I'm desperate about this already... Problem: my samsung (title and: GT-S6012) turns off WIFI... I know it connects to router, because I managed to upload some photos to dropbox while WIFI is still on. But it stays on for around 1-5 seconds, then WIFI is turned off, when I try to do something what requires WIFI it turns on and again, off... That's not all. I thought, well... I'll just reinstall OS, funny thing is: USB connection don't work properly (tested on windows 7 64bit AND windows xp 32bit). Sometimes it connects perfectly (on win7 64bit), I can use even KIES, but when I started to reinstall OS, well... KIES (my suspicions) during reinstallation disconnected my device and windows failed to reinstall driver, so it wasn't connected and reinstallation failed. Now I have 'missing ID' error. So, what options do I have? Because I don't see any way how I could reinstall OS, even If my device will get new android version (4.1, I'm with 4.0.4). Unless there's a way to do this without KIES (restarting my computer fix USB problem, but I can't reconnect it to USB because it fails to connect second time). I know one thing, I hate samsung, my next smartphone will be googles android only because they're developing OS and I hope they can make it work with their devices.
