Hi, the wireless tab is inactive, so I made a little search and looks like I need to download a wireless firmware, I have an old pc, a Lenovo X230, I can't really find what wireless firmware is installed on it, I made this screenshot of my device manager in Windows:

I don't know which one is the wireless firmware, by the way if I get to find the firmware will I have to installed it manually ? has I can't download it with a "yum install" command because the Centos box does not have internet connection.
