The network rate is slow when two routers are cascaded

The mobile phone or computer may have connected to the Wi-Fi of the secondary router. The Wi-Fi signal attenuates during transmission. If the distance between the two routers is too far, the signal may become weak, thus affecting the network rate. When you log in to the web-based management page of the primary router, a message will display, indicating that the two routers are too far away from each other. Shorten the distance between the two routers as prompted.
