D-Link says DIR-855 will ship…really!
While arranging my DGL-4500 review sample with D-Link, I asked them about the rumors that the long-delayed DIR-855 has been placed on "indefinite hold". D-Link told me that the product is still alive and that the target ship date is now "end of year 07 or early year 08".
D-Link DIR-855 Getting Closer?
During my routine check of the Wi-Fi Alliance 802.11n Certified product list, I found that the mythical D-Link DIR-855 Dual-Band Draft 11n router received its 802.11n Draft 2.0 certification back on October 3. Shame on me for not catching this before now.

Hole discovered in Wi-Fi 802.11n Draft 2.0 Certification test
SmallNetBuilder has discovered a hole in the Wi-Fi Alliance's 802.11n Draft 2.0 test suite that can allow Wi-Fi Certified products to interfere with existing wireless networks, in direct violation of a mandatory Certification requirement.
A long-running battle in the standard has been whether to allow the use of "wide-channel" operation in the 2.4 GHz band that is used by the majority of Wi-Fi products. The mode, also referred to as "channel bonded" or "40 MHz bandwidth" mode, uses up two of the available three non-overlapping channels in the band, making it impossible to avoid interfering with other wireless networks operating in the center of the band.
Interference from draft 802.11n channel-bonded networks can, at worst, render 802.11b and g wireless networks inoperable and, at minimum, cause slowdowns and unreliable connections.
