Recently bought a Windows PC. It is able to connect Internet via Wifi but not from Cat5e cable.

This Ethernet cable was used by my Macbook before and it worked fine.

I use a NBN router.

When I run diagnostic, it gives me:

Plug an Ethernet cable in to this computer. An Ethernet cable looks like a telephone cable but with larger connectors on the ends. Plug this cable is to the opening on the back or side of the computer. Make sure the other end of the cable is plugged in to the router. If it does not help, try using a different cable.

Then I bought another brand new cable, and it still gives me the same crummy diagnostic.

  • Have you tried reinstalling the ethernet driver instead? Sometimes reinstalling drivers may solve the problems like this. Dec 27, 2015 at 8:29

Make sure your ethernet IPv4 properties are not set to a static IP address (unless you know exactly what network your router is on, and know about networking/subnets etc.). I would recommend setting your IPv4 IP address properties to DHCP on your ethernet adapter. It seems like your wifi is using the 10.0.0.x network so your ethernet adapter should pull a similar address from DHCP.

    this makes a ton of sense from what the ipconfig output says.192.168.131.x is also a super wierd ip range.
