The link speed of an interface corresponds to the maximum speed of communication between a specific device and a wireless router. Obviously, the larger this speed is, the more efficiently your device will be able to communicate with the wireless router. For this article, we want to show you the different methods of finding the interface link speed on a Linux Mint 20 system.
Ways of Finding the Interface Link Speed in Linux Mint 20:
The quickest two methods of finding the interface link speed on a Linux Mint 20 system are described below:
Method # 1: Using the “ip” Command:
By using the “ip” command in Linux Mint 20, you can easily find the interface link speed in the following manner:
$ sudo ip addr | grep qlen
The interface link speed of our “enp0s3” interface is 1000 Mb/s as highlighted in the image shown below:
Method # 2: Using the “ethtool” Utility:
The “ethtool” is a built-in Linux utility that can be used in the following manner to find the interface link speed on a Linux Mint 20 system:
$ sudo ethtool NameOfInterface
Here, you have to provide the actual name of the interface in place of the NameOfInterface. For example, we wanted to check the link speed of the “enp0s3” interface.
The interface link speed of our specified interface is shown in the image below along with some other relevant information:
By following any of the two methods shared in this tutorial, you can easily find out the interface link speed of any specific interface in Linux Mint 20. The first method is more generic since it lists down the link speeds of all the available interfaces whereas the second one is more specific since you have to mention the interface whose link speed you want to find out while following this method. However, for any particular interface, both of these methods will produce the very same results. Therefore, you can follow either of them without any worries.
