I encountered this problem as well. In many cases I've seen that you must connect an internet cable to the laptop, install some drivers and you're done, but in my case, my laptop doesn't have a network cable input (ASUS X509FB). How can I solve this?

Pages 24-25 of your manual https://dlcdnets.asus.com/pub/ASUS/nb/X409FA/0409_E15108_X409_X509_A.pdf shows there's a USB-C port. If one came with the PC, please connect the USB-C to Ethernet adapter to that port and use that to connect to your wired network to get drivers.
