簡介 BROADCOM BCM4702無線網(wǎng)絡(luò)處理器，這是一顆功能豐富、高度整合的處理芯片，其路由性能大約是基于ARM7的WLAN設(shè)備的5倍。BCM4702內(nèi)整合了2個10/100 Ethernet MACs、1個PCI/Cardbus控制器、1個USB控制器和1個PCMCIA host，這樣的設(shè)計使得OEM廠商可以根據(jù)不同需要開發(fā)具有不同功能的產(chǎn)品。BROADCOM BCM5325五口的交換器同BCM4702搭配使用，這種搭配也是BROADCOM所提供的參考設(shè)計方案之一。 :BROACOM的 4702 CPU（頻率為125MHZ）MIPS32內(nèi)核、內(nèi)存為SD 16M、FLASH容量為4M. |

這哪是開發(fā)板，明顯就是一個無線路由器的產(chǎn)品板 |

樓上的說的對. 對于只有幾百元的價格來說 ,這個板子用來學(xué)習(xí)LINUX的,很超值. 內(nèi)部已經(jīng)有BOOTLOADER,支持使用TFTP來燒寫程序. 下面這個地方可以找到全部的源代碼: http://www.linksys.com/servlet/Satellite?c=L_Content_C1&childpagename=US%2FLayout&cid=1115416836002&pagename=Linksys%2FCommon%2FVisitorWrapper |

LINKSYS的無線路由器 型號為:WRT54G 在各大城市的電腦城都可以買到. 另外,這個設(shè)計在好幾家公司都可以找到. 硬件是相同的.只是軟件界面不一樣. |

只有v1版本的才是，v2以上的硬件都換了 |

里頭的無線部分和主板接口是標(biāo)準(zhǔn)的嗎 |

MINI-PCI的標(biāo)準(zhǔn)接口 DD-WRT也提供代碼. 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. |
