TP-Link Archer D9 (D9) 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.

System

The Broadcom BCM4709A0 @ 1 GHz CPU provides processing power to handle various tasks and services within the Archer D9 router. The 128 MB of RAM enables the router to handle multiple tasks and processes concurrently. It allows for the efficient switching and allocation of resources among different processes running on the router, facilitating multitasking and ensuring smooth operation. The flash memory in a TP-Link router is different from the volatile memory (RAM) that is used for temporary storage of data while the router is powered on. Flash memory of the Archer D9 retains its data even when the router is powered off, allowing the router to maintain its firmware and configuration settings across reboots.

To upgrade the firmware of the Archer D9 router, you typically need to visit the manufacturer's website, locate the specific model of your router, and download the latest firmware version provided. The firmware upgrade process may vary depending on the router model, but it often involves accessing the router's web-based administration interface and uploading the downloaded firmware file. The TP-Link packages the Archer D9 router with 12 V / 3 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

Like many modern routers, the TP-Link Archer D9 supports a variety of features and technologies to enhance your network connectivity and security. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The Archer D9 router also supports IPv6 protocol, allowing you to utilize the latest version of the Internet Protocol. The LAN ports are physical connectors on a Archer D9 router that allow you to connect devices to your local network using Ethernet cables.

Gigabit Ethernet ports support data transfer rates of up to 1 gigabit per second (Gbps), which is significantly faster than the maximum speed of 100 megabits per second (Mbps) supported by standard Ethernet ports. WAN ports are used to connect the router to your internet service provider (ISP). They typically use Ethernet cables or fiber optic connections to establish a high-speed link between your local network and the wider internet. The Archer D9 router supports Gigabit WAN. Having a Gigabit WAN port is beneficial when your internet service plan supports high-speed connectivity, as it ensures that your router's WAN connection can handle the maximum speed provided by your ISP.

Wireless

The 3 x 3 dBi, RP-SMA antennas of Archer D9 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. This router is 2.4 GHz compatible. The 2.4 GHz band is widely supported by a wide range of devices, including older devices that may not be compatible with the 5 GHz band.

This router is 5 GHz capable. The 5GHz band provides faster data transfer speeds compared to the 2.4GHz band. This is primarily because the 5GHz band has more available channels and less interference from other devices like microwaves or cordless phones. The Archer D9 Wi-Fi router offers fast data transfer speeds, suitable for demanding applications like streaming HD or 4K video, online gaming, and large file transfers.

The AC1750 is a performance indicator that represents the router's theoretical maximum speed. The theoretical maximum speed (450 + 1300 Mbps) represents the highest data transfer rate that the router is capable of achieving under ideal conditions. The TX power of Archer D9 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 Archer D9 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 Archer D9 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. The TP-Link Archer D9 router is capable of creating a guest network. Guests connected to the guest network usually have limited access to network settings and configurations. They are typically restricted from accessing devices connected to the primary network, such as printers, network-attached storage (NAS), or other shared resources.

Connectivity

USB ports can offer additional functionality depending on the router's capabilities. The USB 3 ports provide a fast interface for external storage with data transfer rates of up to 4.8 Gbps. By connecting a USB printer to the Archer D9 router, you can make it accessible to all devices on your network. This eliminates the need for individual printer connections and allows multiple devices to use the printer simultaneously. The USB file server functionality of this router allows you to connect external storage devices, such as USB flash drives or hard drives to your network. This enables easy file sharing and access among devices connected to the network.

Features

The RJ11 port allows you to connect your telephone line to the router. This enables features such as VoIP (Voice over Internet Protocol) telephony, where you can use internet-based voice services instead of traditional landline services.

Administration

The default IP address of this router is 192.168.0.1. 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.
