I have several computers using the WiFi here, but only my laptop has the Shaplus Bandwidth Meter. Does the Shaplus Bandwidth meter only monitors my laptop or just the household Internet in general?
The application is used to monitor the Internet speed and connections only on your computer. It doesn't have the capability of monitoring the whole Internet network. You can check the stats of the whole network in the router's interface (if you're using one). Access the official website to find more information about the software and its available features.
