How to check Ethernet connection speed on your Mac

1. Make sure your Ethernet cable is plugged in, and confirm that you are connected to the network in System Preference > Network.
2. Locate the Network Utility on your mac. It is in Applications > Utilities > Network Utility. Alternatively, search Network Utility in Spotlight Search.
3. In the Info tab, under Network Interface, use the drop-down menu to select the Ethernet.
4. You should be able to view network connection details including network addresses, and connection link speed.

That’s it — easy as pie.
