In this tip we will see how to use the terminal to check information about your network adapters under Ubuntu. This may help you choose the correct driver to use with your wired or wireless network adapter.

Open the terminal (Ctrl+Alt+T) and run this command:

sudo lshw -C network

The output returened will be similar to this:

~$ sudo lshw -C network
