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,
