S3 wifi not working
(repost this to this section, adviced from xda assist)
I just purchased second-handed Samsung Galaxy SIII GT-I9300 (international ver) to replace my old Samsung Galaxy Mini (GT-S5770). I purchased this cuz the price tag on one of local stores is just too tempting me to buy one, plus, giving me free true leather phone case! (though my target was Acer Liquid Z410, but not available on local stores and i dont know how to buy online as well)
The phone conditions, well, do have some minor scratches at the sides but the previous owner was middle-age man, and im not so picky with that detail.
The phone is great, well, except, the WiFi isnt in good condition in normal uses. (means, i can still uses them. details in below)
The S3 properties,
Android 4.3
International ver, GT-I9300
16 GB ver (which i found out some cases with unbootable S3, with 16GB ver only)
unroot
all related to network setting (includes mobile network, Bluetooth network, WiFi) is in default
The problem is, the WiFi.
The phone does detects WiFi hotspots or access points from far (in fact, it can detect my neighbour's home wifi even though is quite far, well, maybe around 20-30m, well, the signal was weak though).
SInce my home wifi is hidden, i pre-set the wifi. but, it wont even connect or even detect my wifi. My Internet TV with WiFI Direct do detected though (no internet connection since it wont host internet to devices who connect to the TV)
But, when i place my S3 like below 700cm range, my S3 detects my wifi and connects like normal devices. But when it get like further than 1m, the WiFi does not receives any data at all and after a while, the WiFi disconnected.
After i bought this phone, i hard factory reset my S3 (before reset, i didnt test WiFi and also from my uncle's advice cuz my phone seems a bit slow, well, he used to have S3). I didnt had a chance to test WiFi until i got home and tried to connect my WiFi.
I've tried many method i found online, (again, the WiFi only works if i put my S3 side by side with the access point/s)
Reboot router (I always reboot them cuz the router sometimes bugging) = not working.
Forget the network in S3 and preset. = not working
Tied with static IP address (connecting to my hidden network)(with google DNS) = not working
Enabled unhidden, open wifi profile on my router, try connect. = not working)
Connect to my TV's WIFi with WPA security = not working (tried to connect but just fails)
Tried *#0011#, Wifi, turn off power saving = not working
Things i havent tried,
reset again the S3
revert to factory firmware (actually, i tried but Kies 3 just wont work at all... it said that the device cannto be initiated or similar... so, the S3 didnt do anything)
using Odin to revert to stock factory rom
using Odin to update to unofficial kitkat rom
before im going to use Odin, which i dont ever done before, do you think that reset this phone to factory setting will fix this problem?
Try changing your router's channel.

if you mean router channel, the N radio, G radio and B radio,
sorry,
mine only supports G. (or maybe B and G. but for sure, no N)(dont forget that i did tried with my tv as well, since my tv has wifi direct but also be connected with usual wpa security. by the way, im pretty sure the tv radio channel supports b, g and n, and usually, they uses N channel for devices that supports N channel).
if thats not the case, then what do you mean?

This really really pi##es me off, as where I live I get 1x data, & usually use my home wireless (wifi).
Recieved the pro, and activated it. It seems disabled by being activated by alltel. I even stumped the blackberry adept person at the local store enough that they switched out the phone, I walked to next door (motel) used the free wireless (to prove the wireless would even function) then let him activate it and headed home (30+ miles into the wilderness). got home and again I cant get Crap wifi to work.
Home is wireless b, it connects, can be seen on the 'simple' 2 wire wireless appliance but the PRO, will not see or try to send data through it. turned off security and everything on the wireless for testing. I can check, but I know the pass for the motel, and I could try again, but am definitely sure that this AINT the issue--> again the phone wouldnt connect at the motel (least not the pre exchanged one) with me or the rep at Altel either, while it was activated and on alltel.
who to call? Any help out there?
my 6800 will still wifi, at anyplace there is a signal and that I know the passcodes or is open.
yes I asked this, at alltel-howard forums, but would think you guys here know more (on second thought, when I remembered about all the stuff you do here, I know I probably should've posted here 1st, but Im kinda mad at the moment!)
Pretty adept at computers, I do IS as my real job, anything I can do to help trouble shoot? yeah the 6800 has been flashed & I even noobed around with cooking a few time. appreciate any help you guys
i Have a touch pro and a touch diamond, both under 2 weeks old and the wifi works fine with both of them, maybe you should try a custom rom and see if they changes anything. but there is no reason it shouldnt work with the stock rom

