Hi,
Sorry for taking so long to get back to you. About your first question. "lspci" lists all of the hardware that is connected to your computer with pci slots.
About your wireless, if you right click on your network manager, and them click on edit connections..., you will get a menu. This menu has some tabs: wired, wireless, mobile broadband, vpn, dsl. I am wondering what is listed under the wireless tab? This will help us figure out if you are finding anything.
Cheers!
