You are setting up a home office network and want to prevent unauthorized devices from connecting to your wireless network. What is one of the first steps you should take in the router settings?
Enable IP filtering
Change the default password
Turn off Universal Plug and Play (UPnP)
Disable SSID broadcast
Changing the default password is crucial because default passwords are well-known and easily exploited by unauthorized users. IP filtering prevents unauthorized devices by allowing only specified IP addresses. Disabling SSID broadcast does not prevent connection if the network name is known. Universal Plug and Play (UPnP) settings are more relevant to device communication within the network than to preventing unauthorized access.
