Find Out Network Adapters Available in Ubuntu Linux

Wondering which network adapters you are using in Ubuntu or any other Linux OS? It is very easy to to find out the manufacturer of the network adapters in your computer in Linux. Open a terminal and use the following command:

sudo lshw -C network

If the above command doesn’t work with sudo, remove the super user privileges. Weird but helps. The output of the command reads like this:

Find out network adapter in Linux

As you can see, the wireless network adapter in my Macbook Air is BCM4360, a troublesome wireless adapter because of which often Ubuntu does not detect wireless networks.

lshw command actually used to list hardware in Linux and hence the command is named lshw. With the option network, it filters the result for networking hardware only.

Alternate method to know the network adapter

Alternatively, you can use lspci command that displays the information about PCI buses in the system. You should not need super user privileges to use this command. Just type the command in terminal:

lspci

The output of the command reads as:

These command gives you information about both wired and wireless network adapters. You might have noticed that there is no wired network adapter for my system in the output above. The reason is that I am using a Macbook Air and it does not have an Ethernet port.

I hope this quick post helped you to find the network adapters in your Linux system. Any questions or suggestions are always welcomed.
