Openwrt doesn't work dhcp

Question

I have my ISP Modem connect to my TP-Link (AC1750 v2). And have bridge connection between LAN and WAN (ISP Modem). This is working fine, but I have to manually setup the IP and the gateway, for example: my PC IP: 192.168..1.16. Subnet Mask: 255.255.255.0 Default gateway: 192.168.1.3

But can't connect (wired o wireless) without setting the IP manually.
