Our Plugable USB Ethernet adapters are a great way to add wired Ethernet connectivity to your MacBook via USB! Once drivers are installed and the adapter is properly plugged in you should get a connection. But, sometimes there are exceptions, and you may need to manually add the adapter to your network devices to be able to use it. This is easy to do, so let's get started!

Manually add the adapter

  1. Plug the adapter into your mac, and go to the Network Pane by clicking on the Apple Menu >System Preferences > Network. Then, click the plus button in the bottom left corner of the screen which will open a box to add the new adapter. Manually Add Ethernet Adapter To macOS

Renew the DHCP Lease

The Dynamic Host Configuration Protocol (DHCP) should automatically request and assign an IP address to the adapter when its plugged in, but this isn't always the case. Renewing the DHCP Lease will manually request an update to the IP address configuration to let you get online using the adapter.

  1. Open the Apple Menu > System Preferences > Network > Advanced...> TCP/IP. Then, click Renew DHCP Lease.Manually Add Ethernet Adapter To macOS
