| The Bottom Line | The D-Link Xtreme N Duo Media Router DIR-855 is a stable performer with excellent Web interface. But because it comes in a bulky, old-school design, has a relatively short range, and carries a hefty price tag, consider waiting for the price to drop before investing in this router. | 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. | 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 The outdated and bulky design, relatively short range, and merely average throughput, however, lessen its appeal. | 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. | Though not perfect, the D-Link DIR-857 HD Media Router 3000 makes a great router for homes thanks to its top-notch performance on the 5GHz band and a nice set of features. | Basic specs |
