rooted and updated to the latest ROM, but still same problem.
Any help would be appreciated.

is this happening with all wifi networks or just ur home network. If only on home network then try turning off your router and then restart it after some time to see if thats causing the problem.
also have u installed any updates/roms recently?

Well, I have not tried any other wifi, but I have another phone and laptop that work perfectly with the same router.
I also restarted the router, but nothing's happened.
I installed another ROM, but this time it keeps asking for password as it says it is incorrect. but as soon as I stand next to the Router, it hooks up to it with same supposedly incorrect password.
Regards

Had similar problem and I think a few people experienced this where suddenly the phone stops playing nicely with WPA2 security, so that's worth looking into

Try running router for a few days with no security see what happens .

Nothing worked!!!
Dear all,
I have tried every solution there is, tried so many routers , work, hotels, cafes ..nothing same problem keeps coming up - authentication error occurred.
when you get close enough to router it works automatically.
I have since replaced firmware many times, have replaced the antenna, but nothing ...same problem.
Any help please, I am out of ideas!!!
The only idea for me is dump it and buy an iphone!

I am facing the exact same problem with my S3.
I have all security/no security. Is there any solution?????
i can also try to repair my phone, provided someone can explain what to repair.
Looking for a response.

Same problem
Hi,
I have the exact problem.
Wifi works when phone close to router (2-3 metres). When away it still shows connected but wont have internet access.
If I try to connect little away from router with full wifi signal, it says "Saved Secured" or Authentication error.
Tried flashing different stock roms but still same problem. Tried resetting router. Tried changing router channel and disabling security. But still same.
Anyone fixed this issue?

Have you both tried a complete clean install? And by that I mean wiping /system /data /preload cache and delvik.

Yes, i have even tried other roms too..

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.
Take a look in the Modem Collection thread in the Android development section.

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...

Galaxy S II Wifi Problem (Need to Restart It to properly work)

Hi guys, in this days i have noticed a problem with my gsII.
Sometimes I have the gsII connected to my router but internet connection doesn't work.
I'll try to explain better what i mean... I start wifi on my gsII and use internet connection without problem. Then I set the phone in standby mode leaving wifi on. When after a while i want to use internet connection, it doesn't work. The telephone is still connected to my router but i can't use internet on the phone.
The only way to make internet connection work is to disable wifi e then reactivate it.
This is really frustrating....
I've got the telephone from three months but only now I'm noticing this problem because first I used to disable the wifi and activate it only when i need it.
Am I the only to have this problem? Is there a solution?
Thanks to everyone in advance... any help would be appreciated
A video is more than thousands of words, so this is an "example video" of the bug:
http://www.youtube.com/watch?v=4um-AqLk1jw
Test it with a different router, i.e. Cisco E4200.
It would a good idea but i have to buy a new router or go to some friend's house for 2-3 hours. I'll keep this idea in my mind thanks

I do not know what " standby mode" is? I have the same phone and have no problems with wifi. The phone goes to sleep when I do not use it and awakes when I use it.
It seems that your phones wifi is sleeping and not waking up. I always turn it off when not using it anyway. Not the full answer but it works for me.

I believe I know and had the problem you describe.
For me the Wifi would work perfectly at first and then after the phone had been left for a while I would try to use it and get 'no connection' type errors. Sometimes it would even stop working even if I just waited too long with the phone still on in my hand.
I found that if I either disabled router wifi security or set it to WEP the problem disappeared. The issue occurred on 2.3.3. My router is a DLink one fyi. I have yet to test 2.3.4 which came out yesterday in Sweden. Ill let u know.

If you turn wifi off when you don't use it, you'll never see this bug. Try to leave wifi on for some hours if you want to understand if also your gsII has this bug.

I tried changing the channel also. I have heard others getting this to work. Didn't work for me. You can use Wifi Analyser app on phone to find a clear channel and see how u go changing your router perhaps?
I tried re flashing also using factory restore. No fix for me.
Also noticed that u can sometimes get phone to work by toggling Network Data on/off. Not really fun either.
The wifi channels and security settings I am talking about are settings in the router not the phone. What wifi security are you using in your router?
Sent from my GT-I9100 using XDA App
I am not a believer the router is at fault in any case. I would entertain an incompatibility but nothing more.
Original router and security settings work fine for...wait for it...an iphone 3gs and a Motorola Defy (yes the phone which seems to have issues with doing everything else!)
Either way an incompatibility is not acceptable either if that's what it is

I know this, and in fact i have to switch off and on wifi connection when this happens.
Now i'm trying to use channel 5 with the router ( but yesterday I've tested channel 6 and 13 without any result)
I hate this bug because beacause it happens only when he wants! I'm quite sure that assistance wouldn't solve the problem. A friend of mine has changed three gsII and said that every gsII that he has changed had this bug!
Ps: Another question.... How often do you have this bug?
Once a week? Once a day? Three times a day?

i have the same problem reported in the 1st post.
i have been turning wifi off and then on again for a quick fix until now but i think the solution might be to drop the security on the router from WPA to WEP. Haven't tried it yet tho, because it doesn't bother me that much.
I had an ipad previously (before i had the SGS2) and it had exactly the same behaviour. I looked up the problem then and found a FAQ from the ISP that mentioned a compatibility problem between ipad and that router, so their suggestion was to set the router to WEP only.

