The D-Link DWA-645 RangeBooster N 650 Notebook Adapter is the companion card to the DIR-635 draft N router. The pair performed fairly well against its draft N competition but is still a way off from fulfilling the promise of 802.11n. At $99, the adapter is priced on a par with other notebook adapters. And as we've said in every other draft N review, it's too early to invest in 802.11n networking gear. You're better off waiting until the spec is finalized (we're hearing mid-2007) to see how the products based on that version fare.
Like most notebook adapters, installing the DWA-645 is a simple task. The included quick install guide cautions against inserting the card without first installing the drivers from the included CD. The installation wizard walks you through the process of connecting to a wireless network and configuring security settings. The quick install guide also gives a basic overview of Windows XP's wireless utility, including how to turn it off, should you opt to use D-Link's utility.
There's not a lot to be said about the design of notebook adapters. The DWA-645 is typical in that the part that sticks out of the card slot is thick, black plastic and houses two small LEDs, one to indicate a connection and the other to indicate activity.
