Well, I'm not sure what's the difference between the two. I simply
wanted to have a laptop connected to a wired interface, and render the
internet via a Wi-Fi to other devices.

user at liv-laptop:~$ lspci | grep -i athe

Wireless Network Adapter (PCI-Express) (rev 01)
02:00.0 Ethernet controller: Atheros Communications Inc. AR8132 Fast
Ethernet (rev c0)
Is this good, or bad?
