Question and answer
How has the introduction of wireless networking changed how we look at networks today?
Wireless networks today are faster, more secure, and more reliable than their predecessors. [ But to some extent Wi-Fi is a victim of its own success: Search for a Wi-Fi hotspot these days, and you may find a dozen networks competing for the same 2.4GHz bandwidth-so nobody gets a good signal. At the same time, changes in the way we use networks demand better performance than ever. Exacting applications such as network backup, high-definition video streaming, BitTorrent downloading, and VoIP can choke even the fastest Wi-Fi: At best, a draft-2.0 802.11n router delivers a little over 100
megabits per second in real-world throughput. If multiple Wi-Fi clients claim a share, performance can rapidly- and, in the case of streaming video, visibly- deteriorate. We believe that many people would benefit from a hybrid network incorporating both technologies; fortunately, this isn't difficult to set up (see "Adding Powerline to Your Network Is Easy"). With regard to product quality, we're happy to report that all of the draft-2 802.11n Wi-Fi routers we tested rated at least Good overall, and several earned marks of Very Good. This was not the case in our previous round of wireless networking tests, an indication that the category is maturing. The Belkin N+ and the D-Link DIR-655 scored highest, thanks to very good performance and setup tools, along with valuable features such as support for USB drive sharing and a security-conscious guest access mode. ]
