A technician is setting up a network printer for a customer who has a SOHO router. The technician wants to make sure the printer stays connected in the future and is available on all the computers…

DNS settings are used to resolve hostnames to IP addresses, but typically a printer is accessed directly by its IP or via network discovery, and configuring DNS on the printer isn't the primary way to ensure stable connectivity.

Assigning a static IP address to the printer ensures that its network address remains constant, preventing DHCP-assigned addresses from changing over time. If the printer's IP address changes, computers configured to print to it via IP address will lose connectivity, making a static IP crucial for reliable, long-term network accessibility for all devices in the house.

WWAN (Wireless Wide Area Network) is used for cellular connectivity, which is not relevant for a printer on a local SOHO network.

A metered connection setting limits data usage and background tasks, which is not applicable or beneficial for ensuring a printer's persistent network availability.
