When the Wi-Fi repeater function is enabled, the IP address is still assigned by the router. When some brands of wireless routers receive frequent connection requests, they may refuse to assign IP addresses, resulting in Wi-Fi repeater unable to connect. It is recommended to restart the route or try to connect again after waiting for a period of time. In some scenarios, the hub may switch back and forth to connect different routers when multiple routers in the same WLAN share SSID but use different channels (such as office environment), once the channel is changed, the devices under repeater can not establish the corresponding IP relationship with the new route, resulting in the Wi-Fi repeater being unable to communicate. It is recommended to use the Wi-Fi repeater function only in a single router environment.
