I do not have a lan card working  so as to  connect to it and use.Any
how I want to use the wifi so what do I need to install on it.
I will need to download any thing in the windows OS only (my laptop is
dual boot) and then install in Ubuntu.
So how should I go on.
lspci out put of my device is

Install package linux-firmware-nonfree.

I'm confused (not unusual). How do you do this if there is no working
wifi under ubuntu? Is the package on the cd? If so you should have
mentioned this.

No it is not on CD.Any thing that is important to make your wifi is by
default not present in the ISO which I downloaded.
So I rebooted the machine to Windows (I have a dual boot) wifi was
working in Windows so I went to the site and manually downloaded the
linux-firmware-nonfree package in windows then rebooted to Ubuntu and
the double clicked on the .deb file which then installed the concerned
While doing so I did not had any connectivity to internet from within
Ubuntu as only wireless network is available since I had windows so I
was able to reboot and download the non-free firmware for Ubuntu and
reboot then install in Ubuntu and then got wifi working.
