How to Connect to Ethernet on PC or Mac

Connect to Your Modem or Router

1. Connect your modem to the internet cord. Connect the cable, DSL, or Fiber optic line from the wall to your modem.
2. Connect your modem to the router. If you are using a separate wireless router, use an Ethernet cable to connect from the modem to the internet port on your router. The internet port may be labeled "Internet", "WAN", "UpLink", or "WLAN". A lot of modern modems act as a wireless router. If you are not using an external wireless router, go ahead and skip this step.
3. Check to make sure your modem/router is online. Check the lights on the front of the modem/router. The lights labeled "Power", "Internet/Online" and "US/DS" light should be solid. If they are blinking, your modem/router is not connected to the internet. You may need to contact your service provider for assistance.
4. Connect an Ethernet cable to the modem/router. Connect one end of the Ethernet cable to the port on the modem/router that is labeled "LAN".
5. Connect the other end of the Ethernet cable to your computer. You computer should have an Ethernet port on it. On laptops, it's usually located on the left side or right side of the keyboard. On towers and all-in-one monitors, the Ethernet port is usually located on the back of the device.
