Hello,have TP-Link TL-WR843N/ND v1 with LEDE Reboot 17.01.6 r3979-2252731af4 / LuCI lede-17.01 branch (git-18.201.27126-7bf0367) as spare router and have Netis WF2419 as main router wich is as main,because by he"s WAN MAC getting internet via DHCP to mine house,soo question what configure on tp-link with LEDE/Openwrt that he can work as replace for Netis?firmware i can change with this is no problem.Heared something about MAC rewrite/spoofing.
I guess this is your inquiry.
i think its need to make more actions in section Network.But how to know of wich port?because there not writed that eth0 is as WAN port.
little update,on router installed firmware from this Custom Builds LEDE v17.01.7 & libreCMC v1.4.5 for TP-LINK WR740N(D) WR741N(D) WR841N(D) WR941N/D) All Versions internet working,but not good thing is that one device sat receiver with linux,getting settings from other switch-dumb ap,not from main router.Now network looks like ISP lan cable with internet with DHCP-->main router WR843ND->simple switch-->dumb ap with not openwrt->simple p2p ubiquiti set->dumb ap with openwrt in other building TP-Link TL-WR740N/ND v4.
