使用OpenWrt的原因

People install OpenWrt because they find it to be superior to the stock firmware of their router or embedded device.

人们安装OpenWrt是因为他们发现它优于路由器或嵌入式设备的库存固件。

Performance & stability 性能和稳定性

OpenWrt is designed by network professionals and others who care about the performance of their network. OpenWrt incorporates many algorithms from recent research that perform far better than vendor-supplied firmware.

OpenWrt由网络专业人员和其他关心其网络性能的人设计。OpenWrt结合了最近研究中的许多算法，其性能远远优于供应商提供的固件。

• OpenWrt is stable, and operates reliably for long periods of time. OpenWrt是稳定的，并且可以长时间可靠地运行。

• OpenWrt reduces latency/lag and increased network throughput via bufferbloat control algorithms. OpenWrt通过缓冲区膨胀控制算法减少延迟/滞后并提高网络吞吐量。

• Wi-Fi improvements support higher data rates and airtime fairness between stations. Wi-Fi 改进支持更高的数据速率和电台之间的通话时间公平性。

• Older devices are still supported by OpenWrt improvements (as long as RAM/Flash of your device can accommodate new releases) long after the manufacturer stops making updates. 在制造商停止更新很久之后，OpenWrt改进仍然支持较旧的设备（只要设备的RAM /闪存可以容纳新版本）。

Security 安全

OpenWrt is an open source software. Many developers from all over the world review the code before it's released.

OpenWrt是一个开源软件。来自世界各地的许多开发人员在代码发布之前对其进行了审查。

• No hidden backdoors left by hardware vendors. 没有硬件供应商留下的隐藏后门。

While many vendors only provide updates for your router/device until the newer model is released, OpenWrt supports all compatible models for as long as their RAM/Flash can accommodate new releases. OpenWrt延长了路由器的使用寿命。虽然许多供应商只为您的路由器/设备提供更新，直到发布较新的型号，但OpenWrt支持所有兼容的型号，只要他们的RAM /闪存可以容纳新版本。
