I have four Windows 10 PCs. On two of them, I see a rectangle in the system tray with the upstream/downstream traffic, but the other two show only the application icon. How do I get those to show upstream/downstream traffic as well?
Generally, for the real-time bandwidth information in the taskbar:
The NetGenius Taskbar Extension must be selected during the installation.
The installer attempts to enable the extension automatically. If that fails, it can be enabled manually by right-clicking an empty space on the taskbar and choosing Toolbars - NetGenius Extension.
