So much for hype: Becky Waring gets to the heart of performance in 802.11g gateways with proprietary speed boosting extensions in PC World: Waring performs real-world tests of units from D-Link (Super G), Buffalo (AfterBurner), and Cisco (SpeedBooster). She saw no interference between Atheros's Super G technology and Broadcom's AfterBurner. All three units produce throughput in the 22 to 24 Mbps range in her testing, versus about 18 Mbps for plain G. The top of the range offers significant improvement -- 33 percent--but it may still not be enough to warrant spending a few more dollars for.
