D-Link DIR-809 (DIR-809) specifications

Body

The dimensions and design of a router can impact its cooling capabilities. Routers with larger dimensions may have more space for internal cooling mechanisms, such as larger fans or heat sinks, which can help dissipate heat more effectively. The weight of router is not typically a critical factor for most home or office setups.

System

The D-Link DIR-809 router is equipped with Realtek RTL8881AN processor. The router's memory (64 MB) cannot be expanded. When choosing a router, it is important to consider both the flash memory and RAM specifications. The DIR-809 has 4 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 DIR-809 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 D-Link DIR-809 router comes with 5 V / 1 A PSU. This unit is responsible for providing electrical power to the router, and if it becomes faulty, it can be replaced with a new, compatible one.

Network

The DIR-809 router supports multiple networking standards to ensure compatibility with various devices and systems. The IPv4 is the fourth iteration of the Internet Protocol (IP) and is the most widely used version of IP on the internet today. The D-Link DIR-809 has 4 x 10/100 Mbps LAN and 1 x 10/100 Mbps WAN ports. LAN or Ethernet ports (RJ-45) are used to connect devices to the local area network (LAN).

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 WAN port on the DIR-809 router is a Fast Ethernet port, not a Gigabit Ethernet. The Fast Ethernet ports are capable of supporting speeds up to 100 Mbps, which is still suitable for most internet connections.

Wireless

This router has 3 x 5 dBi antennas. Antennas play a significant role in Wi-Fi performance and coverage. They are essential components of wireless routers that transmit and receive radio signals to establish wireless connections with devices. The DIR-809 is compatible with 2.4 GHz Wi-Fi networks. 2.4 GHz is the most widely used frequency and in some cases may be overcrowded. The 2.4 GHz band is heavily utilized by various devices like cordless phones, Bluetooth devices, and microwaves, leading to higher interference levels. The 5 GHz band is less congested, resulting in reduced interference and a clearer wireless signal. The DIR-809 router is 5 GHz capable.

The DIR-809 Wi-Fi router supports multiple spatial streams, typically up to 4 streams. This allows for higher data throughput and improved performance, especially when multiple devices are connected to the router simultaneously. The AC750 is a performance indicator that represents the router's theoretical maximum speed. The theoretical maximum speed (300 + 433 Mbps) represents the highest data transfer rate that the router is capable of achieving under ideal conditions.

The TX power (20 dBm) of a router refers to the transmission power or signal strength at which the router broadcasts its Wi-Fi signal. It determines the range and coverage area of the wireless network. The DIR-809 router offers several security protocols: WPA, WPA2. 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 DIR-809 router doesn't have file-server or print-server functionality.

Administration

The default IP addresses of the D-Link DIR-809 device is 192.168.0.1. These address allows you to access the router's console login page. 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.
