if u wanna try

ZTE modem connect to DLINK DIR615 and connect to TL-WDR4300 ?

u plug the lan cable at dir615 lan port and wdr4300 wan port, set wdr4300 using dynamic ip will do, no need extra configure

i know that,

previously i do like urs mention

terminal (port 1) -> dlink (wan port) and dlink (port 1) -> tplink (wan port)

dlink turn off wifi, but still use as pppoe dialer,
tplink change from pppoe -> dynamic ip

then it will automatic connected to internet once dlink success make the pppoe connection

any ip will do except the range use by dlink

eg, dlink use 192.168.1.1 mean that 192.168.1.x range cannot be used.
