I can't connect through My wireless adapter

Hello Everyone, I just started using Ubuntu Mate and I can't connect to the internet. It shows Ethernet Network disconnected . I have a wireless adapter(realtek semiconductor corp. USB2.0 Hub

Hi Penguinman,
have you tiped wifi keys on keyboard and intro password, for ex. Fn+f2? Or does you connect ethernet wire directly?

I have not tried the wire keys

Ok, for wifi probably you must do it. If not, connect ethernet wire directly. Wifi card could need some realtek ubuntu drivers.

I tried My wifi key but My laptop is frozen

I trieed the wifi key but It did not work
