ethernet driver cant be found

Driver disc included with motherboard? Download driver from motherboard manufacturer? Google mobo spec's and identify ethernet chip and download from chip supplier. At the very least, post device ID. Screenshot of your 3DP Chip result does not help. Device ID can be seen from 3DP Chip by clicking on Q&A/Bug, pasting into text editor of your choice. Will look something like this,
PCI/VEN_10EC&DEV_C821&SUBSYS_C82810EC&REV_00&CC_028000 Realtek Semiconductor Corp. Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC PCI bus 1, device 0, function 0 Net

3DP Chip user...

Please bug reporting with bug report button, and then paste the contents(
3DP Software >> Q&A/Bug(Click) >> OK(Click) >> "Paste(Ctrl + V)"
).

If you can't not connect internet and so you can't past the contents, you can use notepad with photo.

Thanks for using 3DP software!
