DHCP reservations for the printer ensure that it consistently receives the same IP address on the network. This facilitates easier management and security by allowing network administrators to configure firewall and network access policies based on the printer’s IP address.

Content filtering on a router allows administrators to block access to specific websites or categories of sites (such as adult content, social media, or gaming sites) based on the settings configured. This feature is designed to create a safer browsing environment, particularly in homes with children.

Changing the router’s default administrative password is the most critical first step in securing a home network. Default passwords are widely known and can be easily found by malicious actors, making routers vulnerable to unauthorized access and control.

A screened subnet, often implemented using a demilitarized zone (DMZ), is designed to add an additional layer of security to networks by segregating different types of traffic and providing zones with varying security levels. Placing the web server in the DMZ allows it to be accessible from the internet, which is necessary for its function, while isolating it from the internal network where sensitive data resides.

Universal Plug and Play (UPnP) is a network protocol that allows devices to discover each other and establish functional network services for data sharing, communication, and entertainment. Enabling UPnP on the router can improve a game console’s connectivity to online multiplayer games by automatically opening the necessary ports to facilitate seamless communication with game servers and other players. This setting helps eliminate manual port forwarding requirements and can resolve connectivity issues that hinder the gaming experience.

DHCP reservations can significantly enhance network management and stability for devices that need constant network access. By assigning a fixed IP address to each smart home device based on its MAC address, the router ensures that the device receives the same IP address each time it connects to the network. This stability can reduce connection issues and simplify the process of managing devices within the network, as each device’s IP address remains consistent, making it easier to identify and troubleshoot if needed.

IP filtering rules allow you to specify which IP addresses are allowed or denied access to your network or certain services within it. This can effectively enhance security by limiting access to sensitive devices or services to only known, trusted devices.

While changing default passwords, updating firmware, and enabling UPnP are important for security and device compatibility, adjusting the physical placement of the router is crucial for improving signal strength and network performance throughout the home. A router’s location can significantly impact the wireless coverage, with obstacles like walls and large metal objects potentially degrading the signal. Placing the router in a central, elevated position, away from large obstructions and interference sources, can help ensure more stable and robust wireless connectivity for activities such as video conferencing and large file transfers.

Firmware updates for routers often include critical security patches that address vulnerabilities discovered since the last update. These vulnerabilities, if left unpatched, can be exploited by attackers to gain unauthorized access, disrupt services, or perform malicious actions against the network and connected devices.
