Verdict

The D-Link DIR-825 is an AC1200 dual-band Wi-Fi gigabit router designed for home and small office environments, delivering combined wireless speeds of up to 1200 Mbps (300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz). Its core specifications include 802.11ac Wave 2 technology, one gigabit WAN port, four gigabit LAN ports for high-speed wired connections, and a multifunctional USB 2.0 port that supports 3G/LTE modems and network storage sharing. Key pros include simultaneous dual-band operation to reduce congestion, an easy-to-use web-based setup wizard, and built-in Quality of Service (QoS) for traffic prioritisation. However, notable cons include limited range on the 5 GHz band, the lack of automatic 3G failover, and restricted USB functionality where only one user can mount a shared drive at a time.
