The MediaTek MT7621DAT @ 880 MHz CPU provides processing power. It handles tasks and services within the AC2100 WiFi Gigabit router. You cannot expand the router's memory (128 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. The firmware upgrade process may vary depending on the router model. However, it often involves accessing the router's web-based administration interface. The D-Link packages the AC2100 WiFi Gigabit router with 12 V / 1 A PSU.

The router supports many networking standards. It ensures compatibility with different devices and systems. The IPv4 uses 32-bit addresses, represented as four sets of numbers separated by periods (e.g. 192.168.0.1). The router also supports IPv6. This allows you to use the latest Internet Protocol. The router has Gigabit Ethernet ports. They allow for faster communication between devices on your local network. A Gigabit WAN port is helpful. It is useful when your internet plan supports high speeds.

A well-positioned antenna can reduce interference and signal weakening. This leads to a more reliable connection. The 2.4 GHz band is widely supported by many devices. This includes older ones that may not work with the 5 GHz band. The 5GHz band provides faster data transfer speeds compared to the 2.4GHz band. This Wi-Fi router supports multiple spatial streams, typically up to 4 streams. The top speed, 300 + 1733 Mbps, is the highest data rate the router can reach. It's the theoretical limit in perfect conditions.

The introduction of WPA2 (Wi-Fi Protected Access 2) improved upon WEP. It provides stronger security. The WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security protocol. WPS (Wi-Fi Protected Setup) provides an easy method. It connects devices to a Wi-Fi network.
