OrangeWare offers $15 driver to Mac users to pick up extra speed: We here at Wi-Fi Networking News remain dubious about the efficacy of Atheros's Turbo mode, which bonds two Wi-Fi channels and has been shown in some studies to cause interference. Atheros continues to assert there is no interference. In either case, Mac users now have access to many more options for wireless networking through the OrangeWare driver, which can support a/g cards that use Atheros chips, including the Super G features, which include compression and frame bursting, among other non-radio-frequency improvements in speed among similar devices. A free trial version is available for download.
The driver lists support for a couple dozen cards (PC Cards and PCI cards) and works with Mac OS X 10.2 or later. These cards are typically less than $50 or even as low as $30, while an internal AirPort Extreme Card--if available for a given model--is $100. The driver only shows WEP, not WPA support.
