The folks at Broadcom have not been willing to release any information on their 800.11g chips for fear of violating FCC regs. The required NDA would prohibit the release of the source. You can program both the transmit power and frequency if you have this. (I make no claim as to whether their concerns have any validity.) For that reason there has been no open-source support for these chips. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