goony,
Is it an Alltel? are you positive that wifi is working, not the "data" connection with alltel towers (cell call)? My proof is that if I goto my basment, I have no cell service so not any data connction, ONLY WIFI (that is where my wireless router is. that is when I found out the 1st time. Everything else looks right, on the phone it says it is connected, on the router I can see it on the connected devices list.
I have my issue that I believe, that it is some setting that Alltel is setting... like I said the phone would connect via wifi until the phone activated. When I activated (full unlimited data package is on this phone) the phone fully rebooted on its own, 3 times as if getting updated via data plan. Im not talking about the 1st time turn on customizations, those were done before I tested the wifi at the motel lobby... For instance, the volume control buttons - the display app were obviously modified, I am not positive what else was.
I'd LOVE to try custom rom, if I wasnt right in the period of time I can get my money back, or not. after that I will...
yes they are alltel, and to test the wifi i just connected it to my router and then turned of my alltel data and it stayed connected so i am positive the wifi works. you can still use a custom rom under your return period, if you want to return just relock it.
I wanted to double check myself sting to make sure i was realy getting wifi, so i connected and went to speedtest.net and did a speed test and sure enough it showed my isp as roadrunner(my home provider). Have you had this problem with multiple phones? are you checking the internet option when it connects? and do you have it diconnected from the pc? my wifi wont work on my diamond hooked to a pc.
Has nothing to do with alltel. Maybe with the rom or the phone. Now I hope you're not waiting for a pop up to show itself on the main screen asking if you want to connect because you could wait forever. Go to comm manager enable wifi/ go to start->settings->connections->wifi and make sure options are set to "all available." If you can even see wireless networks on the list, the wifi is functioning correctly and there is a router settings conflict. If you don't see networks on that list in wifi, then there is a rom/hardware problem.

Hey thanks!
But, it is the Stock shipped rom, I have my HTC 6800 right next to this one, connected and surfing the web, both show up when in the home WIFI router config as connected, yet the pro sends NO DATA to ie or opera, (cant locate any webpages) or any app that uses internet/data.Unless there is something I need to do with PRO that I never had to do with the 6800 (mogul) that I just flashed back to stock shipped rom, ready to sell on ebay...
what I dont know is, well, most of the people wifi to tether a laptop or something, I dont! Sure that will be neat in the future, but RIGHT NOW, Just I use WIFI when I am at home and dont even have signal or evdo near me... (remote locations that I live, the tower coverage sucks out here in ks...) Got to fix this soon, or this Beyotch is going back to alltel.
Another thing, this bad boy pulled this crap, as soon as alltel activated the device (so I could use it as my phone!) when it was NOT activated, the wifi worked (proven at the motel next door to the Alltel store I exchanged this phone). BTW, I was able to test it on the 1st phone shipped to me, while it was activated, it pulled the same thing, when he unactivated the phone, we could almost pickup the wifi from the motel next door (distance was the only issue I think now looking back) but seemed like a chip problem.
Where I got screwed was we believed the wifi to be bad on the 1st phone. So he got out a new phone, and before we activated it, I went and tested the wifi, it worked on the 2nd phone. I thought wall was fine, it worked. then I had him activate it, assuming that proved I will be able to use the wifi. So I leave the store thinking OK wifi works. I get home, and again unable to use my home networking wifi to open web or apps. unacceptable. Yet the 6800 does and still works flawlessly (as long as you slide the wifi sider on side to on {inside joke}).
follw me better now?
What brand router do you have? How many devices are wireless? And it connects to other locations but are you sending and recieving data? Try this link http://www.wmwifirouter.com/trial/ and install on 6800 if you are not normally around hotspots. This will test the t-pro's ability to send and recieve information via wifi. Now it is sounding like an IP address conflict.

