Linksys WRT120N (WRT120N) specifications

Body

If you plan to move or travel frequently and need to take your router with you, the dimensions become important for portability. Smaller and more compact routers are generally easier to transport, while larger routers with external antennas or multiple ports may be bulkier and less convenient to carry. The weight of router is not typically a critical factor for most home or office setups.

System

The Atheros AR7240 @ 400 MHz CPU provides processing power to handle various tasks and services within the WRT120N router. The router's memory (32 MB) cannot be expanded. When choosing a router, it is important to consider both the flash memory and RAM specifications. The WRT120N has 2 MB of flash. A larger flash memory allows for more space to store configuration backups. It enables you to save multiple versions of your router's configuration settings, which can be useful for restoring previous configurations or reverting changes if needed.

Within the WRT120N router's interface, look for a section related to firmware or system settings. The exact location and wording may vary depending on the router's make and model. The Linksys packages the WRT120N router with 12 V / 1 A PSU. A good PSU is an essential component of a computer or electronic device that converts electrical power from an outlet into the appropriate voltage and current required to power the internal components of the device.

Network

The WRT120N router supports multiple networking standards to ensure compatibility with various devices and systems. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The LAN ports are physical connectors on a WRT120N router that allow you to connect devices to your local network using Ethernet cables. WAN ports are the entry point to your local network, making them a potential target for unauthorized access or attacks. It's important to secure your WAN connection by using strong passwords, enabling encryption protocols, and keeping the router's firmware up to date to mitigate security risks. The WRT120N is equipped with Fast Ethernet WAN port, which have a maximum speed of 100 Mbps.

Wireless

The internal antennas of WRT120N influence the quality and stability of the Wi-Fi signal. A properly positioned and well-designed antenna can minimize interference and signal degradation, leading to a more reliable and stable connection. The WRT120N is compatible with 2.4 GHz Wi-Fi. Many IoT (Internet of Things) devices, smart home devices, and older Wi-Fi-enabled devices primarily operate on the 2.4 GHz band.

The WRT120N is a Wi-Fi 4 router, with slower data transfer speeds. This can result in slower downloads, video buffering, and reduced performance when multiple devices are connected. The N150 is a performance indicator that represents the router's theoretical maximum speed. The theoretical maximum speed (150 Mbps) represents the highest data transfer rate that the router is capable of achieving under ideal conditions.

The TX power of WRT120N can be adjusted by the user or set automatically by the router firmware. Higher TX power values indicate stronger signal transmission, which can result in a larger coverage area. The WRT120N router offers several security protocols: WEP, WPA, WPA2. The WEP (Wired Equivalent Privacy) was the first security protocol for Wi-Fi networks but is now considered weak and easily compromised. It uses a static encryption key and has known vulnerabilities, so it is no longer recommended for securing Wi-Fi networks. The WPA2 (Wi-Fi Protected Access 2) was introduced as an improvement over WEP and provides stronger security. If WPA3 is not available, WPA2-Personal with AES encryption is still considered secure.

Connectivity

The WRT120N router doesn't have file-server or print-server functionality.

Administration

The default IP address of this router is 192.168.1.1. Explore the router's configuration interface to access more advanced settings such as port forwarding, DHCP settings, parental controls, firewall settings, and QoS (Quality of Service) settings. Regularly changing the password is a good security practice to protect your network and devices from unauthorized access. It is also recommended to use strong, unique passwords for other devices and online accounts connected to your network for enhanced security. By changing the default password, you improve the security of your router and reduce the risk of unauthorized individuals gaining control over your network. It helps prevent unauthorized access to your router's settings, network configurations, and sensitive information.
