Question about ASUS ProArt X670E-Creator Wifi

There is a CD/DVD inside the manual and with it. https://www.youtube.com/watch

I didn't have a CD/DVD with me. But yes, you hardly need one these days.
However, there may be cases where Windows does not automatically recognise network drivers under Windows 10, for example.
This means you have to download the drivers from another PC and put them on a USB stick.

A CD/DVD is not listed in the manual under package contents on page 13 https://dlcdnets.asus.com/pub...
You get everything you need as an up-to-date download.

Very few people still have a drive for optical media. And it is probably better to download the latest drivers from the manufacturer if they are needed at all, most operating systems should recognise the hardware.
