Wifi disconnection (Multiple WIFI) - Galaxy S III Q&A, Help & Troubleshooting

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?

Wi-Fi is not working with secure Network

Hello

Hmm are you typing with auto-correction on?
If you mean WPA2-PSK (WPA2 with password), then I can confirm that this works.
I have a similar issue with my 'O2' router (rebranded Thompson 585 V7) and have WPA+WPA2 (WPA-PSK Encryption) setup.
All devices in my home (laptops & Ipod Touch's) have no problems, but my new Hero continually fails to get an IP address. Seems to connect OK but then continualy cycles therough 'Obtaining address'... 'failed'.... 'Obtaining address'!
It did successfully connect once for about 20 mins, but after a phone off/on, has gone back to failing.
I'll experiment further, but may have to return the device

Glenn

I'm still waiting for my hero, so I might be wrong. But according to the manual, the hero can only handle WEP encryption on WiFi. WPA/WPA2 are not supported. I think, for the hero to work on WiFi, you must change the encryption on your router either to WEP or to unsecure.

I tried WPA-PSK and WPA2-PSK with my Hero and they definitely work. Sorry, mate ;-)
If the OP wants some help he needs to post some useful data about his setup and what works and what does not work.
I can confirm it works for wpa2-psk and PEAPv0/EAP-MSCHAPv2
Wi-FI is not working with secure network
Hi
I had same problem with BT Home Hub2 all i did was a soft rest and it worked and had no more problems so try soft resetting you routor
Well, as posted earlier, despite several hours of every possible combination of settings and factory resets, I can't get my Hero to use my WiFi (WPA+WPA2, WPA-PSK Encryption).
I have seven other devices that have no problems at all (I configured them all), so I'm assuming it's an issue with the Hero. Therefore, it's going back to it's supplier.

Yep it may well be a faulty one if its from a store try get them to test it if they can if not the get the new one home and try again you might also wont to try it on someone else wifi see if it works on theres. Also it might be that the amount of device conected to it may be causing a problem on first time setup, you could try it on its own then let other device connect to route worth a try
You should bear in mind that sometimes certain devices just don't get on. Someone posted here earlier with a similar issue, and they found changing their router from the Orange supplied box to another one "fixed" their issue.

Dave
I found problems connecting my Hero to our Belkin N1 Vision ADSL Modem/Router using WPA2-Personal.
In the end it turned out that re-enabling the option to broadcast the SSID solved the problem. For some reason creating a connection manually to a network which does not brodcast caused the issue for me.

Ian

So there is a generic advice, run your wifi in a standard-compliant mode. Broadcast SSID and turn off all the vendor-specific "turbo mode" and "extra-long/short" packets crap.
Problem with wpa2 enterprise
I am not able to connect to wifi at work.
We use wpa2-enterprise with PEAPv0/EAP-MSCHAPv2 and broadcast SSID.
Hero detects wifi network with incorrect security. It displays: "(network SSID) secured with WEP". When I tap on it it asks for WEP hex key...
I tried to add wpa2-enterprise network manually. It says "not in the range" and keeps offering me the above one with wrong security...
any ideas?

[Q] wifi connected but can not connect

Hey I'm new to android, just got a vibrant last week. Decided to unlock it as I travel a lot. The unlock worked, but now I'm having issues with my wifi. I can connect to a wireless network but I cant load pages. The wireless signal is strong and I tried with different routers, but still no luck. Looked through the forum and googled it but couldn't find a solution. If some one could please help with this, it would be much appreciated
try clearing your current wifi settings including remembered connections, passwords, and everything else...then re-scan for networks all over again, that's all I can think of for now
By that you mean just gong into settings->wireless and networks->wifi settings and then just forget the net work, rescan, and rejoin the network? If so, I did that but am still getting the same result. If you can think of anything else or if I didnt do what you suggested correctly please let me know. Thanks

yeah, thats what I meant :/....hmmm...sounds like your connection is working, can you download stuff from the market or is it just the browser? cause I unlocked mine too and wifi works fine
No I cant download anything from the market. I cant do anything that requires an internet connection, but it does show that I am connected to a network.

I sure hope so, thanks for your help
Have you been able to try another network? My first thought was it was in Ad-Hoc mode but I could be wrong. If nothing else restore to stock firmware and then try a different unlock.
Happened to me too. It would show the wifi icon on the notification bar but wouldn't load pages. I'd go to the settings and it'd say can't turn off wifi or can't turn on wifi. And when it was "on" I'd say connecting to modem then it'd just stop. When I was using the browser on wifi it would load a page even when I had full bars. I had to turn it off then back on to load another page. Is this similar to the problem your having?

I hope this doesn't sound stupid but yesterday I uninstalled Advanced Task Manager and poof my wifi started working again. The phone also seems to suffer from less occasional lag without it installed, but that's another story for another thread. Prior to this I had to manually turn my wifi connection off and on, but even that didn't always work. Since the uninstall I have not my wifi connection once. I am currently using the stock rom, rooted with minor adjustments here and there.
hi guys, i also have this problem.
i will be taking the phone in to the tmobile store on thursday.
it shows that i am connected via wifi; however, anything that requires an internet connection does not load.
very frustrating, since just yesterday i used the samsung kies software to tether a network for my laptop. i was testing the capability of the vibrant to act as a modem, and it worked just fine.
any help would be appreciated!
thank you
Charlie
connected but not connected
I also have this problem.
In my Vibrant shows that i connected, but i can not load pages. Someone
found any solution to this problem?
Hi all,
This is happening to me too. Rebooting seems to get Wifi working correctly again. But the problem comes back eventually.
Maybe a bug in the latest JI6 update?

Try connecting using ; WPS. There's a button on your router. from the point of pressing you have two minutes to connect. Try it and lemme know.

Samsung Galaxy S3 connected to WiFi but no internet connectivity

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
Tried restarting your rooter?

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 …
I ´m very confused with this situation ... Twophones in a 3 days …
Just joined to give u a suggestion
TRY
call *#0011# (Takes phone into service menu)
press menu key and select wifi
Disable wifi powersaving mode
You may need to repeat this upon phone restarts but it may well sort out your problem

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.

not working for me
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.
Thancks for the support, if anybody change the firmware and the phone come normal again, please comeback here and post for us.
I have this problem too.. since omega. Strange...'
Sent from my GT-I9300 using xda premium
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.

WIFI connection gets weak when S3 trys to connect

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.

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..

Hi, Thanks for the response.
Yes I did everything through recovery. I havent rooted my device. So I cleared cache and did factory reset through recovery.
