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.
Indicator Network is a stupid traffic monitor applet for Ubuntu Unity, inspired by the old netspeed GNOME applet.
It displays the total current network traffic on system tray area on panel and you can check out the current download & upload speed from its drop-down menu.
The indicator will be put left of all your other indicators. If this is undesirable, the ordering index can be changed in gsettings:/apps/indicators/netspeed (use dconf-editor, available in Software Center).
To install this indicator applet:
Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, choose one method from below and run the commands one by one:
