If you are wondering, “Why does my computer show network activity when I don’t have wireless or any wires in my computer?” then you’ve come to the right place. In Windows 10, you’ll see a network icon located on the right side of your taskbar. This icon changes from a globe to a computer or WiFi icon depending on the status of the connection. The network icon on your computer’s taskbar displays whether you’re connected or not. If you’re connected to WiFi, the icon will be solid. If your connection is a private LAN, it will display a different icon. As to the activity, that is the computer’s operating system and applications trying to send and receive. Just because you do not have connectivity, does not mean the computer will not try to communicate.
