Windows 10: "An Ethernet cable looks like a telephone cable..."

I just finished my first build, and have a couple problems. One of them is I do not have access to wifi on my computer. There is only a option for Ethernet. When I troubleshoot, it tells me "An Ethernet cable looks like a telephone cable with longer connections on the ends..." But I have wifi antennas, not an Ethernet cable. How do I get access to wifi?

Ethernet cable not working.

You need to solve your problem one step at a time, e.g. like so:

• Connect your CAT5 cable directly to your router. If it does not work, replace the cable.
• Connect the cable to your TP-Link wall plug. If it does not work, reconfigure or replace the wall plug.
