I have a ArcherC7 as a main router, to which Ubiquity EdgeSwitch8 is connected, to which Unifi AP providing MAINWIFI is connected.
I have also older router TP-LINK wr2543nd, which I succesfully patched with openwrt firmware.
I would like to accomplish that WR2543ND router connects to MAINWIFI and becomes switch for devices connected to its LAN ports or to its WIFI.
I tried to follow instructions here https://openwrt.org/docs/guide-user/network/openwrt_as_clientdevice
but it doesn't work
Anyone please have a good setup guide how to accomplish what I need.
Thank you in advance.
