Dual-Boot Kali Linux Wired Connection Not Working

Question

When I plug in a Category 5 cable to get an Ethernet connection, the system detects a wired connection. However, I cannot access the Internet.

When I choose to connect to the wired connection, the display that shows the WiFi connection is just a loading bar. I have been trying to figure this out for days.

Here is some information:

Iwconfig is used for wireless interfaces.

Use ifconfig to configure your wired interfaces, or use the network manager GUI built-in.

You can use lspci to see if there were problems loading the Ethernet drivers. Make sure what is listed is what you know the model of the card to be.

If you have further problems, Google & double check the compatible cards list for the Kali version you are using.
