简介 BROADCOM BCM4702无线网络处理器，这是一颗功能丰富、高度整合的处理芯片，其路由性能大约是基于ARM7的WLAN设备的5倍。BCM4702内整合了2个10/100 Ethernet MACs、1个PCI/Cardbus控制器、1个USB控制器和1个PCMCIA host，这样的设计使得OEM厂商可以根据不同需要开发具有不同功能的产品。BROADCOM BCM5325五口的交换器同BCM4702搭配使用，这种搭配也是BROADCOM所提供的参考设计方案之一。 :BROACOM的 4702 CPU（频率为125MHZ）MIPS32内核、内存为SD 16M、FLASH容量为4M. |

楼上的说的对. 对于只有几百元的价格来说 ,这个板子用来学习LINUX的,很超值. 内部已经有BOOTLOADER,支持使用TFTP来烧写程序. 下面这个地方可以找到全部的源代码: http://www.linksys.com/servlet/Satellite?c=L_Content_C1&childpagename=US%2FLayout&cid=1115416836002&pagename=Linksys%2FCommon%2FVisitorWrapper |

LINKSYS的无线路由器 型号为:WRT54G 在各大城市的电脑城都可以买到. 另外,这个设计在好几家公司都可以找到. 硬件是相同的.只是软件界面不一样. |

MINI-PCI的标准接口 DD-WRT也提供代码. http://www.dd-wrt.com/ DD-WRT is simply a project which was originally based on the official GPL Sources of Sveasoft Alchemy. but turned later to a OpenWRT Kernel vase firmware variant. Due the nature of GPL based projects, this firmware will be also release under this license. Initially i wrote this modification to make it possible, to use the Linksys WRT54G/GS inside our Wireless Lan network as cheap replacement for our professional Lancom and Orinocco access points. so what was missing? first, we are using radius authentication with a CENTRAL account management inside our network for user authentication. There is already a radius application available for OpenWRT, but openwrt was no choice since it is not user friendly for a non COMPUTER professional without any linux knowledge. so i just integrated it with some small enhancements in the alchemy SOFTWARE. my wrt-radauth modifications: radius server timeouts will not be a problem anymore. a client is authenticated just up to the point, the server says really 'no'. a connection timeout will not have any influence to this workflow. additionally i found it really helpfull to use a external filesystem DEVICE inside the WRT. my choice was a samba client since it is useable on any COMPUTER platform. you can easilly mount a windows network share into the wrt and additionally its also possible to start a script after mounting from this DEVICE. but the work was not over. also if currently the server/client watch function is still under development, i already implemented the RFlow traffic monitoring and management tool into the web interface. this tool is already inside DD-WRT, but you have to start it manually and so far it looks unfinished. (daemon mode does not work). so i finished it and yes now its working inside my DD-WRT and you can configure it out from the administration window. |
