Tonight we’ll be taking a look at the latest home networking product from D-Link Systems, Inc.  D-Link is one of the world's leading manufacturers of Networking, Connectivity, and Data Communications products.  Although they are mainly known for their commercial products, D-Link has also made a name for themselves in the Digital Home Connectivity market.  With a wide array of products available from standard Network Interface Cards to Switches and Hubs, D-Link has secured a solid share of  the home networking market.  D-Link has been successful competing with such companies as Intel, NetGear, and 3Com.  Now D-Link is trying to secure a foot hold in the wireless market with the release of the DWL-920 USB Wireless Network.

As the personal computer has become more popular and affordable, more & more families are purchasing additional PC’s for their homes.  Often with that, comes the dilemma of getting those computers to share a common Internet connection or share common files.  Most of us that are more computer savvy than the average user, would have no problem picking up a hub and a few NIC’s and networking our PC’s together.  But to some inexperienced users this can seem like a daunting task.  Even the simplest home networking package requires the opening of the computer, some configuration and perhaps some tweaking too.  Now imagine a novice user attempting this.  This is a tech support nightmare when the casual or inexperienced user opens their system.  What D-Link has done with the DWL-920 USB Wireless Network is keep it as simple as possible, avoiding the average user from getting in way over their head.   Let’s take a look at the specs and see what this kit has to offer…
