TP-Link Archer A20 (A20) specifications

Body

If you have limited space available for your router, such as in a small apartment or office, the dimensions can determine whether it can fit in the designated area or not. It's important to consider the physical size of the router, including its height, width, and depth, to ensure it can be accommodated in your space. The weight of router is not typically a critical factor for most home or office setups.

System

The Broadcom BCM4908 @ 1.8 GHz CPU, combined with other factors such as RAM capacity and firmware optimization, determines the overall performance and responsiveness of the router. The router's memory (512 MB) cannot be expanded. When choosing a router, it is important to consider both the flash memory and RAM specifications. The Archer A20 has 128 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 Archer A20 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 TP-Link provides the appropriate power supply (12 V / 5 A) that matches the voltage requirements of the router. The power supply unit is designed to deliver the correct voltage to the router, ensuring its proper operation.

Network

The Archer A20 router supports multiple networking standards to ensure compatibility with various devices and systems. The majority of networking equipment, including routers, switches, and other network devices, is designed to support IPv4. The Archer A20 router is also compatible with IPv6. IPv6 provides a significantly larger address space and offers various enhancements and improvements over IPv4.

The Archer A20 has 4 x 10/100/1000 Mbps LAN and 1 x 10/100/1000 Mbps WAN ports. The LAN ports of Archer A20 router are numbered and are used to establish wired connections between the router and devices such as computers, gaming consoles, smart TVs, network-attached storage (NAS) devices, and other network-enabled devices. Gigabit Ethernet ports of the Archer A20 router allow for faster communication between devices within your local network.

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 Archer A20 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

This router has 6 x 4 dBi, fixed antennas. Many modern routers feature multiple antennas and use Multiple-Input Multiple-Output (MIMO) technology. This technology enables simultaneous transmission and reception of multiple data streams, increasing overall throughput and improving the Wi-Fi performance. The Archer A20 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 Archer A20 supports 5 GHz signals. To optimize your Wi-Fi experience, it's often recommended to use a combination of both 2.4 GHz and 5 GHz bands, taking advantage of their respective strengths based on your specific needs and the devices you have. The Archer A20 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 AC4000 is a performance indicator that represents the router's theoretical maximum speed. The theoretical maximum speed (750 + 1625 +1625 Mbps) represents the highest data transfer rate that the router is capable of achieving under ideal conditions. The maximum TX power of Archer A20 router is 30 dBm. Adjusting the TX power of a router can be useful in situations where you want to optimize the Wi-Fi signal strength and coverage.

The Archer A20 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 A20 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. Once the guest network is set up on your TP-Link Archer A20 router, your guests can connect to it using the specified SSID and password. They will have internet access, while being separated from your private network.

Connectivity

USB ports can offer additional functionality depending on the router's capabilities. The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps), which is equivalent to 60 megabytes per second (MB/s). The USB 3 ports provide a fast interface for external storage with data transfer rates of up to 4.8 Gbps. The Archer A20 router has print server functionality. With a USB print server, you can manage printer settings, monitor print queues, and control access to the printer from a centralized interface. This can simplify printer management and administration tasks. The Archer A20 router allows you to schedule automated backups of your important data to the connected USB storage device.

Administration

The TP-Link router setup panel is accessed through a web browser. Connect your computer to the Archer A20 router via Wi-Fi or Ethernet cable. In the address bar of the web browser, type in the 192.168.0.1 IP address. 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.
