lspci
and grep
for network I see that my Network controller is a Realtek Semiconductor Co. device. What exactly does that device do? My Ethernet is working fine. Do I need to find a driver that will handle both wired and wireless connections for this network controller? Or do I need a Wi-Fi driver for the network controller because the network controller only handles Wi-Fi.lspci
identifies that as an Ethernet controller.03:00.0
at the beginning of the lspci
output is a bus/slot number for the device. Most likely, there is already a driver loaded. To check, look in /sys/pci/devices/0000:03:00.0/driver/module/drivers
; it will probably contain a symlink reference to something in /sys/pci/drivers
.
