In this tip we will see how to use the terminal under Ubuntu to display information about network devices used by your system. This information includes your device driver, firmware version, bus info, etc.

Getting Started

Let's first install the "ethtool" command line utility with this command from the terminal:

sudo apt-get install ethtool

To check information about your network adapter, use this command:

sudo  ethtool -i eth0

Here are outputs returned for my system:

~$ sudo  ethtool -i eth0
driver: e1000
version: 7.3.21-k8-NAPI
firmware-version: N/A
bus-info: 0000:00:03.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes

For a wireless device, you can check it with this command:

sudo  ethtool -i wlan0

Outputs returned for my wireless device:

~$ sudo  ethtool -i wlan0
driver: rt2800usb
version: 3.0.0-12-generic
firmware-version: 0.29
bus-info: 1-2:1.0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no

That's it!
