Want to display internet speed in Ubuntu panel? I used to use an indicator applet in Ubuntu when the Unity desktop was the default. Now in Ubuntu 18.04 this can be done via a Gnome shell extension.
The Gnome shell extension system is a replacement for the “applets” or “widgets” system. Extensions can add their own items to the top panel. And NetSpeed extension display internet speed in Gnome panel.
To install NetSpeed extension, simply open Ubuntu Software, search for and install “netspeed”:
It displays internet speed in top-right system tray area once you installed the extension. For settings, go to Ubuntu Software -> NetSpeed -> Extension Settings.
That’s it. Enjoy!
