At Ubuntu dashboard( press window key ) search Additional Drivers , and it will search drivers for Wifi and more graphics driver , you can select first "Broadcom STA wireless driver" and install it and for more graphics also install ATI/AMD graphics driver.
Also try to visit this video to install driver:- http://www.youtube.com/watch?v=lsbUO_8MFfA
after install restart the Ubuntu . and
some times it will first time not search the wifi devise so sleep the pc for 1 min. and login again(but its rare case).
