D-Link WiFi Certifications List

I heard Wi-Fi CERTIFIED n products can cause interference problems with other Wi-Fi networks. Is this true?
All 802.11n certified routers must now implement a good neighbor policy. The router can support 20 and 20/40 channel width, however, will fall back to 20mhz only if the router detect another device nearby running on the same band. In other words, if your neighbours are running a 2.4ghz network. your router will fall back to 20mhz which negotiates to usually between 130-150Mbps. Older revisions of 802.11n routers did not implement this and thus will show up to 300Mbps. Without getting too technical, if this wasn't implemented, everyone would be cutting everyone elses signal and causing severe wireless disconnections.

If you want more information do a web search for "20/40 coexistance" should give you more technical information.
