While the IEEE committee is postponing the date of ratification of the 802.11n specification, the organizations and companies that have anything to do with the new wireless standard are already busy working with it. The certification process for devices supporting 802.11n Draft 2.0 was begun right after the second draft version of the 802.11n standard was approved of by the Wi-Fi Alliance.

We already tested one Wi-Fi Alliance Certified device in our labs (that was the D-Link DIR-655 router, see our article called D-Link Xtreme N Gigabit Router Review) and now we can tell you about another such product. It is the BR-6504n router from the Taiwan-headquartered Edimax Technology. This company isn’t as renowned as D-Link or Linksys, but is not inferior to them in terms of product range or company’s age. As for the quality of its products, we are going to check it right now especially as the company gave us a great opportunity to review not just a router but the whole 802.11n Draft 2.0 kit including a Fast Ethernet router BR-6504n, a USB-adapter EW-7718Un, a CardBus-adapter EW-7708Pn, and a PCI-adapter EW-7728In.

So let's get started!
