我刚买了一台新路由器，TP-LINK TL-WR1043ND V2.1，现在遇到了问题。说实话，我不知道这是路由器的问题还是我的电脑的问题，所以我才在这里发帖。
路由器通常工作正常：所有其他设备都可以毫无问题地连接到它，甚至我的笔记本电脑也可以通过以太网电缆连接到它，只有当我尝试通过 Wi-fi 连接时才会出现问题。然后发生的事情是我的笔记本电脑连接到路由器，几秒钟（2-3）后我可以连接到路由器，但突然所有数据包都丢失了，无论我尝试连接到什么。奇怪的是，我的笔记本电脑显示我仍连接到网络。
我对旧路由器（TP-Link TL-WR542G）没有任何问题。
我尝试禁用路由器上的 802.11n 协议，但没有帮助。

答案1
在路由器上安装OpenWrt解决了问题。
