Why does the Internet not work through the switch after the asus router?

Question

ASUS

hello everyone, the situation is, there is a main asus router, it has another asus router in AP mode (access points), in the lan port of which a switch is connected (TP-link TL-SF1008D), nothing works after the switch if it is directly connected to the AP to connect the PC it works, why doesn't the switch distribute anything? Is this not possible or is the config wrong?
