blacklist rt2x00lib
blacklist rt2x00pci
blacklist rt2x00usb
to etc/modprobe.d/blacklist-rt2x00.conf
but i checked this and i have this folder now but wireless still doesn't work

thanks for ur help
In Ubuntu 12.04, rt2800pci is correct for your device. If you blacklist it, of course you will have no wireless because you will have no driver!! I suggest you remove the file:
sudo rm /etc/modprobe.d/blacklist-rt2x00.conf
Now reboot and tell us your symptoms.
