Welcome to Android Central! Does this happen with any wi-fi network, or just your home network?

it happens with any wifi network sadly and right now the adapter wont even turn on now

That sounds like either a problem with the firmware or the hardware. I'm not sure if you can reinstall the firmware using Sony PC Companion, but it's worth a try: Update your software using PC Companion – Sony Xperia™ ray support (English)

Otherwise, you'd have to bring it to a repair shop. If you're lucky, maybe it's just a loose connection somewhere.

i did give them to a certified repair shop for sony and they installed a new software already but the wifi just worked only for just one day then here we go :/

They installed new software only? Did they actually look at the hardware? Bring it back to them and tell them the problem is still there.
