What is Ethernet?

Ethernet connects devices in a local or vast area network. The wired network transfers data at hospitals, campuses, and other small buildings.

When an individual uses an Ethernet cable, they can plug it into the existing port. However, the process is slightly different for connecting an Ethernet adapter to MacBook. Here is the process.

  1. Firstly, observe both ends of the Ethernet adapter. You do not need to apply too much pressure as it may damage both ports. 

  2. Secondly, insert the USB plug of the adapter into the Macbook. Ensure that it’s plugged in correctly. And then, insert a LAN cable into the Ethernet port on the adapter. 

  3. Plug the other end of the LAN cable into the internet modem. You can also connect it to another device to establish a secure connection.

  7. Choose “Using DHCP” if the ISP automatically provides you with the IP address.

  8. You may also need to enter DNS settings which you can do on the sidebar. 

  9. You can also input WINS settings after selecting the option in the sidebar.

How to troubleshoot the Ethernet issue on MacBook?

Do not panic if your MacBook is not connecting to the Network via Ethernet. Here are some possible causes of connection problems. Take a look below.

Check the connection

Firstly, is your MacBook having difficulty recognizing the cable? Your cable may be the culprit, which is refusing to establish a connection. The individual must ensure the cable is securely inserted into the port. Subsequently, turn off the computer and unplug the Ethernet adapter. Wait a few minutes. Turn on all devices and reconnect the cables. 

Check the Ethernet adapter.

Secondly, the Ethernet adapter on MacBook may also be part of the issue. Try switching the settings to fix the issues. If nothing works, try installing a different adapter. Besides you can also contact a computer professional or your internet service provider.

Check the Internet

If you have the proper settings and the computer recognizes the devices, the connection is still disturbed because the Internet is down. Therefore, call the service provider to verify the connections. You can check the internet connectivity on your phone or another computer that shares the same Network. Check if the modem is working too. The issues reside at the back end if other devices cannot connect to the Internet.

Check Ethernet cable

The Ethernet cable could also be part of the issue. In certain circumstances, the cable does not build a connection. If the connection drops unexpectedly and the settings are correct, you can narrow the issue to the cable with trial and error. Therefore, you may need to replace the cable or check for bends that hinder connectivity.

Check Ethernet settings

The most apparent reason for Ethernet connectivity issues is the settings. Observe the following pathway to configure the settings.

  • Go to System Preferences or System Settings on the MacBook.

  • Select Network and then Device Name.

  • Open the Advanced Tab and ensure the settings are accurate.

The Bottom Line

With straightforward steps, installing an Ethernet adapter for MacBook does not require professional assistance. Connect to a device or create a wired connection. You can do it expertly. The only thing you need is an Ethernet adapter for an updated MacBook.
