How to check ethernet connection speed on the mac

The convenience of wireless networking is fantastic, but it doesn’t compare to the solidity and dependability of a wired network connection.

Where can you find out if your Ethernet connection is running at 10, 100, or 1000 Mbit/s? It is not in the most obvious place, as it turns out.

 

  1. Make sure your Ethernet cable is plugged in, and verify 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 all there is to it! It’s obvious after you know where to look. While in the Network Utility, check out other useful features of this app in the other tabs.

  • Ping: Lets you test how long it take to send a message to a remote server and receive a response. Measured in milliseconds.
  • Whois: Find out who is the registered owner of a domain name.
  • Traceroute: Trace the path your request physically takes along the Internet when you connect to a remote server.

    Hi, nice post.

    I have a doubt, maybe you can help me figure out. I have my MAC connected through a Devolo 200, which software reports I am connected at 180 Mbps to another Devolo which is also connected to a Gigabit switch.
    Then I have the information on OSX saying that I am connected at 100 Mbps. What happens with the other 80 Mbps the Devolo software accuses I should take advantage of?

    How does Network adapters work? If the Devolos offer the adapters connectivity between 100 and 1000 (something in the middle), will the adapters on both sides take advantage of this or if it never reaches gigabit it will remain always in 100 Mbps?

    Thanks for your comments,

    I forgot to mention the OSX has a Thunderbolt gigabit adapter.

    My Network Utility window does not indicate ‘Link Speed’ as you show, with ‘Info’ selected. Under Interface Information the list is this:
    Connection Status; IP address; Destination Address; Connect Time.
