INTRODUCTION


With demands on bandwidth usage continuing to increase in my household, I decided it was time to look at a higher speed wireless network.  The network I was using before was a network from Edimax (reviewed here).

With that network, Internet and file sharing worked well for small files, but when streaming videos off of my server to the wireless clients, things got choppy at times.  So I started my search for a faster wireless solution.  This led me to the local Best Buy where I picked up a D-Link DI-784 Wireless Router.  I chose this router due to the ability of it being able to work with 802.11a/b/g.  This would let me set up the network independent on the cards I used for the wireless network.  This router also has full support for WPA security, which is stronger protection than WEP which also is a plus.
