At home i got a gigabit router/1gbps internet connection that works like a charm on all my pcs and my windows phone, but on android i encounter quite a big problem. I got a Samsung Galaxy Tab 3 lite with 3g that can download and update apps with no problem over 3g but when i connect it to wifi it starts going berzerk, crashing all google apps and giving me error 491 when i try to download anything. Also I got two more android phones with 2.3 that can't get Whatsapp started over my wifi but over any other connection don't encounter any trouble, which i find very odd because my sister's 4.1.2 android has no problem with wifi at all. I don't even know where to start.. I tried playing with my wifi router settings with no luck.. Is it an android problem? And I don't even know if I should call my ISP retarded tech support and try to make them understand my problem or just try to install some custom rom and get rid of the stupid samsung-modified android 4.2.2 (also my main problem is the tablet)

Hello everyone
okay, i've been with a really anoying problem since the 2.3.x updates on android (Samsung Galaxy Gio in my case). The problem is that everytime I try to connect to the network, I stay some seconds with good connection and suddently the router just rebots himself. Tryed already changing some router settings (by the way my router is an Zyxel P-660W-Tx v3), setting the phone to factory, deleting apps and I always get the same result. I tryed to contact the Zyxel company but with no sucess until now. I know there's gotta be another fix than just have to buy a new router so it would be great if someone could help me out. Because this thing is freaking me out already.
Cumpliments,
Deviantor.
hi everyone,
my phone is a GT-I9300, android 4.0.4, Baseband I9300XXLFB (original, stock), Kernel vers. 3.0.15-782020-user[...], Build number IMM76D.I9300XXBLFB.
it seems that Samsung didn't only change the Search function through the update we got last week, but also disabled Tethering (I think).
the update was meant for the US version of S3 where the Tether option is sold separately by the operators but they also released it for the international version. I found Nexus users complainig abt the same issue after update.
does anyone know a fix for this? can someone reccomend a good custom ROM please
Thank you

"my S3 worked fine untill few days ago...I don't know what changed it, but my Wi-Fi doesn't work anymore. it gets connected to the router but I have no transfers (tried it on my router but also in many "public" Wi-FI). also, none of the Tethering options work (haven't tried them before 2 days ago, only after the Wi-Fi issue came up), none of the Wi-Fi, USB or Bluetooth (Tethering gets connected fine, but the connection has the exclamation mark and I have no internet on my PC). It might have happend after Samsung's update fix we got few days ago for searching or something, but I'm not sure."
Wi-Fi is working after I've done a reset on the router...but I don't understand how the hell my router affects other Wi-Fi connections. There seems to be a software glitch with the Wi-Fi somehow.

I tried the *#0011# command and switched off the "WIFI Power Save Mode" but that didn't fix it either.
I suppose it is a software problem as the phone (apparently) worked fine fot 3 weeks (I got it on the 7th July).
did/does anyone have this issue? please help me fix it and also, please reccomend a good custom ROM (or "the best" if there is such thing ).
Thank you very much for any help

According to your description, I'd say that your wifi chip's done
I'd call to local service/place you purhaced the phone and explain the problem.
Warranty should cover that kind of problems.
I just bought Galaxy S DUOS..I am loving the phone but i have a problem with WIFI. The mobile gets connected to network but and it also shows a working internet over the connected network. But When I try to browse net or use play store it works excellent for first 40-50 secs or 2 min or even sometimes 5 min. but then afterwards it won't work at all.Even if i queue a download during that first moments when wifi is working..after that it wont download the file.. The download just hang in between or gets interrupted..:crying:
As i just bought the phone i am not thinking of rooting it at least this early..And theres no any custom ROMS available for S DUOS anywhere yet..as far as i know..
Though i was wondering if i could extract the apk from any other S DUOS and then i can try flashing it with my device.. Actually I don't know much about it. I am just wondering if that can be done..Sorry if i said something very noob..
But seriously i need to fix my wifi.. help is really appreciated..
PS-Even i tried Fix my wifi app from the play store.. but it also didnt fix anything.
sol:
Even i faced the same problem with my home network .If your problem is resolved its okay but incase you are still facing the trouble
Check for this: is your wifi network protected then make it a open network and try. This resolved my issue , ofcourse I agree that making a wifi network open is Not suggestible
Hello,
i have phone with wifi problem, wifi turn on and find all network but can't connect.
i see MAC adress is 00;00;............
when phone imei, BT Mac adress etc are ok?
any idea? can i repair Mac adress or it's hardware problem.
Ok somewhat an obscure issue, and the fix that lets a VPN work over tether does not seem to fix it.
I first encountered this on I think 4.3 or 4.2 with my Galaxy Nexus prime. I would use a wifi hotspot, and all connections work fine except for when connecting my playstation Vita. It would say it could not login. So I do a connection test and everything is okay except the attempt to sign into playstation network.
I found maybe 2 other people with the same problem on different devices. I now own a rooted fire phone on 4.6.1. It too has this same problem. And it's believed by some that after 2.1 or 2.2 all native versions of wifi hotspot have this issue. I've tried treve mod, the vpn fix, and a handful of wifi hotspot apps with no luck. I don't know if these apps work as I could not establish even a normal connection through them.
I believe what I need is a kitkat compatible wifi app that doesn't rely on the native hotspot, or some way to modify it if anyone knows what's causing the blockage.
edit: To solve it on my old phone, I actually had to downgrade android to jellybean. I can't do that with this phone though.
Thanks for any help with this.
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.
