How can I check whether my bandwidth is used by others?

Hello!

As long as you do not use a wireless router to access the Internet, your broadband will not be used. If your broadband account is not bound to the line, your account will be stolen by others. When you dial the Internet, error 691 is displayed.

If you use a wireless router to share the Internet and download the network monitor in my space, this software can help you check that several computers are surfing the internet in the LAN, if you find someone using your network, you can change the security password of the wireless router.
