TP-Link TL-WR2543ND (TL-WR2543ND) 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 Atheros AR7242 @ 400 MHz CPU provides processing power to handle various tasks and services within the TL-WR2543ND router. The TL-WR2543ND comes with 64 MB of RAM. The amount of RAM in a router can impact its performance and capacity to handle concurrent operations and traffic. Higher RAM capacity allows for better multitasking, larger routing tables, and improved overall performance. The 8 MB flash memory in the router serves as the storage medium for the router's firmware. It is a non-volatile memory that retains its data even when power is removed from the device.

The TP-Link often releases firmware updates to enhance the router's functionality, improve security, fix bugs, and add new features. Firmware updates can provide performance improvements, compatibility with new devices or protocols, and address vulnerabilities. Alternative router operating systems often provide more customization options and advanced features compared to the default firmware provided by router manufacturers.

The TL-WR2543ND is an OpenWRT supported router. OpenWrt offers a wide range of features and capabilities that extend the functionality of networking hardware. It includes a package management system that allows users to install and manage additional software packages to add new features or customize the device's behavior. The TP-Link packages the TL-WR2543ND router with 12 V / 1.5 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 TL-WR2543ND supports many network standards too. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The TL-WR2543ND router also supports IPv6 protocol, allowing you to utilize the latest version of the Internet Protocol. The LAN ports are physical connectors on a TL-WR2543ND router that allow you to connect devices to your local network using Ethernet cables.

This router has Gigabit Ethernet LAN ports, which provides data transfer speeds of up to 1000 Mbps (1 Gbps) over Ethernet connections. The WAN port on a router stands for "Wide Area Network" port. It is used to connect the router to the external network, typically provided by an internet service provider (ISP). The TL-WR2543ND 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.

Wireless

The 3 x 3 dBi, RP-SMA antennas of TL-WR2543ND 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 capable. The 2.4GHz band refers to the portion of the radio spectrum between 2.400 and 2.4835 gigahertz. This frequency range is unlicensed and globally available for various wireless applications, including Wi-Fi.

The TL-WR2543ND 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 TL-WR2543ND is capable of a maximum throughput speed of 450 Mbps. The real-world speed of a TL-WR2543ND router is typically lower than its theoretical maximum speed.

The TX power of TL-WR2543ND 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 TL-WR2543ND 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

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). By connecting a USB printer to the TL-WR2543ND 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.

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. If you are unable to log in to the setup panel of your TP-Link router, performing a reset can be a helpful troubleshooting step. It is highly recommended to change the default password of your TL-WR2543ND 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.
