I have made a USB bootable key installing from mini.iso (previous alternative install), thus key is crypted with llvm (I think is not the point but you never know) I installed gnome 3.8 (I think is not the point but you never know)

When I plug the key on both laptops (HP pavillon dm4 or Dell Latitude 6430u) I get nor wireless nor hard (via ethernet) internet connexion ! I have a desktop (not wireless) on which the ethernet work...

Do you have an idea of what I have to do to make it work, I am surprised this does not work out of the box... ?

Reading this post, I join some logs bellow

Here is the result of sudo lshw -class network