Sweeny, Im in the houshold router (made by 2wire) I can see it (the Pro as well as the 6800) each get an ip. (I work In IT, so I know what you are talking about in ip conflicts, all that.) I have even set the router to manually setup IPs now, then set the ip inside the Pro, as well as the default gateway, dns all that.) I'm telling ya, it is more like it doesnt know the DNS or the gateway (just like I disable internet surfing on the computers at work that I still must use networking)
I copied the DNS and everything from a working laptop (ipconfig -all) on a wireless laptop today, and still as if it was disabled.
This weekend i will test the dang thing tethering with my notebook i'll bring home from work (use the pro as the internet access). if it wont tether either, then I think allHell is doing something. Again if the device is DE-Activated I will wifi... {I'll bet you $$}. I might call alltel, tomarrow night, and try that. I'll have them inactivate it and if it suddenly works, then the question is, what do I do with alltel? they dont have the right to disable hotspot usage do they?
I feel I feel the presence of VERIZON already in Alltel, Luke is turning to the dark side. NOOOOOOOOOOOOOOOOOOOOOOOOO!
You all thought I was off my crock...
http://www.htcwiki.com/thread/2073117/Touch+Pro+WiFi?t=anon lots of folks posting same problems it looks like.
Need that group of people who can create a kitchen, and hcak tomtoms, to help us with this PLEASE!
No I don't, think you're off your crock I just know how frustrating problems like this can be. Here is what I suggest you do. And if this doesn't work exchange the phone or try a different router. I know what you're thinking....not the router. Truth is might be. Its just like wireless adapters in wii's and ps3's they simply will not work with a handfull of routers even though not clearly documented.
Anyway, change router to static Ip's, safer anyway.
Specifiy gateway, primary and secondary dns, and limit your ip's within 100 available obtainables. Use a 64 bit wep encryption. Change the channel of your router's broadcast to 1 or 11. Use only simple gateway ip range, not pure server. If you need me to provide you with example settings then pm me because I do not want to broadcast them via forum
Good luck.
Dont take this the wrong way....but are you positive that you are disabling the DATA Connection in Comm Manager?
I have had the alltel touch pro since the second they hit the store. I have used 3 of them since and they all work perfectly on wifi. I primarily use wifi and use diamond tweak to activate the wifi standby so wifi stays connected in standby like data does by default and use modaco nodata to disable data as I live in a house that gets a very lowsignal from the tower and eats my battery superfast if I use data. I have a router in the house and one in my office detached from my home and when I had my mogul it often would not switch between routers successfully requiring me to manually connect more often than not. All the Touch Pros connect superfast and switch automatically. I am running mightyrom 4.12 and telus radio which is light years better than stock with signal, speed and batterylife, but even when I was on stock for about 3 months there were absolutely no wifi issues.

Not sure which of us you are asking this queston of...
Thanks, for the help so far...
I was having the same issue (Alltel and all).
I found this post in the MS forums:
http://social.microsoft.com/Forums/en-US/windowsmobile/thread/561f18a8-5f64-4359-957e-adb003229f1d
Essentially, it says to "Navigate to START/SETTINGS/Connections Tab/Connections icon/Advanced Tab
Press Select Networks Button
At the top it says "Programs that automatically connect to the Internet should connect using:"
You want to press on the drop down and choose My Work Network"
You need to tell the system that the Work Network connects to the internet as well. While this doesn't seem like the ideal solution (there should be a faster way to switch it, or it should do it automatically depending on location), it did work for me. I'm sure there's a much more sleek solution out there, though.
Btw... I hope I'm posting this correctly. I'm more a reader than a poster.
Ooop... one more thing. Its non-sleekatude rests with the fact that when you want to switch between wifi and your data plan, you have to go through the whole process, and switch the active network from My Work Network to Alltell Wireless. This is where I was hoping for a better solution. As I say, it does work, but it seems like it should involve less hassle.
Might add this to the WIKI, I dunno but there could be a few more thousand users out there on ATT or SWB using the modem/routers that they shipped when you got DSL more than a year ago...
Everyone that has the older 2 wire brand, wifi modem/router that came with SBC (now ATT). Wierd I know. But Mine has just been replaced by the newer version of that modem/router. and I will be dammed, it works. but the phone wont work with the older ones. Mine was the 2WIRE 1000hw model. they are shipping new models, and finally the phone will work with the wifi on that new router.
Thought it might be nice to know...
alltel model uses wifi just fine
My TP from alltel works just fine with wi-fi all i ever do is turn it on and then select which connection i want to make ...really quite nice...maybe you need to exchange yours...
On further testing of my own setup, I'm thinking my issue was the router. I had done several fixes all at once, and cited the wrong fix as the working one. I happened to reset my router at the same time I did the above suggested fix.
I thought it had to be the device, as my HTC Apache never had an issue with the router, but after resetting the router, and going back to the original settings on the TP, I'm having no problems connecting to the network. I wish I could pinpoint the exact conflict between the two, but now that I have it working, I'm not messing with it.
My suggestion is to back up your router settings, reset the router, and see what happens. Or test your wifi on someone else's network.
Isolating a network conflict can be one of the least fun things to do, but from everything I've seen here and in other forums (and my experience with it) I'm going to say that's the issue, and not the TP alone.
I don't think it likes your router being wireless B, you should try it on a wireless G router before Ebaying it.
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 …
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.
Hi,
I had no problems so far, but my Router broke and I got a new one. From this day one my Samsung Galaxy S3 phone is having this annoying wlan disconnects.
I have lots of wireless devices (laptop, tablet, 3ds, lots of htc phones etc, kindle) non of this has issues with my new router.
But somehow my S3 keeps losing the connection. This usually happens after I left the building and come back.
I look for many solution but couldnt find one working.
I tried the always on during stand by (it was anyway always on)
I tried to change the 2,4 brandwith but somehow this option is not availibly on my phone
I tried the *#0011# something number (I forgot) to change the wlan sleep time, but this option is not availible on my phone.
My router is using a dhtc ip distrupition also is using the b g n, which seems to work with any other device. I heard i should switch to only b g. But this lower the speed by 3, i dont want to do this. If this is the problem is there no fix for the samsung phone?
Thanks
ps after reconnecting the internet works without problem is the disconnect during standby which is annoying
Try a factory reset .

