D-Link Xtreme N Duo Media Router DIR-855 review: D-Link Xtreme N Duo Media Router DIR-855

Performance
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.

Even better, the D-Link DIR-855 topped our charts on its range test, where we tested the device's broadcasting signal at 200 feet. Its 2.4Ghz frequency throughput, 66.5Mbps, performed second only to its own 5Ghz frequency throughput, which came in at a whopping 85.7Mbps--the highest in Draft N 2.0 range throughput performance we've seen by far.

In our mixed-mode test, in which the router supported both Draft N 2.0 and legacy 802.11b/g clients at the same time in 2.4Ghz frequency, the D-Link DIR-855 finished about average, at 58.5Mbps.

All in all, the DIR-855 is a great performer, unless you need broad range. In our test environment (which is not the best for range), the router was only able to maintain a stable connection within about a 250-foot radius--20 feet shorter than the Linksys WRT610N's range.
