First of all, thank you to search this posts for me. Thanks a lot! I downloaded the correct driver for my adapter (linux version) and I followed all steps, but unfortunately some commands didn't work:

sudo rmmod rt5572sta
sudo modprobe rt2800usb

hi! yes, my Vaio have a physical switch to turn the wifi on and off, but this switch don't work... and my laptop don't have a short cut key to turn on and off Wifi, like using Fn + (other key)
Im trying install the driver, but is not easy for me. Because the archives are all in .exe format, so Im trying to use Wine, but isn't easy neither to install that without internet conection...
Im not sure about that, so:
