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.

Are you sure the password is correct? Sounds stupid but well...

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...'

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.
Hey Guys.
Recently my WiFi symbol in the notification tray turned grey and didn't go blue again.
I've noticed that when the symbol is GREY, I'm not able to access Facebook (through it's main App),it shows "Updating" only.
But to my surprise, the net works fine in the Browser ( inbuilt browser)
After analyzing the problem, I found that whenever I turned my Laptop on, the WiFi signal goes Grey..
And when I switch it off, it turns blue.
On further investigation, I came to know that both the devices (laptop and phone) have different IP's
Plus, another android device works well with the laptop being on.
I'm using Xolo Q600
Android 4.2.1
*no root, nothing...I'm amateur*
WiFi Router NetGear N150
Any help will be thankful.
Lakshya.
Have you tried reseting your modem? or forgetting the wifi net with both devices and set up the connection again?
Hope this helps

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?

In router set a google DNS
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?

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.
I have Samsung Note 3 Neo(SM N750) running Lollipop 5.1.1, since 3 months I'm observing that my phone is not connecting to any wifi network at my office. I have an personal alcatel hotspot to which it connects at home, but it is not connecting to the same device/network at my office location. My colleagues are able to access without issues, infact my phone is not connecting to any of the available networks at this location. Sometimes it connects for few seconds and shows 'Saved, secured' or Authentication error occurred(though entered correct password). After refreshing it goes up to obtaining IP address and then back to saved to secured.
I tried turning off power saving(*#0011#), forget and reconnect but nothing worked.
This is weird as this is location specific issue, not sure what to toggle. Looking for some expert advice.
Hi , pobably your phone is okay but you are not allowed to use those networks. Maybe someone had put the limits how many devices can be connected for example limit is 5 devices , and you are 6 person who is trying to connect and of course it will be just saved . If you are able , try to reset ruter to default settings , also try to onnect to your home network and see if is connecting. Last you can try is to do Factory Reset , but before that back up your data. Good Luck : )

There is no restriction as such, I'm not even able to connect to my colleague's mobile hotspot. Yeah, factory reset is the last option, looking for some hints before I do that.
