When for some reason our distro fails to auto install our wireless network card, we first need to identity its chipset, so open up a terminal and type:
lspci | egrep -i --color 'wifi|wlan|wireless'
In my case the results returned were
02:00.0 Ethernet controller: Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)
In this take notice the 02:00.0 at the beginning and now let’s find out the wireless card driver information
lspci -vv -s 0c:00.0