Easily more than 3 times a day but then I use the phone a lot.
Problem had never occurred when I used only 3G. That was my workaround when I got fed up with it before I dropped the wifi security.

For me it happens always after the phone comes back from stand by with wifi on.
steps to reproduce:
1-turn wifi on, and check it's connected and working
2-press power button to turn off screen
3-turn phone back on, try to access a new web page, it doesn't work
I noticed that while it's in stand by i will still receive email notifications so it probably only looses the connection when i turn it on again.
Also, if there was some program working (say, a download) when i went into standby it will probably still be transferring when it comes out of stand by, it's just the new connections that fail.

Wifi seeing router - not internet but on data works perfectly - help

Hi All
Having a spot of bother tonight
Randomly my SG2 could not access the internet through my router.
It sees my router, no problem there. I can switch off wifi and get online with my data but not through wifi.
I had been using it all day but it just randomly stopped tonight and my router is working perfectly as my laptop and other phone is connected.
I have restored 3 different Roms which were up to two weeks old in some cases. Also flashed 3 kernels and 3-4 modems
On ICS Stock rooted LP7 with CF root LP7 kernel
Not sure what else to try so any help would be appreciated
I have searched and tried everything I can so if you can help, thank you.

I tried it, but unfortunately it didnt work for me but I appreciate your help.
after flashing it, I couldnt even turn on wifi at the toggles or menu so I am doing a restore now and hopefully it will work.
I am not sure if doing a complete restore to stock firmware again will work.
Really dont know how this wifi issue so randomly appeared
Was your phone getting a DHCP address from the router or not ? on ICS, that happens when you get the popup message "Connected to XXXX".

Hi Vaxxi
If I dont understand what you are asking correctly, sorry.
the phone is receiving an I.P., gateway, dns, etc. each time I log on.
I can see that wifi connectivity is active but nothing is working despite clearing caches, doing restores, etc.
the problem started randomly
Yes, I was asking if it gets an IP through DHCP. Sometimes it gets stuck and you have to remove a file manually in order to refresh the IP address, but your problem seems to be somewhere else. Can you ping your phone from the router after it gets an IP address ?

I cant get near my router tonight unfortunately
I can 'see' it through 'Fing' app but if I try to use speedtest.net app to see if I have data, I get nothing.
I think I will try another stock flash again with LP7 stock, but I doubt it will work.
____________________________________________________________________________________________________________
Note: Fixed.
I did all the above to no avail.
Ended up reflashing the router firmware, not sure if this directly helped but upon reboot, my phone connected as usual but now had internet access again.
Strange as prior to flashing the firmware everything except my phone could avail of net access.
Thanks to each of you that helped.
im having the exact same issue. I have reflashed router firmware also but still nothing. Wifi symbol is there but not blue (cm9) data works perfect. Im also starting to wonder if its my router.
I have tried wiping all settings etc. Um currently downloading latest nightly so hopefully that does the trick!!

[Q] Wi-Fi Problem

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.

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

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.

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

Meanwhile, I will try to search for another solution and post it here if i can find anything.

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.

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.

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.

Wifi disconnection (Multiple WIFI)

Hello everyone,
Last week, suddenly i could not connect to my Home Wifi. And now that I am at the office a tryed again. No luck.
When I hit the SSID in my netwrok list it seems to connect but within a seconde it says: savec, secured. And I un-disable the screen so i can hit the network name again.
I just performed a reset, probleem is sill here. Is this a hardware issue? Is there some logging somewhere?
Kind regards,

If you are on stock rom, you can try entering service mode by dialling *#0011# and disabling Wireless Power Saving mode.
There was another fix involving etc/wifi folder on the device,but I cant find the thread atm.

I changed it but it has no influence. With wich program can I record my screen in order to post it here?
It actualy disconnects only 1 second after trying to connect.

I'm trying to find the right thread which had this info.
You can also make sure that the router doesn't have too many connected devices, sometimes that is also a problem.
BUT if it connects and then drops (It says "Connected" then "Saved, Secured") then that could also mean hardware issue. Because there is no problem connecting but your phone can not maintain connectivity.

I think it's an hardware issue. It stops suddenly after 2 years of good service. Do you know if it's something that can be replaced? Or is is on the mainboard? And shoudl i buy a new one?
