    Try this: download firmware-ralink from here: ftp.us.debian.org/debian/pool/non-free/f/firmware-nonfree/… , install wireless-tools if you haven't already (sudo apt-get install wireless-tools) and install the driver with sudo dpkg -i firmware-ralink_0.44_all.deb. – Jos Oct 16 '15 at 11:59

Thanks for your quick response and support. I think driver was already installed by Ubuntu 15.04, In terminal I wrote "rfkill list" found that it was hard off in terminal wrote "rfkill unblock all" and here I am using wifi without any problem.
