Table-2. Network interface list and hardware assignment.
Now that we have a bunch of interfaces listed but are unsure of whether we need firmware on not for them, as in if they have default
kernel and OS support or not, let's run a quick test. Running iwlist wlan0 scan in the terminal as root will show us if the wireless NIC
is working or not if various different SSID's are detected.
