两个路由器连上了主路由器但是发不出网络？

要解决此问题,需确保以下事项：

1. 确保已正确设置以WiFi方式进行数据传输，通过两个路由器同时连接，将其中任何一个路由器作为主路由，并在另一个路由器中设置为从路由，第二个路由器应首先插入并充满电，而不是仅将它接入主路由器的LAN接口。 为了修复此错误,您可以采取以下两种方法：

   步骤1：动态IP方式（初始情况下为主路由器,后续从路由器作为从路由）

   • 从路由器开启电源，无需连接到主路由器LAN口，请先断开主路由器对来自该路由器的LAN端口的连接,将其重新设置为从路由状态。

   • 激活计算机与从路由器上的任意一个LAN口连接，在此过程中，您可使用Windows操作系统的“网络”应用程序或Mac OS X系统的“系统偏好设置”来访问并设置路由器设置页面。

   • 在主页设置中启用动态IP功能，通过输入默认地址（如192.168.1.1）并选择对应的子网掩码（如255.255.255.0），以及设置其他配置参数（如SSID（网络名称）、加密类型和密码）,即可完成此设置过程。

   • 保存更改并重启设备，再次打开设置页面后,更新主路由器LAN口连接至从路由器的WAN端口以便获取数据流。

   步骤2：无线AP方式

   • 将所需电脑连接到从路由器的LAN端口，确保其不是WAN端口（因为从路由器不支持有线连接到WAN端口），一般情况下，从路由器通常提供有线接口以支持本地连接，包括LAN口（一般位于路由器底部或右侧）。

   • 首先关闭路由器的DHCP功能，在Internet Explorer或Google Chrome等浏览器的“网络”设置窗口中找到“DHCP服务器”选项，然后取消勾选（若已启用）与当前无线信号源（如移动热点、笔记本电脑等）关联的自动分配IPv4地址和DNS服务器的功能。

   • 仅在客户端设置路由器IP地址和DNS服务器，如需手动指定，可以按下无线路由器的“无线设置”按钮，切换至网络设置界面，找到“IP地址”或“静态ARP”，然后输入当前网络的IPv4地址及其子网掩码（通常为255.255.255.0）,并为它们指定IPV6地址和DNS服务器。

   • 然后进行下一步设置，即为主路由器设定一个新的WiFi名称、加密类型和密码,这些信息应在路由器的背面或设置菜单中找到。

   • 在主路由器的无线设置界面，确认所有配置选项均无误且以加密方式连接设备，确保已经链接成功（无线AP需要运行适当的无线驱动程序）。

   • 只需确保两台路由器之间的距离和环境适宜以接收信号强度（具体取决于您的网络覆盖范围和地理位置），让两个路由器正常工作,即可实现连通性问题。

"Two routers have been connected to the primary router but cannot establish a network connection? A possible reason for this issue is that you have not set up the wireless network in the correct way. To resolve this problem, follow these steps:

1. Ensure that both routers are properly connected using WiFi data transfer. By placing one of them as the primary router and setting it as the secondary router from another, we will see that the second router will be set up as a from-router.

   To fix this error, follow these two methods:

   Step 1: Dynamic IP mode (initially as the primary router, later as the from-router)

   • Connect the from-router to the power supply after unplugging it from the primary router's LAN port. Unplug the primary router from the LAN interface and reset it to default settings.

   • Launch Windows or macOS operating systems' "Network" application or Safari on a Mac to access and configure the router settings page.

   • Enable dynamic IP function by entering the default IP address (e.g., 192.168.1.1) along with the appropriate subnet mask (e.g., 255.255.255.0). If DHCP is enabled, select any available local IP address and modify the DNS server configuration.

   • Save and restart the device. Reopen the router settings page again, update the primary router's LAN port connection to the from-router's WAN port to receive data flow.

   Step 2: Wireless AP mode

   Connect the desired computer to the from-router's LAN port, ensuring it is not an external WAN port (since from-router does not support wired connectivity through a WAN port). Most routers typically provide an Ethernet interface, including the LAN port, for local connections, such as laptops or desktops.

• Disable the DHCP function on the from-router. Open Internet Explorer or Google Chrome's "Network" settings window to locate the "DHCP Server" option. Uncheck the previously associated automatic assignment of IPv4 addresses and DNS servers with your current wireless signal source (e.g., mobile hotspot, laptop), if applicable.

• Enter the desired LAN IP address and subnet mask manually for the from-router. If you need to assign an IPv6 address and DNS server, follow the specific instructions for the from-router model in the documentation.

• Configure the primary router's WiFi name, encryption type, and password. These information can be found on the back or in the network settings menu of the from-router.

• Confirm that all configured options are accurate and use encryption to secure the devices connected to the from-router. Ensure that the from-router is functioning correctly, as it should provide stable connectivity when used together with the primary router.

• With the setup complete, ensure that the distance between the two routers and the environment conducive to strong Wi-Fi signals (depending on your network coverage and geographical location) allow for adequate reception by both routers. Observe if they successfully establish a communication channel, confirming that the issue has been resolved."

在实施上述步骤之前，确保确保主路由器已正确启用无线局域网，并且避免将主路由器的WAN端口与其他路由器的LAN口相连以防止无线干扰，请仔细检查IP地址、子网掩码、MAC地址和其他配置选项,确保与文档中的指导一致。
