I have configured TL-WR940N in range extender mode. My main router that it is connecting to is a AX1500 Wi-Fi 6 Router. The WR940N is connected to the main router and I can ping it. However, whenever a device tries to connect to the wireless via the WR940N the connection fails to assign an IP due to a DHCP error. I've reconfigured the WR940N, rebooted both routers but I can't get the range extender to work to connect devices.
