This software serves as a driver for Atmel AT76C503/505A chipset based USB Wireless LAN adapter.
This software is a driver for USB wireless LAN adapter based on the Atmel AT76C503/505A chipsets. It is specifically optimized for use with popular Micronet SP907BB adapters. Users can expect minimal issues and improved results compared to similar drivers available on sourceforge.net.
However, there are currently some limitations to this driver. It is unable to operate in promiscuous, monitor or station mode and does not support libpcap. As a result, it cannot be used with tools such as Kismet or Airsnort and cannot function as a WLAN access point. These restrictions are imposed by the firmware of Intersil radios, which is outdated and has more limitations. For additional information, see the chipsets page.
Fortunately, support for 2.6.x kernels is available in the main tree (version 0.13+). The driver has been tested to function with USB host controller drivers such as usb-uhci, uhci and usb-ohci. It has also been tested to work simultaneously with more than one adapter.
Recent updates to the software include adding a switch to manage Intersil firmware 0.84.0, which does not send FCS in rx data. There is also a new module at76c503-rfmd-acc.o for SMC2664W, which requires special firmware (Accton OEM products). Additional regulatory domains, such as MKK1 and Israel, have been added. Rudimentary ethtool support for SuSE's future hotplug is now available, as well as a nickname ioctl for iwconfig. There is also a test for valid channel in reg. domain, big endian patch (by Kevin Cernekee), and changes to defines in ieee802_11.h. Unsupported iwconfig modes such as monitor and master are now suppressed according to a patch by Pavel Roskin.
