i8190 Internet disconnects - Galaxy S III Mini Q&A, Help & Troubleshooting

Hello guys,
I have a Galaxy S III Mini (i8190) with the official 4.1.2 ROM installed, i never installed a custom ROM on it and it was never rooter so: never modified,
The problem is that it is causing General internet Disconnects when it's connected to the WiFi. Not only the internet stops working on the phone, but also on all devices connected to the same router the internet drops.
I searched on several forums for a fix and some people suggested disabling "WMM" in router settings which works (the internet is stable); But i find WMM to be a very good feature and i want to keep it enabled.
I have also tried different routers and definitely the problem is not the router.
So i came here to ask anyone here to please! give me a real solution, that works with WMM enabled on the router.
Thank you for the will to help,
Gabriel

I experience continuously dropping wifi connections on my s3 mini while other devices have no issues
Hope flashing a custom rom will solve this...

Diamond WIFI HELP !!

Hi
I recently aquired a htc diamond. I've been having trouble connecting it to my router at home which is a netgear wpn-824.
I have tried a number of steps, tweaking the settings on the diamond e.g. changing the performance to best.
But it seems to jus keep on connecting and connecting then flips to unavailable then tries to connect again. The netgear is on unsecured at the moment so theres no password issue.
It seems like it tries to connect to the router but theres something stopping it at its' last hurdle
Does anyone have an idea or what to with my router. My router is dhcp enabled
I'd REALLY appreciate it if you could help as my brain is about to explode
THanks
sometimes routers get crazy if they are not turned off for a bit once in awhile
another option is to update the firmware of your router to the latests thats fixed
issues for many people
router
Hi Rudegar
Ive tried resetting the router and ive updated the firmware... no luck
Ive also tried installing wefi on my htc to connect to the router to see if that might work, but it does the same just keeps on trying it reaches 'verifying netgear' then it just restarts the connection.
Currently theres no restrictions on any mac addresses etc... so i dont see the reason why it isnt connecting
ANY help would be appreciated thanks

[Q] Internet connection problem

Hello everybody!
This is my first log in here, because I got a new Nexus One this weekend and I heard that your forum is one of the best about it.
So, I have a problem with the internet connection. My Nexus One is connected (the internet connection is exellent and I use it now with my laptop) but it just doesn't works. When I try to use the browser application or an another app, which needs internet connection, the application says that I have a problem with the internet and I can't use it. Any ideas ? Thanks!
Does it do this on all routers or just your home router if it's just on your home router?
It does this on all routers. Everything is okay now. It works fine. But that happens periodically and I don't know what's wrong with my phone. Now I'm trying to flash my phone from 2.2 to 2.3 and we'll see what will happens with it.
Ok well if you need any help with flashing the update (like if you're on a carrier tweaked ROM) then just ask.

[Q] wifi MAC is missing after doing factory reset

Hi everybody,
I'm having an extreme problem with the galaxy tab wi-fi. The thing is that, I bought my tab just 7 days ago and everything was fine. The only issue I got as usual like others in this forum or internet was the wifi adhoc problem.
So, I got over everything I could and found on this forum and from many others as well. I've tried the wpa-supplicant file replacement and the methods way described in this forum in all way. Finally, what I could get close was to make the connection between the tab and laptop adhoc hotspot. But no luck on getting the internet still.
Finally I thought of factory reset and doing this the main problem appeared. After doing the factory reset, it shows that the MAC address for the wifi is unavailable and so for the bluetooth as well. I am just stunt to see this and no way I can get back to my original state. So, it's currently a tab without a wifi. Please help me or guide me to the solution of this problem to recover my wifi mac address and to make connection with the ad-hoc connections.
For your note, the android version was froyo (2.2), never updated to any other. I also have the galaxy S II which runs on Gingerbread (2.3) and that doesn't have any kind of problem with adhoc networking or so. That just gets connected through connectify straightly.
Please back up me with your solution available and thanks in advance for this.

tethering issue

Hi All
I surf on internet to find someone with my issue but all the solution I tried did not work, so my situation is this:
I bought an S3 with Three mobile I unlocked so I can use different networks and I also update the S3 with official rom (4.2.1) using Odin hoping that this will make work the tethering but unfortunately the portable hotspot still not working which means the PC can connect to the Phone but the internet connection is not available, I tried to install some apps like foxfi but the issue still there, now I hope that here I can find some help
Thanks

[Q] Cable modem/router: Wifi signal ok but no connection

Hi guys,
My phone: Samsung Galaxy S3, GT-I9305, Android 4.1.2
I changed the ISP (Germany: To Unitymedia) and are now supposed to use a cable modem which as well serves as wifi router. My hardware is TC7200 (Technicolor).
After setting up everything, the wifi connection to Win 7 laptop and Apple iPhone/iPad is working fine (also LAN connection to laptop of course).
The S3 showed a funny behavior: It is possible to establish a wifi connection and it gets IP address assigned. Default gateway, DNS server looks all fine. However, this is only the wifi signal but not an internet connection. It is not possible to reach any website.
The strange thing: If the google site is cached (from a different connection and then switching back to this problematic one) I can run a google search and get results displayed. However, it is not possible to open any websites displayed as results here.
I tried several things based on suggestions in the net, like restarting the s§, using static IP address, changing wifi ports, disabling wifi encryption completely, restart the router, factory reset the modem/router. Finally I performed a factory data reset for the S3 but this as well, like all other things, did not help. The phone was never rooted until before yesterdays factory reset, because I wanted to use Titanium Backup which requires root rights.
Of course, in all other wifi networks so far, this S3 works absolutely fine!
I am not sure if this matters at all, but with the new ISP I got an IPv6 IP address while before I had IPv4.
To be honest, it might simply be a hardware problem which has to be fixed by Firmware upgrade by ISP. This problem is sort of known to them and when I called in they promised a firmware update in November. But anyway, it would be interesting to understand more about it and usually there is a solution for everything Nevertheless, I couldn't find a solution in any forum yet.
Any suggestions / ideas welcome.
Thanks!
EDIT:
Post already moved.
Reads like wrong settings more than hardware .
WiFi is kernel you can flash a kernel .
But i would reboot router and phone then set up wifi with no security first .
