Buffalo AirStation N450 DD-WRT (WZR-450HP2D) 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. If you purchase a router online or have it shipped, the weight may affect the overall cost. Heavier routers can result in higher shipping charges, especially for international deliveries.

System

The Qualcomm Atheros QCA9558 @ 720 MHz CPU provides processing power to handle various tasks and services within the AirStation N450 DD-WRT router. The AirStation N450 DD-WRT has 128 MB of RAM. Some advanced router features and software functionalities require a certain amount of RAM to operate properly. For example, routers with more RAM can support advanced security features, VPN services, or QoS (Quality of Service) prioritization more effectively.

The AirStation N450 DD-WRT has 16 MB of flash memory. A larger flash memory allows for more storage space to accommodate future firmware upgrades. The process of upgrading the firmware on routers has become relatively simple and user-friendly over the years. The Buffalo provides easy-to-use interfaces and instructions to guide users through the firmware upgrade process. The Buffalo packages the AirStation N450 DD-WRT 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 AirStation N450 DD-WRT router offers built-in security features to protect your network and connected devices. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The AirStation N450 DD-WRT router also supports IPv6 protocol, allowing you to utilize the latest version of the Internet Protocol. The LAN ports are physical connectors on a AirStation N450 DD-WRT router that allow you to connect devices to your local network using Ethernet cables.

This router has Gigabit Ethernet LAN ports. If you have a high-speed internet plan that offers speeds of 1 Gbps or higher, gigabit Ethernet ports are essential to fully utilize the available bandwidth. WAN ports often require specific configuration settings based on the type of internet connection provided by your ISP. The AirStation N450 DD-WRT router supports Gigabit speed on its WAN port, that can support speeds up to 1000 Mbps. This router ensures that you can fully utilize high-speed internet connections provided by your ISP. The AirStation N450 DD-WRT comes with built-in OpenVPN client. OpenVPN employs a certificate-based authentication system, which enhances security and provides a more robust method of identity verification compared to traditional username/password authentication.

Wireless

The 3 x 5 dBi, RP-SMA antennas of AirStation N450 DD-WRT 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 AirStation N450 DD-WRT 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 AirStation N450 DD-WRT 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 N450 refers to the maximum combined data transfer rate supported by the router across all Wi-Fi bands. The AirStation N450 DD-WRT is capable of a maximum throughput speed of 450 Mbps. The real-world speed of a AirStation N450 DD-WRT router is typically lower than its theoretical maximum speed.

The TX power of AirStation N450 DD-WRT 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 AirStation N450 DD-WRT router offers several security protocols: WEP, WPA, WPA2, WPS. 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. The AirStation N450 DD-WRT router offers WPS. The WPS (Wi-Fi Protected Setup) provides a simplified and convenient method for connecting devices to a Wi-Fi network. Instead of manually entering the Wi-Fi network name (SSID) and password, users can use the WPS feature to establish a connection with the push of a button or by entering a PIN.

Connectivity

The AirStation N450 DD-WRT router doesn't have file-server or print-server functionality.

Administration

The default IP address of this router is 192.168.11.1. 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. If you are unable to log in to the setup panel of your Buffalo router, performing a reset can be a helpful troubleshooting step. It is highly recommended to change the default password of your AirStation N450 DD-WRT router after the initial setup. If you forget the new password in the future, you may need to perform a factory reset on the router to revert to the default settings.
