Verdict

The D-Link DIR-645, also known as the Whole Home Router 1000, is a single-band Wireless N router featuring 300 Mbps speeds on the 2.4 GHz frequency and a unique cylindrical design with six internal SmartBeam antennas for improved coverage. Its primary hardware includes four Gigabit Ethernet LAN ports, one Gigabit WAN port, and a USB 2.0 port supported by SharePort Plus for network sharing of printers or storage. Key pros include its exceptional long-range performance, IPv6 readiness, and built-in DLNA media server for seamless streaming to compatible devices. However, its main cons are the lack of a 5 GHz band, which makes it more susceptible to interference in crowded areas, and a web interface that some users find unintuitive or dated.
