The Broadcom BCM4908 @ 1.8 GHz CPU is key. It, along with factors like RAM and firmware, decides how well the router works. You cannot expand the router's memory (512 MB). When choosing a router, it is important to consider the RAM specifications. A larger flash memory allows for more space to store configuration backups. Upgrading router firmware has become simple and user-friendly. The TP-Link provides the right power supply. It is 12 V / 5 A, this matches the router's voltage needs.

The 6 x 4 dBi, fixed antennas allow sending and getting many data streams at once. This boosts overall throughput and improves Wi-Fi performance. Many IoT devices, smart home devices, and older Wi-Fi devices mainly use the 2.4 GHz band. To optimize your Wi-Fi experience, it's often recommended to use a combination of both 2.4 GHz and 5 GHz bands. This Wi-Fi router supports multiple spatial streams, typically up to 4 streams.

The top speed, 750 + 1625 +1625 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions. WEP was the first Wi-Fi security protocol. But it is now seen as weak and easy to hack. The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.

Connectivity

The USB 2 port has a maximum theoretical data transfer rate of 480 megabits per second (Mbps). The USB 3 ports provide a fast interface for external storage with data transfer rates of up to 4.8 Gbps. A USB print server adds print functionality. You can manage settings, watch queues, and control access from one place. The Archer A20 router lets you schedule backups. You can back up to the connected USB storage device.

Administration

Changing the password often is a good security practice. It protects your network and devices from unauthorized access. Changing the default password improves your router's security. It reduces the risk of unauthorized individuals controlling your network.

Pros and Cons

Every router, including this TP-Link one, has its good sides and not-so-good sides. Let's take a closer look at both to get a full understanding of what this router can do. We'll talk about what it does well and also where it could use some improvements. Just remember, this is just what I think, and you might see things differently.
