Flashing Router with DD-WRT Firmware

Posted on August 21, 2011 by Richard Huang

DD-WRT 官方 wiki 上有详细的刷机指南，不过因为它要照顾到多种可能性、可选项，使得文章的长度很吓人，其实刷机超简单，只有简单的三步。 1，下载一个适用于你的路由器的 firmware build。（如何选择合适的 build？） 2，重置路由器至出厂状态 使用浏览器打开路由器的管理页面，然后切换至 Administration -> Factory Defaults 功能页，在 Restore Factory Defaults 选项中选中 Yes，然后点击 Apply Settings 按钮。重置完成后，在出现的初始化页面上设置一个用户名和密码。 3，刷机 使用浏览器打开路由器的管理页面，然后切换到 Administration -> Firmware Upgrade 功能页，选中 After flashing reset to default settings，并选中你在第一步中下载的固件安装包，然后点击 Upgrade 按钮。等待数分钟，待刷机完成后，在出现的初始化页面上设置一个用户名和密码。

How to Choose DD-WRT Build for Broadcom Based Router

Posted on August 21, 2011 by Richard Huang

DD-WRT 支持多种路由器设备，其 wiki 上维护有一个 Supported Devices 页面，你可以查找你的路由器是否可以安装 DD-WRT 固件。本文假定你的路由器在支持列表中，且 CPU 是 Broadcom 的。 最简单的选择方式当然是 DD-WRT 官网的下载页面，但其上给出的推荐 build 通常都太老了。在 DD-WRT 的 FTP 中有很多 builds，但很难知道哪个 build 是最合适的，你可以逐个测试… 嘿嘿，工程量浩大、而且容易变砖。还好论坛中有一个专门的 Firmware Recommendations 贴，著名的 redhawk 同学根据测试给出推荐，通常都是很靠谱的，如果你懒得自己动手测试，这是一个很好的选择。 Package Type 根据安装包中的所含功能的不同，DD-WRT 固件安装包有很多不同的类型，比如：micro, mini, std, mega 等等。在 wiki … Continue reading →
