Your home network appears to have slowed down significantly. In the home router GUI, you notice that an unknown host is connected to the network.
What should you do to stop this specific host from connecting to the network again?
MAC address filtering can deny network access to the specific device based on its MAC address. IP-based blocking is not device-specific because the host can receive or configure another IP address, and changing the SSID does not directly prevent that host from reconnecting.
