You showed us your Ethernet card.The description of my Wifi card by 'lspci' starts with "Network controller:" and would not be retained by 'grep net', which is case-sensitive ('grep Net' would catch it) unless option -i is used ('grep -i net' would catch it).
You can show us the unfiltered output of 'lspci' (i.e., just type 'lspci') but don't hold your breath: there certainly is no free driver or firmware for your Wifi card.
