I picked the chipname:

and searched in google, to verify if it was really a wifi chip. H-node is a good source for hardware reseach.

Finally i found here: that my chipset was supported.

I extendet /etc/apt/sources.list with the following line:

and performed another two commands:

The following command first removes the iwlwifi module from the limux kernel and then adds it to the kernel.
