DIR-855 Product summary

The good: True dual-band; great throughput performance; intuitive and responsive browser interface; gigabit LAN and WAN; easy to set up; supports separate wireless networks for guests; network activity display offers quick access to a variety of network information; convenient preset settings.

The bad: Middling range; confusing network activity display; expensive; bulky design; no print-serving or NAS functionality.

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.

DIR-855

DIR-855 Description

Out of the box, the D-Link DIR-855 looks like a differently colored D-Link DGL-4500 . (The DIR-855 is white, while the DGL-4500 is dark blue.) The DIR-855 has three antennas attached to the back of the router–not a good design, as they crowd the network ports. The antennae are, however, removable, in case you need to install an external high-power antenna for longer range. Like most D-Link routers, the DIR-855 is wall-mountable and also comes with a vertical mount base. Similar to the DGL-4500, the DIR-855 has a top-mounted, organic light-emitting diode (OLED) Network Activity Display (ONAD) that shows more than just the network’s connection status–the two navigation buttons display WAN, LAN, and wireless information via the little blue screen. However, in our tests, the screen timed out after a minute or two. The ONAD is fun to play around with at first, and is indeed useful in a number of situations, such as checking on the Internet connection, number of wireless clients, and so on, but in the long term, you might miss the regular LED status light found on most routers.

Like the name suggests, the D-Link DIR-855 comes with two Draft N 2.0 access points. One of them uses the ubiquitous 2.4Ghz frequency, while the other works in the new 5Ghz frequency; the two can run simultaneously. This is the first router from D-Link that offers true dual-band operation.

The DIR-855 gave a mixed performance in our tests. On our maximum throughput test, the router registered 101.7Mbps and 77Mbps for the 5Ghz frequency and 2.4Ghz frequency, respectively–both high, though not perfect, scores that bested the LinksysWRT610N, which came in at 101Mbps and 53.3Mbps.

User Reviews

azz710 said:Excellent wireless speed and reach. Excellent performance, in general. Fast, simple web-based configuration. Stable operation (no memory leaks, no need for periodic rebooting as with many other home routers).If you have the cash, buy this router and you will probably discover it will be the last router you buy for many, many years.
