[ubuntu] Caot coect to WIFI after installing Ubuntu 16.04

Hi,
I've just installed Ubuntu 16.04 on brand new desktop. Everything works, a part from WIFI. I don't see any network.

I've googled, and seen that it is a common problem, however, I have not been able to solve it.

Via etheet cable, I've updated the system. I paste below a bunch of info, hope usefull (lshw -C; wireless-info; lspci; network-manager)

My questions are:
1) Do I have a wireless card? I guess so...
2) If it is a software/driver problem, how could I solve it?

Obviously, I'm not an expert, just a normal user.

Thank you
j

1) lshw -C

Code:

Hardware Lister (lshw) - B.02.17
uso: lshw [-formato] [-opciones ...]
       lshw -version

        -versión de programa de muestra (B.02.17)

el formato puede ser
        - salida de estructura de hardware en HTML
        - salida de estructura de hardware en XML
        - salida de rutas cortas de hardware
        -businfo muestra información del bus

las opciones pueden ser
        -class CLASS solo muestra un cierto tipo de hardware
        -C CLASS es igual que «-class CLASS»
        -c CLASS es igual que «-class CLASS»
        -disable TEST desactiva una prueba (tipo pci, isapnp, cpuid, etc. )
        -enable TEST activa una prueba (tipo pci, isapnp, cpuid, etc. )
        -quiet no muestra el estado
        -sanitize sanea la salida (elimina información sensible tipo números de serie, etc.)
        -numeric muestra IDs numéricos (para PCI, USB, etc.)
2) sudo apt-get install linux-headers-generic build-essential dkms

DONE
