you can also connect your laptop directly in the media converter RJ45 port, manually assign your laptop LAN settings, ping 8.8.8.8 and open a website.

Yes direct connect media converter RJ45 to laptop internet working speed fast but connect router then configuration not working internet not ping G/W only LAN area connect show no internet
