D-Link DIR-655 Xtreme N Gigabit Router

D-Link DIR-655 Xtreme N Gigabit Router

Editors' rating

Very good

7.6

out of 10
  • The good: The D-Link DIR-655 Xtreme N Gigabit Router displayed lightning-fast performance in short-range and mixed-mode tests; it offers Gigabit LAN ports and the latest in wireless security.
  • The bad: Very expensive; based on an unfinished spec.
  • The bottom line: The D-Link DIR-655 Xtreme N Gigabit Router is the fastest we've seen, but we're still reluctant to recommend it as it's based on an unfinished wireless spec.

The D-Link DIR-655 Xtreme N Gigabit Router is one of the latest Draft N routers to the market. Believe us when we say it packs a punch. It's by far the fastest 802.11n router we've tested. At $180, it's also one of the most expensive. We've been reluctant to recommend Draft N routers because the spec isn't final and so far, we haven't seen the throughput speeds offered by the standard. There's no guarantee the Draft N products will comply with the final spec, so our advice for now is to wait until we see products actually based on the final spec, probably around midsummer.

Combined with the D-Link Xtreme N Notebook Adapter, we saw the best throughput speeds to date for any router tested here at CNET Labs. Ready for the numbers? In our 10-foot maximum throughput test conducted with an Ixia Chariot console, the average throughput was 112.56Mbps. This is a whopping 30 to 40 points higher than most draft 802.11n routers we've tested in the past. Mixed throughput (with an 11g client) clocked in at 77.42Mbps while throughput at long range (200 feet) was 33.33Mbps.

Note: *The Belkin N1 and the Buffalo AirStation Nfiniti routers don't allow for single-mode operation, so they have no scores in this test.
