unable to use wifi

Hi,I am new to linux and is unable to use wifi.my device is is rt3290

Your Linux distro is?

Hi Jerin

Welcome to the forum, can you be a little more specific about your problem as arochester said give us the distro and what is happening when you try to connect to wifi can you see your wifi listed in available networks

also can you post the output of

ifconfig

and

rfkill list
