| The Bottom Line | The D-Link Xtreme N Dual Band Gigabit Router DIR-825 is a stable performer with great features and an excellent Web interface. The outdated and bulky design, relatively short range, and merely average throughput, however, lessen its appeal. | With the latest firmware update, the D-Link DIR-655 is arguably one of the best among single-band Wireless-N routers on the market. | Though not perfect, the Asus RT-N66U Dark Knight Double 450Mbps N Router would make an excellent network gateway for home and small-office environments. | Running Cisco Connect Cloud firmware, the Linksys Smart Wi-Fi Router EA4500 makes an excellent router for those who want a fast and advanced home network that's easily manageable from anywhere. | The Asus RT-AC66U is an excellent router and is currently one of the best options among those that support the latest 802.11ac Wi-Fi standard. | Basic specs |
