Return to Question

I am new to Ubuntu and I have problems with my Ubuntu 14.04. I plugged my wifi adapter but it did not work so I guess I need to install the driver manually but I don't know how to do it. I currently don't have an internet connection in that PC since the wifi adapter does not work and I cannot connect through ethernet cable.

These are the things I've tried so far (still did not work):

• Installing the ath9k driver from a tar.gz. I followed this
• Following this for installing the rt2800usb. I had errors on sudo modprobe -v rt2800usb saying "error could not insert rt2800usb invalid argument"

I appreciate your suggestions

EDIT: Here is what my wifi adapter looks like for reference.