I did now a factory reset, it didnt work. I still have the same wlan problem. And now I have to press like 3x connect until it connects to the wlan network...
The problem is solved with the patch released in January.
This big updated fixed all problems.
I've noticed that whenever my wifi is on, and also the "always scanning" option is on - my phone suddenly connects to a network called "0x".
It doesn't really work - there is no internet. It happened in different places, inside and outside my country.
Does anybody know what it is?
UP
Old post, but happened something similar to me. Sometimes when I have just connected to my wifi network and I look on the menu it displays "0x". Your phone was probably connected to a public wifi or just bugged.
Still doesn't explain it though
In my understanding, the 0x is a garbage SSID that indicates that WIFI configuration data is obsolete.
Ite wonderful if u ask me ☺?
I booked a hotel room and when i arrived thr...my device got connected to Ox wifi and it has over 2Mbps speed...so i was curious about this Ox wifi hotspot so i searched on google and i found ur post and now i am more curios about it. What the hell is going on lol...
.
In my opinion it may have some connection with rooted devices bcz my device is rooted and i have samsung s8 as well and it neither finds this Ox wifi nor gets automatically connected☺:fingers-crossed:
Edit: As far as I see, it might a bug of Android with special cases of bad connection. Like it connects somehow, but can't get SSID. Turning on "avoid poor wifi" seems to fix it.
Same here. I've saved two wifi connections: one is my home network, other one is a network of free wifi transmiters offered by my ISP (UPC Wi-Free). My phone is Motorola Moto G with Android 5.1. It's not rooted and never has been.
I live around elder people and there were no strangers so I doubt some grandma suddenly established malicious network. Probably a bug, but the bug of what? Android? Some external software? I use Nova Launcher and Wigle Wi-fi. Do you?
0x seems to be prefix of hexadecimal numbers, but it doesn't make much sense. It wouldn't mean "hexadecimal zero" (which would be 0x0), but "hexadecimal nothing".

I've seen it too, then the actual SSID of my home network appears. Maybe Android shows '0x' when it doesn't know the name of the network it's on.
Tab S3 worked well on 7.x. Lost wifi completely address 8.0 update. Tried all the recommended forget connection, reset network, full wipe after ota . When all that failed I flashed the full 8.0 with Odin. Still had no wifi. Repeated all those reset steps again with no joy.
Strange part is the same situation occurred with my LG V30. Worked well on 7.x, no more wifi after ota to 8.0. Repeated the resets and full flash series again but still won't connect.
My Razer Phone and One Plus 6 phones connected to the same wifi out of the box (with 8.0?), ota'd to 8.1 and have been solid since.
Am I stuck waiting for Tab 3 / V30 flashable (stock) files to 8.1?
You can download some network tools from the play store. See if they help you pinpoint what is going on. You don't happen to have MAC address filtering turned on the router? Though doubt your MAC address would change but I did read an article where Apple changed the MAC Address in their iPhones after it was discovered the government tracked people by MAC address. So it is possible it changed. See if you can hit a public WiFi (library, coffee shop, etc) and get it to connect there? Or a neighbor's network?

@aspexil
Just set the hotspot on one of the working devices and see if you can connect to it.
Is the wifi actually enabled?
I had the same problem happened to my Tab S3 a few days ago after I upgraded to Oreo (8.0) I could connect to WIFI but it says I have no internet connection. I have tried different routers and at different places and still the same problem. Strangely, I can connect to internet from time to time (intermittently) despite my Tab S3 giving an exclamation mark on the WIFI signal and warned me I have no internet access. I have tried resetting network, factory reset no less than 5 times, and also tried connecting at different places. I have read somewhere that by changing the time on the unit fixed the problem for quite some people, but didn't work for me. I did not root my tablet, so now I'm stuck looking for solutions.
update 2018.12.05: there was a new patch out (Oct. 2018), so I updated my S3 and now it still doesn't see internet even after connecting to WIFI. I tried resetting and now I can't even pass the Agree to Terms & Conditions part as it still says I have no internet. Before the patch update I could at least access internet even though tab S3 thinks I am not connected to internet. Guess I have to try to root it or throw away the tablet.

No have not rooted. All stock now. If all else fails, I guess I will have to try to root and flash ROM and see if my WIFI can come alive again.
