Ethernet not working out of the box

Hello,
I am sorry if this topic has been discussed, but I could not find a way searching the topics. (Please let me know how if there is a way).

I cannot connect to the network through ethernet. The WIFI works, but I need the wired ethernet connection. I searched google, tried a few, but I have not yet found a solution, and I wonder if this is a hardware problem.

Thank you

The default for wired ethernet should be to request an address via DHCP. Your router logs should show the request. What is the output you get from “ifconfig” and “route”?

I’m thinking that perhaps WiFi is mucking with things via NetworkManager and it thinks you don’t want to use wired since you have WiFi.

Also, does your router have any security settings, e.g., does it require a MAC address be entered?

Thank you for your replying.

The network connection still fails even with the WiFi disabled.
I don’t think there is any security settings.

Here is the ifconfig output. No output from route.

According to that wired network was never assigned an address (a function of the router is to reply to a DHCP request and provide an address). Either the DHCP request did not go out, or the router did not reply. The next step would be to look at the router logs. It is quite possible that WiFi setup disabled this function (even if you don’t currently have WiFi running), but you won’t know unless you check your router.

Hi ysuh,

Have you clarified and resolved this network issue?
Any result can be shared?

Thanks
